  1. When It {Comes to|Concerns|Pertains To} External Battery {Packs|Loads}, {Capacity|Capability} Isn't {Everything|Whatever}
  2. {Smartphones|Mobile phones|Smart devices} and tablets {these days|nowadays} are {effectively|efficiently|successfully} pocket {computers|computer systems}. {But|However} being multi-talented comes at {a cost|an expense} of {considerable|significant|substantial} battery drain. {Until|Up until|Till} the next battery {breakthrough|advancement|development}, {most people|many people|the majority of people} today {opt|choose|decide} to {carry|bring} an external battery pack (a.k.a. power bank) with them. Here are some {tips|suggestions|ideas|pointers} on how to {go about|tackle|set about} {choosing|selecting|picking} one; or put another {way|method}, {reasons why|reasons|reasons that} some battery packs are more {expensive|costly|pricey} than others.
  4. 1. {Capacity|Capability} vs. {Portability|Mobility}
  5. The {main|primary} {spec|specification} to {look out|watch out|keep an eye out} for in a portable battery pack is {capacity|capability}, which is {measured|determined} in milliampere-hour (mAh). The {capacity|capability} of your {device|gadget}'s battery is {also|likewise} {measured|determined} in mAh, so loosely speaking, if your phone has a 2,000 mAh battery, a 2,000 mAh battery pack {is able to|has the ability to} {recharge|charge} it {fully|completely|totally} {once|when|as soon as}. {However|Nevertheless}, {because|since|due to the fact that} of power lost due to voltage conversion and circuit resistance ({remember|keep in mind}, the {rated|ranked} {capacity|capability} is {usually|typically|normally|generally} for 3.7 V, {but|however} {during|throughout} charging, the output is at 5V), and {sometimes|in some cases|often}, the quality of the charging {cable|cable television}, this is {rarely|seldom|hardly ever} the case in {reality|truth}. While you can get one with {a higher|a greater} {capacity|capability} (there are battery packs which {go up|increase} to 20,000 mAh) so that it{'s able to| has the ability to} {recharge|charge} {a device|a gadget} {multiple|several|numerous} times over, {keep in mind|bear in mind|remember} that this {usually|typically|normally|generally} {also|likewise} {means|implies|indicates|suggests} that it's {bigger|larger}, {heavier|much heavier}, and {pricier|more expensive|costlier}.
  7. 2. Your {Mobile Device|Mobile phone}'s Input Current
  8. {Most|Many|A lot of|The majority of} smartphone-oriented battery {packs|loads} output at {most|many|a lot of|the majority of} 1A (at 5V) over the USB port. While this works fine for {most people|many people|the majority of people}, some {may|might} {notice|discover|observe|see} that their {smartphone|mobile phone|smart device} now takes a longer time to {recharge|charge} as compared to when a wall {charger|battery charger} is {used|utilized}. This is {especially|particularly|specifically} {true|real} if the phone {is able to|has the ability to} accept {a higher|a greater} {current|present|existing}. {Many|Numerous|Lots of} {recent|current} Android {smartphones|mobile phones|smart devices} have a 1.5 A charging {interface|user interface}, and those which support Qualcomm's Quick Charge 2.0 {standard|basic} (e.g. LG G2) can draw as much as 2A. So, {manage|handle} your expectations.
  10. {Most|Many|A lot of|The majority of} tablets {require|need} {at least|a minimum of} 1A to charge too, with some {drawing up|preparing} to 2.5 A. Take the Apple iPad Air {for example|for instance}, which {comes with|includes|features} a 12W USB wall adapter that {provides|offers|supplies} 2.4 A. If you were to plug the iPad Air to a battery pack's 1A USB port, it'll either not charge or charge {super|very|incredibly|extremely} {slowly|gradually}. So if you're {looking to|wanting to|seeking to|aiming to} charge a tablet, our {advice|guidance|recommendations|suggestions} is to {buy|purchase} a battery pack that{'s capable of| can} outputting {higher|greater} than 1A ({at least|a minimum of} 1.5 A if you{'ve| have actually} an Android tablet, and 2.1 A if you{'ve| have actually} an iPad). {Lastly|Finally|Last but not least}, there's no {harm|damage} {using|utilizing} a higher-powered port on {a smartphone|a mobile phone|a smart device}, as the {device|gadget} {only|just} draws what is {required|needed}. In {fact|truth|reality}, it {may|might} even charge {faster|quicker|much faster} if it{'s able to| has the ability to} draw more.
  12. 3. The Battery {Pack|Load}'s Input Current
  13. It's {easy|simple} to {persuade|convince|encourage} yourself to {buy|purchase} a large-capacity battery pack. {But|However} one tends to forget that the {higher|greater} the {capacity|capability}, the longer it {takes to|requires to} {recharge|charge}. In {fact|truth|reality}, {most people|many people|the majority of people} {we know|we understand} who have 15,000 mAh battery packs leave them to charge {overnight|over night}. Another {factor|element|aspect} that {affects|impacts} {how long|for how long|the length of time} it {takes to|requires to} top up the charge is the battery pack's input current. {Most|Many|A lot of|The majority of} battery {packs|loads} accept {between|in between} 0.8 A and 1.5 A, with the {higher|greater} currents {typically|generally|usually|normally} {found|discovered} on the {higher|greater} {capacity|capability} ones. If you {come across|encounter|discover|stumble upon} {two|2} {seemingly|relatively|apparently} identically-spec' ed battery packs and both cost the {same|exact same|very same}, this little {detail|information} {could|might} be the tiebreaker.
  15. Some battery {packs|loads} {allow|enable|permit} themselves to be charged while they're charging other {devices|gadgets}. {However|Nevertheless}, we {don't|do not} {recommend|suggest|advise} it {because|since|due to the fact that} {constant|continuous|consistent} pass-through charging {may|might} {affect|impact} the battery's {lifespan|life expectancy|life-span}.
  17. 4. {Number of|Variety of} Ports
  18. {Many|Numerous|Lots of} {recent|current} battery {packs|loads} {come with|included|featured} {a built-in|an integrated} USB {cable|cable television} that {wraps around|twists around} the case so that you {don't|do not} {need|require} to {worry about|stress over|fret about} leaving the USB {cable|cable television} {at home|in your home|in the house}. To {cater to|accommodate|deal with} iOS users, {some of|a few of} them {come with|include|feature} {a built-in|an integrated} Lightning {cable|cable television} {instead|rather}. These Lightning connector-compatible battery {packs|loads} tend to cost more than their USB {counterparts|equivalents} {because|since|due to the fact that} of the MFi ({Made For|Produced} iPhone/iPod/iPad) licensing and {certification|accreditation} program {fees|charges|costs} the {manufacturers|producers|makers} {have to|need to} pay.
  20. {Higher|Greater} {capacity|capability} battery packs {also|likewise} {usually|typically|normally|generally} {come with|included|featured} more than one USB charging ports. Naturally, more ports cost more {money|cash|loan}, and the {number of|variety of} ports you {should|ought to|must|need to} {go for|opt for|choose} {depends on|depends upon} {how many|the number of} {devices|gadgets} you {carry|bring}. The {biggest|most significant|greatest} {advantage|benefit} of {additional|extra} ports is that you can charge more {devices|gadgets} at the {same|exact same|very same} time. The {tip|suggestion|idea|pointer} here is to {find out|discover|learn} the {total|overall} output current of the battery pack when more than one ports are {used|utilized}. {For example|For instance}, a battery pack with {two|2} 2A/5V ports {may|might} output the 2A when {only|just} one port is {used|utilized}. When both ports are {connected|linked}, the {total|overall} output {may|might} be {limited|restricted} to 3A, with each port getting 1.5 A. There are {of course|obviously|naturally} others that have {a total|an overall} output of 4A (so both {devices|gadgets} {are able to|have the ability to} charge as {fast|quick|quickly} as they can), {but|however} as you {might|may} {expect|anticipate}, they {usually|typically|normally|generally} come at a premium.
  22. 5. Quality vs. {Price|Cost|Rate}
  23. Batteries can {explode|blow up|take off}, and the one {measure|step|procedure} we can {take to|require to} ({hopefully|ideally}) {prevent|avoid} this is to {buy from|purchase from} name {brands|brand names} or {reputable|reliable|trusted|respectable|credible|trustworthy} {vendors|suppliers}. To {allay|ease} such {fears|worries}, some battery pack makers will {tell|inform} you ({usually|typically|normally|generally} on the {packaging|product packaging}) where they source their batteries from. So while that $10 brand-less battery pack {sounds like|seems like} {a great deal|a good deal|a lot} compared to {a branded|a top quality} one that costs {three|3} times as much, we would {think twice about|reconsider|hesitate about} it, {because|since|due to the fact that} it's {often|frequently|typically} {impossible|difficult} to {know|understand} if it cuts any corners with the {short|brief} circuit, over charging, and {temperature|temperature level} {protection|security|defense} {mechanisms|systems} in order to {achieve|accomplish|attain} the low {price|cost|rate}.
  25. {Lastly|Finally|Last but not least}, when something sounds too {good|great|excellent} to be {true|real}, it {usually|typically|normally|generally} is. If you {chance upon|come across|encounter|bump into|discover} a 6,000 mAh battery pack that's a quarter the size of other battery {packs|loads} with the {same|exact same|very same} {capacity|capability}, and there's no {mention|reference} on how it {achieves|accomplishes|attains} this {feat|accomplishment|task}, the {capacity|capability} claim is {likely|most likely} to be over {exaggerated|overstated}.
