If you take a good long look around your living room, you'll probably be surprised at just how many electronic devices you own that have USB ports. And that's what makes this ultra-compact torch so genius. Plug it into any powered USB port — whether it's on a computer, an extension cord, or even a portable charger — and you've got light.
The LedLight is just seven bucks (plus eight for shipping to the US) and will run for years and years, and even has simple swipe-based controls on the back. Swipe it once to turn the light off, swipe it again to turn it back on. It's that simple, in every way possible. [Tindie - USB LedLight]
