Your car's broken down. Your phone's out of battery. Hell, it's always out of battery these days. What do you do? Well, if Xpal Power has anything to do with it you'll just pick up your Spare One.
Designed specifically for emergency situations, this super-cheap phone runs from a single AA battery reports Engadget from CES. Xpal claims that the standby time with a single battery is a staggering 15 years. Fifteen years! That's over half my lifetime to date.
(I'm not entirely sure how they can guarantee that claim, for what it's worth — they certainty didn't test it in real time.)
Even better, it's dual-band and is designed to transmit its location alongside its call ID. Each phone comes with a microSIM (and a battery! woop!) and costs $US49.99. That's pretty cheap for peace of mind. [Engadget]
