Energizer's releasing a portable battery charger called "Energi To Go" that charges 80% of cellphone brands on the market now. There's two models, a two battery charger for cellphones, and a four battery charger for audio and gaming devices (iPods and PSPs). This sounds similar to Turbo Charger AA chargers, but costs a bit less.
Two two battery charger has an MSRP of $19.99 and the four battery charger has an MSRP of $29.99. Their website for this product isn't available until August 28, so don't go clicking on it now. Really. Don't click it. We'll be watching.
