85W Dell AC Adapter for Surface
This 85W Dell AC adapter delivers 20V at 11.8A and is compatible with Microsoft Surface Pro, Laptop, Book and Go models including 1706, 1724, 1735, 1796, 1800, 1866 and 1867. It supports power delivery at 65W, 44W, 36W and 24W with an additional USB port for charging another device. The unit includes a power supply cord and features automatic magnetic connection near the port. Buyers needing a charger for non-Surface laptops or higher wattage requirements should look elsewhere.
Magnetic tip and long cable simplify setup
The connector uses automatic adsorption so it aligns without precise aiming, and the super long cable reaches distant outlets. Built-in safeguards protect against over-charging, over-current, over-voltage, short circuit and high temperature. To avoid overheating, never operate the charger on beds, sofas or blankets where ventilation is blocked. The cord has been tested to over 30000 bends for durability. Installers who route cables through tight grommets should verify the connector dimensions beforehand.
Verify model number and input voltage first
Confirm your Surface device appears in the compatible model list such as 1625, 1703, 1736, 1769, 1782 or 1873 before ordering. The adapter accepts 100-240V 50/60Hz input for worldwide use. Check that your existing power cord uses a standard C5 or C7 inlet if you plan to reuse it. Users with damaged charging ports or non-standard voltage requirements cannot use this adapter.

Questions about this item
How can I confirm the DELL DHM1749 85W adapter is working correctly after plugging it in?
The LED indicator on the connector lights up when power is flowing, and the Surface device shows the charging icon on its screen within seconds of attachment.

The package includes one 65W power adapter and one AC power supply cord; no extra cables or tips are required for the listed Surface models.
Which power rating should I choose among the 24W, 36W, 44W and 65W versions for my Surface device?
Select the rating that matches or exceeds your device’s original charger — 65W covers Pro 8 and Laptop models needing 15V 4A, while 44W, 36W and 24W suit lower-draw tablets and Go models.
