I received one of these as a 'for review' unit but there were no under the table deals involving a positive review in exchange.
This charger's distinguishing characteristic is that it comes with two 5V/2A ports and another two 5V/1A charging ports for a total of four. Unlike most USB chargers that try to be all things to all people and provide one 'Apple-optimized' and one 'non-Apple' port or one 1A and one 2A charging ports, therefore making them into 'single port' chargers most of the time, you can actually use all four ports to charge perhaps two phones and two tablets at the same time and this is a good thing.
For your money you get the charger body that comes with a status light and non-foldable prongs that plug into standard AC outlets. You supply the USB cables. The 2A outputs are better suited for the larger devices such as tablets but I found that it charged our phones as well. It even charged our HP Chromebook 11 which is happiest when it gets 3A but accepts anything from 1A up to 3A.
I can't think of no 'negatives' for as long as you are not looking for something 'small' or 'portable' in which case you should be looking elsewhere.
The price is so cheap!
