## Description

Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, CARB Compliant Inverter Generator, ultra-lightweight and RV Ready, 4000-Watt Gray

Review: Lightweight Powerhouse! - Full disclosure- i've only owned this 4000W Duel Fuel generator for 3 weeks, but I've already had some good use from it and I've been very impressed thus far! I bought this to power my truck camper, and specifically my A/C on the truck camper when it's very hot. I had been carrying a 2000W Firman gas-only generator prior, and while I can run the A/C on the camper from that, it is nearly maxxed out when I do so I don't think I could run it for long if necessary, and there is the issue of carrying gas. The storage compartment of my camper requires laying the generator almost on its side to get it in/out of the compartment, and I've had gasoline leak into the compartment prior when doing so. No Bueno!! So I bought this generator, which is virtually the same size and weight as my Firman (which otherwise I've been very impressed with as well, btw) but allows me to operate from the on-board propane tanks located in my truck camper. It's clean and convenient to do so, and this generator runs pretty quietly given it can put out 3,200W continuously and 4,000 surge watts if necessary! It also produces a clean sine wave signal, so I don't have to worry about frying my cellphone, laptops, etc while charging. It is a few decibels louder than a Honda 2000i or 2200i, but close to 2 x's the output for a few decibels more. And at lighter loads on eco mode it is still very quiet (which is where it will operate most of the time I'm using it; less than 50% load.) I bought it and broke it in and tucked it away in the camper to take to the Sierra for one last skiing weekend, and lo and behold, it saved my butt when my diesel fuel gelled and I had to run the Pulsar for 3 hours to power my truck's block heater to get it started! My Firman could have handled the 700-800W draw as well, but again, nice to pull it out, hook it to the propane extension and fire it up. On that note, with propane I do need to give it a pull or two on choke before it starts on propane, but it runs perfectly once I do so. I'm at the 5 hour mark so I'll change the oil again tomorrow which should be the last maintenance I need for awhile. I really can't believe I found a propane generator with twice the capacity as my Firman 2k/1,600W gas generator for $500 (caught a sale on desertcart.) If my experience changes over time I'll update, but so far I'm very satisfied with this Pulsar Dual Fuel generator!
Review: Love it. - Love this inverter generator. Use it with my camper works great runs quiet.

## Questions & Answers

**Q: You see inverter generators with a "thd" percentage rating. what does this one have? also just to clarify if it's shipped in the us it has a 60hz?**
A: All Pulsar Inverters are sub-3% and typically well below that. At this threshold it is insignificant to all but scientific instruments.  Yes, of course our inverters output 60Hz,  -smile-  We are a California company!  Ring us up if you'd like to chat: 866.591.8921, we just opened.  -Tom

**Q: How long of a run time does it get per pound of propane (or per 20lb), and per gallon of gas; for full load and half load? Thanks,**
A: at half load, 4 hours with gasoline, 14 hours with 20lb propane tank

**Q: 1) does the motor have a steel sleeve in the piston cylinder  2) how will it be shipped. usps or ( ups or fedex) ?**
A: Our preferred carrier for GD400BN is FedEx.  I don't know about a cylinder liner.  I've been waiting 6 months for one to come back under warranty so I can investigate things like that. So far, the opportunity has not presented.   -Tom

**Q: which magnetic oil dip stick is compatible with the GD400BN**
A: I purchased the Wen model 55201 and it works fine.

### ⭐⭐⭐⭐⭐ Dependable and Quiet - A Must-Have for Outdoor Enthusiasts and Emergency Prep
*by N***N on February 23, 2024*

I recently purchased the Pulsar 2,300W Portable Gas-Powered Quiet Inverter Generator, and it has quickly become an indispensable part of my outdoor and emergency preparedness gear. From camping trips to backyard gatherings, this generator has proven its worth with its efficient, quiet operation and reliable power output. Efficiency Meets Portability: With 2,300 peak watts and 1,800 running watts, it strikes the perfect balance between providing ample power and being light enough to carry anywhere. Its fuel efficiency is remarkable, running up to 4.8 hours on a mere 1.18 gallons of fuel. Plus, its compact design makes it a breeze to transport and store. Clean, Safe Power for Sensitive Devices: I was particularly impressed with its stable sine wave technology, ensuring that my laptops, phones, and other sensitive electronics are safely powered without the risk of damage. This feature alone sets the Pulsar G2319N apart from many of its competitors. User-Friendly Design: The variety of outlets, including dual 120V, a 12V 'cigarette' outlet, and a USB port, offer convenient charging options for a wide array of devices and appliances. Its quiet operation is a game-changer, allowing for use in campsites and tailgates without disturbing the peace. Reliable Performance: My personal experience with this generator has been overwhelmingly positive. After a simple oil change to 5w30 full synthetic, it starts effortlessly, often on the first pull, and runs smoothly. Its performance and low noise level surpass other higher-priced models I've tried. Final Thoughts: The Pulsar 2,300W Portable Gas-Powered Quiet Inverter Generator is a fantastic choice for anyone needing a reliable, portable power source. Whether for recreational use or as a backup for small appliances during power outages, this generator delivers on its promises. The positive customer feedback and my own satisfactory experiences reinforce its value. While no product is without its flaws, the Pulsar G2319N stands out as a dependable and efficient generator worth considering.
