There is nothing more frustrating than to have your smartphone run out of juice. Plugging it in a public electrical outlet is not exactly ethical nor safe unattended. The best solution is to have your own battery backup so you’re never caught short. The Bolt available from Photojojo is both a wall charger and portable battery backup rolled up in one!
Smartphones can be charged directly on the wall outlet. But if you have to pack up and go, the Bolt slips into a pocket or purse and will serve to power your smartphone just when you need it. Catch up with email anytime. There is no need to miss that next great photographic opportunity either!
