2 of 5 Nice battery, bright light, chintzy-a** power modu November 23, 2020
Reviewer: Anonymous Person  
This kit is only useful in a serious pinch.  Neither accessory takes advantage of the battery's pricey raison d'etre, high continuous discharge.

The lantern is too bright to read by comfortably. It would be good for working e.g. under a vehicle hood--as long as there's somewhere completely dry and flat to set it.

The charger can't handle more than the slightest jostle without breaking connection. It has to be completely disconnected and reconnected to reset and resume charging or discharging. Useless on the fly in a pocket or bag. Its only input is usb micro. And it can only deliver 10W in either direction.

I admit I was taken in by the seeming minimalism of this kit. But in hindsight would much rather pay a bit more for a tube enclosure that takes advantage of both sets of terminals to drive beefier charge circuitry.

5 of 5 Very Practical November 8, 2020
Reviewer: Odell Chinen from Aiea, HI United Satates  

My wife and I found the MPB21 to be a great addition to our go bag.  The duration of light is excellent.  Very good feature that this MPB21 can also be a power bank.
