Description

This Powerhorse® Inverter Generator provides super-quiet operation (at just 57dB @ 1/4 load!) and reliable, clean power for safely running tools, appliances and electronics. Great for home, camping, tailgating and outdoor recreation and entertaining.

Zoom on the Powerhorse LC4500i

In summary, the Powerhorse LC4500i is a quiet and compact portable inverter generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 LC4500i's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 4000W and a peak wattage of 4500W. In addition, the device is parallel capable (parallel kit not included) and thus, can be linked to a similar or compatible unit for added power.

With a noise rating of 57 dBA (less noisy than a refrigerator), the inverter generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).

The LC4500i can operate for up to 10 hours with a full tank (fuel consumption around 0.26 GPH), due to its fuel capacity of 2.6 gallons.

The LC4500i produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 3 AC outlets:

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

Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

This Powerhorse generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

Since the Powerhorse LC4500i is an inverter generator, its closed design (L22.8 x W17.3 x H20 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

The LC4500i's dry weight of 99 lbs lets you use its power anywhere needed. Moreover, its set of 4 wheels and its double handle will allow you to effortlessly shift it once it's on the ground.

Features

Panel of the Powerhorse LC4500i

The LC4500i's control panel

The control panel of the LC4500i includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the power output, voltage and lifetime run hours.

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

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Powerhorse LC4500i also is packed along with the following accessories: funnel and tool kit.

Emissions

The Powerhorse LC4500i 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, which makes it suitable for use in forested areas.

The Powerhorse LC4500i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse LC4500i compare to generators of similar power (between 3500 and 4500 W).

  • Regarding its weight, the Powerhorse LC4500i only weighs in at 99 pounds, which means it's one of the lighter generators in the 3500-4500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • As its lowest possible noise is rated at 57 dBA, this inverter generator qualifies as one of the more quiet of the products of similar power. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • As far as autonomy is concerned, providing up to 10 hours of runtime with a full tank at a 25% load, the LC4500i falls into the low end in comparison with other devices of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching up to 22 hours.
  • 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 is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.26 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.14 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Powerhorse LC4500i is on the average side of the price range.

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