I have one and it charges two ipad 2's at the same time. It takes longer than normal but it will charge them
I bought one at the weekend, was going to post here, but it's not very good in my opinion. I tried my Galaxy Nexus and it took several hours to charge, with the Samsung charger it takes just over an hour. Plan to return mine this weekend.
Does this allow you to plug something with a three pin plug in normally at the same time as charging off the USB outputs?

Yes it does.
Looks like a micro-toaster
Anyone know any deals for standard USB mains adapters?

I bought three off Play a few months ago and they were rubbish. They "worked" as in they would charge the phone but whilst plugged in had this strange effect of freezing the phone until unplugged again.
Yep I'm almost certain they had these in the Camden store the other day too. There were also a few other bits - I almost bought an HP keyboard, then decided against it.
£15 in Sainsbury's Brighouse this evening.
The reason it takes longer to charge things is that it only working in USB mode, and not AC mode. You can check this on the phone. On android, you can check this by looking in menu>settings>about phone>status. My other (generic) usb mains charger does the same. However, all the chargers that came with our phones (3 in the family) charges in AC mode. As others have said, it does work, but takes longer to charge.
Got 3 in Sainsbury's Derby (Ossy Rd) about 10 left as of 8pm.. Bargain Thanks
This pumps out 0.5A @ 5V where as a typical Ipad charger gives 2.1A @ 5V. It will take ages to charge.

It does has 1000ma on the packaging somewhere though. Any idea why devices aren't drawing the full amount?
I have one of these. Can't charge my HTC Desire and my wife's Motorola Defy at the same time, so I just use one of the USB ports. Also found the blue LED to be VERY bright. Had to stick some electrical tape over. I do like the pass through power socket, though.

You need to use a USB 'CHARGE' cable and not a fully wired USB DATA cable.
Android phones detect when the DATA pins are shorted together and then place the phone in AC charge mode which draws 1A (1000mA) instead of the 0.5A (500mA) USB PC connected mode.

The AC charger that comes with Android phones will already have the DATA pins shorted thus negating the need for a cable that does it ergo a normal fully wired USB PC DATA cable can be used and still allow the device to draw the higher 1A (1000mA).

Why these 3rd party AC chargers don't do that is beyond me ?!?!?!
A charge ONLY micro/mini..etc USB cable can be bought from ebay for pennys and the vast majority of these will have the DATA lines shorted to enable AC mode.
Maybe everyone has forgot the point of these, the idea isn't so you can charge it as quick as a plug, otherwise you would just use a plug, idea is to give you the ability to trickle charge if needed or to just give you enough time, is ideal for running my usb doing deck whilst using the laptop for mixing
I've been looking for a usb mains charger for my kindle 4 and partner's e-cigarette charger to save plugging into pc. I didn't fancy the cheapos on Amazon, but I spotted one in Asda yesterday a full charging kit with all the different attachments and usb inputs into mains plug as well as the added option of the car charger with usb input too.... down from £7 to £4. Didn't buy as was in a hurry but looks like it would suit my needs perfectly.
as above, mine wont charge an ipod touch4 and a samsung wave together, but the passthrough is great...and 3 @£3.50 last year was a bailly bargain...
The multi plug versions in saisburies tonight didn't have usb's ?? I'm sure they did at the weekend?? they must be getting in different stock...
Just got mine! Loads in the Toplow/Burnham branch if anyone needs to find stock!
Had one of these but returned it. Despite stating it is iPad compatible and outputs 1000ma the iPad status shows as "not charging" and it takes a whole day to complete a full charge.
