Guage required for 50ft extension

I need to connect the 2200i to 50ft extension cable to run fridge/ freezer & tv & some lights from one of the standard plug sockets. What guage extension cord do I need? Can I run second extension cord off the first, or do I need to get another 100ft extension cord for the other plug on the generator so I can also run tv & lights - as circa 50ft away from fridge. Struggling to work this out before I can test generator. Thanking you in advance. Will update rating once I can use generator.

Very quiet and easy to maintan

[This review was collected as part of a promotion.] I’ve been using the iQ3800 for home backup during storms and weekend RV trips—and it’s been outstanding. It kicks out 3,800 starting watts (3,100 running) on gas or 3,420/2,790 on propane, giving me flexibility when fuel is tight. Despite its power, it stays impressively quiet, so I can run it overnight without bothering the neighbors. Built with a rugged steel frame and protected outlets, it’s held up to bumps and rough handling, and the Eco‑Mode™ engine control delivers smooth, efficient performance under varying loads. I love the electric start (with manual backup) and the Smart CO™ shutoff for safety. Routine upkeep is a breeze thanks to tool‑free access to the oil fill and air filter. For reliable, low-noise power and minimal maintenance whenever and wherever I need it, the Generac iQ3800 has been a fantastic, peace-of-mind investment.

Reliable Power, Anywhere You Need It!

[This review was collected as part of a promotion.] The Generac iQ3800 is a game-changer when it comes to portable generators. Whether we’re powering up for a camping trip, a tailgate, or preparing for a hurricane, this unit delivers every time. The dual-fuel feature gives us the flexibility to use gas or propane, which is a huge plus in emergencies. The push-button electric start makes operation completely hassle-free—no pulling cords or guessing. It starts up smoothly every time thanks to the auto-choke and included battery. The LED display is incredibly helpful too; I can clearly see fuel levels and power output at a glance. I also love the Economy Mode—it lets us reduce noise and fuel use when we don’t need full power. The COsense® technology adds peace of mind by alerting us to dangerous carbon monoxide levels. The portability is perfect—built-in handle and never-flat wheels make it easy to move even on uneven terrain. Highly recommend this for anyone who wants reliable, smart power on the go—especially for homes, job sites, and off-grid adventures. 💡🔋⚡

Generly like to power to weight ratio.

I got the generator (Craftsmen 3000i) last spring and used it on two camping trips. It worked flawlessly. However, the last two times I have tried to run the unit it has been very difficult to start. I had to remove the plug and use starter fluid. Yesterday I removed the spark arrestor and discovered it to be quit dirty. I cleaned the spark arrestor and also checked the plug. I installed a hour meter as soon as I got the machine and as of today there are only 38 hours of run time. Even after performing this early maintenance the unit was still hard to start. I really like the weight to power ratio, but am concerned on the starting difficulty.

Best overall but still lacks features

After extensive research I chose this for my RV as a dry camp accessory. It is the best value in inverter generators, but lacks one major feature. No wheels or handles, and there are none available as aftermarket add ons. Very cumbersome to manage without them, since it is quite heavy. Otherwise it has everything I wanted, and is reasonable quiet.

good unit, started first pull out of the box!

It would be usefull to have known the derate info before purchase. The info is on page 5 in the book. 3.5% per 1000ft above sea level is significant at 10,000 ft. If I had known to reduce the expected output by 35% I would have considered a larger unit. I'll still put it to good use and the portability is wonderful.

Excellent product. Better than Honda. More features.

The Generac IQ2000 generator out performs the Honda generator. I love everything about it. After looking on YouTube and the internet I decided to go with the Generac. Price is just right. I am a retired Firefighter and First Responder after 39 years. Used all types of generators in the fire service. Thank you again Generac for a great product. Will use the generator for my personal use during storms, etc.

Awesome Generator

I just purchased this generator because of the size and weight and to run my 13,500 BTU A/C in my pickup camper along with the other items in it and after I got it all full of oil and gas I was taken by the quietness and power. When I turned on the A/C it never fazed it just keep on running as if I had never turned anything on. Its an amazing generator if your in the market..!!

Got it done

I bought the 3000. Lived off it for a few days after hurricane Sally. It powered the full sized refrigerator, an electric cooktop, television, surround sound, phone/laptop chargers throughout the entire power outage. Its easy to carry and surprisingly quiet.

Quiet and Reliable

I was seeing many portable generators and I decided to buy this product because of the power capacity reviews. I bought it and put it to the test with the refrigerator, television and fan and generator went for 9 hrs of usage with 1 gallon. Love it's performance. Recommended
