How to choose best Power Bank

You should measure power banks on below criteria before buying power banks.

Capacity: Power bank capacity is measured in mAh (milli-Ampere-hour). Higher the mAh higher the capacity means it will charge your smartphone or tablet more number of times. Below 10,000 mAh means your portable charger (Power Bank) will charge smartphone less number of times. Moderate capacity is 10,000-15,000mAh. More than 20,000 mAh power banks are considered as high capacity and they are expensive and not more choices are available in India. We have found COOLNUT 20000mah Power Bank and Samsung Ti Power Bank available in India with 20k mAh capacity.

No. of Output USB Ports: Number of USB ports is another deciding factor. More number of ports means we can charge multiple devices at a time.

Output Current Rating: Higher rating means it can charge your device fast. Right now 2A and 1A are generally available choices in power banks. Having multiple ports which can charge at multiple current rating is better as you will charge multiple devices based on their supported current rating.

Time required to charge: Input current rating determines how fast power bank can charged back. Look for a portable power bank which charge itself fast. Generally power banks take 5-12 hours to charge depending on its capacity.

Safety Protection Features: This is the most neglected feature while power banks buying but you should consider safety over all other features. Having over voltage protection, over heat protection, over charge protection, short circuit protection features should be your first choice as it will protect you & your device from any damage.
