This flask-shaped gadget can generate power while you walk. Not much of it, though.
The Ampy Move, about the size and shape of a hip flask, is an external battery that charges whenever you move your body.
You can attach it to your hip with the optional belt clip, stick it in your pocket, use a wrist or leg strap for running or cycling, or just throw it in a bag.
Sadly, it doesn't generate a lot of electricity. It takes an estimate 60+ hours of running to fully charge the 1,800mAh battery -- which is smaller than the one in many phones.
You can top it off with a Micro-USB phone charger, though. The device contours nicely to a leg or arm.
The Ampy Move has two buttons. The one on the left activates four white LEDs that do a poor job of indicating the charge level. If you hold down the right button and shake the device, a blue LED lights up to let you know you're generating a charge.
Here's the optional belt clip that comes in the $130 package. (The device alone is $100.) It holds the Ampy Move securely, but isn't quite as secure as we'd like on a belt or jeans.
Depending on your jacket, you can cover up the device while you exercise.
