Energizer USB clip to charge camcorder / DSLR batteries via USB

Energizer's Energi To Go catalog just keeps getting sweeter. After introducing a new range of XPAL battery chargers last month, the company is evidently gearing up to reveal what's likely to be its most convenient and altogether useful product yet. The USB clip you see above is designed to make contact with DSLR and camcorder batteries and provide juice via USB; in other words, it's like a portable, highly mobile DSLR battery charger.OhGizmo points out that you may need one of Energizer's USB-equipped battery packs to charge up the 7.4V cells, but at least we're still talking about a non-proprietary charging connector. Per usual, there's no mention of dollars and cents, but hopefully it'll be rolled out for less than a song
