Laptop ac power adapter

Advertisement

My laptop is more than 75 watts (e.g. 120 watts). Will
this adapter damage my laptop?
This is a 75 watt adapter and it should NOT be used with laptops
that require more than 75 watts of power.
I notice that the adapter is warm when I use it. Is this a
problem?
During standard operation the adapter body may feel warm,
and this is normal. The adapter should always be placed in a
ventilated area in order to prevent over-heating.
How long is the cord from the wall to the laptop?
The AC input cord is 5.7 feet (174 cm) and the DC output cord is
3.9 feet (119 cm).
If I leave the adapter plugged in when I'm not using it
does it waste energy?
This Rocketfish adapter meets EnergyStar and CEC V energy
requirements which means it is an energy-efficient product
designed to conserve power. When the adapter is plugged in
and not being used it draws less than 0.5W of power.
