What a great Powerbank.
It would appear that Ravpower have thought of everything, in the well packaged box, not only do you get the power bank, you also get different charging tips, a charging lead, a powerout lead and a nice pull string bag to keep all the goodies in as well as the simple manual.
The Black unit looks really good, it has a nice shiny case and is sure to draw attention.
The unit weighs about 226 gram, and is pocket sized.
There is a simple power switch on the top of the unit, next to a bank of 4 Blue Led's, to indicate charge, the size of the LED's increase from minimum to maximum, and only illuminate for a few seconds to indicate state of charge, 25,50,75 & 100%
The powerbank has two USB ports, 1 is capable of delivering 2.1 amp and the other 1 amp, testing the outputs I got a healthy 5.26 Volts on the 2.1 amp port and 5.20 on the 1 amp.
I thought that the unit did not have a power off switch, it doesn't but what is does is automatically switch off once it detects that no current is being drawn by the connected device, naturally this occurs if 1) there is nothing connected or 2) the connected device is fully charged a nice feature which prevents the battery from going flat.
I was able to charge my Ipad, Phone, Tablet with no problems with capacity to spare.
Charging time for the actual power bank depends on how must charge is left in it and the charger used to charge the unit, I used my Ravpower4 port charger which had more than enough power to charge the unit.
What can I criticise, well not a lot really, the shiny black case is a fingerprint magnet.
I can see this being of use for the constant traveller, much like myself, and would not be out of place in an executive boardroom.
