Description
Zoom on the DuroMax XP28000iHT
To sum up, the DuroMax XP28000iHT is a powerful portable inverter generator tailored for:
- Professionals in need of safely powering high-intensity work or lighting equipment
- Small homeowners in search of a full power backup solution
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The DuroMax XP28000iHT delivers 120/240V and is equipped with a tri-fuel technology, enabling it to operate on gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 22,000W and a peak wattage of 28,000W. Switching to propane provides 20,000 rated watts and 25,000 peak watts, while natural gas operation delivers 16,000W of rated wattage and 20,000W of starting wattage. The impressive running wattage makes this unit one of the biggest inverter generators currently on the market.
With a noise rating of 70 dBA (just as noisy as a shower), the inverter generator features an intuitive and practical electric starter (battery included). Moreover, to offer you even more convenience, the XP28000iHT can also be remotely started (key fob included).
The generator also supports 2-wire start, enabling integration with compatible automatic transfer switches (ATS), solar battery systems, or hybrid inverter setups via a low-voltage contact-closure control circuit.
The running time of the XP28000iHT, with its 12.7 gallons fuel capacity, can reach around 9 hours at 50% load on a full tank of gasoline (fuel consumption around 1.41 GPH). With propane, it can reach around 3.3 hours (on a 20 lbs tank - propane consumption around 1.42 GPH).
Thanks to its low <5% Total Harmonic Distortion (THD), the XP28000iHT produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.
Outlets
The control panel features 7 AC outlets as follows:
Moreover, it presents 1 DC outlet: there's a 48-58V 10A output to charge your home backup Li-ion batteries.
The XP28000iHT's twist-lock L14-30R receptacle makes it transfer switch ready, enabling hassle-free connection to your breaker box for powering your home during outages.
Portability
Since the DuroMax XP28000iHT is an inverter generator, its closed design (L39.3 x W31 x H34.5 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.
Despite its weight of 466 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. Still, once it is on the ground, its set of 4 wheels and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
Features
Featuring a digital data center on its control panel, the XP28000iHT offers you convenient access to essential information about the voltage, lifetime run hours, frequency and power output, facilitating effective monitoring of its activity and status.
In addition to this info, the device’s light indicators will display if the generator is overloaded, the oil level is too low and the generator is ready.
The inclusion of a built-in fuel gauge in the inverter generator streamlines gas level checks for quick and convenient assessments.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
The XP28000iHT also benefits from DuroMax’s CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the DuroMax XP28000iHT is bundled with additional accessories: tool kit, battery charging cables, key fob, natural gas hose with NPT adapter, funnel, propane hose and battery charger.

The DuroMax XP28000iHT versus other generators
The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP28000iHT compare to generators of similar power (between 14000 and 22000 W).
- With a weight of 466 lbs, the DuroMax XP28000iHT is notably on the heavier side among generators in the 14000-22000 rated wattage range. If weight is your top priority, one of the champions in this power category is the Pulsar PGD170TiSRCO, weighing just 313 pounds.
- With a lowest possible noise of 70 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Pulsar PGD170TiSRCO, whose lowest noise levels reach just 66 dBA.
- Regarding its autonomy, the XP28000iHT can run for around 9 hours at a 50% load, aligning it with the lower performers in its power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen14500DFc, reaching around 11 hours.
- While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. As this inverter generator uses an estimated 1.41 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. To prioritize fuel savings, we advise considering the Westinghouse WGen14500DFc, which stands out for its gasoline efficiency, consuming just 0.95 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 14000-22000W generators, the DuroMax XP28000iHT is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
