Find out how Firman and Predator generators typically compare so you invest in the right model for your situation.
The main differences between Firman and Predator generators are that Predator generators tend to be slightly more reliable and budget-friendlier.
On the flip side, Firman generators tend to come with more extensive features and longer warranties.
If you want certain specs like dual fuel, tri fuel, or a remote start, one of the Firman generators will likely suit your needs better.
On the other hand, Predator generators tend to be better in the gasoline-only category if you can find the right model for your needs.
That being said, it is worth noting that if you don’t necessarily want to stick to Firman or Predator models, certain other brands tend to score better on our lists of the best generators.

Firman vs Predator generators in-depth
The comparison table above gives a helpful overview but you may want more in-depth information about the differences between Firman and Predator generators in these areas.
Reliability reputation
Before investing in a portable generator from Firman or Predator, you want to know how long they will last and what the risk of technical problems is.
When it comes to Firman generators, the individual models can vary a lot.
There are some Firman generators that are seemingly very reliable due to the overall positivity of the customer reviews.
That being said, seemingly more often, the reliability of this brand is somewhat average.
On the other hand, the customer reviews of Predator generators are almost always very positive.
At the same time, you do want to know that these generators do not have the best reputation in terms of reliability.
In turn, the people who invest in a Predator generator may give positive customer reviews more easily.
So you can say Predator generators generally have the upper hand over Firman generators in this area but the durability may not be perfect.
Winner: Predator generators (but they do not have the best durability reputation either)
Extra Features & Specs
There are a few features and specs like electric start, remote start, dual fuel, CO sensors, etc. that are not included in all portable generators.
These may not be essential but they can improve your experience of your Firman or Predator generator.
Individual models can vary but Firman generators tend to do relatively well in this area.
You should have no problems finding models with electric starts, dual fuel, and CO sensors.
Even remote starts tend to be relatively common compared to other generator brands.
On the other side, Predator generators do often come with electric start and CO sensors but these are typically the “only” things you can expect.
Harbor Freight did just release the Predator 5000 which is a dual fuel inverter generator.
However, for now, this is the exception.
Winner: Firman generators
Noise levels
How much noise Firman and Predator generators make is often an important detail.
Especially on an RV camping, at an event, or in a small neighborhood.
That being said, if you compare models from the same power level and type (inverter vs non-inverter), Firman and Predator generators tend to have similar noise levels.
More specifically, both of these brands are somewhat average in terms of decibel ratings.
There are typically both quieter and louder generators available.
Winner: Generally similar
Warranties
Even if you choose a portable generator with impressive reviews, there is still a tiny chance of encountering technical issues.
For this reason, the warranties of Firman and Predator generators deserve a mention in this comparison.
Firman generators tend to come with three years limited warranty.
I have not found any details around this but that likely means the commercial warranty will be shorter than that.
On the other hand, Predator generators are relatively bad in this area with limited warranties of 2 years for the emissions control system and 90 days for the product.
So while you hopefully won’t need it, Firman generators do better than Predator generators in terms of warranties.
Winner: Firman generators
Price
Having the right generator for your preferences and needs is important but the prices of Firman and Predator likely matter too.
Firman generators tend to be slightly above average in price compared to similar alternatives.
On the other side, Predator generators tend to be about average to slightly below average in terms of the investment required.
In short, Predator generators tend to be more budget-friendly than Firman generators. At least in the short term.
Winner: Predator generators
Example: Firman WH03242 vs Predator 3500
When it comes to specific models, the Firman WH03242 vs Predator 3500 comparison is popular for these two brands.
Some of the main differences are that the Firman WH03242 has a dual fuel feature and slightly more power potential than the Predator 3500.
On the other hand, the Predator 3500 is more budget-friendly, is more reliable, and runs longer on a full tank of gasoline than the Firman WH03242.
In terms of noise levels, these portable generators are very similar.
So if you really need the extra watts and/or want to be able to run on propane, you could consider the Firman WH03242.
If not, the Predator 3500 will generally be a better choice.
Winner: Generally Predator 3500
Winner: Firman WH03242 if you want dual fuel feature and/or a few extra watts
Are Firman or Predator generators right for you?
In short, Predator generators tend to be slightly more reliable (but not necessarily more durable) and budget-friendlier.
On the other hand, Firman generators tend to be more extensive in terms of features and come with longer warranties.
If you plan to use your generator a lot and/or want specific features like dual fuel, tri fuel, and remote start, certain Firman models could be a good idea.
That being said, if you are alright with a more basic model, Predator generators will often be better.
It is worth mentioning that there are a decent number of alternatives to these options that score higher on our list of good generator brands.
In simpler words, you will often be in a situation where both Firman and Predator generators are not the number one best choices.
