BluePack iPhone iPod Backup Battery - £29.95

Keep your iPhone going all weekend

iPhone users are everywhere now, and despite all the fantastic advances in touch screen and internet browsing, the battery life is still as bad as any other phone.

If you're planning in staying on touch with your iPhone at festivals this summer than you shouldn't be without the BluePack back up battery, which gives you a whopping 250 hours of stand-by or 3.5hrs of talk time, enough to see you through the rest of the weekend.
