Questions about this item

What cables and connectors come with the 1703 65 W adapter, and is a mains lead included?

The adapter has a fixed DC output cable with the Surface connector and a built-in 5 V 1 A USB-A port for phones; a detachable IEC C7 figure-8 mains lead is not included.

My laptop originally shipped with a 44 W unit — will the 65 W version work safely?

Yes. The 1703 delivers 15 V at up to 4 A (65 W) and automatically negotiates the lower 15 V 2.58 A (44 W), 12 V 2.58 A (36 W) or 15 V 1.6 A (24 W) profiles required by earlier Surface models.

What does the 65 W rating mean when the charger is connected to a Surface Pro 7?

At 15 V 4 A the adapter can supply the full 65 W the Pro 7 requests under load, while the extra 5 V 1 A USB port can simultaneously charge a phone at 5 W without reducing power to the laptop.
