Forget about recharging the 60 Euros, SpareOne basic mobile phone, running on single AA battery, for the next 15 years, for use as a backup phone.
The phone goes on sale on March 15. The idea is that you can keep it there without worrying if it's charged or not. Most mobiles will be dead over time, even if switched off.
The SpareOne can be pre-programmed for instant access to phone numbers of key contacts, including the relevant emergency services in any location, the Daily Mail reports.
As the phone's developer, XPAL Power, says: "It's essentially designed to make and receive the most important calls, no matter what."
The SpareOne's is also able to automatically transmit its location via its mobile ID, plus has a built-in torch - and unlike so many of today's gadgets, it even comes with the AA battery included.
The SpareOne phone is launching at the Consumer Electronics Show in Las Vegas this week, priced $49.99; international versions will follow later this year.
