Pretty good but seems to need high octane fuel
Initially I was extremely pleased with the GP2500i portable inverter generator during my first 5 day outage in June 2026. It was relatively easy to start and I used it to recharge my lithium power supplies which were supporting my essentials (fridge, sump pump, a few lights). Then in August we had an 11 day outage due to a derecho resulting in a multiple county widespread damage and power loss. It worked fine for a couple days but then started struggling, even shutting down. Oil was fine, cap was not so tight as to restrict gas flow. We poured out the gas and filled with fresh; no improvement. I was using regular gas, 87 octane with 10% ethanol. Non-ethanol gas was not available. Additives to address possible moisture may have helped a bit but not enough. I finally switched to highest 97 octane/10% ethanol fuel which did the trick and the generator ran reliably. So in future when needed I will use high octane gas.

electric starter and pull start combo, ease of use
before I purchased your product, I did my homework.
it filled my needs of an inverter.
not to much but just what I need for my purpose.
it exceeded my expectations. the dual fuel, and the whispering sound!! awesome product

Great features compared to other generators
I’m 70 years old and live alone. When I purchased this product generators were in very high demand due to frequent power outages and severe storms. It was the only one I could find. There’s no doubt that it’s a wonderful product, but it’s too heavy for me, and I don’t have the upper body strength to start it with the pull cord. I need to find a neighbor to help, usually during driving rain and terrible weather conditions-not ideal times to ask for help when neighbors were experiencing similar struggles.
