Do you want to see the most powerfull power bank from Microsoft? Check the DC 34!
This is 12 000 mAh charger which can charge two devices at the same time.
Not only smartphones but also tablets. DC 34 uses a standard USB cables
and ports, you don't need any additional cables and you may charge not only Lumia devices but any other device including iPhone or Samsung.
So we in
Battery Super Saver decided to check this double charger on Lumia 620 and 735 see the video test below:
As you can see this is quite efficient in terms of 620, we have full charge after 1h 28 minutes. For second device 735 it took twice that time and we reached 100% after 3 hours.
Maybe the reason was in the cable user in this test which is not oryginal DC 34 cable (orange one on the video).
What is important to highliht, DC-34 after the test was still 75% full and ready to charge another devices if needed. Moreover according to manufacturer claims that:
"You’ll still have up to 80% capacity if you leave it in your bag for several months." To me it sounds believable. And what do you think?
