Small AC motors and Inverters
Disappointed that my ancient Mod Sine Wave inverter (140W cont, 200W surge) shuts down with a 120W coffee grinder. Works ok with the 400W (cont) MSW inverter built-into the truck, though a little ...

Modified Sine inverters are dirty power. The voltage is erratic and as a HIGH chance of damaging sensitive electronics.
The cost of a Pure Sine inverter is well worth the cost of replacing a Mac's power board, or that neat cordless drill charger you had....had.... had...

It explains visually and audibly why a non PS inverter should NOT be used.
While the inverter needs thick wires and close to the batteries, the 120v output does not. You can run a normal extension cord where ever you need it.
My PS inverter has three 120 plugs. I wired them with household wire and installed plugs inside the camper.
I made a plug system/switch so that the microwave can be used off the inverter, but not energize the whole camper.
Most PS inverters also have remote power on abilities. This allows you to turn it on inside the camper easily.
