Description

Zoom on the DuroMax XP13500iHT

In short, the DuroMax XP13500iHT is a powerful portable inverter generator adequately designed for:

  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The DuroMax XP13500iHT in use

The DuroMax XP13500iHT

The DuroMax XP13500iHT 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 10,500W and a peak wattage of 13,500W. Switching to propane provides 10,000 rated watts and 12,750 peak watts, while natural gas operation delivers 9,000W of rated wattage and 11,500W of starting wattage. In addition, as it is parallel capable (parallel kit not included), this power can be increased when linked to another similar or compatible unit.

The inverter generator, rated for a noise of 66 dBA (less noisy than a normal conversation), provides flexibility in starting, offering both a conventional pull-start mechanism and an intuitive and practical electric starter (battery included). Furthermore, for added convenience, the XP13500iHT offers remote starting capabilities (key fob included).

Regarding its running time, the XP13500iHT, with a 8 gallons fuel capacity, can operate for around 10.8 hours at 50% load with a full tank of gasoline (fuel consumption around 0.74 GPH). When using propane, it can run for around 4.6 hours (on a 20 lbs tank - propane consumption around 1.02 GPH).

Featuring a <3% Total Harmonic Distortion (THD), the XP13500iHT delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.

Outlets

The control panel features 4 AC outlets as follows:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Moreover, it boasts 1 DC outlet: there's a 48-58V 10A output to charge your home backup Li-ion batteries.

Since it boasts a twist-lock L14-30R receptacle, the XP13500iHT is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.

Portability

As the DuroMax XP13500iHT is an inverter generator, its encased design (L32.3 x W23.6 x H27.4 in) offers more aesthetics than a conventional, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

Despite its 233.4 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder easy portability. Despite the restricted maneuverability, its set of 4 wheels (⌀6.7") and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.

Features

Panel of the DuroMax XP13500iHT

The XP13500iHT's control panel

For easy status and activity monitoring of the XP13500iHT, its control panel integrates a digital data center, offering insights into the voltage, remaining run time, power output and frequency.

In addition to this info, the device's light indicators will illuminate to indicate if the generator is ready, the generator is overloaded and the oil level is too low.

Featuring a built-in fuel gauge, the inverter generator offers quick, convenient, and easy gas level checks at a glance.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

The XP13500iHT 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.

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the DuroMax XP13500iHT also includes several accessories: battery charger, key fob, propane hose, tool kit, natural gas hose with NPT adapter, funnel and battery charging cables. An official running cover is also available, as a separate purchase.

The DuroMax XP13500iHT versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP13500iHT compare to multi-fuel generators of similar power (between 10000 and 11000 W).

  • Tipping the scales at 233.4 lbs, the DuroMax XP13500iHT qualifies as one of the heavier options among multi-fuel generators rated between 10000 and 11000 watts. In terms of weight, one of the champions in their power range is the Genmax GM12000XiT, standing at just 194 lbs.
  • With a noise rating as low as 66 dBA, this inverter generator is among the quieter options available in its type and power range. If you are concerned with noise, check out the Genmax GM12500iET, which is one of the least noisy generators in its power range, with a noise rating of just 62 dBA.
  • Since the XP13500iHT boasts with a run time of around 10.8 hours at 50% load, it can be safely judged as a device of a higher run time than most multi-fuel generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroStar DS14000iX, as it provides around 12.5 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Among devices of similar power, this inverter generator has one of the best fuel efficiency, with consumption rates of around 0.74 GPH (gallon per hour) at 50% load.

Price comparison

As you can see from these interactive charts, when compared to other 10000-11000W multi-fuel generators, the DuroMax XP13500iHT 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.
