Picture this. You’re cooking dinner in your tent and your headlamp dies. Picture this too. You’re flicking through a book on your iPhone – got to carry your entire library on the trail – and the screen goes black. Sounds familiar right? Well, get an arm work out and juice up your device at the same time with the Crankmonkey. At 346g, it’s a lightweight asset for any pack.

If you know how to reel a fishing reel, you know how to operate a Crankmonkey. Plug the Mi USB connector into any Mini USB-receiving device, or your Apple sync/charge cord into the standard USB connector and start winding. A ten minute workout will give an iPhone 6 enough charge for 18-20 minutes of chin-wagging, or will power a Petzl headlamp for 6-7 hours. Best thing, the accomplishment you will feel after generating electricity. With your own two hands!

The Crankmoney is suitable for the hiker, cycle tourer, or mountaineer that wants a way to recharge their devices just in case.
