UK mobile operator EE's offer to give its customers a free portable smartphone battery charger has proven to be a popular one, with over 1 million requests in just the first four days.

EE Power Bar

EE launched the offer to give its customers a free 2,600mAh Power Bar battery charger on Thursday, April 16. Users could get the freebie by texting on their smartphones to get a promotional code. Today, the company said:

We had five times more requests in the first 24 hours of the promotion than even the most popular smartphone launch in the UK and visits to store were up as much as 300% over the weekend. While we fulfil the requests we've already taken, we're taking a short 'power pause' to replenish stock. More Power Bars are on their way for our second release at the end of June. If customers text in now, they will be advised to text back from 8am on June 24th – there will be no charge for these texts if no code is received.

People who have already received their code, via text, for their free EE Power Bar will still be able to go to their local EE store to pick them up.
