Just arrived today, ordered a week or so ago.
Mine was clearly a return, but in very good shape, all docs, cables, etc. Seems to take and hold a charge well. Keep in mind, this is a big girl, its the size of a mini tablet. Takes some time to charge at 2.1 amps, then again it should power a larger unit for quite some time.
TWO (charge) USB outputs, one (input) - test button with “fuel gauge”.
