Buyer’s guide: how to buy right power bank

Power banks, also known as external batteries, have been widely used among people especially in this digital era where digital and smart devices are flooded in our daily life. This guide on how to buy the right power bank is useful for those who do not know much about power bank technology, brands or pricing. Before actually buying a power bank, you should know the capacity of your digital device or you may find it out from the device manual. To put in a nutshell, you should buy power bank with capacity larger than the one listed on your digital device. Then you just need to opt the highest capacity that your budget allows you.

And do remember to check the “current draw”. Most of older device may require only 1A for charging; however the newer digital devices mostly require 2.1A for charging. To be safe, you’d better buy power banks with both 1A and 2.1A USB ports. One thing you should not ignore is that there are mainly 2 types of battery cells: Lithium-ion or Lithium-polymer, the first one is cheaper, but the second expensive one provides twice as much charge density as the first one. Most importantly, you should make sure that your power banks are quality ones produced by reputed factory. Often the cheap ones do not only list the correct current draw, but also easily explode due to over-charging. The quality ones, of course they are more expensive, but they have over voltage protection, over charge protection and over-temperature protection.
