These days in Japan it is a new gadget by Strap-Ya, which seems to catching attention, it is a back up battery, which can get recharge by itself in to the sun in about 8 to 10 hours and can give your cell phone some extra breath for about 30 minutes. Well this may not seems like a good thing to charge a solar battery for 8 hours and use it for just 30 minutes, but practically it is a good concept to utilize solar energy, as almost everyone aware of the environmental changes are taking place, and about the global warming. You can use it as a key chain and keep it in a strap, which may be the best way to keep it on charging. You can also recharge it by just plugging it into the AC wall socket for three hours. This gadget soon be available in Japan in a week.
