Pros: USB Port delivers 5V and i tested it up to 3A! Amazing! The output port is 5.5 x 2.1 mm and is pre set to 12V. Can be adjusted within the box up to 24V. I use the 12V for my little chinese power amp (last photo) which works great! Cons: Input is 3.5 x 1.35 mm and you must use a stable 8.4V power supply to recharge the box. There is no charging circuit in the box so if you exceed 8.4V you will blow up your batteries. There are also no lamps glowing when in charging mode!
