Questions about this item

Does the 85W adapter run hot or make noise when used continuously?

The brick delivers 20V at 11.8A with built-in thermal and overload cut-off, so it stays cool and silent during all-day operation.

What cables or connectors must I already have to use this charger?

It includes a 6.5 ft DC cable with a magnetic Surface connector and a 3.3 ft AC cord with a standard two-pin plug, so no extra cables are required.

Will the 15V 4A output safely charge my older Surface Pro 3 or Surface Book 1?

Yes, the adapter automatically identifies the device and adjusts to 44W, 39W, 36W or 24W modes, matching the original charger for those models.
