Also... this is no different to majority of USB mobile chargers. I have plenty battery packs that you plug into wall to charge and you can then just plug a usb in the other side for simultaneous iPhone charging. Plus, one charges iPhones 400% the other ~600%.
I pre-ordered one too. I was happy with my ChargeKey (also from Nomad), but I hate pulling out my laptop on the plane just to charge my phone. And my portable backup battery takes up too much space in the seat pocket. NomadPlus sounds like it could do the trick...
