Questions about this item

How do I connect the magnetic plug and which orientation is correct?

Align the magnetic connector with the Surface charging port; it snaps on in either direction. The 6.2 ft DC cable and 3.3 ft AC cord then plug into the 65 W brick and a 100-240 V outlet.

What part will need replacement first and when?

The AC cable and DC cable are the only wear items; inspect them every 12 months for fraying or loose magnetic pins and swap the affected cord if damage appears.

At what sustained load does the adapter hit its thermal limit?

Continuous 65 W output (15 V at 4 A) triggers the built-in overload cut-off; the unit will shut down until it cools, so avoid running at full load in confined spaces.
