In an emergency? This battery-powered phone could bail you out
Emergencies don’t always have the courtesy to occur when your mobile phone is fully charged. That’s the thinking behind the SpareOne, which runs on a single AA battery. Just take a SIM card, stick it in the SpareOne, and you’ve got a functioning phone for voice calls, should your regular smartphone give up the ghost.
In this video report from Mobile World Congress in Barcelona, we take a hands-on look at the $80 SpareOne.
