Imagine your car breaks down on the road in the middle of nowhere. If your cell phone’s battery dies then how long will it be before someone finds you? When someone does come along is it the person you want to meet in the middle of nowhere? Never have this happen as there’s now a solution. The SpareOne ($50) is an emergency mobile phone powered by a single AA lithium battery. This battery gives the phone a 15 year shelf life before you have to replace the battery and it can make calls anywhere around the world via GSM. To make it work you just insert the battery and your SIM card. If you don’t have a SIM card to place in the phone it will still work for emergency calls to the specific emergency number in your country via the big red exclamation point button in the center of the phone. The SpareOne is not only good for emergency situations in your own country such as car breaking down or natural disasters but can come in handy if you’re visiting a foreign country. So never be stuck out without a line of communication again with the SpareOne emergency phone.
