Microsoft Surface Pro 3 and Pro 4 Cable

Cable: Connects from the V72 Laptop Battery to a Microsoft Surface Pro 3 or Surface Pro 4 tablet for charging at 12V. Adapter is not certified by Microsoft, but since there is no DC charging option for the Surface Pro 3 / Pro 4, this cable is the best option for charging from an external battery. Surface Pro 3 / Pro 4 adapter plug on one side and a male 5.5x2.5mm plug on the other.


Microsoft: Charges Microsoft Surface Pro 3 tablets from the V72 Laptop Battery. Confirm that the voltage switch on the battery is set to 12V. For extended battery capacity while charging, charge the Surface Pro 3 while asleep or turned off.
