Product review: Lomui 5200mAh External Battery Power Pack

The Lomui 5200mAh charger is one of the smallest batteries of this capacity I have seen. It is easily fits in my purse or funny pack. With capacity 5200mAh it is not intended for a real heavy use, but it is good for portable emergency power. The battery is only 3.5"x1.75"x0.75" and its weight is only 4.10 ounces. It has one charging port (1A).

I noticed that the Amazon description has a couple of errors:
(1) this power pack has no built-in flashlight mentioned in the title
(2) this package came without a small bag mentioned in the description

Neither thing is a big deal for me but for completeness of the review I wanted to include this information.

The charging status is indicated by a tiny LED indicator. It is blue when a mobile device is being, and red when the battery is being charged. There is no indication of how much charge is left in the battery.

This charger worked with both my Android Nexus phone and iPad Mini tablet. iPad Mini needs more than 1A for optimal charging speed so with 1A port below optimal speed of charging is an expected outcome.

To tell how various battery packs perform I measure their performance with a current monitor. I use Samsung Nexus phone and iPad Mini for testing to give me a Android and an Apple mobile devices. I test all my chargers using the same charging cables and starting all tests at same charge level of the phone to account for non-linear charging. This allows me to compare different batteries to each other so I can rate the battery keeping everything else constant.

Samsung Nexus phone:
~~~~~~~~~~~~~~~~~~~
Lomui: ___ 0.90/5.03V (somewhat below optimal)
(for comparison the best charging monitor result for this phone is 1.00A/5V)

iPad Mini tablet:
~~~~~~~~~~~~~~~~~~~
Lomui:___ 0.93/5.02V (below optimal)
(for comparison the best charging monitor result for this tablet is 1.70A/5V)

I like the shape and size of this battery. It comes in very attractive colors. It is good for emergency power on the go.
