Perfect for us!

I live in Florida in an area with alot of construction. So we have not only hurricanes and storms, but accidents and other power outages. Mines set up for whole house and with the soft start AC I can run everything, including my water well. I work for emergency services so in a disaster I'm away for days and I trust my family with this unit. Highly recommend.

Verified Purchase:Yes
I've been a DuroMax customer for over 10 years and previously owned an XP4400EH, which proved to be an extremely reliable generator throughout its life. That positive experience is the primary reason I chose the XP11000iH ("Big Red") over other brands when it came time to upgrade.
So far, I'm very impressed with the build quality, features, and performance. The generator has operated smoothly, starts easily, and gives me confidence that it can handle my home's backup power needs during outages.
The only reason I'm not giving it 5 stars yet is that I simply haven't owned it long enough to fully test its capabilities or establish the same level of long-term reliability that I experienced with my XP4400EH. Reliability is earned over time, and DuroMax has set a high bar based on my previous experience.
If Big Red proves to be as dependable as my XP4400EH was over the next several years, I would have no problem updating this to a 5-star review.
Highly recommended based on my experience with the brand and my initial impressions of this generator.

Opened box 2 days ago and added oil for initial run. The oil inlet cap is 100% blocked by a bundle of wires. Was a battle to get right amount of oil in. Not looking forward to next oil change. Why build a great generator and ruin it by a needless oil access design?
No, I would not recommend this to a friend.

Poor oil system fill design

Access up the oil plug is a booger. Difficult to remove the fill plug due to the wire harness placement. Otherwise generator is ok.
No, I would not recommend this to a friend.

Nice Generator
on July 13, 2026
Posted by: GKF
I purchased this because I needed a bigger generator and this fit what power was needed. I haven't had it long but have some initial impressions. It's way nicer than my old generator. I was expecting some assembly and there was none. Just connected the battery and added oil. It started up and ran like a champ. Easy to move for storage. It even looks good. The 4 stars are because the placement of the oil fill cap. The maintenance panel is low, and the oil fill cap was behind a wire bundle. It's difficult to see and was hard to get my hands on. Checking oil level before each use is going to be less than easy. The generator comes with some tools and other extras. Haven't tried the key fob yet, but overall happy with the purchase.

Great Generator with a few exceptions

Generator is well built and comes with a lot of accessories. Changing and adding oil need to be more user friendly.

Pretty Impressed

I bought the 11k 2 years ago. I use the propane feature, handles everything as advertised.
The fear I had was was it going to start? Is the trickle charging getting it done? My machine cranked right up, ran smooth, performed like a dream. Confidence with my product. Ready for the next "well crap" from my wife.
