Pulsar Products GX400BN, 4000W Portable Ultra-Quiet Dual Fuel & Parallel Capability, RV-Ready, Handle & Wheels, with CO

I had a WEN Gen Duel Fuel i4000w and Loved it. I became ill and was not able to lift it. #1 PUT REGULAR OIL IN IT. THEN MAKE SURE YOU RUN UNIT 30-40 MINUTES with medium load and idle !! CHANGE THE OIL !! Then Run unit again 30-40 minutes half to medium load. THEN CHANGE ( Look for Metal Flakes in oil ) if good drain and refill with the oil of choice( I like Valovine Motorcycle synthetic 10-30. If Flakes still visible Run as many times as necessary to remove all flakes ( average 3-4 times ) This Eliminates head aches and major problems down the road or off road.I used this Pulsar 4000 for a 34’ rv dual AC, two refrigerators 120 & 12v this unit WILL run one AC 15,000 btu’s 1690 run watts along with several other appliances. Very Pleased Just Wished It had Push Start. 5- Stars. Quality Workmanship Pull Handle , wheels and easy to MOVE Around , oWeight 60#’s Stores NICELY. REMEMBER PREMIUM FUEL WITH STABILIZER.GREAT COMPACT GENERATOR GREAT VALUE FOR YOUR MONEY. PLENTY OF POWER AND A LOW NOISE LEVEL

Light weight and extremely nice generator. Some have mentioned rough idle or rough low speed, I have not had that issue. So far it has been trouble free. I have only run it on propane so we can keep it stored in an enclosed trailer.

I purchased this mainly for our camper to run the AC and other items on the RV.I really like the power and how compact it is. Works great on propane. I have yet to use it with gasoline. I like that the receptacle matches the plug so no adapters needed.Some things I do not like.1. I cut my nail nearly off when pull starting. My finger caught the chrome bezel and it tore a chunk of nail off. I am more careful now.2. It rattles. The handle rattles and makes a horrendous noise so I just prop something under the handle. I think the wheels rattle too but do not appear to be as bad, tolerable.3. The display is good but very confusing and possibly not even accurate. As I toggle through the modes the hour meter does not seem to change. Maybe over time it will make more sense. If not I will put my own hour meter on it.At this point I would recommend and buy again.

For the price it is well worth it.

This generator is great propane/gas. I'm using it for propane only to keep it smelling clean and storing indoors. Set up was simple take out of box, add oil plug in the propane cable turn on and set to choke and pull cable. Easily started within 5 pulls. I heard it starts easier on run with propane instead of choke. This generator is light about 50 pounds and has wheels to make it extremely portable. It's not loud either I ran it in my back yard and can barely hear it from the front yard. Ready the next time my power goes out!

This replaced 2 Honda EU2000s (parallel’s) for operating a Thermoking reefer in a Sprinter Van. I don’t have exact consumption rates on propane yet but I expect it to be around 23-25 hours on load of 40% average.I’m rating it a 5 at this time because I now have over 200 hours total run time with no issues. If it fails before I hit the 1000 hour point, I’ll adjust downward 1-2 stars. At 2000 hours (.299 per hour acquisition cost) I’ll consider it a success.

Do not purchase the GX400BN 4000 watt generator. We were going camping the Labor Day weekend. Took it out of the box, put oil in it and put gasoline in it. Set all the buttons and pulled the cord, and I pulled the cord, over and over, would not start. Waited until Tuesday to call them. Their customer service is a joke also. I talked to a person who told me to do this and do that and even hooked it up to propane and it never would start. She wanted me to give her the serial number of the generator. It was not on the machine, it was not on the box. She told me it was also to the left of the oil dipstick on the motor. There was no serial number I could find. I told that to the second person also. Once again I found no serial number. So I would not purchase the pulsar 4000 watt generator.

Issue was resolved by warranty. The tech service dept and customer service was outstanding. I would recommend the brand just based on my experience with needing support.Replacement Genny runs as expected, it's a good value and provides decent amount of power for its size.Engine ran as expected on propane for one hour, changed the oil, and the Pull start cord pulled right off machine on the second attempt to start (with very little force). Machine had not even been put under load yet and it's useless.0% quality control on this new product. Extremely disappointed in Pulsar. Impossible to troubleshoot or repair without dissambling the entire unit.Unbelievable
