I have a 12 to 19v adapter made by Tarrus that allows me to plug my Dell laptop into a 12v power. It is more efficient than going to 120vac It was not very expensive . Look at amazon Need to know what power your laptop uses They range from USB-C to (like mine) 19v Robert

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. 73 John Denison KD5YOU On 5/14/2024 8:21 PM, Rudolph Ackerman via BVARC wrote: 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.
