This is what I'm currently using;

Levin Solwing 13 W PV Solar Panel;

http://www.amazon.co.uk/Levin-trade-Ultr...solar+panel+13w

Which has two USB outputs

i) Can recharge directly an Olight R40 torch via USB

and a Aukey 7500mah Waterproof Portable Charger External Battery

ii) Can also recharge either a Landrover A8 smartphone or charge or run a Eye TV Wifi Mobile hotspot to view Digiral TV and Broadcast Radio on the A8.

The Aukey powerpack and A8 Smartphone fit perfectly into a Condor DigiPouch perfectly.
