Callpod’s Fueltank Uno and Duo

The Fueltank Uno ($50) packs a rechargeable lithium-ion battery, promising to replenish your portable device up to 4-times over. In terms of the new iPod Nano, that’s an additional 96-hours of music. In terms of a BlackBerry Curve, that could add as much as 24-hours of talk time. Needless to say, referring to the Fueltank Uno as just an “emergency device charger” does a disservice to the real versatility of the unit. For roadtrips and short travels this charger enables you to leave your cables and adapters at home, while significantly reducing your dependency on power outlets. In fact, given that most of us chalk up charging with the other chores we’d rather not do, such a useful little power-pack could easily find its way into the daily routine of the moderate technophile. For the more dedicated gadget enthusiast, there’s the Fueltank Duo.

Based on the same technology, the Duo ($70) offers the potential to charge two devices simultaneously. Backing up this bifurcation of power is a beefy capacity of 7-times that of your average mobile phone. The Duo (3.4"W x 4.9"L x 0.722"H) weighs 8-ounces and is roughly double the size of the Uno (1.94"W x 4.89"L x 0.78"H, 3.5oz). Both feature LED-lights indicating the remaining charge in the ‘tank.’

As for compatibility, Callpod has built a reputation for its wide range of product support. Both chargers ship with a Mini-USB adapter, while the Uno also includes an iPhone/iPod adapter. Then there’s the Chargepod line of adapters, supporting over 3,000 devices with dozens of fittings. Fortunately, if you’re not covered by the aforementioned connectors, the Uno and Duo come with a coupon for 1 free adapter.

Whatever your needs, the Fueltanks provide substantial backup power with a wide range of support to ensure that even if you switch phones, you’ve still got a great accessory to extend your battery life.
