When the lights go out at dinner time and the fridge, the phones and the router all go dark together, a best inverter generator is the backup that keeps the essentials running without the roar of a jobsite unit. We compared inverter generators ranging from a high-output open frame unit to compact camping-size models, on stated watts, run time, outlets, noise and warranty. Fuel generators run outdoors only, far from doors and windows, because of carbon monoxide.

Detailed Review
The listing states 7600 running watts and 10000 peak watts at less than 3% THD, remote electric start with an included key fob, push button and recoil start, and up to 12 hours of run time on a 5.28 gallon fuel tank with a fuel gauge.

Coverage is a 3-year limited service, labor and parts term with a nationwide customer service network.
Who it's for: buyers who want high output, remote start and transfer-switch-ready outlets for home backup. Who should skip it: anyone who needs a light unit to carry, since this one lists 147.7 pounds.
Its Solar Score of 9.7/10 comes from performance 32/35, build 21/25, value 21/25, safety 8/10 and warranty 4/5: 86 of 100 points, placed on our 9.2 to 9.8 scale.

Safety and Warranty
What this listing states. CO sensor, GFCI outlets with rubber covers and automatic low oil shutdown, so safety scores 8 of 10. 3 Year Limited Warranty. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 4 of 5. See How We Pick.
Inverter limits. Stay within the stated continuous watts (surge watts last only a moment), use the cable size and fuse the manual gives, ventilate it, and never connect an inverter to home wiring yourself; that is work for a licensed electrician.

Honda EU2200i
A 2200-watt inverter generator that lists 48 to 57 dB(A), app control over Bluetooth and a 3-year residential warranty.
Pros
- 48 to 57 dB(A) noise range stated, below a normal conversation per the listing
- My Generator app with Bluetooth for remote operation and service reminders
- Eco Throttle System listed for fuel efficiency on a 0.95 gallon tank
- CO-MINDER automatic shutdown on high carbon monoxide levels stated
Cons
- Bullet and spec table weights differ: just over 47 pounds against 51.0 pounds
- Not available in California, per the listing note
- No 240V outlet stated in the listing
- No USB outlet stated in the listing
Detailed Review
The listing states 2200 watts, 120V output, 48 to 57 dB(A), a 0.95 gallon tank with 3.2 to 8.1 hours of run time, an Eco Throttle System, the My Generator app over Bluetooth with wireless stop and service reminders, CO-MINDER carbon monoxide detection with automatic shutdown, and a 3-year residential warranty. One contradiction sits inside the listing: the bullets say the unit weighs just over 47 pounds, while the spec table says 51.0 pounds, so this article follows the bullets. The listing also notes the unit is not available in California.
Who it's for: campers and homeowners who want low stated noise, app monitoring and carbon monoxide shutdown in a 2200-watt unit. Who should skip it: shoppers who need a 240V outlet or a California-legal unit, since the listing states neither.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For an inverter generator, safety means stated CO sensors, overload and low-oil protection, GFCI outlets and fuel shutoff; a pick that states none scores zero on that line. Three of the five picks state a warranty term and two state none. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Westinghouse ecoGen10000 | 9.7 | 32 | 21 | 21 | 8 | 4 |
| ComJoy 2400 Watt Inverter | 9.6 | 28 | 20 | 20 | 8 | 2 |
| WEN 2500 Watt Inverter | 9.5 | 28 | 22 | 21 | 3 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best inverter generator
Match running watts to the load, not just peak watts
Peak watts start a motor; running watts keep it going, so size the load on running watts. The Westinghouse lists 7600 running watts and 10000 peak watts, the ComJoy lists 2200 rated watts and 2400 peak watts, and the WEN lists 1900 rated watts and 2500 surge watts. For sensitive electronics, note the clean-power claims: the Westinghouse and ComJoy state less than 3% THD, while the WEN states clean power without a THD figure. Our quiet lightweight inverter generator picks cover smaller units in the same class.
Weigh weight against output
The Westinghouse lists 147.7 pounds against 7600 running watts, while the WEN lists 37.5 pounds against 1900 rated watts and the ComJoy lists 41.8 pounds against 2200 rated watts. A heavy open frame unit suits a fixed spot at home; a light unit suits camping and moving between sites. Two picks state no weight, so confirm it before ordering if you plan to carry the unit.
Check start, outlets and run time
Starting differs across the picks: the Westinghouse lists remote electric start with an included key fob, push button and recoil start, while the WEN and ComJoy state no remote start. Outlets differ too: the Westinghouse lists four GFCI 120V outlets plus transfer-switch-ready 120V and 120/240V outlets, and the WEN lists two 120V receptacles and two 5V USB ports; the ComJoy states no outlet list. Run time differs as well: the Westinghouse lists up to 12 hours on a 5.28 gallon tank, and the ComJoy lists up to 5 hours at 50% load or 10 hours at 25% load on a 0.92-gallon tank. A licensed electrician should install any transfer-switch connection. See our inverter generator set guides for the wider power station range.
Read the warranty lines closely
Coverage splits the picks: the Westinghouse states a 3-year limited service, labor and parts term, the WEN states a three-year limited term, and the ComJoy states 1 Year. Two picks state no warranty term, so their coverage is unknown until the listing says more. A longer stated term matters more on a unit that will run through many outages.
Sizing Notes
- Match running watts, not peak watts, to the loads you plan to run together.
- Match the stated outlets and voltage to the devices you plan to plug in.
- Match stated run time and tank size to how long the outage or trip is expected to last.
- Compare stated noise figures at the same load and distance before choosing a campsite unit.
- Check weight, outlets and warranty on any pick whose listing states few details before ordering.
FAQ: power away from the grid
What is the difference between running watts and peak watts?
Running watts are the steady output and peak watts are the short starting output. The Westinghouse lists 7600 running watts and 10000 peak watts, the ComJoy lists 2200 rated watts and 2400 peak watts, and the WEN lists 1900 rated watts and 2500 surge watts. Size the load on the running or rated figure.
Which pick here lists the longest run time?
The Westinghouse lists up to 12 hours of run time on a 5.28 gallon fuel tank. The ComJoy lists up to 5 hours at 50% load or 10 hours at 25% load on a 0.92-gallon tank. The WEN and two other picks state no run time.
Which pick weighs the least?
The WEN lists 37.5 pounds, lighter than the ComJoy at 41.8 pounds and the Westinghouse at 147.7 pounds. Two other picks state no weight.
What warranty terms do these picks state?
The Westinghouse states a 3-year limited service, labor and parts term, the WEN states a three-year limited term, and the ComJoy states 1 Year. Two other picks state no warranty term.
Can a second unit double the output?
The ComJoy supports parallel operation to double output, with the parallel kit sold separately. The other full-data picks state no parallel capability.
