A look at a red pepper USB power bank.

A look inside a rather pleasing red-pepper shaped USB power bank. For some reason they have ground the number off the chip, which is strange given how common the power bank chips are.
I've not had a chance to do a full charge discharge test on this unit to see the upper and lower cell voltage limits, but I would guess that will be the usual thresholds.
As shown in the last part of the video, it makes a very ergonomic flashlight when used with the power bank flashlight adaptors.
