1. Capacity of the Portable chargers
Capacity of the portable power bank says about the deliverable amount of power that a
power bank can retain rather sustain within itself. Most of the best power banks tend to
have capacity around 10000 mAh. But we should be keeping it in mind a 10000 mAh
power bank can not reproduce whole of its power while charging due to conversion loss.
Thus the delivered outcome is always less than 10000 mAh. Precisely the average efficiency
of power banks is found around 75%.

bank signifies the ability of a power
bank to charge several power banks
at one go. This feature is very helpful
for the case if someone has more
than one devices, as we generally
have like a smartphone and a tablet
or two smartphones. With this feature

time would the power bank take to
get fully charged? It highly depends
on the input current rating of the
portable charger, as the higher the
rating, the less time it would take to
get charged. Generally there comes
two types of rating namely 1A and 2.1
A at 5V. 2.1 power banks would
charge themselves nearly twice as fast
as that of 1 A ones.

 Pass through charging makes a power bank enable to power up the devices that are
connected to it when the portable charger is getting charged by itself. This feature

should be enquiring before zeroing on one power bank, whether the portable charger
