I don't have one of those usb multimeterers to measure it exactly, but it does appear that for up to 3-4 devices it can give 2A on each port (at least the specs indicate so, and the tablets show the fast charging logo).

I bought it a couple of weeks ago (at £9.99). I don't have any devices that support QC3, but so far it works perfectly fine and charges simultaneously a couple of tablets and a phone at 5V 2A.

£4.99 in Prenton (locked away in the electronics cabinet where they're priced at £9.99. I only discovered the reduction when I bought one). Several left.

and I hope these help:

I don't think this is Qualcomm 2/3 fast charger. look at box image. also, I went to store and there.is no qualcom ref on the box.

Nothing on the image suggests it is. doesn't say this on the Aldi website either (a user comment makes ref to Qualcomm), but wouldnt trust that.

fast charge / usb3 are not Qualcomm 3 quick charge

the Qualcomm chargers have variable voltage.

hope this helps

I got a few of these and one already died with a flashing green light next to the QC port. There is also a small bit of coil whine when attached devices have fully charged and at 100%.

Just bought one from my local one (Basford, Notts) at £9.99. seems to be working fine. Liking the matte feel around the charging unit. Will report back once I get my xiaomi mi5 from Aliexpress which supports QC3.0 so till then.

£9.99 in Norwood Junction branch this morning

I got this a few weeks ago for an earlier deal. The product is good. It's QC 3 but I use a HTC one m8 which is QC 2. This device is backwards compatible and works fine with my phone (the charging light turns from green to orange to indicate quick charging) it charges my phone really quick to 80%. Great product!!

I bought two at full price and thought that was a bargain - might pick up more for my Mum/ travel

Thanks, seems a good price for this sort of thing.

Qualcomm Quick Charge support list to see if your device is QC supported (it's not a comprehensive list, but it's better than nothing):

Cut them to £5 in Aldi Prestwick

thats quite cool if it works cheaper than an actual plug

Does this need mains?
