As the usage of smartphone has increased rapidly, investing on power bank has become a necessity. Though smartphones come with high-performance battery, due to increased internet usage (thanks to JIO) for heavy browsing or live chatting, the battery seems to drain quickly.
So, if you are a person who travel long distance regularly or need your mobile to keep going on for a longer period of time then a power bank can be helpful.
While selecting a power bank, the main factor to consider is battery capacity which usually depends on your power backup requirements. A 10000mAh battery capacity power bank can charge your phone 2 – 3 times in a day while 20000mAH can charge 5 times per day. Apart from that, you have to consider No.of USB ports for multiple device charging, weight and portability for pocket friendliness and others.

If you want to power back up for small devices like bands, smart watches and others then 10000 – 13000 mAH is more than enough. The same is also good enough for mobile or smart phones as well. Because most of the phones have 3000 – 4000 mAH of battery capacity, you can easily charge 3 – 4 times.
