Power A Raspberry Pi For Free With An EE Power Bar


The EE mobile phone network in the UK is offering its customers a free USB rechargeable battery pack. As I’ve tested plenty of power banks in previous posts I’d thought I would see how long it could run a Raspberry Pi for.

The device itself has a stated capacity of 2600mAh which is just enough to full charge the average smartphone. It comes with a short USB cable which is intended to charge your phone or to charge the device itself from your existing wall charger.

I decided to try a Model B+ and a Pi 2 Model B. The Pi Power Estimator app on Android estimated the runtime to be approximately 7 hours.

Here are the results :

Device Estimate Actual
Model B+ 06:32 to 08:11 6 hrs 50 mins
Pi 2 Model B 05:48 to 07:15 6 hrs 20 mins

The details of the EE Power Bar offer are on the official EE Power Bar web page. It applies to EE, Orange and T-Mobile customers on both pay monthly and pay-as-you-go.

EE state the battery is worth £20 but the reality is you can get similar products for £5-£10. The only cost for me was 35p for the initial text message so this really is a bargain for anyone who is already a customer.
