Confounded about what all the diverse specs mean when contrasting distinctive convenient charges? Pondering what an amp, amp-hour, or milliamp-hour really implies? We separate this and more to enable you to make sense of which compact power pack is the best fit for you, why you may even need one, and what to search for when looking for another one. Be that as it may, in the event that you simply need to perceive how singular items did and which convenient chargers dominated the competition, head on over to our extensive compact battery pack survey here!
Stage 1: How Big a Battery Do You Need?
The main thing you will see when contrasting diverse convenient chargers is the distinctive limits accessible. This is normally estimated in milliamp-hours, with the "milli-" prefix making this unit 1/1000 of an amp-hour. Incidentally, most battery packs are really a few thousand milliamp-hours, implying that a 10,000 mAh or 20,000 mAh pack could be composed significantly more briefly as 10 Ah or 20 Ah. In any case, that is the standard that pretty much every producer has picked for buyer gadgets, so we will stay with that.
Basically, the milliamp-hour limit alludes to the aggregate sum of electrical vitality that every battery pack can store. In particular, it states what number of milliamps of electric flow every battery pack can accommodate 60 minutes. To utilize an auto relationship, the milliamp-hour rating is much the same as how extensive of a gas tank the battery has.
Since you have a smart thought what the limit rating alludes to, it's an ideal opportunity to figure out which measure battery is the best fit for you. While a bigger battery can clearly charge a larger number of gadgets a greater number of times than a littler battery, greater isn't really better with regards to these items. As a battery's ability expands, its physical volume, weight, and cost more often than not go with the same pattern.
In the event that you are simply searching for a battery to finish off your cell phone by the day's end or convey as a reinforcement on the off chance that you neglect to charge your telephone one day, we would prescribe a 5,000 to 10,000 mAh item. These ought to have the capacity to charge a solitary cell phone 1-3 times and are generally little enough to be conveyed in a pocket or tote with no critical uneasiness or weight gain. These littler power packs additionally revive essentially quicker than their bigger brethren.
On the off chance that you more often than not convey two gadgets and need to guarantee that you can charge them two totally, you might need to scrutinize to a 10,000 to 15,000 mAh pack. You can most likely escape with a 5,000 mAh pack in the event that you are charging two littler gadgets, similar to a work and individual telephone or a cell phone and smartwatch/wellness tracker, however you unquestionably need to scrutinize in the event that you are charging a bigger gadget, similar to a tablet. Presently, it's solitary important to survey on the off chance that you routinely need to charge both of your gadgets or can't chance having it is possible that one kick the bucket on you. On the other hand, battery packs this size can as a rule charge a solitary standard cell phone 3-5 times, so this size may be a decent choice for short outings where you probably won't approach an outlet, for example, an end of the week outdoors or exploring trip, or in the event that you would prefer not to need to energize your battery pack each time you utilize it. You can likely escape with charging packs of this size once per week or each couple of days, on the off chance that you are just utilizing it to charge or finish off a solitary telephone.
In any case, these bigger packs — particularly the 10,000 mAh models — can be more unwieldy to convey and are generally much more qualified for a tote, knapsack, or PC case, instead of a pocket.
At last, you should take a gander at the 15,000 mAh and up models in the event that you have to charge a huge amount of gadgets every day or on the off chance that you are anticipating going an all-encompassing timeframe without access to a charger. Seven days in length exploring or other boondocks trip rings a bell, where you need to charge your telephone or camera every day. Essentially, any multi-day circumstance where you have to routinely charge a gadget and won't have any entrance to control is a decent possibility for the biggest convenient power packs.
Being Prepared
The biggest power packs (20,000 mAh+) are an incredible thing to add to a first aid pack for power blackouts or even other catastrophic events. You ought to intermittently check the battery and finish it off at regular intervals, as they can gradually exhaust their charge when put away for significant lots of time.
In any case, it is imperative to hold up under at the top of the priority list on the off chance that you are getting one of these beast packs to charge various gadgets, you should remember that you might be constrained by the quantity of USB yield ports on the gadget — utilizing a USB-splitter isn't generally prescribed — and the most extreme conceivable yield of the battery pack, which drives us to our next theme.
Stage 2: How Much Current?
Since you have selected which estimate battery pack you require, it's imperative to check what the most extreme release rate of the battery is and if the rating is shared between all the USB ports or for every individual one. Proceeding with our auto similarity, if the milliamp-hour rating is proportional to the extent of the gas tank, the release current would be generally keeping pace with how quick you drive or — all the more nearly — how rapidly you are pulling gas from the tank. The quicker you pull the gas, the speedier the tank will drain, with a similar remaining constant for battery packs.
This is essential to check for the battery pack that you mean to purchase, as it is genuinely simple to surpass the most extreme rating on a few packs, especially in the event that you are anticipating charging numerous gadgets at the same time. The most up to date cell phones can attract up to 2.4 amps when they are charging at their quickest speed, with bigger gadgets drawing considerably more power. A battery pack that has a release rating not exactly the most extreme power draw of your battery pack may at present charge it, however it will take essentially more. For instance, a battery pack evaluated for 1 amp discharger will likely take something like twice the length you are utilized to charge your cell phone and will charge bigger tablets considerably slower, if by any stretch of the imagination. A pack appraised for 2.4 amps will for the most part charge your telephone at a practically identical speed to it being connected to an ordinary divider attachment with a brilliant divider block.
Notwithstanding, on the off chance that you plug two cell phones into a battery pack that is appraised for 2.4 amp release that is shared among the ports, the two telephones will charge much slower than run of the mill and two tablets will charge infuriatingly gradually.
On the off chance that you are anticipating charging various gadgets, you need to search for a pack evaluated for at any rate 3.4 shared amps for two telephones and knock it up to 4.8-5 amps of shared release in the event that you need to attach different tablets or similarly vast electronic gadgets.
Once in a while, the biggest power banks will have a settled sum for every port, for example, two 2.4 amp USB ports for tablets and a 1.2 amp port for littler gadgets, so you should ensure your planned utilize lines up with that. For instance, this setup wouldn't be extraordinary for charging three high power gadgets however would be incredible for charging a cell phone, tablet, and wellness tracker.
Stage 3: Any Extra Convenient Features?
Since you have made sense of what the electrical attributes of your ideal versatile charger ought to be, it's an ideal opportunity to consider any extra highlights that can enable you to limit your decision between your last competitors.
The three highlights that we observed to be the most valuable are worked in gadget links, worked in charging plug, and an implicit spotlight.
On the off chance that you realize that you are continually going to charge a specific gadget or gadgets that share a similar kind of charging association, it pays to get a convenient battery that has a worked in link.
For instance, on the off chance that you are continually charging your iPhone and iPad, getting a power pack with a lightning link incorporated appropriate with it implies that you can't ever overlook the link and a coordinated link for the most part makes for a substantially more minimal in general bundle, contrasted with conveying one independently. Furthermore, this battery packs typically likewise have a USB port, so you aren't completely secured into the assembled charging association in the event that you have to charge an alternate gadget.
Similar remains constant for battery packs that have a standard divider plug worked in for energizing.
This is our most loved comfort include, as it blocks the requirement for conveying a different charging link and a USB divider connector. It makes them substantially more helpful to convey and keeps you from overlooking either the link or the divider connector.
At last, a portion of these battery packs have a worked in spotlight. This isn't exactly as helpful with a portion of the littler packs, however it is a pleasant component on the bigger packs which are typically utilized when you are in the boondocks or other remote spots. We didn't discover it as valuable with the littler, consistently convey packs, as we normally wanted to utilize the electric lamp on our telephones.
End
Ideally, this guide has given you a superior comprehension of the intricate details of these items and allowed all of you the instruments you have to select the ideal convenient power pack. On the off chance that you are searching for more data on how we positioned and scored these items, you can look at our How We Test article for a definite portrayal of our testing conventions or investigate our Portable Charger Review to see which ones we thought are the most perfect out there!
How We Tested Portable Chargers
Considering how we positioned and scored convenient chargers? Initially, we did tons and huge amounts of research and investigation, at that point picked the most encouraging items to test straight on. We charged a wide range of things with these items — everything from cell phones to smartwatches. Moreover, we additionally estimated the genuine yield and pushed these items as far as possible utilizing an advanced multimeter and a sham resistive electrical load, and also timing to what extent every one took to energize. Beside the electrical parts of these batteries, we likewise evaluated and made a decision about precisely how versatile these compact USB chargers are and how much less demanding and more helpful they can make your regular day to day existence. We stepped through the majority of the exams we did and assembled them into four weighted rating measurements, with our correct methods plot underneath.
Conveyability
Justifying 40% of the aggregate score for every compact charger, compactness is a crucial quality of these items, as the name would propose. For this test, we gauged the aggregate volume and the heaviness of every battery pack, at that point scored them as needs be.
While there is a slight connection between's battery pack size and execution in these two tests, we found that a few packs have uncontrollably extraordinary sizes and weights, regardless of having the equivalent recorded limit.
We additionally evaluated and scored that it is so agreeable to bear these items in your pocket. We had analyzers stroll around and sit with every battery pack in a front and back pocket on a couple of pants, looking at how every battery pack felt next to each other and taking note of if there were an especially uneasy weight focuses. We chose a couple of coolly fitted pants for this test, as we felt they were a decent center ground, with other baggier attire effectively fitting the majority of the power packs without issue and anything more tightly basically blocks you from conveying the vast majority of these items in your pockets.
Limit
For our ability metric, which establishes 30% of the last score for every compact battery pack, we directed two separate tests. In the first place, we needed to test the maker claims for every battery pack. The majority of the items in this audit had a type of case of each pack having the capacity to charge certain telephones a specific measure of time.
We utilized a Samsung Galaxy S8 as a test telephone, charging it the greatest number of times as we could off of each completely charged battery pack and scored every item dependent on in the event that it surpassed or missed the mark concerning its showcasing claims.
For our second test, we took a gander at what the genuine limit of each pack is, scoring dependent on what the asserted limit of every convenient charger is. We quantified the limit by completely charging every item, at that point releasing into a fake load through a computerized multimeter. This fake load given us a chance to set the current attract to the greatest that each pack could deal with, with the meter timing to what extent the pack had been releasing for — and helpfully ascertaining the aggregate vitality released for us appropriate on the screen.
On the off chance that this sounds somewhat specialized, it knows a smidgen about how these items are appraised. These versatile power packs are appraised in some number of milliamp-hours, which for those that are new, is a proportion of aggregate vitality and alludes to how much power each pack can hotspot for 60 minutes. You can think about an amp, or ampere to utilize its full name, as the rate at which power is conveyed, so increasing that by some measure of time gives you the aggregate electrical vitality conveyed. An amp is a significant huge measure of electrical flow, so for most buyer items, we typically connect the "Milli-" prefix, signifying 1/1000 of an amp. For instance, a 10,000 mAh module is hypothetically evaluated to have the capacity to release at a rate of 10,000 milliamps (or 10 amps) for 60 minutes, or at a rate of 20,000 milliamps (or 20 amps) for 30 minutes. For reference, most present day tablets charge at a rate of 2.1-2.4 amps, so a 10,000 mAh pack ought to have the capacity to charge one of these gadgets for very nearly five hours. Practically speaking, we observed this to be a long way from the case.
Included Convenience
Next, we took a gander at how advantageous every convenient battery pack is to utilize, basically centered around if there are any extra highlights that made them especially simple to utilize. Altogether, this gathering of tests is in charge of 20% of the aggregate score.
In the first place, we granted focuses dependent on what number of gadgets you can charge at the same time on every battery pack. We likewise considered the greatest yield of every charger, granting the most indicates models that could deal with charging different eager for power gadgets immediately, similar to tablets or the biggest cell phones.
We at that point took a gander at any inherent highlights, to be specific worked in charging links for different gadgets and if there is a worked in divider charger. We granted the most indicates battery packs that had both a worked in lightning and smaller scale USB links — sorry USB-C clients, compact chargers haven't exactly made up for lost time yet.
While the vast majority of these items depend on a charging link to recharge the battery, a portion of these power packs have a worked in attachment to connect them ideal to a standard divider attachment. These are by a long shot our top choice, as they make it difficult to overlook the charging link and limit the measure of stuff that you need to bear with you.
Moreover, we additionally granted focuses dependent on the included guarantee and if there is a worked in spotlight.
While we at first didn't know about the helpfulness of this component, we were entirely astounded about how convenient it ended up being.
Revive Time
For the last 10% of the aggregate score, we planned and scored to what extent it took to revive each pack. This was a generally straightforward arrangement of tests, where we planned to what extent it took each pack to charge when it was completely drained, utilizing a Samsung USB control block and the included link or the inherent divider charger if the pack had that.
End
On the off chance that you are keen on precisely how a particular model did or need to see which compact battery pack earned the best spot, look at our entire Portable Charger survey. Then again, on the off chance that you are searching for a more intensive clarification of how these items function, the advantages and disadvantages of various models, and what to search for when attempting to choose another model, head on over to our Buying Advice manage for significantly more foundation data!

Stage 1: How Big a Battery Do You Need?
The main thing you will see when contrasting diverse convenient chargers is the distinctive limits accessible. This is normally estimated in milliamp-hours, with the "milli-" prefix making this unit 1/1000 of an amp-hour. Incidentally, most battery packs are really a few thousand milliamp-hours, implying that a 10,000 mAh or 20,000 mAh pack could be composed significantly more briefly as 10 Ah or 20 Ah. In any case, that is the standard that pretty much every producer has picked for buyer gadgets, so we will stay with that.
Basically, the milliamp-hour limit alludes to the aggregate sum of electrical vitality that every battery pack can store. In particular, it states what number of milliamps of electric flow every battery pack can accommodate 60 minutes. To utilize an auto relationship, the milliamp-hour rating is much the same as how extensive of a gas tank the battery has.
Since you have a smart thought what the limit rating alludes to, it's an ideal opportunity to figure out which measure battery is the best fit for you. While a bigger battery can clearly charge a larger number of gadgets a greater number of times than a littler battery, greater isn't really better with regards to these items. As a battery's ability expands, its physical volume, weight, and cost more often than not go with the same pattern.
In the event that you are simply searching for a battery to finish off your cell phone by the day's end or convey as a reinforcement on the off chance that you neglect to charge your telephone one day, we would prescribe a 5,000 to 10,000 mAh item. These ought to have the capacity to charge a solitary cell phone 1-3 times and are generally little enough to be conveyed in a pocket or tote with no critical uneasiness or weight gain. These littler power packs additionally revive essentially quicker than their bigger brethren.
On the off chance that you more often than not convey two gadgets and need to guarantee that you can charge them two totally, you might need to scrutinize to a 10,000 to 15,000 mAh pack. You can most likely escape with a 5,000 mAh pack in the event that you are charging two littler gadgets, similar to a work and individual telephone or a cell phone and smartwatch/wellness tracker, however you unquestionably need to scrutinize in the event that you are charging a bigger gadget, similar to a tablet. Presently, it's solitary important to survey on the off chance that you routinely need to charge both of your gadgets or can't chance having it is possible that one kick the bucket on you. On the other hand, battery packs this size can as a rule charge a solitary standard cell phone 3-5 times, so this size may be a decent choice for short outings where you probably won't approach an outlet, for example, an end of the week outdoors or exploring trip, or in the event that you would prefer not to need to energize your battery pack each time you utilize it. You can likely escape with charging packs of this size once per week or each couple of days, on the off chance that you are just utilizing it to charge or finish off a solitary telephone.
In any case, these bigger packs — particularly the 10,000 mAh models — can be more unwieldy to convey and are generally much more qualified for a tote, knapsack, or PC case, instead of a pocket.
At last, you should take a gander at the 15,000 mAh and up models in the event that you have to charge a huge amount of gadgets every day or on the off chance that you are anticipating going an all-encompassing timeframe without access to a charger. Seven days in length exploring or other boondocks trip rings a bell, where you need to charge your telephone or camera every day. Essentially, any multi-day circumstance where you have to routinely charge a gadget and won't have any entrance to control is a decent possibility for the biggest convenient power packs.
Being Prepared
The biggest power packs (20,000 mAh+) are an incredible thing to add to a first aid pack for power blackouts or even other catastrophic events. You ought to intermittently check the battery and finish it off at regular intervals, as they can gradually exhaust their charge when put away for significant lots of time.
In any case, it is imperative to hold up under at the top of the priority list on the off chance that you are getting one of these beast packs to charge various gadgets, you should remember that you might be constrained by the quantity of USB yield ports on the gadget — utilizing a USB-splitter isn't generally prescribed — and the most extreme conceivable yield of the battery pack, which drives us to our next theme.
Stage 2: How Much Current?
Since you have selected which estimate battery pack you require, it's imperative to check what the most extreme release rate of the battery is and if the rating is shared between all the USB ports or for every individual one. Proceeding with our auto similarity, if the milliamp-hour rating is proportional to the extent of the gas tank, the release current would be generally keeping pace with how quick you drive or — all the more nearly — how rapidly you are pulling gas from the tank. The quicker you pull the gas, the speedier the tank will drain, with a similar remaining constant for battery packs.
This is essential to check for the battery pack that you mean to purchase, as it is genuinely simple to surpass the most extreme rating on a few packs, especially in the event that you are anticipating charging numerous gadgets at the same time. The most up to date cell phones can attract up to 2.4 amps when they are charging at their quickest speed, with bigger gadgets drawing considerably more power. A battery pack that has a release rating not exactly the most extreme power draw of your battery pack may at present charge it, however it will take essentially more. For instance, a battery pack evaluated for 1 amp discharger will likely take something like twice the length you are utilized to charge your cell phone and will charge bigger tablets considerably slower, if by any stretch of the imagination. A pack appraised for 2.4 amps will for the most part charge your telephone at a practically identical speed to it being connected to an ordinary divider attachment with a brilliant divider block.
Notwithstanding, on the off chance that you plug two cell phones into a battery pack that is appraised for 2.4 amp release that is shared among the ports, the two telephones will charge much slower than run of the mill and two tablets will charge infuriatingly gradually.
On the off chance that you are anticipating charging various gadgets, you need to search for a pack evaluated for at any rate 3.4 shared amps for two telephones and knock it up to 4.8-5 amps of shared release in the event that you need to attach different tablets or similarly vast electronic gadgets.
Once in a while, the biggest power banks will have a settled sum for every port, for example, two 2.4 amp USB ports for tablets and a 1.2 amp port for littler gadgets, so you should ensure your planned utilize lines up with that. For instance, this setup wouldn't be extraordinary for charging three high power gadgets however would be incredible for charging a cell phone, tablet, and wellness tracker.
Stage 3: Any Extra Convenient Features?
Since you have made sense of what the electrical attributes of your ideal versatile charger ought to be, it's an ideal opportunity to consider any extra highlights that can enable you to limit your decision between your last competitors.
The three highlights that we observed to be the most valuable are worked in gadget links, worked in charging plug, and an implicit spotlight.
On the off chance that you realize that you are continually going to charge a specific gadget or gadgets that share a similar kind of charging association, it pays to get a convenient battery that has a worked in link.
For instance, on the off chance that you are continually charging your iPhone and iPad, getting a power pack with a lightning link incorporated appropriate with it implies that you can't ever overlook the link and a coordinated link for the most part makes for a substantially more minimal in general bundle, contrasted with conveying one independently. Furthermore, this battery packs typically likewise have a USB port, so you aren't completely secured into the assembled charging association in the event that you have to charge an alternate gadget.
Similar remains constant for battery packs that have a standard divider plug worked in for energizing.
This is our most loved comfort include, as it blocks the requirement for conveying a different charging link and a USB divider connector. It makes them substantially more helpful to convey and keeps you from overlooking either the link or the divider connector.
At last, a portion of these battery packs have a worked in spotlight. This isn't exactly as helpful with a portion of the littler packs, however it is a pleasant component on the bigger packs which are typically utilized when you are in the boondocks or other remote spots. We didn't discover it as valuable with the littler, consistently convey packs, as we normally wanted to utilize the electric lamp on our telephones.
End
Ideally, this guide has given you a superior comprehension of the intricate details of these items and allowed all of you the instruments you have to select the ideal convenient power pack. On the off chance that you are searching for more data on how we positioned and scored these items, you can look at our How We Test article for a definite portrayal of our testing conventions or investigate our Portable Charger Review to see which ones we thought are the most perfect out there!
How We Tested Portable Chargers
Considering how we positioned and scored convenient chargers? Initially, we did tons and huge amounts of research and investigation, at that point picked the most encouraging items to test straight on. We charged a wide range of things with these items — everything from cell phones to smartwatches. Moreover, we additionally estimated the genuine yield and pushed these items as far as possible utilizing an advanced multimeter and a sham resistive electrical load, and also timing to what extent every one took to energize. Beside the electrical parts of these batteries, we likewise evaluated and made a decision about precisely how versatile these compact USB chargers are and how much less demanding and more helpful they can make your regular day to day existence. We stepped through the majority of the exams we did and assembled them into four weighted rating measurements, with our correct methods plot underneath.
Conveyability
Justifying 40% of the aggregate score for every compact charger, compactness is a crucial quality of these items, as the name would propose. For this test, we gauged the aggregate volume and the heaviness of every battery pack, at that point scored them as needs be.
While there is a slight connection between's battery pack size and execution in these two tests, we found that a few packs have uncontrollably extraordinary sizes and weights, regardless of having the equivalent recorded limit.
We additionally evaluated and scored that it is so agreeable to bear these items in your pocket. We had analyzers stroll around and sit with every battery pack in a front and back pocket on a couple of pants, looking at how every battery pack felt next to each other and taking note of if there were an especially uneasy weight focuses. We chose a couple of coolly fitted pants for this test, as we felt they were a decent center ground, with other baggier attire effectively fitting the majority of the power packs without issue and anything more tightly basically blocks you from conveying the vast majority of these items in your pockets.
Limit
For our ability metric, which establishes 30% of the last score for every compact battery pack, we directed two separate tests. In the first place, we needed to test the maker claims for every battery pack. The majority of the items in this audit had a type of case of each pack having the capacity to charge certain telephones a specific measure of time.
We utilized a Samsung Galaxy S8 as a test telephone, charging it the greatest number of times as we could off of each completely charged battery pack and scored every item dependent on in the event that it surpassed or missed the mark concerning its showcasing claims.
For our second test, we took a gander at what the genuine limit of each pack is, scoring dependent on what the asserted limit of every convenient charger is. We quantified the limit by completely charging every item, at that point releasing into a fake load through a computerized multimeter. This fake load given us a chance to set the current attract to the greatest that each pack could deal with, with the meter timing to what extent the pack had been releasing for — and helpfully ascertaining the aggregate vitality released for us appropriate on the screen.
On the off chance that this sounds somewhat specialized, it knows a smidgen about how these items are appraised. These versatile power packs are appraised in some number of milliamp-hours, which for those that are new, is a proportion of aggregate vitality and alludes to how much power each pack can hotspot for 60 minutes. You can think about an amp, or ampere to utilize its full name, as the rate at which power is conveyed, so increasing that by some measure of time gives you the aggregate electrical vitality conveyed. An amp is a significant huge measure of electrical flow, so for most buyer items, we typically connect the "Milli-" prefix, signifying 1/1000 of an amp. For instance, a 10,000 mAh module is hypothetically evaluated to have the capacity to release at a rate of 10,000 milliamps (or 10 amps) for 60 minutes, or at a rate of 20,000 milliamps (or 20 amps) for 30 minutes. For reference, most present day tablets charge at a rate of 2.1-2.4 amps, so a 10,000 mAh pack ought to have the capacity to charge one of these gadgets for very nearly five hours. Practically speaking, we observed this to be a long way from the case.
Included Convenience
Next, we took a gander at how advantageous every convenient battery pack is to utilize, basically centered around if there are any extra highlights that made them especially simple to utilize. Altogether, this gathering of tests is in charge of 20% of the aggregate score.
In the first place, we granted focuses dependent on what number of gadgets you can charge at the same time on every battery pack. We likewise considered the greatest yield of every charger, granting the most indicates models that could deal with charging different eager for power gadgets immediately, similar to tablets or the biggest cell phones.
We at that point took a gander at any inherent highlights, to be specific worked in charging links for different gadgets and if there is a worked in divider charger. We granted the most indicates battery packs that had both a worked in lightning and smaller scale USB links — sorry USB-C clients, compact chargers haven't exactly made up for lost time yet.
While the vast majority of these items depend on a charging link to recharge the battery, a portion of these power packs have a worked in attachment to connect them ideal to a standard divider attachment. These are by a long shot our top choice, as they make it difficult to overlook the charging link and limit the measure of stuff that you need to bear with you.
Moreover, we additionally granted focuses dependent on the included guarantee and if there is a worked in spotlight.
While we at first didn't know about the helpfulness of this component, we were entirely astounded about how convenient it ended up being.
Revive Time
For the last 10% of the aggregate score, we planned and scored to what extent it took to revive each pack. This was a generally straightforward arrangement of tests, where we planned to what extent it took each pack to charge when it was completely drained, utilizing a Samsung USB control block and the included link or the inherent divider charger if the pack had that.
End
