I used a UPS that had a modified sine wave inverter and it made my
laptop charger run excessively hot. That was one time during a Field Day
event, so I don't know if it would have shortened the life of the
charger. Currently I am using a pure sine wave inverter made by Samlex
and the laptop charger plugged into that inverter feels like room
temperature.

I found a old 150watt DC to AC converter. It's a good 10 to 15
years old and has never been used.
Looking to use it to power the AC adapter/charger for my laptop.
IT's rated for 130watts.
I'm guessing it's a *modified sinewave* inverter due to the age.
Will this thing harm my laptop/charger.
