The Eneloop portable solar pack doesn’t look quite as cool as that Energizer charger we’ve been waiting for, but it will supply 5 volts for 2 hours.

To juice up, you connect your USB-charging device to the included Lithium Ion booster pack, which acts as a reservoir drawing power from the panels.
Sanyo claims a full charge to the booster in good sunlight will take 3 days with one panel (¥9,000; about $100) and half that on the two-panel version (¥14,000; about $150). Available only in Japan for the moment. [Sanyo Japan via Akihabara News and PC World]
