If you’re the sort of person who runs their phone battery down to nothing on a regular basis, IOGear’s new GearJuice, could provide just the bit of insurance you need to stay connected. It’s basically a shell that fits around a AA battery, with a bit of circuitry, a keychain connector, and a connector with cap on one end. The idea is that you carry it around in your pocket, and if your phone’s charge runs out, you plug in the GearJuice and give it a battery’s worth of charge.
I tried one out, and for $11.99 (plus shipping) it works as advertised. A typical AA alkaline battery holds about enough power for a full charge of a mobile phone, so as long as you keep the battery fresh it should keep you going long enough to get back to your charger. The big limitation is that your phone needs to charge through a mini-USB connector (like those found on Blackberry or Motorola devices), rather than some proprietary connection.
