I started out with a 300 PSW Inverter which was hardwired into my system and ran extension cord to my Home Entertainment system setup.
We of course liked it so much we kept adding things we want to have ON when camping off the power grid. I eventually ended up with the AIMs PSW 600W Inverter which runs all the things we want to have on when camping off the power grid.
This inverter of course only draws higher current when you add more units to it so that gives us the best of all situations. Being PURE SINE WAVE we do not have to ever worry about what gets plugged into it...
I got my AIMS PSW 600 Watt Inverter from AMAZON $149 and it is on 24/7 when camping off the power grid.
