The Emergency Phone Charger is a slim metal tube, with space for an AA battery. Just plug the unit into your mobile phone and you get an extra two hours talktime. It’s that straightforward – especially as AA batteries are available just about everywhere, certainly easier to find when you’re out and about than a power point.
The charger comes with four different adaptors, which should make it compatible with most mobile handsets – but check with the website before purchasing. You can pick one up for £5.95.
