Oxford Street 12000Mah usb battery pack used for playing Ingress with a SGS3. Gave 4 hours constant Ingress scanner usage, followed by 5 hours using SGS3 WiFi tethered to my netbook. Usually a full charged SGS3 lasts a couple of hours while playing Ingress. Now I can go out all day and the phone stays at about 90% throughout with the Ingress app on all day.
The casing is very well built, with good rounded edges, if a little slippy. I have it in a zipped pocket inside my jacket so it won't drop out if I lean down to tie my shoelaces. It is less heavy and bulky than I expected, I do not notice it in my pocket.
I was disappointed to find it will not charge my nicolites e cigs. They begin charging but the Oxford Street battery does not recognize there's something plugged in an swithces off. But as there are two usb outlets, I can charge my ecig batteries as long as I am charging my SGS3 at the same time, because that keeps the battery pack activated.
It will also not recognize my old Nokia phone, switches off after the normal ten second shut down period. But I do not use the old Nokia anymore.
Oxford Street 12000Mah takes about 6 hours to charge back up from empty, through my netbook usb.
Really very useful battery pack and I'm surprised by the good quality casing considering this is the cheapest of the type I found after looking at a dozen.

1) No charger. Had I not already owned a mini-usb wall charger then I wouldn't have been able to use this product at all.
2) No instructions. How long do I charge it for? Do I leave it switched on to charge or switched off? Oh that's right, you have to guess.
3) Uh... it doesn't work. Tried every way of charging this stupid lump of plastic and the most life I get out of it is the lights flashing up when I first plug it into the wall. Doesn't mean anything though, because once I unplug it from the socket (after 5 hours) it won't switch on. Try plugging phone into it. Nada.

Point 3 is obviously just a faulty unit (nice quality control there, guys) but the first two points still stand. DO NOT BUY.

I will now be emailing Amazon for a refund and I'll be pissed if I have to pay for any postage.

Used this at Reading to charge my Xperia S at Reading festival. The phone has a 1750mAh battery, so theoretically, it should be able to charge my phone nearly 7 times.

I got 2 full charges out of the battery. It charged it from 9% to 100%, and then from 3% to 100%. Then next time it charged it from 10% to 29%. This means that I only got about 3605mAh from it. So, either I got a faulty product, or it isn't as advertised.

It didn't heat up or malfunction when it was working and it did give a consistent charge, so I won't rate it too low. But just know that if you need to charge something with a large battery, it might not work.

I have now tried several times, but it is not possible to charge my IPAD3 to a level higher than 38%, which clearly shows that the capacity of the battery package is much less than the stated 12.000 Mah. Can only be used to charge my iPhone.

The charger didn't cost very much and unfortunately it showed. The battery would perhaps charge my phone 1.5 times (3000mah battery) but not close to the 4x you should theoretically get. After about 3 months it gave up charging altogether. Replaced with a 10500mah lumsing which is everything I had expected.

Definitely not 12000Mah, it charges my 3100mah smartphone twice, and then it's dead. so it's almost half the capacity advertised. the 1A port outputs 2A, and same goes with the 2A port.

If this were advertised as 6000mah, I would probably give it 4 stars. As the build quality is okay.

But thumbs down for false advertising.

This is a brilliant addition to a back pack. It charges a flat IPod and still has charge left over for the IPhone. Very very good and would recommend to anyone who needs emergency charging when away from civilization!

The only, very minor, irritant is that it wouldn't charge my Nokia 1630c (5v/350mAh) without a Nexus 7 also being connected and charging. The Power bank would switch off as it didn't recognise that anything was attached. However my wife's Nokia 100 (5v/450mAh) was enough to keep it going on its own.
The Power bank would charge a Nexus 7 with 2 full charges. As I tended to use the Nexus for less than a full charge, I would get about 3 part charges. As the N7 battery's capacity is 4325mAh, that seems to equate to around the advertised 12000 mAh. The rated output is 5v~2.1A & 5v~1A
To charge the Power bank would take approximately 8+hrs. Up to 12 when attached to computer. You could use this -SHOP AROUND®UK Premium WHITE USB Port Wall Mains Charger High Quality Adapter Plug For ALL iPad iPhone 3G 3GS 4 4S 5 iPod iTouch 5 Nano Shuffle Samsung S2 S3 S3 Mini S4 S4 Note Note2 Mini Sony Xperia X Z
It charged up my sister's iPhone.
Best described as chunky @ 10x7x2cms, I have used it tethered to the Nexus whilst walking and aim to connect it to the Sat-Nav on a bicycle, if I can waterproof the combination.
Update
Didn't make it clear that the pack is 8880mAh @ 5v, (3.7V x 12000mAh/5V) not 12000 as written above. Sorry bad mistake. It does charge Nexus up twice and that is it. 4325mAh x 2 = 8860mAh.
To cap it all, it does charge the Nokia 1630c on its own, now. ???
