How We Compared These Five
We didn’t put these units on a bench ourselves. This is a specification and feature comparison built from each product’s own Amazon listing — rated and peak watts, tank size, published runtime, receptacle types, and EPA/CARB status — cross-checked against aggregated customer review counts and star ratings. Where a brand publishes a runtime figure, we’ve used their own stated test conditions rather than estimating one, and we’ve flagged below when two brands test at different load points so the numbers aren’t compared unfairly.
Real Math: How Far Does a Tank of Gas Actually Get You?
One number rarely printed clearly in any generator listing is how many hours you actually get per gallon of gas at a realistic load. WEN publishes half-load runtime and tank size for all three of its units in this list, which makes a same-brand, same-test-method comparison possible:
- WEN GN400iM (4,000W): 1.85-gallon tank ÷ 7 hours at half load ≈ 3.78 hours of runtime per gallon
- WEN GN5602X (5,600W): 4.3-gallon tank ÷ 12.5 hours at half load ≈ 2.91 hours per gallon
- WEN DF8000X (8,000W dual fuel): 6.7-gallon tank ÷ 10.5 hours at half load ≈ 1.57 hours per gallon on gasoline
The pattern: WEN’s smallest inverter here stretches a gallon of gas roughly 2.4x longer than its largest dual-fuel unit at the identical half-load test point (3.78 hrs/gal vs. 1.57 hrs/gal). Tank size alone doesn’t tell you how long a full tank lasts — rated wattage against your actual load does. Honda and Westinghouse publish their own runtime figures at a lighter quarter-load (25%) test point instead of half load, so their numbers aren’t directly stackable against WEN’s above, but by their own stated math: the Honda EU2200i covers about 8.5 hours per gallon (0.95 gal → 8.1 hrs) and the Westinghouse iGen2200 covers about 10 hours per gallon (1.2 gal → 12 hrs) — both at that lighter load, which is closer to what a phone charger or a few LED lights actually draws than a full half-load appliance mix.
Which Type Fits Your Situation
Inverter generators (Honda EU2200i, Westinghouse iGen2200, WEN GN400iM) produce cleaner, more stable power with low total harmonic distortion, which matters if you’re charging laptops, running a CPAP machine, or plugging in anything with sensitive electronics. Conventional generators (WEN GN5602X, WEN DF8000X) skip that circuitry, which usually means more raw running watts and a lower cost per watt, but the power quality isn’t guaranteed clean enough for delicate devices without a surge protector in between. Dual-fuel models add propane as a backup fuel source — worth it if your actual outage risk is a gas station running dry, not just the grid going down, since a propane tank doesn’t evaporate or go stale sitting in a garage for a year the way gasoline can.
Final Picks
The All-Rounder Most Households Should Buy
The WEN GN5602X is the pick if you’re not sure yet exactly what you need. At 5,600 starting watts and 4,500 running watts, it covers a refrigerator, sump pump, and a window AC unit running together — headroom most 2,200W inverter units simply don’t have. It ships with both an RV-ready TT-30R outlet and a transfer-switch-ready L5-30R twist-lock receptacle, so it can double as a light whole-circuit backup source if you already have, or plan to add, a manual transfer switch. WEN’s CO Watchdog sensor automatically shuts the unit down if carbon monoxide builds up nearby, and electric start means no cord-pulling in the rain. Owner feedback is consistently positive, with most complaints centered on weight rather than performance.
Skip this if you specifically need pure-sine-wave inverter output for sensitive electronics — WEN doesn’t list this model as an inverter generator the way its own GN400iM or Honda’s EU2200i are, so pair it with a surge protector before plugging in a laptop or medical device.
The Premium Pick With the Deepest Track Record
Honda’s EU2200i has the strongest owner reputation of anything on this list, and it’s the only unit here with a documented runtime table across multiple load points (3.2 hours at rated load, up to 8.1 hours at quarter load) instead of one marketing number. At under 48 lbs and as quiet as 48 dB(A) at light load, it’s built to sit next to a tent or a patio table, not to hide in a garage. The GXR120 commercial-series engine and CO-Minder shutdown sensor are the same components Honda puts in its larger pro-grade units.
Skip this if you need to run more than light-duty essentials — at 2,200 peak / 1,800 rated watts, it won’t start a central air unit or well pump, and it has no transfer-switch or 240V receptacle at all.
The Quietest, Lightest Option for Camping and Tailgating
The Westinghouse iGen2200 undercuts even the Honda on weight at 46 lbs, and Westinghouse quotes a flat 52 dBA noise figure with up to 12 hours of runtime at 25% load from a compact 1.2-gallon tank — quiet enough that most campground noise curfews won’t be an issue. It’s parallel-capable, so two of them can be linked with a Westinghouse parallel cord for more amperage instead of buying one larger unit outright. It’s built to meet EPA and CARB emissions standards, which matters if you’re shopping from a CARB-regulated state.
Skip this if you want a 240V or transfer-switch connection point for home backup — this unit has neither; it’s built for 120V portable use, not panel-tied backup power.
The RV Upgrade With Real Headroom Over a 2,200W Unit
The WEN GN400iM roughly doubles the continuous output of the 2,200W-class units above — 3,500 rated watts, 4,000 surge — while weighing about 30% less than a conventional 4,000-watt generator, per WEN’s own spec sheet. It includes a dedicated 120V RV-ready TT-30R receptacle plus two standard 5-20R outlets, and it produces the same pure-sine-wave output (under 1.2% THD at full load) as WEN’s smaller inverter units, so it stays safe for electronics even at the higher wattage.
Skip this if your RV’s air conditioner needs to start without anything else running — 3,500 rated watts covers one 13,500-BTU RV AC, but there’s limited headroom left for the fridge and microwave to run at the exact same moment.
The Jobsite and Extended-Outage Workhorse
When runtime and raw output matter more than portability, the WEN DF8000X is the outlier here: 8,000 surge / 6,500 running watts on gasoline, or 7,200 surge / 5,850 running watts on propane — useful if gas station access is the actual outage risk in your area, not just the power itself. It’s the only unit on this list with a full 30A 240V transfer-switch-ready L14-30R receptacle alongside its RV-ready TT-30R outlet, and its onboard data meter tracks voltage, frequency, and both session and total runtime.
Skip this if portability is the priority — this is the heaviest, bulkiest unit on this list, and it ships with a wheel kit specifically because you’re not meant to carry it in and out of a truck bed every weekend.

Frequently Asked Questions
How many watts do I need for home backup?
Add up the running watts of what you actually need at once — a fridge (roughly 150-400W running, higher on startup), a sump pump, a few lights, and a window AC unit can realistically total 2,500-4,500 running watts together. That’s why a 4,500W unit like the GN5602X covers more real households than a 1,800W inverter, even though the smaller unit is quieter and cleaner-running.
Do I need an inverter generator, or is a conventional one fine?
If you’re only running lights, tools, and heavy appliances, a conventional generator like the GN5602X or DF8000X is usually more watts for the money. If you’re charging laptops, phones, or medical equipment directly without a separate power conditioner, an inverter’s cleaner sine wave (all three inverter models above are rated under 3% THD, with WEN’s GN400iM under 1.2%) is the safer default.
