Questions about this item

Will the 1.7 mm centre pin wear out and need replacement?

The 1.7 mm centre pin is a solid metal contact; it does not wear out under normal insertion cycles, so no scheduled replacement is required.

What limit appears first during continuous 65 W load — the 3.5 A current ceiling or thermal protection?

The 3.5 A current ceiling is the hard electrical limit; sustained 65 W output stays within that rating, so thermal protection only activates if ventilation is blocked.
