Product review: Kenruipu Power Bank 24000mAh

♦ size: 6.5" x 3.25" x 0.75"
♦ weight: 15.7 oz
♦ number of out ports: 4
♦ capacity: 24000 mAh
♦ number of in ports: 2 (mini USB and lightening)
♦ charge indicator: digital display
♦ flashlight: yes
♦ pass through charging: no (i.e. the battery can charge while being charged itself)
♦ cables: 1 charging cable and 1 AC cable

This battery has a large capacity (24000 mAh) and four ports.  This capacity and a large number of ports works well for traveling.

One of the things that is important to me is how quickly the battery charges my phone. To test how well the battery performs I use the same phone, at the same level of charge to compare the current draw for each external battery I test. This corrolates to how quickly the battery is charged. This allows me to do a relative comparison of different external batteries.  The battery performed at a good rate, even though it was not the absolutely optimal I have seen.


I also tested to see if the battery supports pass-through charging (i.e. whether the battery can charge mobile devices while it is being charged). This battery does supports charge through charging. It continues to charge the phone while the battery is being charged, but does so at slower rate than when the battery is not being charged.

Finally, I check if the cable that came with the battery is a charging cable (i.e. capable of charging at full AC rate) or a data cable (charging the battery at USB rate). The cable that came with camera charges at AC rate.

The battery has a flashlight, but it is quote dim.  Never the less it could be helpful in an emergency when you need to light a small area like a keyhole.
