Questions about this item

Will the 19.5 V 12.30 A output connector wear out and need replacement?

The barrel connector is rated for thousands of insertion cycles; under normal use it lasts the adapter's lifetime and rarely requires replacement.

What limit appears first when the 240 W adapter runs continuously at full load?

Thermal protection engages first; sustained maximum output raises internal temperature until the unit throttles or shuts down to prevent damage.
