Dedicated Docking Station Adapter

This 48W AC adapter is built specifically for the Microsoft Surface Pro 3 Docking Station models 1627 and 1664. It supplies 12V at 4A through a 4.5mm by 3.0mm connector with a centre pin. The unit replaces the original power supply for that docking station only.

Fixed Voltage and Connector Limits

The adapter accepts a worldwide input range of 100V to 240V at 50Hz or 60Hz and draws up to 1.3A. Output is locked to 12V and 4A, so it cannot power devices that require a different voltage or current. The proprietary 4.5mm by 3.0mm barrel connector with a centre pin will not fit other Surface models or third‑party equipment.

Connector Size Determines Compatibility

The 4.5mm by 3.0mm barrel with a centre pin is the single specification that decides fit. If your docking station uses a different connector diameter, pin arrangement or voltage, this adapter will not work. Buyers who need a charger for the Surface tablet itself or for a newer docking station should look elsewhere.
