PowerSmart 2500-Watt Portable Gas Inverter Generator, Super Quiet, High Fuel-Efficient Generator, Lightweight, EPA Compliant 2025

Great little generator. Powers our mini fridge in our farmstand all day while on eco mode and doesn’t run out of fuel. About 12 hours of run time on a full tank (1gallon non ethanol gas). It’s also very quiet and can you barely hear it 20 feet away which is nice for the farmstand vibe.

I got my generator yesterday. They are NOT shipped with oil (I knew this, but everyone doesn't). I couldn't find the spec for it online, so I waited for the unit and the owners manual to show up. Here's the information that I wished I could have found so I could have ordered everything all at once: At normal temps, you will need 16.9oz of 10w-30 4-cycle oil to fill it. It did come with a nice little funnel to add the oil. At cold temps (below 25 deg F) use 5w-30. Over 80 degrees F regular temps, use 30 weight. I'm not sure when I'll be using mine, so I've got the 10w-30 on order. Oil should be changed after the first 10 hours of use, then every 6 months or 100 hours of use. The spark plug should be replaced every year or 300 hours of use. I found a part # in the owners manual (100009386) which I think is a Champion L95YC plug (I found it via a Google cross-reference, so I'm not 100% sure)... I haven't confirmed that yet, but I bought 2 of those and will compare. The manual specifies gap 0.6-0.8mm (0.024-0.031 in) tightened to 10-20Nm torque (it comes with a plug wrench). There is a washable air filter in the unit, clean every 3 months or 50 hours of use. Wash it in liquid detergent (ex: Dawn dishwashing liquid), rinse thoroughly, wring out in towel to dry, pour engine oil over filter, work oil through filter, squeeze in paper towel to remove excess oil, re-install. I tend to keep gasoline (I buy premium from a good gas station like Shell/Chevron) in my garage for a year. I use Stabil gas treatment in it to keep it fresh and, every spring (spring cleanout), if I haven't used it I'll pour the gas into one of our cars and buy fresh. NOTE: The gas storage/quality/stabil tips are mine... the manual says to use regular gasoline of 87 Octane or better. -------------------- My oil arrived yesterday. I added the 16.9oz of 10w-30 4-cycle oil I bought (branded Generac) and a bit of fuel (93 octane w/ Stabil added for longevity). Gas cap vent open... choke out... red fuel valve to open... one gentle pull and the engine starts right up. I slid the choke in and it purred beautifully... even quieter than the Yamaha suitcase style that I had years ago (and sold with a trailer) that was supposed to be the quietest in the class. I'm very happy so far!

I rarely leave product reviews however I always read reviews before making an expensive purchase. I took the family on a 10-day camping trip at a very popular state park where generators are not allowed during quiet hours at 10 pm. This generator was quiet enough so it would not be noticeable unless you were standing under 75 feet from our campsite. When I first got the generator I gassed it up with super unleaded and premium oil and ran it for 10 hours to break it in. The generator started on the first pull and all was well. I changed the oil and went on the trip. After the first few days of running the generator for 15 hours a day, I ran out of gas in my can. The generator would run around 10 hours on economy mode only running 6 fans and some cell phone charging stations. Well, I went to refill my gas can and because where we were I bought regular unleaded because the price for super unleaded was super high. This was my demise. That night the generator would run an hour and shut off, then another two hours and shut off. I was super frustrated and ready for my money back. The next day I thought maybe I should try to change the oil again. It didn't help the same problem with shutting off after an hour or two. On the 5th day of my trip, I figured why not drain the gas and go back to super unleaded. Well, surprise surprise, the little sucker is bougee and only wants high octane fuel. I never had a problem for the reminding 5 days. Ran like a champ. I have now almost 200 hours running it. So, with good high octane gas and changing the oil often this is an awesome buy.

Great back up generator

So, I purchased this generator 4 months ago. I finally used it for my first tailgating opportunity and it was only running one 24 inch TV. After about 5 hours it started shutting down. After restart it would shut down again in 10 minutes with the overload light flashing red as it shut down. When I called Amerisuninc on September 7th to ask them about this problem, I was told that running it for 5 hours was a long time and that I shouldn’t run it so long as it gets hot. Really? It’s a generator and many generators around me on the same day I was tailgating ran for 10 hours or more with no issues. So, if my power goes out and I wanted to run my refrigerator, I better tell the power company that I only have 5 hours and they need to have my power back up by then. What a joke, I have never heard a manufacturer say that about their product - in this case a 2200W generator. Worse response ever and worse product I have ever bought. Please get a Ryobi, or Honda, or some other more reputable brand than Amerisuninc. I would like my money back as no where in their brochure or in the description do they ever mention this limitation. The brochure even says at 1/4 load it can run for 10.5 hours. Go figure, that’s a straight up lie! This happened again with using it outside to run my electric chainsaw. After running it for a few hours (on and off) it started shutting down again. It is truly a worthless generator.

I bought the PowerSmart 4800-watt portable inverter specifically for camping, and so far, it’s been a great investment. I used it during a week-long camping trip and didn’t encounter a single issue. It ran smoothly the entire time, powering everything I needed without any problems. It’s compact enough to transport easily but powerful enough to handle multiple devices. I appreciate the quiet operation and efficiency it definitely gave me peace of mind throughout the trip. Highly recommend for anyone looking for a dependable power source for outdoor adventures!

I haven't given the product a good test yet, but I want to review the customer service of the seller, Amerisun Inc. I submitted my Amazon invoice to our power company for a rebate through a program they offer. The power company of course rejected our request, saying our invoice from Amazon was not sufficient because it did not include the model #. I contacted the seller and they replied within a day with exactly what we needed to satisfy the power company bean counters. Thank you for the quick and helpful reply.

This has been a reliable trusty generator. Well worth the money.

Excellent unit quite.....once I put oil and fuel into generator ,it starred on first pull ..lots of power for what I need while camping in my trailer
