It’s a pleasure to come across gadgets these days that feature an eco-friendly alternative to juice them up in need. Like the recent shake-powered MP3 player, these walkie-talkies too are tweaked to live up to your expectations at any time. Befitted with a wind-up mechanism, it sports a transmitting power of 0.5W with a talk range up to 3km and boasts of an audio output of 200mW. So whether you work as an outdoor professional or just want to keep track of kids in the backyard you’ll appreciate these never-give-up walkie-talkies that can also be fed via mains adaptor or USB. 
The rechargeable lithium battery suffices for 1.5hr talk-time, 8hr standby when fully powered. And after 1 minute cranking you can avail 2 minutes talk-time along with 10 minutes standby time. Although the product page says that it’s out of stock, you can mail them for further intimation. That is, if you are in need of radio communication gadgets and if I have managed to convince you about green factor of these eco-walkie-talkies.
