Surface Pro 3 compatible

I am a student and use the Pro 3 mainly in the FH for scripts and notes. Frequently I am there for 7 hours straight and about 40 people in some lectures it is very important not to rely on an electrical outlet.

The mobile use of the tablets can be tripled with this device !!! The charging time of the tablets is of course not to ran it would need if I to the associated power supply infect but that's not necessary have the power bank in the backpack, and then lead the cable up on the table.
Now have the Surface charged about 6 hours in operation and with a charge of battery is empty and the tablet again fully. So I have now increased mobile use my Surface Pro 3 from 6-7 hours to over 18 hours. I am fully satisfied. (So ​​with mobile usage I mean when the Pro 3 is charged: 6hrs discharged, 6 hours Charging and again 6 hours discharge).
When off the Surface 3 per powerbank is after a complete charging cycle at about 50%.

The associated charging cable is not there but you can get that too here at Amazon and I do not expect that the manufacturer attaches to all adapters.

Processing with my device is OK. The case is on the bottom of plastic, but by the weight falls also significantly lower compared to the other Power Banks I've tested.

Only the different power ratings here on Amazon of 23000mAh I find just as it did in other recessions mentioned very poor. On the housing itself but then is also the correct value of 85Wh.

Recommended Top product especially in conjunction with laptops very since the charging current at DC is out higher than comparable competitive products.

The price is a little more expensive but let everyone know myself how the device looks at his that he wants to invite.
