Description

Zoom on the DuroMax XP4500iH

In a nutshell, the DuroMax XP4500iH is a portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The DuroMax XP4500iH in use

The DuroMax XP4500iH

The dual-fuel technology of the DuroMax XP4500iH allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3600W and a starting wattage of 4500W. If propane-powered, it gives 3420 rated watts and 4275 starting watts. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

With a noise rating of 65 dBA (just slightly more noisy than background music), the inverter generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the XP4500iH can also be remotely started (key fob included).

Regarding its running time, the XP4500iH, with a 2.64 gallons fuel capacity can operate for around 8 hours at 50% load with a full tank of gasoline (fuel consumption around 0.33 GPH). When using propane, it can run for around 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).

As the XP4500iH produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
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) allowing you to conveniently charge electronics such as mobile phones and tablets.

This DuroMax generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The DuroMax XP4500iH is an inverter generator and has an encased design of the following dimensions: L24 x W19 x H22 in. Thus, it is more aesthetical than conventional, open frame products. The featured design follows the latest trends and is ideal for easy and recreational use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 115 pounds. However, its challenging mobility is solved by its set of 2 wheels and its telecospic handle, which will ease its displacement, once it is on the floor.

Features

Panel of the DuroMax XP4500iH

The XP4500iH's control panel

One of the many XP4500iH's features is the data center, included in its control panel, which conveniently provides information on the voltage, fuel level, lifetime run hours, frequency and power output and thus, helps you monitor its activity and status.

In addition to this info, when its oil levels are insufficient, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.

The fuel level of the inverter generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

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

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP4500iH also comes with some accessories: key fob, funnel, tool kit, propane hose and battery charger are included.

Emissions

The DuroMax XP4500iH is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

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 generators of similar power (between 3500 and 4500 W).

  • At a weight of 115 pounds, the DuroMax XP4500iH places in the expected weight range of the generators in the 3500-4500 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 65 dBA. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Regarding its autonomy, the autonomy of the XP4500iH, reaching around 8 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.33 GPH (gallon per hour) at 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the DuroMax XP4500iH is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
