So I got this last year with the Home Depot price match. I bought it specifically to run our 30A trailer. I did the 5-10 hour run, drain oil thing as was recommended.

I basically used this once, and it said I was over using it (correct term is overloaded I guess), so it cut supplying power to the trailer even though it was running.

Never used it again, searched online what the issue could be, but no luck.

Anyone else have this issue? I have read online and reviews how this will power a trailer with AC with no issues, but yet it won't for me (I only have a 13,000 AC not 15,000). All we were running was AC, nothing else.

It seems to run fine when nothing is plugged in, it's quiet, maybe I am doing something wrong, but I just don;t see how, it's basically plug the 30A cable in.

I can't say for sure how hot it was outside that day, but I don't think it was over 25C
Got mine from Costco last summer, we have a 13,000 btu roof AC, it will run both the AC and the microwave at the same time I'm sure. Maybe you got a bad unit? Maybe check if your choke cable is properly attached...there are a few videos on youtube about it being loose right from the factory. Could definately cause a power issue. Loose choke video

Just ordered one through Home Depot with price match. Came to $610.20 (Ontario) delivered to my door.

Reviews look pretty good, and at this price it was a no brainer for me.

For how long am I covered by Costco returns? Say in a year and a half it doesn't work anymore will they take it back?

Chat with Costco Rep:

"Costco does have a very good return policy -
we will typically accept returns within the first year of owning the
product. After that one year, we would look at it case by case for
a return."

"If anything goes wrong with the item within 3 years I simply bring it back to Costco?"

"As it would have a Warranty, you can reach out
to the Vendor for assistance and they will be able to help you
under the warranty. If you wish not to reach out to the Vendor,
Costco may do so for you!"

This is how I’ve understood it. After a year they expect the manufacturer to take care of you. But if they do not (say they refuse to repair or it’s somehow not possible) then Costco would likely return it.

I did that with one product several years ago. I had it over a year, the manufacturer replaced a part that kept breaking several times. Then they said it was ‘normal’ (which it wasn’t) and refused to take care of it under warranty. When I went back to Costco with it they refunded no issue after I told them the situation.

I don't know much about generators but did you ever shut it off or let it run out of fuel while a load was still connected? I read that can damage a generator, I'm not sure how you test for it though? Maybe connect a load (blow dryer/space heater) and measure the voltage output. Not sure if you followed the break in instructions, I think you're only supposed to put less than 50% load for the first while.

You could ask @TomLafinsky, he was commenting in one of the other threads and seemed to know a lot about generators.

Never, this was on first tank, I had barely used it before except for the 5 hour burn in and change of oil.

I might have used it an hour, and it was low draw (using it to power some tools while building a deck.

Thanks for the info, that was great of you.

I did order one from Costco 2 days ago and today got an email that it has shipped. Just looking to use it when I am camping in public land.

I've know my way around camping, never needed electricity. However, with a baby, I just wanna be prepared. but if it makes a ton of noise, then i will probably try and "steal" some electricity during the day from washrooms to charge my batteries... I have a couple 5 amp chargers, should make quick work charging them back up
I don't know what your set-up is, but have you considered using a solar panel? I added a 100 watt solar panel (and a controller); probably cost me $300 all in (I installed) and on most days I get 4-5 amps coming out continuously.

My 1700/2100w firman can run a 13000 btu ac alone. Something wrong with your unit.

Or possibly your AC current draw on startup is monstrous. Startup amps are usually 2x the normal running amps.

At this point I would suggest getting a kill-a-watt. You will need two devices/tools like an electric heater, a hair drier, an electric iron, a drill, etc.

Start your gen and let it warm up for 2-3 minutes. Then connect kill-a-watt to gen and connect the first tool/device you found that consumes around 1500 watts into the kill-a-watt. Turn it on and then use the kill-a-watt to find out the exact number of watts used by your first tool/device.

Unplug the first tool/device from the kill-a-watt and plug your second tool/device in the kill-a-watt and turn it on to find out how many watts your second tool/device is consuming.

Ideally the total consumption of both tools/devices should be close to but not over 3000 watts.

Unplug kill-a-watt from gen and then plug your two tools/devices into the gen. Turn the first one on, wait a few seconds and then turn on the second one.

If your gen can run both then there is nothing wrong with your gen.

Btw, you said you used it to build a deck. Electric motors from tools like saw can require up to 2 to 3 times their rated amps/watts. Always take that into consideration when connection something to the gen.

A gen will survive a certain number of overloading. But eventually you can kill the gen by simply burning a $2 component of the gen's electronic board. What is even more dangerous is letting it run out of gas while a device/tool is connected to the gen AND pulling electricity out of the gen. Doing this a certain number of times is guaranteed to eventually kill the gen. But sometimes a single time is enough to kill the gen.
Physical pride is amusing. Mental pride can be annoying. But spiritual pride can be dangerous.

I will try this when I get back to the trailer. Thanks for your help.

I used it to plug in the battery chargers for the power tools, the only other thing maybe was a chop saw, but I can't remember to be truthful.
