The SpareOne: A Cell Phone Powered by One AA Battery
While that newfangled smartphone of yours might be able to do dozens of useful stuff like locate places, get the latest movie schedules, run games and access your social networks, constantly running all of these apps takes a huge toll on your phone's battery life. Enter the petite SpareOne phone: it's a no-frills, back-to-basics power efficient device that does what mobile phones were made for in the first place - make phone calls. Developed by the folks behind PowerSkin and Energizer, the single AA battery-powered phone reportedly maintains its charge for 15 years! Although that's going to be actually lower, considering that you are going to use the phone, after all.
With a reported talk time of 10 hours and a $49.99 price, you might not be using the SpareOne phone for an Angry Birds playtime session, but you'll definitely appreciate the phone's power efficiency and affordability.
