Power Bank Buyer’s Guide
We just went over some of the best power banks that you can buy this year.However, sometimes all these terminologies and numbers can be confusing. Especially if you are new to the world of external battery packs or just are not very “tech-savvy”.
No worries, we got you covered! We will walk you through all the important concepts you need to know and simplify them so you can make an educated decision on what is the best power bank for your needs.
Alright let’s being.
Basics of Power Bank
What exactly is inside a power bank, anyway? Mostly it is composed of a lithium battery that has been connected to some advanced circuitboard and put inside an external casing. Well, that’s over simplifying things a bit but you get the idea. Over the past couple years, as the amount of devices we carry around have increased, the markets have been flooded with many external batteries.
What is the capacity?
Most batteries inside our devices are rated in mAh or milliAmpere hours. So if you have a device that holds 10,000 mAh in the battery, this doesn’t mean a 10,000 mAh power bank will fully charge your device.
Most manufacturers rate these external batteries at the voltage of the battery, but that number has been hiked up a little in order to charge your device. In addition to that, there is also some power lost as heat in the conversion process. Surrounding ambient temperatures will also have an effect.
So, as a general rule, subtract 15% from the quoted figure to get a more accurate estimate of how many charges you would get from your new power bank.
The speed at which a power bank is capable of charging devices is an important consideration point. Most of the above featured power banks now come with intelligent voltage systems that will provide power as fast as the device asks for it, as long as it is within the capacity of the external battery.
Also, you will notice that power banks take considerably long time to charge themselves. So, unless you batter comes with one, it is a good idea to invest in a good 2A+ wall charger. These allow for faster charging. Refer to the manufacturer’s instructions to find out what is the best rating for charging the power bank.
Lastly, you want to see how many charging cycles the battery is rated for. Usually higher the charging cycles of an external battery, higher the price. So most high-quality power banks are on the higher end of the pricing spectrum.
Protecting your investment
Now-a-days, it is very rare to find power banks without any self-protection technology. At the least having over-charging protection should be a standard in your consideration. A lithium batter on fire is not a situation you want to find yourself in.
Please also take care to not handle your batteries roughly, drop them, immerse in water or expose to extreme temperatures. This may lead to personal injury but also severe damage to your power bank.
Size does matter
Sometimes you may find you power banks with identical mAh rating, however varying greatly in size. This may be due to different battery density and/or the number of cells in them. Smaller batteries tend to have less charge but idea for people on the go e.g. this one is as small as a lipstick.
What is passthrough capability?
A lot of the new power banks will feature something called, a passthrough ability. All this really means that the power bank itself can be charging other devices while it is charging itself. So in essence passing the charge through itself to the device as it charges. The biggest advantage to this is that it reduces the amount of cables you have to carry around.
This covers most important concepts you need to know before buying the power bank. These are mostly common among all power banks you will see in one way or other. Then there are other things like solar charging, water resistant, rugged body, etc. But that’s all extra depending on your needs and lifestyle.
