What it is
The DuroMax XP2300iH is a small inverter generator that runs on gasoline or propane, built around an 80cc engine with all-copper windings. On gasoline, it delivers 1,800 running watts and 2,300 starting watts, with a 1.1-gallon tank good for roughly 13 hours at a quarter load. On propane, output drops slightly to 1,700 running watts and 2,150 starting watts, but runtime nearly triples to about 38 hours at a quarter load on a standard 20-pound tank, since propane burns more efficiently at this scale than gasoline does.
The control panel includes two 120V household outlets, one 120V 30A L5-30R outlet, one USB-A port, and one USB-C port, plus an LCD display showing hours run, voltage output, and load level. Starting options include a recoil pull and remote start with an included fob. At 53 pounds with an integrated carry handle, it is light enough for one person to lift into a truck bed or RV storage compartment without a wheel kit.
Why it works
This is DuroMax's current entry-level inverter, replacing the older single-fuel XP2200iS, and the upgrade is meaningful:
CO Alert, where the model it replaced had none
DuroMax's older XP2200iS, a gasoline-only inverter close to this one in size and price, does not include a carbon monoxide sensor. The XP2300iH does. That is a real safety upgrade in the same product tier, not just a wattage bump.
Genuinely clean power
Total harmonic distortion stays under 3%, comfortably inside the range considered safe for laptops, phones, and medical devices. This is real inverter-quality power, not a conventional generator marketed with a low-THD claim.
Dual fuel with the parallel cable included
Gasoline or propane gives you a choice depending on what is on hand, and propane's long shelf life makes it the better fuel for a generator that sits unused for months at a time. The cable to link two units for double the output ships in the box, rather than as a separate purchase.
The one thing to know
Carbon monoxide safety is non-negotiable
Portable generators produce carbon monoxide, an odorless gas that can reach lethal concentrations indoors within minutes. The CPSC recommends placing any portable generator at least 20 feet from all doors, windows, and vents, with the exhaust pointed away from the home. Never run a generator indoors, in a garage, on a covered porch, in a carport, or in any enclosed or partially enclosed space, even with doors or windows open. DuroMax's CO Alert provides a backup shutoff if carbon monoxide reaches dangerous levels near the unit, but it is not a substitute for correct placement. Install battery-operated CO detectors on every level of your home.

Not CARB compliant
Despite replacing an older model, the XP2300iH is not CARB compliant and is not sold as a 50-state unit under current California emissions rules. California residents will need to look for a CARB-compliant small inverter specifically.
The other thing to know is what this generator is not: a whole-home backup unit. At 1,800 running watts, it will not start a central air conditioner, an electric water heater, or a well pump, and it has no 240V or transfer-switch outlet. Think of it as coverage for a refrigerator, lights, chargers, and a fan, run through extension cords, not a replacement for the breaker panel.
Alternatives worth knowing
WEN DF360iX, for more running watts in a similar class
Meaningfully more running wattage (2,900W versus 1,800W) at a comparable size and price point, with its own CO Watchdog sensor. If you are choosing between these two, the WEN is the stronger pick on raw power. The DuroMax's advantage is a smaller footprint and a slightly quieter rating. Read our review.
DuroMax XP11000iH, for whole-panel home backup
Five times the running wattage with transfer-switch-ready outlets, built for powering selected circuits in a home's breaker panel. Heavier, pricier, and more generator than a camping trip calls for. Read our review.
Honda EU2200i, for the quieter, more established choice
Similar running wattage but gasoline only, with a longer reliability track record and typically quieter operation. If dual fuel does not matter to you, Honda is the safer long-term bet. See our inverter generator comparison.
Maintenance
Run the generator under load for 15 to 30 minutes every 30 days to keep the engine and fuel system in working order. Add fuel stabilizer to the tank for any gasoline storage period longer than 30 days. Propane does not require this step, and its long shelf life makes it the better choice if the generator will sit unused between outages.
Check the oil level before every use; the built-in low-oil shutdown helps prevent damage if it runs low. Follow the manual's schedule for oil changes, typically an earlier first change followed by longer intervals once the engine is broken in. Inspect the air filter and spark plug annually.
DuroMax backs the XP2300iH with a 3-year parts and technical service warranty, supported by a nationwide network of service centers. Register the unit and keep the purchase receipt with your household documents.
NWS recommendation
If you need a light, quiet generator that covers a refrigerator, lights, chargers, and a fan, whether that is for camping, RV trips, or the essentials during a power outage, the XP2300iH does the job with real inverter-quality power and a carbon monoxide sensor its predecessor lacked. Compare it against the WEN DF360iX if running wattage is your priority. Test it on both gasoline and propane before storm season, and place it at least 20 feet from the house with the exhaust pointed away.
