While I love my Microsoft Surface Pro 3, some things, like the first party AC adapter, tend to be a bit on the expensive side. That’s why something like the Amsam Microsoft Surface Pro 3 / Pro 4 Charger Adapter is so compelling, because it allows you to inexpensively replace or duplicate the original AC adapter’s performance for the Surface Pro 3 and Surface Pro 4 (although not for the Surface Pro 4 with M3 processor).

The Amsam Microsoft Surface Pro 3 / Pro 4 Charger Adapter accepts 110 – 240V input and outputs the expected 12V, 2.58A. Fortunately, there’s also short circuit and overload protection built-in, so your precious Surface device should remain safe regardless of the power situation.

Now, for some negatives. While the cord that goes from the AC adapter to the wall outlet is of sufficient length, the cord from the AC adapter to the Surface Pro is a bit on the short side. Also, 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 clearly has some flaws, the low price still makes it worth considering as a secondary AC adapter.

Thanks to Amsam for the review unit.
