You can only _continuously_ draw 80% of the maximum amperage out of any
household circuit. (The wiring over heats.)
Since a large fraction of 115 volt outlets have a 15 amp breaker, (some
have a 20 amp) you can only draw 15 x 115 x 0.8 = 1380 watts.
On a 20 amp, 20 x 115 x 0.8 = 1840 watts.
For a limited duty cycle (short time) you can draw the full amperage,
but only for a very limited time.
That is why every 115v heater that you can buy in the store is rated at
1600 watts, at the very most.
Doesn't matter how big or how fancy or how much they cost, they all are
limited to 1600 watt output.

Hi all.
question for the EV connoiseurs out there:
I have a 2013 Nissan Leaf with a ChaDeMo port. Are there any
portable V2G units that can plug in and provide 2KW of power?
Alternately, are there any other EVs that support such a thing?
I saw such a thing at a Nissan booth at a recent event.

but it didn't look like it was aimed at mobile use.
And evidently they have a new system which would meet my needs:

but it's only available in Japan for now.
The application is a bounce house at a green fair; evidently those
need 2KW during inflation, and 1KW during operation
( see

).
Thanks,
Dan
