Champion Power Equipment is a North American outdoor power equipment company that built its reputation on generators, and it is one of the few brands that sells across the entire range: tiny inverter units you can carry with one hand, mid-size and large portables for home backup, and permanently installed whole-house standby systems with their own automatic transfer switches. The brand is widely associated with dual-fuel designs, long standard warranty coverage and free lifetime technical support as stated in the listings.
This guide covers six Champion models that a homeowner shopping for backup power in 2026 is likely to run into. It explains how the lineup is organized, what each model actually is, who each one fits, and the installation and safety requirements that come with gas-fired and gasoline-fired generators. All specifications below come from the Amazon product listings for these models (retrieved October 2026) and may differ from Champion’s current spec sheets, so confirm details with Champion or the seller before buying; nothing here is a test result or a performance promise.
How the Champion lineup is organized
Champion’s generator catalog splits into two fundamentally different categories, and choosing between them is the first real decision a homeowner makes.
Home standby generators are permanently installed outside the house on a pad, wired into the electrical system through an automatic transfer switch, and fed by a propane tank or a natural gas line. They start themselves when utility power drops and shut down when it returns, with no refueling, no manual operation and no extension cords. The two standby systems in this guide include a 200-amp automatic transfer switch, and they carry a 10-year limited warranty. Two switch platforms appear in this lineup: the aXis transfer switch on the 14kW system, which offers Wi-Fi setup and manages high-demand loads across four priority levels, and fleX Technology on the 22kW system, which uses Power Line Carrier communication to cut wiring between the generator and the switch. Both standby units use a 24-volt starting system rated to operate down to -22 degrees F, and both perform self-diagnostic tests; the 14kW listing specifically states no cold weather kit is needed between -22 and 104 degrees F.
Portable inverter generators are the other half of the lineup. These are wheeled or carried units that produce inverter-conditioned power, meaning the output is clean enough for sensitive electronics. Champion’s portables in this guide all include the CO Shield carbon monoxide auto shutoff system, which stops the engine if it detects a dangerous CO buildup, plus a 3-year limited warranty. Within the portables, there are two sizes that matter: the 11,000-watt class, which is large enough to back up a meaningful slice of a house through a transfer switch or interlock, and the 2500-watt class, which is sized for a handful of essentials, camping or tailgating.
Cutting across both categories is fuel flexibility. A dual fuel model runs on two fuels, a tri fuel model on three. That flexibility is one of the clearest reasons homeowners end up on Champion’s shortlist, because it decouples the purchase from a single fuel supply chain.
The models worth knowing
Champion 22,000-Watt Dual Fuel Home Standby Generator with 200-Amp Automatic Transfer Switch and fleX Technology
This is the largest unit in the group and the one aimed at genuine whole-house coverage. It delivers 22,000 watts of continuous power on liquid propane and 19,800 watts on natural gas, paired with a 200-amp automatic transfer switch. The fleX Technology platform uses Power Line Carrier communication, which Champion says means less wiring between the generator and the switch; actual installation scope and cost depend on the site and the installer. It is designed to manage high-demand appliances so that not every large load needs to run at once, and a licensed electrician’s load calculation determines whether that is sufficient for a given home.
Champion rates it at 67 dBA, the result of advanced sound dampening and a low-tone muffler, and houses it in a fully aluminum enclosure for weatherproofing and oxidation resistance. The 24-volt starting system is rated to -22 degrees F. It is aimed at larger homes, including households with multiple air conditioning zones, well pumps or electric water heating, and at owners who want whole-house coverage rather than a selected circuit list; whether 22kW is enough for a particular home depends on a load calculation by a licensed electrician. It includes a 10-year limited warranty with free lifetime technical support.

Champion Power Equipment 100837 14kW Home Standby Generator System with 200-Amp aXis Automatic Transfer Switch
The 100837 is the mid-size standby option: 14,000 watts of continuous power on propane and 12,500 watts on natural gas, bundled with the aXis ATS200 whole-house automatic transfer switch. The aXis switch sets up over Wi-Fi and can manage an unlimited number of high-demand loads using four priority levels, which is intended to let a 14kW generator serve a house whose connected loads would otherwise exceed its raw output, subject to a proper load calculation. Champion describes it as quietest-in-class at 62 dBA.
Like the 22kW unit, it uses a 24-volt starting system; the listing rates it between -22 and 104 degrees F with no cold weather kit required, and it performs customizable self-diagnostic tests, and carries a 10-year limited warranty with free lifetime technical support. It is aimed at small and mid-size homes, or larger homes where load management is acceptable (confirm sizing with a licensed electrician) and the goal is automatic operation at a smaller footprint than a 22kW machine.

Champion 11,000-Watt Remote Start Tri Fuel Portable Inverter Generator
This is the most flexible portable in the lineup. It runs on gasoline, propane or natural gas, and both the LP and NG hoses are included so it is ready for any of the three out of the box. Output varies by fuel: 11,000 starting watts across the board, with 9,000 running watts on gasoline, 8,100 on propane and 7,290 on natural gas. That tiered output is normal for multi-fuel engines and is worth planning around, because your running-watt budget shrinks as you move from gasoline toward natural gas.
The outlet panel includes two 120V 20A GFCI household duplex outlets, a 120/240V 30A locking outlet, a 120/240V 37.5A outlet and a 12V automotive-style outlet. A wireless remote key fob starts and stops the unit from up to 80 feet away, and CO Shield is standard. It fits homeowners who want serious backup capacity without a permanent installation, and especially those with an existing natural gas supply for long outages plus gasoline or propane as a fallback; any permanent natural gas connection should be made by a licensed gas fitter or plumber in line with local code. Warranty is 3 years limited with free lifetime technical support.

Champion 11,000-Watt Wireless Remote Start Portable Inverter Generator
This is the gasoline-only sibling of the tri fuel model, with the same 11,000 starting watts and 9,000 running watts and the same outlet set: two 120V 20A GFCI duplex outlets, a 120/240V 30A locking outlet, a 120/240V 37.5A outlet and a 12V automotive-style outlet. Champion lists up to 15 hours of run time on a full tank of gasoline and a noise level of 64 dBA from 23 feet.
It uses a 459cc Champion engine with battery-included electric start and built-in Cold Start Technology for cold-weather starting, plus the same 80-foot wireless remote and CO Shield shutoff. The trade-off against the tri fuel version is straightforward: you give up fuel options and gain a simpler single-fuel machine at full gasoline output. It fits households that store gasoline reliably and want maximum running watts from a portable. Warranty is 3 years limited with free lifetime technical support.

How to choose
Start with the load list, not the model. Write down what must run during an outage and whether any of it is 240-volt: well pump, central air, electric range, electric water heater. A 2500-watt inverter can typically run a refrigerator, lights, electronics and a modem, provided the refrigerator’s startup surge fits within the rating. An 11,000-watt portable can often cover those plus a well pump or a window unit, depending on each appliance’s starting watts and on a connection installed by a licensed electrician. Whole-house operation with central air and multiple large appliances is standby territory. Running the numbers first is the single most useful step, and the generator size calculator walks through the starting and running watt math.
Then decide automatic versus manual. Standby systems matter most where outages are frequent, long, or likely to happen while nobody is home: a 14kW or 22kW Champion with its 200-amp transfer switch restores power without anyone touching it, and the load-management features on aXis and fleX are designed to let a 14kW unit serve more of a house than its raw output alone suggests. A portable requires someone present to fuel it, start it and connect it, which is a real limitation in winter storms. For that side of the decision, see the guide to portable generators for winter outages.
Match the fuel to what your property actually has. A natural gas meter can make the tri fuel portable and either standby unit more practical because fuel does not need to be hauled, though gas supply capacity must be verified by the installer or utility and gas service can occasionally be interrupted during major events. Propane suits rural properties with a tank already on site. Gasoline-only models are the simplest to operate until a multi-day outage makes station access the problem. Note again that running watts drop as you move from gasoline to propane to natural gas on multi-fuel units.
Weigh timing and the wider system. Standby installations involve a licensed installer and permits, so lead times stretch before storm season; the guide on when to buy a whole-house generator covers that cycle. If you are comparing standby platforms across manufacturers, the standby generator brand comparison puts Champion alongside the other major names, and the whole-home resilience guide covers how backup power interacts with water and HVAC.
Installation and safety
Carbon monoxide is the primary hazard with every portable model here. Run portable generators outdoors only, well away from doors, windows, vents and crawlspace openings, and never in a garage, carport, shed or breezeway, even with the door open. Install working CO alarms on every level of the house and test them. Champion’s CO Shield auto shutoff is a backstop, not a substitute for correct placement.
Portable generators must never be plugged into a wall outlet or wired directly into the panel. Backfeeding energizes utility lines and endangers line workers and household occupants. Connecting any portable to home wiring requires a manual transfer switch or a listed breaker interlock installed by a licensed electrician in accordance with local code. Without that, use outdoor-rated extension cords sized for the load directly to appliances.
Home standby installation is not a DIY project. The 14kW and 22kW systems require a licensed installer and, in nearly all jurisdictions, electrical and mechanical permits with inspection. Gas line sizing must be verified for the unit’s demand, because an undersized line starves the engine, and propane or natural gas connections, regulator selection, exhaust clearances and setback distances from windows and combustible walls must all follow the manufacturer’s instructions and local code. Siting also has to account for pad requirements and drainage. Propane tank size determines how long a standby unit can run, and natural gas supply capacity and meter requirements vary, so ask the installer and your gas utility or propane supplier to confirm. Local noise ordinances, setback rules and HOA requirements may also apply. Standby exhaust contains carbon monoxide too, so keep working CO alarms in the home even with a standby system.
Treat fuel and maintenance as part of ownership. Store gasoline in approved containers away from the house and never refuel a hot or running engine. Standby units need their scheduled oil, filter and battery service to be ready when called on, and the self-diagnostic tests should be allowed to run. Warranty coverage stated above is the manufacturer’s limited warranty as listed; terms, registration requirements and exclusions come from Champion.
Frequently asked questions
What is the difference between dual fuel and tri fuel on Champion generators?
Dual fuel models run on two fuels. The 2500-watt dual fuel inverter operates on gasoline or propane, and the standby units operate on liquid propane or natural gas. Tri fuel adds a third option: the 11,000-watt tri fuel portable runs on gasoline, propane or natural gas, with both hoses included. Output is not identical across fuels. On the tri fuel unit, running watts are 9,000 on gasoline, 8,100 on propane and 7,290 on natural gas, so size the generator for the fuel you expect to use most.
What does the automatic transfer switch included with a standby generator do?
The transfer switch is the device that disconnects the house from the utility and connects it to the generator, then reverses that when utility power returns. Both Champion standby systems in this guide include a 200-amp whole-house automatic transfer switch. The aXis ATS200 on the 14kW system sets up over Wi-Fi and manages high-demand loads using four priority levels; the fleX system on the 22kW uses Power Line Carrier technology to reduce wiring between generator and switch while managing high-demand appliances. Load management is what allows a generator to serve large loads without running them all simultaneously.
How loud are these generators in a residential setting?
Champion publishes figures for each model. The 14kW standby is rated 62 dBA and the 22kW standby 67 dBA, both using sound dampening and a low-tone muffler. Among portables, the 11,000-watt gasoline inverter is rated 64 dBA from 23 feet and both 2500-watt inverters are rated 53 dBA from 23 feet. Decibel ratings are measured at a stated distance under specified conditions, so real-world perception depends on placement, hard surfaces nearby and how much load the engine is carrying.
Which Champion models work for a multi-day outage?
Automatic operation and an uninterrupted fuel supply are what matter over several days, which favors the 14kW or 22kW standby systems connected to natural gas or a large propane tank, since they start automatically and, on a natural gas supply, need no manual refueling (propane systems run only as long as the tank supply lasts). Among portables, the tri fuel 11,000-watt unit is the strongest candidate because a natural gas connection, where available and installed by a licensed professional, reduces refueling trips, while gasoline-only units depend on stored fuel and station availability. For a structured comparison of approaches, see the guide to the best backup power for a 3-day outage.
