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.

2. Number of USB output Ports
Number of output port of a power 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 in the power bank, you can feel tension
free about getting drained off completely in all
of your mobile devices.

3. Input Current Ratings

• Have you ever thought about what 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.

4. Types of Battery Cells
There exists two major kind of portable power
bank battery cells, namely Li-poly and Li-ion.
Both having their respective advantages and
disadvantages. Li-poly mainly becomes more sleek
and high priced, where Li-ion are bulkier and
less expensive.

5. Pass through charging

• 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 though seems obvious, lacks
  in most of the power banks and being a useful
  one, one should be enquiring before zeroing on
  one power bank, whether the portable charger
  supports pass through charging.
