Rated 1 out of 5 by from I have one of these items. It came bundled with the Raspberry Pi kit. I don't think it does supply 1A never mind 2A. I've tried charging my Galaxy Nexus and Nexus 7 that need 1A and 2A respectively to charge at their usual speed. The Nexus 7 still wasn't fully charged after a full day connected. I checked the status of the charging on the device and it said is was charging via USB (500mA and below) not AC (above 500mA). The same result was seen on the Galaxy Nexus with it reporting USB charging.

Rated 4 out of 5 by from I got this with my Raspberry Pi and I have found it very useful for a number of applications as a charger as well as a power supply. so I am gettinng a couple more. One word of caution though, if you are using it at higher current you must use shorter and/or heavy duty USB cables otherwise the cable drop will limit the current, as it is a very stable 5 volts at the charger.

Rated 3 out of 5 by from Bright little number It does what it promises – handles a phone (Nexus 4) and tablet (Nexus 7) simultaneously – but it also doubles as a nightlight. Not the sort of thing that you want to use in a bedroom. My plan is to get the N22NC which, according to one review, does not try to compete with the Blackpool illuminations. This one can go in the office.

Rated 5 out of 5 by from Very good USB supply I have 4 of these and will shortly be purchasing two more. Used for powering 2 Raspberry Pi's per unit. Absolutely rock solid and no problems with them at all. They are expensive for what they are and should really be half the price but balancing this is the fact they feel like a quality item and mine get heavily used and never had a problem.

Rated 5 out of 5 by from A solid PSU I can only assume the comment prior as to low power was a defective unit. I have run a multi-meter over mine with differential loads whilst powering a Pi and a mini hub, rock steady supply with a strong steady voltage at 5.12v I wish it was cheaper though

Rated 2 out of 5 by from Overated I bought this device to power a Samsung 7inch tablet which requires only a 2amp usb charger. This unit is rated at 2.1amp max but would not charge my tablet. Note also that if you wish to charge two devices at the same time, it would only give 1amp output to each, probably less than required to charge two smartphones. My advice would be to invest in a more powerful charger, even if it is an extra fiver to buy from Maplin.

Rated 5 out of 5 by from Good unit Lost an Apple charger. This replaces it, is cheaper, and has two outputs. LED far too bright, so added a 15k resistor in series...

Please can you tell me which USB is the more powerful one for charging and which is the less output one.

Asked by: Landfall
Both sockets are capable of delivering up to 2.1A but you should only use one if device you are charging requires such a high current. If you are using both outputs at the same time then the load for each device should not exceed 1A

Is it safe to use both outputs at the same time? Eg. Charging two phones at the same time. Thanks.
Asked by: Tyler
As long as the combined power of the two devices does not exceed 2.1 amps then yes, it will be perfectly safe.
