Questions about this item

Does the 19.5V 6.9A output connector wear out and need replacement?

The barrel connector is rated for thousands of insertion cycles; under normal daily use it lasts the adapter's lifetime without replacement.

What limits continuous 135W output first — heat or input voltage?

Internal over-temperature protection trips before input voltage becomes a constraint, so sustained 135W is limited by thermal headroom.

How much heat and fan noise does the 135W brick produce when running all day?

The unit is passively cooled with no fan; surface temperature rises under full load but stays within safety limits and produces zero audible noise.
