The problem with most wall chargers is that you never know how long to leave your gadget connected to them, unless you actually turn on your gadget and look at the battery status. Well VogDUO’s Green Wall Charger is set to change all of that. This USB wall charger lets you set the charging time to 2, 4, 6 or 8 hours so that it will stop consuming any power when the time is up. This way you’ll know when you’re gadget is done charging and you’ll stop wasting electricity too! There is no word on pricing yet for the PS0517 Green Wall Charger, but it does seem to be iPad and iPhone compatible, it’s able to charge unto 4 devices at once, and it even sports indicator lights.
