Bullet Shaped Cell Phone Charger
Tiny, probably over rated, but convenient. The Turbo Charge is a bullet shaped emergency charger. Just connect to your cell phone and get a reported 2 hours of talk time, and up to 40 hours of standby time (obviously they don’t know my phone). Its blue glowing tip turns off when the single and replaceable AA battery is dead, and comes with the necessary adapter. Available here for $20.
