I love my Microsoft Surface Pro 3, but third party accessories are sometimes hard to find. Microsoft themselves doesn’t even make a car charger, which, thankfully, Amsam has addressed.

The Amsam Microsoft Surface Pro 3 / Pro 4 Car Charger Adapter accepts 12 – 24V input and outputs the expected 12V, 2.58A. As you would expect, there is short circuit and overload protection built-in. Compatibility is with the Surface Pro 3 and Surface Pro 4, although not with the Surface Pro 4 with M3 processor.

Now, for a negative. While the cord is of sufficient length, the magnet that holds the cord to the Surface Pro is a bit on the weak side, so it doesn’t stay in quite as securely as it probably should.

While the Amsam Microsoft Surface Pro 3 / Pro 4 Car Charger Adapter is not perfect, the unique value proposition still makes it worth considering for keeping your Surface Pro charged in the car.

Thanks to Amsam for the review unit.
