Wen 3800 watts generator- An overview:

WEN 56380i can produce enough power to run all the essential electrical appliances. A potent 212cc engine can provide a starting wattage of 3800W and running wattage of 3400W. The eco-throttle mechanism will reduce the engine's RPM depending on the loads connected to the generator. Therefore, the engine is quiet in operation with an increased life span. This generator will produce a sine wave with less than 1.2% THD (Total Harmonic Distortion). So, it is safe to supply power to sensitive electronics. You can start the generator either with a manual recoil or an electrical push button. An LCD on the generator will show the parameters like the frequency, current load, fuel level, and runtime. Thus, the operator can schedule the maintenance periodically. An automatic fuel shutoff system utilizes the fuel remaining in the carburetor before the engine comes to a halt. 

In addition to this, it is very easy to change the oil with the help of an oil cover. The spark arrestor will prevent the sparks from escaping outside the generator so that you can use this generator in forecast areas without any risk of fire accidents. Moreover, you can easily port the generator from one place to another with supported wheels and handlebars. This gasoline generator produces a high-level noise of 57 decibels, which is the sound of a normal conversation ( a whisper is 30dBA and motor engine running is 95dBA). The 2.2-gallon tank can give a runtime of 8.5 hours at applied load. The weight of the generator is about 110.80 pounds. A generator cover is available. This cover makes the generator weather-resistant and protects from UV rays. The interior of the generator is cotton made to prevent scratches. 

Special features:

When the fuel level is low, the fuel shutoff system uses the fuel inside the carburetor before the engine seizes. The inverter technology employed in this model can provide clean power, which prevents the damage of electronic appliances while charging. A digital display helps you check the fuel level at a glance. If you plan to travel across the country in an RV, you need a good backup generator that can charge up your necessary amenities. This Wen generator will be suitable for your RV. Besides, it is also equipped with a spark arrestor, so it is safe to use in parks and forests. If you are looking for higher wattage than the previous model to charge many devices, this Wen 3500 watts generator is perfect for you. The THD of this generator is less than 1.2%, so they are suitable for charging sensitive electronics like smartphones, laptops, etc. 

The design:

This generator comes with a manual, and it also comes with a small tool kit to open the generator during repairs. It comes with a couple of nice-sized wheels better than some that I've seen on the market. The first thing you need to do is charge the battery as it generally comes fully drained. Because the battery compartment is relatively small so I had to take off the side compartment door. The dimension of the generator is 23.2 x 18 x 20.1 inches. It is compact enough to fit into your RV or the back of your car during travel. This generator weighs around 110 pounds, so it is easy for you to carry them in your vehicle. You cannot lift it single-handedly, so you probably need a company to carry them. The generator's color is standard orange-black.

Charging your generator batteries:

These new generators are coming with lithium-ion batteries, which is a definite bonus. Some of them are still coming with lead-acid. So we're going to take our ground cable and hook it up to the battery. That way, we can get this thing further along and get our oil in it, and then we can get on to firing it up and getting it tested. So one thing again, due to the little compartment, it is challenging to get this battery in and out of here. This generator just needed a little more room; then, it would have been a lot easier. So I had to feed the cables through the back, and then basically what I had to do is, I took these battery cables, and I had to put him on the other side of the intake because there is just so much slack.

Handy outlets:

The orange button that starts it up goes into the run position. After we let it run for a little bit and then go into the auto-off, drain the fuel out of the carburetor, shut off within a minute or two, or use a little red manual shutoff button. There you have your data meter up top. There is a reset button-up top that doesn't have a weather-protected cap. Not sure why. And then you can see it has a 30 or V. plug on. A 30 amp RV plug with a couple of parallel ports. Suppose you want to run these together with the 12-volt socket for some of your other accessories and a dual U. S. B. port down below with the running either one or 2.one amps.

Uses of this generator:

You can use this generator for both indoor and outdoor purposes. You can light up your home, charge your fridge and even heat some food from your microwave. It has less than 1.2% of total harmonic distortion so that you can charge sensitive electronics too. And if you are planning to go on a daily trip or camping, you can take this generator with you since it is portable and has enough wattage to charge your RV. So if you are planning to buy a generator for both home and travel use, I suggest this Wen 3800 watts generator. 

Few things Wen can improve:

Given the price and features, the Wen 3800 watts generator is the best choice for anyone looking for a portable inverter generator. But there are few things I think the Wen generator can improve. Firstly, it would be very helpful if the generator had a remote start option. Some generators (like Champion 75537i) have this feature, and it would be very helpful if Wen implemented them. The exterior material of this generator also feels a little clumsy. So you should be very careful about how you lift and place them. 

Why we love Wen 3800 watts generator:

  1. It provides clean power with less than 1.2% THD. 
  2. The noise level of this generator is 57 dBA, so it is super quiet. 
  3. This generator is RV-ready. 


On the whole, the Wen 3800 watts generator is the best bargain when it comes to portable inverter generators. It has everything you look for in a portable generator. It is RV-ready, has an electric start option, is super quiet, and is very easy to maintain. If you are looking for a lesser wattage generator, Wen also has 2000 and 2250 watts generators.
