Question about Sine Inverters
Hi, I am John and new to the forums.
I've got a question about inverters. I've got one that, when I plug it into my cigarette lighter in the back of my Eurovan (which comes off the beefier shore battery), makes those telltale sounds that I am told occur with a pure sine wave adapter when you are trying to charge certain bigger appliances (a laptop in my case). And, it doesn't really seem to charge the laptop.
However, when I plug the inverter into the cigaretter lighter on the dash and try to charge my laptop, everything goes well. It charges and doesn't make any sounds.
What does this mean and how should I set myself up so that I can charge the laptop when the van's not running!
thanks,
John
