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.
What gets me with this bank is that it’s output sockets are different currents. So I’d be scared to plug in two devices that require 1A as i think it’d blow the device connected to the 2A slot, unless anyone can tell me differently.
The bank i have (from a different vendor) has 2x 1A ports so i can charge my phone and another small device. This suits me fine as I don’t have a tablet.
So folks like me with only small devices don’t look to be able to get the most out of this power bank.
I have gone through your post and you have excellently written the content on benefits and helpfulness of Powerbank usb. Looking forward for such informative from you.
