65W adapter with USB-A port

This 65-watt AC adapter delivers 15 volts at 4 amps through a magnetic connector and includes a USB-A port supplying 5 volts at 1 amp for charging a phone simultaneously. It replaces Dell model A1706 and supports the full range of Surface Pro, Surface Laptop, Surface Book i5 and Surface Go devices listed in the compatibility data. The unit accepts 100 to 240 volts AC at 50 or 60 hertz and comes with a power supply cord.

Not for Surface Laptop Studio i7 or Studio 2

Buyers who need to charge a Surface Laptop Studio with an i7 processor or the second-generation Studio should look elsewhere because this adapter is explicitly excluded from those models. It is also unsuitable for anyone requiring a higher-output charger such as the 85-watt or 96-watt variants referenced in the specifications.

65W output at 15V 4A

The single specification that determines fit is the 65-watt DC output rated at 15 volts and 4 amps, matching the original Surface charger requirement for the supported device families.

Questions about this item

Does the 15 V 4 A output generate noticeable heat when the adapter runs all day?

The 65 W unit is built with multiple safeguards against overheating, so it stays cool during extended charging sessions.

What cable or connector must I already have to use this charger with my Surface?

Nothing extra is needed — the magnetic Surface Connect tip is fixed to the adapter and the 10 ft AC cord is included in the box.

Will the 65 W brick charge a Surface Book 2 i5 at the same speed as the original 45 W supply?

Yes — it delivers 15 V at 4 A for 65 W, which is faster than the 45 W adapter while remaining fully compatible with the Book 2 i5.
