Forget AA batteries or pre-charge modules there is another way to charge up your mobile phone should you it run out of battery. The Wind Up Phone Charger is an alternative method that will keep you talking when you need too. By winding the charger at 2.5 rotations per second for a total of 3 minutes you can gain up to 8 minutes talk time.
The size is not too big a problem though it will no doubt be much larger than the mobile phone itself. You could easily keep it in a rucksack or briefcase or the glove compartment of your car. It only costs ?Ç¬£6 too, which is a bonus.
I?¢‚Ç¨‚Ñ¢d recommend buying them as presents for anyone who uses the ?¢‚Ç¨?ìran out of battery?¢‚Ç¨¬ù excuse far too often.
