Well I was going to return this but for the price I honestly couldn't be bothered. It got two stars in that it works (kinda) and I only really want to give out 1 star to products that genuinely do not work. It straight up refused to charge a nexus 7, tried with three different usb leads (all official charging leads from various manufacturers, including asus' official nexus 7 charger) and all charging ports on the device. It did charge my phone (old HTC desire), but even in the 'high power' 1 AMP slot it still only put the phone into USB charging mode instead of AC which is worse than useless, unlike the branded 1 AMP HTC charger, which puts it into AC charging just fine. It also failed to charge my partners phone at all (cheap Samsung, don't know the model). V dissatisfied, will not use the brand or seller again.
