Which device to test start up electrical load to determine genset?

Im trying to determine if a yamaha EF2800i will power my coleman 13500 AC. I don't mind turning off the AC to run something else, but buying a new generator which wont even power my AC would be a expensive lesson.

Is there a device I can plug in between my city power outlet and my trailer which will record peak startup amps when testing? I just cant take the risk of buying to small of a generator, even though the numbers look like they work.

Thanks!

Yes, there is a electrical device available from camping stores. You plug the meter thing into the outlet, then plug the appliance into it. Now all that is left is to turn on the appliance. Instant reading. there is an easier way. read the Air conditioner manual. It will have the amps needed to start and to run. Compare that to the out put of the gen set. My portable Honda 2000 would power my 13,500 air unit. safe travels... ed

That's rated for 20.8A @ 120V. That will run, and should start an AC unit. The breaker is only 20A for the AC anyway.

Yes it looks like the 2800 shouldn't have any problem.. But is the increase from 51.5 - 61 dBA (EF2000iS) to 65 dBA - 68 dBA (EF2800) worth saving about $1000

Isn't the 2800 almost twice as loud as one 2000?

Yes, that is why I bought the Honda 2000. Very quiet. then I bought a larger trailer and had to buy a 2nd unit so I could run both air conditioners. also bought the wiring adapter that allows you to hook them together. safe travels... ed

Thanks Ed. I'm leaning toward a Yamaha and see the EF2400iSHC (53 dBA / 60 dBA) can be paralleled like the Honda's. Maybe I wont need a second with the 2400.. But whats with the Continuous Operation at 1/4 Rated Load at only 8.6 hours??

NOTE: The EF2400iSHC will NOT run most RV a/c units and does NOT have a 30 amp electrical receptacle. YAMAHAGENERATORS.COM DOES NOT RECOMMEND PURCHASING THIS MODEL TO RUN YOUR RV AIR CONDITIONER
Right from your link. However, then in the specs it says it'll run 13.5K BTU ACs, and the 1/4 rated load is different from the Yamaha website.

Yes I saw that.. But after checking the numbers with a clamp on.. (12 amps running and 16 startup) Im confident the EF2400iSHC can do it. I will offer my local dealer $1200.
