Review on Surface RT Surface Pro 1 Surface Pro 2 Charger Adapter with USB, Model: 1536, 12V, 3.6A, 48W - Ideal for Accessory Charging by Mark Gilbert

The product seems to work just as well as the original (I use it on the original Surface Pro) and comes with a much longer power cord from the transformer to the outlet. This is especially nice in hotels where the outlet is far from the desk. It also has a USB port on the transformer for charging a cellphone or other device. The item was also well packaged and delivered quickly.
