Energizer dongle charges cellphones from AAs
Om Malik has news of a super-small battery pack from Energizer that may soon be commercially available for charging cellphones with regular or lithium AA batteries. GigaOm has some shots of the, well, battery-sized device, which uses "some amazing circuitry" to perform its wizardry and accepts short adapter wires for different phone models. The chargers supposedly provide phones with one or two top-offs, although we have some doubts that a AA could fill up our extended battery-sportin' smartphones. Still, with these batteries relatively cheap and widespread, they could provide a real alternative to products like the Cellboost- assuming you actually remember to bring the minuscule charger along in your travels.
