Windup LED Camping Light

These things are getting so efficient, why use them just for camping? One minute of winding gives 30 minutes of light. A full wind gives four hours of 5 LED bright light or 48 hours of nightlight feature with only 2 Amber LED's. It also has a recessed hanging loop "so you can pop it on a table, or string it up on a tree, the top of your tent, whatever. As well as muscle power, it comes with a 12v in-car charger, so you give it a quick boost in the car if you're feeling too knackered after all that trekking to crank it up." Just £19.95 from::I want one of those via ::UberGizmo

Here's a torch on ebay(auction expired but useful information) that will charge a variety of mobiles, too. No idea how well it works, or how long it would take to charge various phones... but I like the idea!

awesome effeciency! It's only a matter of time before these winders replace light switches for home , garage, shed...cool!
I don't think the same tech and efficiency's that are being developed into the 1 and 3 watt LEDs has been applied to the 5mm LEDs yet.
Cant be purchased in the US :(
