What this adapter does

This two-pack converts a USB-C Power Delivery source into a magnetic connector that fits Microsoft Surface Pro, Book, Laptop, Go and Duo 2 devices. Each unit accepts 15 V 3 A, 20 V 3.25 A or 20 V 5 A input and delivers up to 102 W through a 6.8 A rated magnetic tip. The aluminium housing weighs 0.018 kg and measures 14.33 in by 12.83 in by 9.06 in.

Who should buy it and who should not

Surface owners who already carry a PD charger rated at 45 W, 60 W, 85 W, 96 W or 100 W and want a compact magnetic tip for daily charging, travel or a spare at the office. Buyers who need data transfer through the same cable should look elsewhere because the adapter only passes power. Anyone without a compliant PD source cannot use these adapters.

What the two-pack changes

Having two identical magnetic tips lets you keep one at a desk and one in a bag without swapping cables. Both adapters share the same smart PD chip that auto-negotiates 15 V or 20 V profiles and the same strong magnetic alignment for secure docking. The bundle simply doubles the convenience for multi-location charging.

Questions about this item

What USB-C power adapter specifications are required for this 102W magnetic charger to work?

Use a PD power adapter with output of 15V 3A, 20V 3.25A, or 20V 5A rated at 45W, 60W, or 100W and above. The USB-C cable must also support PD protocol.

Will this adapter charge older Surface models that originally used 45W or 60W power supplies?

Yes, the built-in PD smart chip auto-identifies the Surface series voltage and current, providing backward compatibility for models like Surface Pro 3 through 10 and Surface Book 1 through 3.

How can I confirm the magnetic connection is charging at the full 6.8A rate?

The magnetic interface auto-aligns and locks securely when brought near the Surface port. Stable charging indicates proper connection; the adapter does not support data transmission.
