Propane generators are popular among campers, contractors, or companies that cannot risk a power outage compromising their activity. These are the main reasons why you would choose a propane powered generator instead of a gas one:

- Propane costs about 50% less than gasoline and has a longer shelf life – in fact, decades can pass without it degrading, given it is stored in a well-maintained tank.
- It’s impossible to waste propane (spill it). If you somehow manage to do so, propane evaporates almost instantly.
- Propane-powered engines are usually quieter.

However, propane is not as efficient as gasoline. If the temperatures drop below 20F, it becomes almost useless. In addition, propane powered generators have a more complicated fuel system – therefore, they are more likely to fail or break and cost more to be repaired. Here are our reviews for the best propane generators for sale in 2016:

Before diving into the best propane generators of 2016, we need to first talk about 2 important notions: Surge rating and running power rating.

A generator’s **surge rating** is the power some appliances need to get started and running. It can be up to four times the amount of power the same appliance needs to run and can be needed for up to 10 seconds. A generator’s **running power** rating is the amount of power it can provide at one time.

Generac propane portable generators are reliable as backups or for short work projects. They are easy to transport and use thanks to a smart design. Although the Generac 6000 and 6001 don’t impress knowledgeable buyers with performance, their design is faultless. They weigh less than most portable generators of similar or larger size and is perfectly balanced.

The **Generac LP 3250**, or **model 6000**, has two regular power outlets of 120V and a rotating 120/240V one that increases its usability and convenience. Its propane tank holder is attached to the outer frame of the generator, which further increases its ease of use. Generac’s suggested retail price for their 6000 model is **$609** – much cheaper than other models.

The LP 3250 has a rated running output of 3250 Watts, but can provide up to 3750 Watts – its maximum starting output. It has a 20 lb tank The Generac 6000 is an average portable propane generator that can be comfortably used during a power outage. With a full tank, it can run for 9 hours at 50% capacity.

The **Generac LP 5500**, also known as **model 6001**, is a propane portable generator which is able to provide a surge power of 6,875 Watts for 10 seconds and a rated alternative current running output of 5500 Watts. It can hold a 30-pound tank or almost 5 gallons of propane. Generac’s suggested retail price for the 6001 model is **$799**.

If the LP5500 has a downside, it would be its short running time. When working at half of its maximum capacity, Generac’s 6001 model can power appliances for a little over 11 hours. While this is an average time, it still cannot compare with top models which can work up to 14 hours at 50% capacity. We’re not thrilled about its efficiency either: The Generac 6001 burns a little over 1 gallon per hour when working at 50% of its maximum capacity.

Nevertheless, Generac generators can be successfully used occasionally, as backup systems.

The GEN series from Sportsman are dual-fuel generators that can use propane or gasoline to provide a reliable amount of power during outages. In addition, they feature a circuit interrupter that shuts the devices off when detecting its current is running through an unintended path, thus increasing the generators’ safety.

However, their downside is hard to ignore: With an 80 dB average noise output, they are loud – extremely loud if we think about other propane powered generators. Therefore, generators in the Sportsman GEN series are not recommended to campers or workers who plan on using it often.

The **Sportsman GEN 4000 LP** has a power surge rating of 4,000 Watts and a running power output of 3,000 Watts. While of average performance, it can successfully power a small home for a few hours.

The **Sportsman GEN 7500 DF**’s surge power rating, on the other hand, is of 7,500 Watts and a running power output of 6,000 Watts. Since it is able to run for about 9 hours on 6.2 gallons of gasoline, its fuel efficiency is below average. However, it makes up for the low efficiency by having a set of convenient features. It has no less than 7 outlets: 4 regular household outlets, one RV outlet of 120 Volts, a 12-volt direct current outlet, and a 120/240 Volts rotating outlet that can support industrial machinery.

The Cummins Onan Residential RS Series is famous for its propane generators for home. Their most noteworthy feature is the patented enclosure, which not only helps with ventilation but drastically reduces the noise output to 62 dB. Therefore, generators in the Cummins Residential RS Series are the quietest in their class. They are next-level generators that can be monitored and controlled remotely, via internet. Their price is close to $10,000.

The **Cummins Onan Residential RS 20A/AC** is a full-use generator that is able to function at temperatures well below the freezing point. The **Cummins Onan Residential RS 14F**, on the other hand, is not equipped for cold weather. Nevertheless, they both can provide energy for a whole house given enough propane. In fact, they are able to power a 15,000 BTU air conditioner in the middle of summer and still have some power available for a handful of smaller appliances.

A Yamaha propane generator from the EF series is generally considered the best propane generator in its price range. However, it is also about 1.5 times more expensive than other portable generators that run on propane.

The **Yamaha EF 4000 DE** has a rated alternative current output of 3500 Watts and a maximum alternative current output of 4000 Watts. It is the “weakest” portable generator in the EF series but still has an above average performance.

The **Yamaha EF 6600 DE/D** has a maximum alternative current output of 6,600 Watts and a rated alternative current output of 6,000 Watts. It is among the most powerful portable generators at the moment. With a maximum noise output of 60 dBA, it can be considered one of the quietest propane powered generators. The suggested retail price for this Yamaha generator is just under $2,500 and comes with a 3-year warranty.

Winco is specialized in tri-fuel portable generators. They are generally more expensive and heavier than average, but they are also among the most powerful portable generators.

The **Winco HPS 6000 HE** has a 5500 Watts rated running power and a 6000 Watts peak power output. It has a 7-gallons tank and can run for 7 hours at full load. If only functioning at half of its full load, the HPS 6000 HE can continuously run for almost 10 hours.

The **Winco HPS 9000 VE** has a 7-gallon fuel tank and can run for 7 hours at half of its full capacity. When working at full capacity, it is able to function for almost 5 hours and a half. It has a peak power output of 9000 Watts and a rated power output of 8000 Watts.

The **Winco HPS 12000 HE** has a 12000 Watts peak power output and a rated power output of 10800 Watts. It is able to run for 9 hours at full load and for almost 15 hours at 50% of its full capacity. It has a 15-gallons tank and produces 78 dB at most.

For generators, Powerland is specialized in tri-fuel appliances. Although a bit noisier than other propane powered generators, they still are considerably quieter than generators using other types of fuels.

The **Powerland 6500** has a peak power of 6500 Watts and a rated power output of 5500 Watts. It features a wheel kit and handle, which makes moving the generator around convenient. As for the price, it starts off at about $800 – cheaper than top models.

The **Powerland 8500** has a 7-gallon fuel tank. Its peak power output is 8500 Watts and a rated power output of 7000 Watts. With a recommended retail price of a little over $1,000, it is considered an average generator that is best to be used as a backup.

The **Powerland 10000** has a recommended retail price of $1,200. Although it might seem a bit costly, it definitely is the best propane generator by Powerland. Its peak power output can reach 10000 Watts, while its rated power output averages 8000 Watts.

All in all, Powerland generators are a viable choice for those who only want a backup generator. However, if you plan on using the generator often, you should probably choose a different brand.

Propane generators are reliable and usually highly efficient. Although a bit more expensive than other types of generators, they quickly pay for themselves. For smaller, portable models, the price difference is not considerable. More powerful models that can be used to power a whole house during a power outage are considerably more expensive, but quality will always be directly proportional to their retail price.
