Ratings & Reviews for Firman Electric Start 4125 Starting / 3300 Running Watt Gas and Propane Dual Fuel Inverter Generator

It's a work horse

I have had mine for 2 years running good only have to change the oil and add gas and still starts first pull and I use it on about 8 house builds a year for site power

Good generator works. Great, but is a lot louder than they say.

Trash

Worked 3 times, then stopped. Firman will make you run around and troubleshoot the issues yourself and give you contradictory instructions. Eventually they will have you take it to a service center where you will find out they have stacks of this same model all which don't work. Firman wont do anything about to offer a soluation like a return authorization to Lowe's, if you purchase the extended warranty through Lowe's, they will tell you to go through Firman instead. $800 Paperweight, that I ...

Garbage- do not buy from Lowe’s.

Won’t hold the load it is designed to hold. Don’t buy from Lowe’s because they don’t honor the 48 hour rule.

Advertises saying runs for 12hrs I got 8hrs

Works great! Only thing is it advertises as running for 12hrs on a full tank that’s false it only ran for about 8hrs till it shutoff with no gas. Other than that it’s great!

Best generator ever purchased

I have had this generator since early 2024 and it has logged hundreds of hours on our off-grid property. I use only high octane fuel and watch the oil level closely. The push button start is so nice. What a great generator!

Runs great, quiet and plenty of power

Fits needs of my RV. Easy start both with electric or pull rope. Runs 15-20 hours a day as I replace propane/electric fridge with a domestic model. Would have given 5 stars. Disapointment comes, as with most everything, .fom the stupid operational design. Firman wants oil checked daily and changed @ every 100 hours. Now go find a phillips head to remove the cover. Why not an easier twist lock 1/4 turn finger lock. While your at it put some teats on the bottom of the access panel so it doesn't s...

Very good but louder than the competition.

I have been full time rving for about 2 years now. 35’ travel trailer with a huge Coleman Mach a/c on top. This generator runs the ac plus the converter, 120v fridge ect all at the same time. The bad reviews seem like a fluke. I just checked i have 750 hours on this unit! I do my maint but not anywhere near what the unit calls for. Its deff robust. My only reason for 4 stars is its not as quiet as it could be. Compared to a eaither of the red units its like a construction site. Not possible t...

So far so good

Used this product once so far. The dual fuel is nice. I plan to use propane when possible so I don’t have to worry about fuel line issues in winter. The wheels are a nice touch to move long distances. At almost 100 pounds it can be loaded by 1 person although 2 is better. The included accessories such as extension cord and cover are nice

The plastic encasement seems very cheap.

My husband was very upset because he paid $850 for a brand new generator that came in with a broken plastic handle. The generator motor and electrical system works well and it starts up our gas dryer with no problem.

Good running Generator

Worked great out of the box. Supports our off-grid cabins with Anker Solix3800. only issue is it kept cutting off for what appears to be no issue? Figured out it was vapor-locking and dying.. Keep the lid partially unscrewed, and no more problems. I get about 2.5hr run time pulling about 2400watts while charging 2 Anker units.

Just what we needed!

The generator works very well, as described. Plenty of power, nice and quiet. Lifestyle item - as the instructions point out, must regularly schedule some runtime, and watch the maintenance interval, so the machine is there and ready when a surprise power outage happens.
