Questions about this item

Does the TPN-DA11 adapter match my laptop's 4.5 mm by 3.0 mm charging port?

Yes, the barrel connector measures 4.5 mm outer diameter and 3.0 mm inner diameter, so it fits laptops that require that exact tip size.

Will a 135 W 19.5 V 6.9 A brick run cooler than a lower-wattage unit under the same load?

The adapter delivers up to 135 watts at 19.5 volts and 6.9 amps; it only draws the current your laptop requests, so it runs within its thermal design for that load.
