I have a 2010 450h. Want to run a very small Remington Limb N Trim electric chainsaw from the vehicle ac outlet. The chainsaw draws 8 amps,but does not state any wattage. The car outlet is rated for 100watts. I have no idea what kind of watts the chainsaw draws. Do I run a risk of damage to the ac inverter in the car, or will it simply trip the switch if there is an overload?

 

V*A=W so (120V)*(8A)=960W

Honestly not sure if the inverter has a cutoff or safety built in, and personally, I would not test it with the chainsaw.

 

First off welcome. To add to tus' comment, you'd probably blow the fuse. If your RX's AC outlet is 100 Watts, the 100W/120V yields a 0.833 amp rating. I would not connect it

 

In support:

 

Thanks for all the responses. Good input - I will not attempt to run my chainsaw from the car!

 

Anyone may be tempted due to the capacity of the traction battery.

Typically hand held electronics is what the plug supports. These days laptops can draw near the max ratings. I would not consider anything else, the list of NOT to use items includes microwaves, coffee maker, toaster, iron and machinery for yard use. [not a camping friendly machine].

You'll need to hardwire a very powerful DC-AC inverter to the 12V battery.
Something along these lines, judging by the 8 amp requirement at 120V (1000WT):

I figure our traction battery and inverter are good for 100 amps at 12V. That will produce ~ 1200WT.

If course, this being a chain saw, I'd be very wary of constant draw changes due to its workload type.
A fridge or a TV may be fine, but something this peaky has potential to do a lot of damage.
Good 'ol gas chainsaw would be a much cheaper alternative.
