Questions about this item

Does the 4.8 mm barrel connector wear out and need replacement?

The 4.8 mm external and 1.7 mm internal diameter barrel is a passive part; it only needs replacement if the tip is bent, the sleeve cracks, or the centre pin loosens from repeated insertion.

Which limit appears first during continuous 65 W load — the 18.5 V output or the 3.5 A current ceiling?

The 3.5 A current ceiling is reached first; the adapter maintains 18.5 V until the load tries to draw more than 3.5 A, at which point protection engages.
