Engadget > How-To: Solar charge your SPOT Smart Watch (and an iPod)

If you own a Suunto SPOT Smart Watch you usually charge it via plugging it in to an outlet or with the included USB charger (which in turn is plugged into your computer). We’re going to show you how to make a pretty cheap and easy solar charger for your watch that doesn’t touch any of the included cable(s) at all. And what we’re going to cover will most likely apply to many other USB powered gadgets you have as well, so even if you don’t have a Suunto N3 SPOT watch, there’s some good info here.

As an added bonus, we’re going to give you a sneak peak at a solar powered charger for Apple’s iPod. If you want to see that, just skip to the end.

Ingredients
• Sunnto N3 SPOT Smart Watch
