Laptop charger fail.

Because it may be defective or because of "dirty" power?

 

I doubt it, it is a generator that mechanically generates AC current. It does it the old fashioned way by spinning wires around near a magnet to produce "pure sign" AC.... None of that square/stepped wave from typical when converting "AC" from DC.

I don't buy it. Thats what the motor is doing... spinning, an AC generator. I suppose it's possible to screw it up and turn the generated AC into a square wave, but they would have to really try intentionally to do that, and it would end up requiring more hardware to do it. Why?

 

I know the multi-meter was around here somewhere....

Whats this? Ohhh ,mmmm, Beer.

 

I asked no such thing. I asked what was a recommended variable power supply. I got this instead.....

Even if the generator isn't virgin clean it's good enough, unless it's defective and out of parameters. I've used the crap inverters in the truck without an issue, my last laptop charger didn't have issues with this generator, which is the charger I'm using now. The first charger I had issues with developed problem from household AC current. They are just cheap and I'm looking for another option.

 

Maybe, it's a "gaming laptop" and wants a bit of juice. 19.5v 10.3 amps 200W.
I'm not in a truck right now (almost an RV, on vacation) and just the CB will drain the singe battery fast enough. I use a "battery minder" when the generator is running but it isn't enough to keep up. just a barefoot CB.

I'd like to put a bank of batteries in between the frame rail, but that will probably wait until the snow starts to fly again and I pass though Las Vegas on the way back south. Probably find a cheap wire feed welder at a pawn shop there.
