At full load no, of course not - no 1000 watt inverter that's looking for ~ 80 amps at full load will work from a cigarette lighter receptacle that at best if probably rated for ~ 7 amps. :R

pt you are a laugh riot, and I mean that in a nice way.

what is up with these double posts? I know I didn't push the enter button twice? am I the only one getting double posts?

A while back I was wondering why even the little 400w cheapie I have only comes with a lighter plug. What good is 400w when the fuse and wiring are only 10-15 amps.

Isn't it obvious? ... more sold because of perceived ease of use by those who haven't got the faintest idea that this arrangement is nowhere near suitable for an inverter of that size. :R

Puzzles me.
Better brands don't usually do this, but a cheaper no-name baby cobbled up in China could have anything, including inability to run loads over 180W with "400W" written all over, so it could have a cig plug as well. Too bad that Xantrex has gone this way too - after changing the ownership and nationality.

Hi,

I've run my 400 watt MSW inverter from cigarette plug outlets successfully since 2000. Just once I blew a fuse because I placed an 800 watt load on the inverter by accident.

It would be extremely inconvenient for me to add the wire needed to run 100 amps of power to where I wish to use the inverter. I already have a 3000 watt properly installed and up to code. But I don't wish to run a 50 watt load on it--there is too much overhead.

It would simplify my life to carry 2 inverters instead of 3--and PSW is preferable.

I wanted to know if the inrush surge on the 1000 watt inverter would pop the 15 amp fuse. Does anyone have that information?

Don, did you blow a fuse in the 400W inverter (with 800W load) or in the cig receptacle?

at what load, how many watts ? what item/device

you don't normally have an inrush on say an electric heating element
but you would on a large fan or say a small compressor fridge
my fridge draws 90>100 watts running, but has a 900w surge, almost 70 amps into the inverter

another problem is say a switching power supply for digital controled electric blanket

avg power use is quite low, but the peaks are relatively high
it only draws power thru part of the sinewave cycle, makeing avg use low, but the actual amps flow higer

Hi Almot,

In the fuse panel of the RV. Inverter was fine.
