Sportsman GEN4000 Generator Review

Last Updated: 30.09.22

Main advantage


One of the crucial aspects of a high-quality generator is its running time since this can make a significant difference in the user’s experience, by providing more or less reaction time in case of a power outage or emergency.

For this reason, the fact that Sportsman’s GEN4000 model is a recoil start unit that can run for up to 10 hours, all of this with a 50% load on 3.6 gallons of fuel, then you can only imagine why we’ve considered this feature as the one that makes it special among others in its category.


Main disadvantage


Given the 91 pounds it weighs, moving it around is a two-person job, so don’t think that you will be able to accomplish this on your own unless you have a truly impressive physical force. However, if you don’t, you might want to make sure that there’s someone there to help you place it in the spot where it’s needed.

Top 3 features explained



What makes a generator such a useful addition for your home or RV is the fact that you can use it to power many appliances and devices. However, in order to do this, it needs to be compatible with more than one outlet. The good news about this Sportsman generator is that it surely fits the bill.

Equipped with four 120-volt outlets, a 12-volt DC outlet for battery charging, as well as with a 120V RV outlet, this is the right choice for either that nice weekend getaway you’ve been planning for quite some time, or for ensuring a quick response in case there’s some temporary power loss or emergency situation.

Fuel source

Since you need to keep this unit ready to be used at any given moment, the fact that it’s powered by unleaded gasoline is a convenient aspect. This also means you’ll easily find the right fuel source, even if you are not in an area you are particularly familiar with in terms of gas stations.

What this also means is that you can easily travel across longer distances and not fear that you’ll need a particular type of fuel that might not be available. For this reason, this model proves to be a trustworthy partner in your long-distance adventures.


Sound level

It’s true that generators might not be perceived as the most silent items that you can have around your home or camping site. However, given this model’s 91 pounds weight and 4000-watt power capability, we think that the decibel operation rating of under 69 dBA is a decent one that you will not perceive as being unbearable.

It’s true that if you are out in the wild, sounds can seem even louder, but even in these conditions, we are pretty sure that you will be pleased with this generator’s operating sound level.
