Mobile operators aren't often recognised for their benevolence, but EE caught everyone's attention when it started handing out free portable mobile chargers to customers. In fact, it received over a million requests in just four days, forcing it to "power pause" signups and tell people to try again in a couple of months. If you were one of the unlucky ones, the good news is that EE's self-imposed embargo is now up, meaning you can again claim a free 2,600mAh Power Bar via a 35p text message. As long as you're an EE, Orange or T-Mobile customer, all you have to do is send "POWER" to 365 and wait for your unique code. Once you have that, it's a simple case of popping in to your local EE store to pick it up. Those very same stores will also swap a dead Power Bar out for a fully charged one whenever you want.
