Review: 4-cell/6-cell 18650 USB Mobile Power Banks #1

Review of two different USB mobile power banks – white 4-cell with 3-digit 7-segment LED display and black 6-cell with 5 LED display. Both have 2x USB sockets, a 1A socket and a 2A socket. Both have a 4mm multi voltage output jack. The white unit can provide between 5v and 13v in steps of 0.5v and the black unit supplies 3.7v, 5v, 9v and 12v.
