As you’ll see from the picture, the unit looks much like any standard USB battery pack, albeit a fairly good looking one, with a charging port and power level indicator. The battery has a capacity of 4800 mAh which will fully recharge the average smartphone about twice. The Qi charging plate is on the top and should work with any Qi-enabled smartphone like the Nexus 4. According to the spec, you should be able to charge from both the Qi plate and the USB port at the same time.
The N11 is priced just under US$60 which includes a $10 early adopter discount and free world-wide shipping. It’s pricey enough and you probably could buy a battery and a charger separately for less, but the sheer convenience of a single unit makes it worthwhile. The N11 will be available in early November and I’ll try to get one for review. More information then.
