Zoom on the Powerhorse 4500i
In summary, the Powerhorse 4500i is a compact portable inverter generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating hobbyists looking for a portable power source
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Powerhorse 4500i houses a 224 cc (7.5 hp) OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3,700W along with a peak wattage of 4,500W. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.
Enjoying a noise rating of 64 dBA (just slightly more noisy than background music), this inverter generator gets running thanks to a simple traditional pull-start mechanism.
The 4500i can operate for up to 14 hours with a full tank (fuel consumption around 0.24 GPH), due to its fuel capacity of 3.4 gallons.
As the 4500i produces a clean sine wave, with a <2% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel includes the following 4 AC outlets:
In addition, it provides 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries and two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.
This Powerhorse generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, since the 4500i bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
Portability
The design of the Powerhorse 4500i is a typical, open frame, with the dimensions of L21 x W20.5 x H21.5 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.
With a dry weight of 90.4 lbs, the 4500i can easily follow you wherever your power needs are. In addition, it is even easier to grab and move the generator around thanks to its open frame design.
Features
The device’s light indicators will display if its oil levels are insufficient, the generator is ready and the generator is on overload.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Powerhorse 4500i also is packed along with the following accessories: tool kit and funnel.
Emissions
The Powerhorse 4500i is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Powerhorse 4500i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 4500i compare to inverter generators of similar power (between 3500 and 4500 W).
- As its weight is 90.4 pounds, the Powerhorse 4500i falls in the expected weight range of the inverters in the 3500-4500 rated wattage category. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
- Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 64 dBA can be judged as noisy. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- Regarding its autonomy, the autonomy of the 4500i, reaching up to 14 hours at a 25% load, can be considered as low end, compared to other inverters of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman W03661OF, which is able to run for up to 25 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 not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.24 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.16 GPH, the Champion 200988 is a device you could look out for.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W inverter generators, the Powerhorse 4500i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
