Is it safe for me to connect my laptop computer (IMac) to a power inverter inside my car?
I want to keep my computer alive for a 4 hour trip, and we have a DC/AC Power Inverter, but I’m not sure if it is safe to connect my computer to the car’s battery through the power inverter.. and advice?
sure just don’t skimp on the inverter
