The increased fame of Android, iPhones, and iPads has resulted in a new interest—high-capacity power banks. This is not surprising however. As smartphones and other gadgets become more advanced and consume more power, they have this unfortunate tendency to have a battery life that is low. How many times have you used your smartphone or gadget to take photos or video clips, share them in Facebook, Instagram, or Twitter, or when you check your email or play games, when suddenly, your phone or gadget dies out?

To keep your gadget or phone on for a little bit longer time, power banks are mainly created to help you have fun using your gadgets without worrying over the life of their batteries.

But how do you select which one is the best for your smartphone or gadget? Although there are many brands of power banks in the market nowadays, choosing the best one is not a walk in the park.

Buying a power bank will ultimately has to depend on your usage needs. For example, if you do not have too many devices when you go out or travel, then a small power bank that has a low capacity may be enough to charge your phone. However, if you have several gadgets and you use them all the time, you may need a high-capacity power bank.

Check the capacity (which is measured in milli Ampere Hour or mAH) of a power bank before you buy. It is almost impossible to calculate how many times a power bank product can charge your gadget, but basically, the rule of thumb is that the more mAH rating a power bank has, the more capacity it has. So for example, if your gadget has a 1500 mAH battery, ideally, a power bank with a capacity of 1500 mAH can fully charge it once. Of course, a power bank that has a larger capacity and output voltage than your gadget, then ideally you may get several charges.

Also, make sure that the power bank can charge your gadget’s battery (meaning the power bank’s output voltage matches with the gadget you own). Otherwise, it would not work.

Some power banks offer higher mAH (such as 8400 or 11200) for those who have big charging needs. Some charges can charge various devices from different companies, including laptops, tablets, iPad, and mobile phones from Samsung, Apple, HTC, among others.

When selecting power banks, make sure you buy one that it is not used. Used power banks will be a huge waste of money because their life span is not that much. The life span of a power bank can be reduced drastically if the product is kept for long periods of time in adverse environmental conditions. Do not also buy a power bank that is using refurbished batteries.

You may also want to look for a power bank that has a built-in USB charging capacity. Older power bank models do not have this feature.

    David, thanks for the article, but it simply looks like a catalog. I got here because of my query on why some banks charge certain devices and some do not. My beefy 20,000 is extremely finicky. Where as a small 2,300 charges everything, my 10″ Galaxy tablets and S5. (You do know there are 2 phones beyond the S3, right?)

    I.e., it’s more than just the specs.
