To test the RavPower RP-PB13 we decided to pitch it against the most ideal charging method – a mains plug socket. The devices tested were a Samsung Galaxy S3 mobile phone, Samsung Galaxy S2 mobile phone and a Motorola Xoom 2 tablet. All devices were charged while powered on from just 1% up to 100%.
The Motorola Xoom 2 tablet is the largest device we will be charging with the Ravpower RP-PB13. You can see here that charging via the mains took 4 hours 25 minutes (265 minutes). This was 20 minutes faster than using the RavPower RP-PB-13.
Next was the Samsung Galaxy SII. When charging we found that the recharge time was exactly the same for both mains charging and charging via the Ravpower RP-PB13. A final time of 2 hours 50 minutes (170 minutes) is a great result.
The Samsung Galaxy SIII took 2 hours and 43 minutes (163 minutes) to charge via the mains, whilst the RP-PB13 took 35 minutes extra to get the device to the 100% mark.
Unfortunately after charging two phones the Ravpower RP-PB13 ran out of steam during the charging of the Motorola Xoom 2 at 80%. We restarted the test after recharging the power bank again.
