Being able to charge your mobile gadgets is pretty important. After all, with a drained battery, a phone or MP3 player isn’t going to do much good, is it? There are a variety of portable battery solutions out there, but what if you’re also trying to be eco-friendly when charging your gadgets? Sure, you have the option of going solar, but that depends on good sunshine. Wind power is good, as long as you can keep a steady breeze. So what about using your own kinetic energy?

The nPower PEG is a small device that can be placed in your pocket, backpack, or wherever. When you’re walking, it will then capture the energy built up from your movement and store it in a battery. You can then plug in a mobile device such as a phone to get a bit of extra juice. Unfortunately it takes a lot of walking to get even a little bit of energy. Here are a few examples:

• 1 minute of walking provides approximately 1 minute of listening time on an iPod Nano
• 11 minutes of walking provides approximately 1 minute of talk time on an iPhone 2G
• 26 minutes of walking provides approximately 1 minute of talk time on an iPhone 3

Of course, if you’re walking a lot anyway, you’ll eventually get it charged up. However, if you’re someone that spends most of their time in a chair, this might not be the thing for you. Also, the $160 price tag might be enough to keep you from purchasing it, regardless of your walking habits.
