Which is the best power bank availabe in the market for the high end smartphones?

Question

I have two questions here:
1. Which is the best power bank available?
2. What factors do you consider while buying a power bank? (if possible, share some useful links on this)

Answer 1

1, Some well-known brands to me are RavPower, Powergen, Mophie and Mipow.

2, My priority considering getting a power bank is its capacity, size, and its value. I have 2 battery chargers, one for 3000mAh and one for 14000mAh. The 3000mAh is a pretty handy one so I could carry it out for work all the time. The 14000mAh is a juicy one and it has a 2.1A output which could charge my tab as well. So I would take this one when I am out for a long journey or away from home for a while.



You could take a look at the 2 chargers I've used here:

Answer 2

Hey there,



1. Some of the better brands out there are Pisen, Powerocks, Yoobao, etc.

2. Generic/brandless power bank sometimes have fake capacity. Meaning they may be labelled 10,000mAh, but the actual capacity may just be 7000mAh.



Best to go for branded ones as listed above to ensure real capacity are labelled.

Branded ones typically have better safety feature and comes with higher quality.



Another factor is power bank capacity. 10000mAh power bank can charge a 2500mAh battery for approx 3-4 times.



Calculating heat loss, it's not possible for 10000mAh power bank to fully charge 2500mAh battery 4 times.

So it would be 3-4 times, approx.

You can google power banks at ebay , amazon ,aliexpress , then there are so many for your selection . But now you should decide what capacity you need for your phone . As usual , brand power bank's quality is good ,like Xiaomi brand.
