Power & Run Time

The DuroMax XP4500iH in use

The DuroMax XP4500iH

Featuring dual-fuel technology, the DuroMax XP4500iH provides 120V, as well as versatility and power. Running on gasoline, it delivers a running wattage of 3,600W and a peak wattage of 4,500W. Alternatively, when fueled by propane, it offers 3,420 running watts and 4,275 peak watts. In addition, as it is parallel capable (XP4500iH-PK parallel kit (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.

DuroMax’s Switch On Demand technology allows you to switch from propane to gasoline or from gasoline to propane while the generator is running.

The inverter generator features a manual recoil starter system and also a hassle-free and practical electric starter (battery included). It is rated for a noise of 65 dBA (just slightly more noisy than an office). To add further convenience, the XP4500iH can be remotely started (key fob included).

Regarding its running time, the XP4500iH, with a 2.64 gallons fuel tank, can operate for up to 16 hours with a full gasoline tank (with fuel consumption estimated at around 0.17 gallons per hour). It also offers up to 19 hours (on a 20 lbs tank - propane consumption around 0.25 GPH) of operation when using propane.

The XP4500iH generates a clean sine wave with <3% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.

Outlets

The control panel features 3 AC outlets as follows:

Duplex 120V 20A (5-20R) GFCI
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (1 x USB-A and 1 x USB-C) enabling convenient charging of devices like mobile phones and tablets.

Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this DuroMax generator is RV Ready, ensuring compatibility with recreational vehicles.

Portability

With its enclosed inverter generator design (L24 x W19 x H22 in), the DuroMax XP4500iH offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The featured design follows the latest trends and is ideal for easy and recreational use.

Despite its 115 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. Nonetheless, the limited maneuverability is compensated for by utilizing its set of 2 wheels (⌀4.5") and its telecospic handle, which facilitates shifting once the generator is set on the ground.

Features

Panel of the DuroMax XP4500iH

The XP4500iH's control panel

Embedded in the control panel of the XP4500iH, a digital data center serves as a vital feature, offering comprehensive information on the lifetime run hours, frequency, fuel level, power output and voltage to aid in monitoring activity and status.

In addition to this info, the device's light indicators will illuminate to indicate if the generator is ready, its oil levels are insufficient and the generator is overloaded.

Equipped with a built-in fuel gauge, the inverter generator facilitates swift gas level checks.

Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during operation.

The XP4500iH 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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroMax XP4500iH, the following accessories are also included: key fob, tool kit, propane hose, battery charger and funnel.

Product Videos

The DuroMax XP4500iH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4500iH compare to inverter generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 115 lbs, the DuroMax XP4500iH belongs in the expected weight range for inverters which can produce between 3500 and 4500 rated watts. If weight is an important consideration for you, the Genmax GM4600iAEFIC stands out as one of the top contenders in this power category, with a dry weight of 58.4 pounds.
  • When comparing it to devices with a similar running wattage, this inverter generator's lowest noise level of 65 dBA puts it alongside the noisier units. If you'd like a less noisy alternative, the Westinghouse iGen5000DF is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
  • At a 25% load, the XP4500iH's up to 16 hours of runtime on a full tank fall within the average autonomy range for similarly powerful inverter generators. If runtime is a priority for you, the Firman W03661OF stands out as one of the generators with the longest run time in its power range, providing up to 25 hours of continuous use.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator has a better fuel efficiency than other units in the aforementioned output range, consuming approximately 0.17 GPH (gallon per hour) at 25% load. If you're placing a high priority on fuel consumption, the Champion 201319, with a low fuel consumption rate of 0.16 GPH, could be an option to consider.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the DuroMax XP4500iH 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.

    I recently install a 20kw Kohler genset at my home on the Washington coast. While that unit will fulfill all our needs it’s very thirsty, very thirsty.
    So I purchased the xp4500ih to power our entertainment system, internet, fridge and a couple led lights for extended periods. This way the Kohler can stand by to handle the big stuff like cooking, laundry & bath time.
    What attracted me to the Duromax the design. I really like the display for the information center. It’s a nice bright vivid display and it shows voltage hertz’s wattage & hours. It also integrates a fuel gauge so you’re not having to remove the gas cap and shine a flashlight to see your gas level.
    Also, I like the independent controls.
    Ignition, gas valve, fuel selector and start/stop switch. To me the ability to shut off the fuel flow and run the carburetor dry is an important feature especially when running 10% alcohol fuel.
    Another feature I appreciate is the battery maintainer jack on the front panel and included 12v trickle charger.
    When the powers back on this unit is quick & easy to put away properly, shut off the gas and let the carb run dry then plug in the battery tender, that’s about it.
    For camping or RVing the remote fob start would be invaluable especially when it’s cold dark & stormy. I have tested the remote start feature but haven’t had and need to use it in practice yet.
    The primary reason I chose a unit that runs on propane is the storage issue. Gasoline goes bad, 10% ethanol gas goes bad even faster but I can keep a couple 30lb LP tanks at the ready almost indefinitely not to mention longer run times.
    The overall design and attention to detail is quite good but there is a couple areas where improvement could be made.
    First is the weight, fueled up it’s a two person lift. Unless you’re big young and strong you’ll probably strain your gizzard trying to lift this into a pickup. Get a ramp and a helper.
    Second is oil changes. Many generators now include a oil drain tube with a valve or cap that makes maintenance time a no mess operation. Unfortunately this model forces you to elevate the unit and drain thru an opening in the bottom.
    This is a issue I’m dealing with soon by retrofitting my own system.
    The next comment is more of a convenience issue. I’d like to have a quick connect for the propane hose, several other manufacturers have included this in their design and not having to mess around with a wrench on a dark rainy night would be a big plus.
    Price could be another point of contention for some but really for the features this unit offers I really think it’s still a good value.
    At this moment the only question I have is durability and only time will tell but I went above and beyond with the break in process & am diligent with maintenance so hopefully I’ll get years of service.
    One last thing. I can’t for the life of me find a parts list and diagram for this product or any Duromax product. I do my own maintenance and it unsettles me just a bit that there’s no service or parts manuals readily available.

    + PROS:
    • 2x20Amp GFI outlets
    • 30Amp RV plug
    • Remote start
    • Wattage & Fuel on display
    • Separate controls(fuel)(ignition)(start)
    • Battery maintainer
    • Switch on fly fuel selector
    • No tool access panel
    • Very quiet
    • Overall, feature rich
    - CONS:
    • Heavier than most in class
    • Clumsy oil drain process
    • Modest gasoline capacity
    • Threaded LP connection
    • Parts/Service diagram not readily available.
    • Not for novice user.
