Where Are Predator Generators Made?


Since this brand of generators is sold by Harbor Freight, you should not be surprised to find out that these inexpensive generators are made in China. The company’s name is Power TEAM which is a subsidiary of Maystar International Group.

The Maystar company was started in 1973 and doe sits manufacturing in Guangzhou, China. This does not mean that the Predator is a bad generator but its quality may not be on the same level as Honda, Yamaha, or other top generator brands.

While being made similar to both Honda and Yamaha generators, this brand is not a clone of those two top brands.

Predator 3500 Generator Life Expectancy


There are differing opinions on this topic. Some people will say that with proper maintenance, you can have the Predator generator last up to 20 years. Other people claim that under the same conditions, it will last for 50 years.

Generally, longevity for generators is given in hours not years. Some people will say 10 to 15,000 hours is a good run under proper maintenance while others may say 20,000 hours.

It will depend on a variety of factors that will determine how long your model will last. If you use your generator sparingly, then it may reach that 50-year mark. It is hard to predict as some RV situations can have electrical problems that ruin the generator faster than it should have died.

If you leave it exposed to rain, mist, snow, and other moisture-generating weather conditions, do not expect it to last for a very long time. Just make sure to take care of it properly under all weather conditions so the device can last a very long time.

How Many Hours Will a Predator 3500 Generator Last?

Again, this will depend on how well you care for your generator. As we said in the previous section, you can count on using it for roughly 10,000 to 15,000 hours. Some people may get more and others may get fewer hours of use out of this generator brand.

The manual may call for oil changes every 6 months or 100 hours but that is not set in stone either. You do not have to do it on the dot of 6 months or 100 hours. You will have some leeway there.

But maintaining the generator does include proper and regular oil changes. Also, you need to use the right fuel as the manual does clearly state that 87+ octane unleaded gas is the only fuel you should use in the engine.

It also states that you cannot go above E10 as too much ethanol will ruin the engine. If you live in a region of the country that uses higher percentages of ethanol in its gas supply, you may have a hard time abiding by those instructions.

Also, make sure to use the right oil as that will help protect your generator from harm.

How Quiet Is The Predator 3500?


This generator is rated at 57 decibels. That makes it quieter than many top brands and more expensive generators. That is one reason this brand is so popular. It can be used in tight camping situations without really disturbing your neighbors.

To give you an idea of how loud 57 decibels is, here is where it lies on the comparative noise chart. 57 decibels is just below normal and conversational background music. Then it is about 17 points above normal house noise.

Then it is 18 points below a vacuum cleaner or average radio volume. The rating you want to avoid is 85 decibels as that is where the problem for your hearing starts. Anything louder than 85 decibels is harmful to your hearing.

80 to 89 decibels is an air conditioner and power lawn mower rating. This is also the noise rating for heavy traffic and a busy restaurant. Believe it or not, a toilet flushing can reach 75 decibels.

The average daily noise level ranges between 46 and 70 so the Predator is well within average and safe noise levels.

Our Predator 3500-Watt Inverter Generator Review

The quiet noise level does help view this generator brand and generator in a positive light. You do not want to make a lot of noise when you are camping near other RV or trailer owners. This generator will achieve that level of neighborly behavior.

This generator may not be the best unit on the market but its lower price will fit most budgets and you can get some good use out of it over the years. It is a good generator for how and where it was constructed.

Plus, this model puts out some very good starting and running watts which is what you need when you are boondocking. The drawback to this specific unit will be that it does not have a remote start. And it does not have a very large gas tank.

That latter drawback means you may be refilling this generator a lot more than you want to. 11 hours on 1/4 load is impressive but if you need more than that, then you need a nice gas supply on hand to keep it running.

While the price is attractive, the quality and run-time are just not there. It is a good backup generator to have but not the best for primary use.

How Long Can a Predator 3500 Run on Full Load?


Unfortunately, not many people talk about this important factor. It is not impressive to talk about and may scare some potential customers away. What we can tell you is that the Predator will run for 11 hours at 25% load.

However, if you increase the load to 50% then your run time drops by more than half. You can expect to use the generator for about 5 hours at 50% load. What do those two rates tell you?

You may get about 2 hours of use on a full load. The more power you need, the harder the generator works. The harder the generator works, the more gas it uses up.

What this also tells you is that you need a very good gas supply on hand or at least a gas station very close by to run this generator at full load all the time.

Some Aditional Words

For most RV and trailer owners, you do not need an expensive generator. Most RV owners are not full-timers nor do they boondock a lot. A Harbor Freight Predator 3500 inverter generator may just be what you need for your RV living situation.

They are inexpensive, do a good job, and can last for decades if you take care of them. They are good for your budget as well.
