This Breett powerbank is a no frills highish capacity powerbank delivering 10,000 mAh and it charges devices via it's two USB outlets at 2.1 Amps or 1 Amp or both simultaneously. The device itself charges via a Micro USB socket. In the box you get the powerbank, a USB to Micro USB cable and a feedback/returns form - remember, this is a value product and the price is very competitive.
This Breett powerbank is a bit bulkier than some 10,000 mAh models and a briefcase rather than pocket model but looks and feels well made. It has a power on button and there are four amber LEDs which indicate the level of charge or power remaining. In use this unit has worked faultlessly with my IPad 3, Samsung Galaxy Tab 3 (7"), plus, Nokia Lumia 520 and Moto G smartphones. The unit will charge the iPad to about 70% and the Samsung Tablet fully plus the smartphones 3 times each. I found charging of the tablets in particular, quicker than I expected. The powerbank itself takes around 3.5 to 4 hours to fully charge.
For the money this powerbank delivers fully but without frills - no integral leads, cases etc. but you do get a tough, powerful powerbank that you won't mind slopping about in your briefcase or rucksack. Recommended.
