Things to Consider

Having looked at our favorite Powerhorse generators, let’s go through a brief history about the brand and things that will help you pick the right model for your home or business.

Powerhorse generators: What you should know about them?

Powerhorse generators are marketed and sold by Northern Tool + Equipment. The family owned business was founded by its current Chief Executive Donald Kotula back in 1981.

It started out as a mail-order firm and has since grown into the ultimate one-stop shop for hardworking DIYers and professionals. Although the company is based out in Faribault, Minnesota, the actual Powerhorse generators are manufactured in China.

The company also claims to sell useful machines and power tools at great prices as well as back them with excellent customer care. Apart from generators, they offer pressure washers, air compressors, welders, and power tools, and some of these can be powered by the same Powerhorse generators when working far away from electrical outlets.

5 Outstanding Powerhorse Generators – Reviews and Buying GuideGenerator type: inverter or conventional?

Probably the main thing to figure before buying a generator is whether you want an inverter or traditional generator. Find below the differences illustrating the pros and cons of each in different aspects.

Current: conventional generators only produce AC current while inverter produces energy in 3 phases – high frequency AC then DC and back to a steady AC current. As a result, inverter generators have the benefit of minimal harmonic distortion, making them clean and safe to use with sensitive devices and appliances.

Power and fuel efficiency: inverter generators are less powerful than conventional counterparts. Most inverters range anywhere from 1,200 to 4,000 watts, whereas conventional models can reach over 10,000 watts. However, as we have seen, you can still find a few inverters with a lot of power such as the Powerhorse 11,000-watt Portable Generator. Inverters are also more fuel efficient than conventional models because of how they produce the final AC current.

Parallel connection: inverter generators allow for parallel connections to make up for the lower power output. Conventional models, however, lack this kind of flexibility.

5 Outstanding Powerhorse Generators – Reviews and Buying GuideNoise: inverters are very quiet in the region of 50–58 dB of noise, whereas conventional generators tend to average 65 dB.

Size and portability: conventional generators are bulky and heavy because of their power, which is associated with large engines and large fuel tanks. Though most of them have wheels for easier movement, they still cannot be as portable as inverter generators. Some inverters can be even carried on their handles, with the Powerhorse 2,000-watt Portable Inverter Generator being a perfect example.

How much power do you need?

This depends on your usage needs. For instance, if you need to power well water, you own gas or electric heaters, and run most of your household appliances, generators in the range of 3,500 watts to 5,000 watts should be sufficient.

For RV, camping, tailgating and boating, a 2,500-watt generator is ideal, though you may need to check the power requirement for the electrical equipment you have on-board, including blenders and coffee pots.

How long you need to run your generator?

Obviously, this depends on the tank capacity, load requirements, among other factors. Some generators are designed to provide power for 8 hours, others 10 and some up to 16 hours. For instance, the Powerhorse 7,500-watt Inverter Generator can run continuously for 16 hours on 1/4 load, while the Powerhorse 11,000-watt Portable Generator operates for 8.5 hours on a ½ load, yet both machines have 6.6-gallon tanks.

How often you use it will also determine how long it can run on one full tank. A portable gasoline generator, mainly used on the go purposes such as camping, is expected to last a while. If you are using a backup generator when there’s a power outage, it can conserve fuel to use another day because blackouts rarely last that long.

Safety features

A must-have for every generator is overload protection, which protects against potentially dangerous effects of an overload current or a short-circuit current. Improper application of an appliance or equipment’s voltage rating can result to damage, personal injury or even cause death to humans handling the equipment.

Something common with Powerhorse generators is the 100% copper-wound heads that prevent overheating when the machines are running at maximum power.

Another important safety feature is the low oil shut-off, again present in nearly all Powerhorse generators. In the event that oil falls below minimum, the machine shuts down to prevent engine damage.

Tip and tricks

Below are some basic measures that you can take to ensure safe operation of your generator.

  • Make sure the installation location is dry, stable and level. This must be outdoors and far from air intakes. The machine needs enough, unobstructed flow of air so that proper cooling of the engine and generator head is possible. Ensure that the generator is in area that’s not exposed to direct sunlight, rain or snow.
  • Ensure that the machine is properly grounded to prevent electrical shock. You should consult a qualified electrician to determine grounding requirements and follow procedures that conform to local regulations.
  • The battery for the electric starter should be fully charged before inserting into the unit.
  • Carefully connect the unit to the electrical system using the automatic transfer switch. If there’s no transfer switch, plug the essential devices directly into the unit.

5 Outstanding Powerhorse Generators – Reviews and Buying GuideWhen it comes to maintenance, observe the following:

  • Check receptacles before every use to ensure that they are not broken or cracked.
  • Monitor the fuel system and check for leaks on a frequent basis.
  • Clean dust and debris from the generator as soon as it accumulates, using a damp cloth or soft bristle brush, but never with a pressure washer or garden hose.
  • Avoid storing the generator with the battery charger connected as the battery can overcharge and boil dry.
  • Always make use of the handle and wheel kit to move or lift the generator and call for a second hand before generators tend to be heavy.


Most Powerhorse models have a 2-year limited warranty along with a 90-day commercial warranty. The former applies to household use whereby the manufacturer can replace defective parts or repair them at no charge, except if the equipment fails because of lack of proper maintenance. Any abuse, misuse, improper installation and alteration will void warranty. The same conditions apply to commercial uses, such as when the generator is bought for a business or to be used for income generating activities.

Simply check if the generator has an outlet that’s compatible with the plug of the power cord coming from your recreational vehicle. If there’s none, you will need to purchase an adapter that is suitable for both your generator and RV plug. For example, a 2,000W unit will require a 120V, 15-amp adapter that is compatible with the 30 or 50-amp power cord from your RV. Just so you know, a 30-amp power cord has 3 prongs while a 50-amp one contains four prongs.

As far as having reliable, compact and fuel efficient generators go, you can never go wrong with Powerhorse models. Moreover, they are available in a variety of power range, size and some with multiple outlets to power nearly every appliance and device in your home.

Our top pick in this respect is the Powerhorse 7,500-watt Inverter Generator. Its 420cc engine starts quick and easy each time and it runs super-quiet at 55 dB. We liked its variable throttle for conserving fuel, intuitive control panel, 16-hour runtime and multiple receptacles.

Coming in second is the Powerhorse 2,000-watt Portable Inverter Generator. This 46-pound portable model is great for any activity on the go, providing clean, safe energy for sensitive devices. Engine Smart Controls make it super fuel efficient.

Finally, the Powerhorse 3,500-watt Inverter Generator is the most ideal for the average household. With 11 hours of runtime, 57 dB noise level, electric and recoil start options, and the option to add an extra 2,000W or 3,500W Powerhorse model, this model has the right balance of application and price.

So, have you found your best powerhouse generator from this post? Over to you.
