saygudday - i've had this basically
cheap square wave
inverter for at least seven years now and i've yet to find anything it can't run. i've used it on the 600 watt shop vac,
power drill, dremel tool, flat
screen tv, tv signal booster, fans, and computer. probably more i can't remember.
if you're just
charging small
batteries like in your
vhf or
electric shaver or such, i find a small
inverter of maybe 100 watts or less is a better idea. you don't lose as many amps to inefficiency with the smaller inverter. i hook mine up to a cigarette lighter
plug wired off the 12 volt panel.
