In this day and age we rely heavily on our smartphone; they are the “smart” hubs that we not only get our notifications on but we also use them for things like setting up an alarm, saving a memo, taking a picture and even browsing the web. Sure, it is quite convenient to do all this and more from the palm of one’s hand but the downside is that this much use of a smartphone means that the battery will deplete very quickly. This a serious problem because we have become quite reliant on these little, magical devices.
Modern smartphone have large enough batteries that can last you a day or even more if you use them moderately. But if you are a heavy mobile user then you know that you are looking for a charger at around five in the evening. Sure, that is enough battery life if you don’t need your phone till the next morning but we all know that it’s not true. So you either need to plug in your phone to top it off which means that you won’t be able to use it while it is charging or you need to buy yourself a power bank.
What exactly is a power bank?
If your phone battery were bigger it would last for longer and that is basically the principle power banks are built on. A power bank is simple a bigger battery which can be charged and, in turn, is capable of charging your smartphone. It is built by combining a couple of cells together which are capable of holding a lot more charge than your humble smartphone battery.
The capacity of a battery is usually described in milliampere hour (mAh). The more the mAh a battery can hold, the longer it will last. Similarly the more mAh a power bank has, the more times it can top off your smartphone or even your tablet.
So now you understand what a power bank is, the next question is what you need to consider when buying one. If you are interested in finding out then just take a look at the points that we have mentioned below.
How much you are willing to spend?
Power banks come in all shapes and sizes; some are small enough that they can comfortably sit in your pocket while others are bigger and heavier. The bigger ones have more capacity and therefore cost substantially more than the smaller ones. So the first thing that you need to decide is that how much you want to spend on a power bank.
If you just need enough juice to keep your device alive for a couple of hours then even a small one will do. If you are want to be able to charge your mobile several times before having to plug in the power bank itself then you will have to shed out a little more dough.
The tradeoff between portability and capacity
As a general rule, the bigger the capacity of a power bank, the heavier it is. So, you need to prioritize one thing over the other. If you have a backpack with you all day long then you can easily go for a heavier one with bigger capacity, but if you just have your coat or jacket then you need to buy one which is small enough to fit in your pocket yet powerful enough to charge your device at least once.
Power bank’s output current
Another thing that you need to consider is the output current from the power bank. If it’s low then it will take a lot of time for your phone to charge. If you just plan to charge your smartphone then the power bank should at least output 1 ampere. If it does more than that and if your smartphone can take advantage of it, it will charge even faster.
