We have been having single digit temperature weather and I have been able to get the generator started relatively easy to run the block heater on my truck. Truck is parked far enough from an outlet that it's easier to turn on the generator to get power by the truck that way. When power went out it was also great to have the electronic safe power that this provided. Starlink internet kept the home entertained, the generator ran other electronics, and propane kept us heated. Overall, still very happy with the generator. Have not run the generator on gas, only have ran mine on propane. Generator ships with all you need to get started, except the fuel source. Oil funnel is also used to drain the oil. Makes it very mess free for oil changes. Which I recommend changing after the first hour, since there's all kind of glitter in the first oil change. I then ran it another couple hours and changed again. Much cleaner this time. Holds 15 ounces of oil so a standard quart of oil can do two oil changes. In total I changed the oil three times during the break in before switching in full synthetic oil. It runs very quiet and stays pretty quiet under load. Quieter than a smaller 700 watt inverter generator I have and while not as fuel efficient it is still very economical with how much propane it uses. Revs up to produce power and has run my 10,000 btu window ac without issue. Ran a 5,000 btu and small .7 cubic foot microwave at the same time off of it. I love the size of this unit for the amount of power it produces. You can parallel two of them if you need more power. Really the only downsides I have would be no electric start, and the outlet selection is sparse. Got mine with coupon off of desertcart and have no regrets so far. Will update if anything negative happens 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! ## Features - 4000 peak watts / 3200 running watts on gas - 3700 peak watts / 3000 running watts on propane - Continuous operation up to 4.5-hours at half load (1.1 Gallon Fuel Tank) - Ultra lightweight at only 47.3 pounds, ideal for outdoor activity use - Super quiet, making around 59db at half load - High speed 5.5HP 145cc engine, good for emergency home backup power - Safely power sensitive electronics such as televisions, cell phones, laptops, and more ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BHXLT5D9 | | Additional Features | Dual Fuel | | Brand | Pulsar | | Brand Name | Pulsar | | Colour | 4000w Dual Fuel Inverter Generator | | Customer Reviews | 4.2 out of 5 stars 395 Reviews | | Engine Displacement | 145 Cubic Centimetres | | Engine Type | 4 Stroke | | Frequency | 60 Hz | | Fuel Type | propane | | Included Components | Inverter generator | | Item Type Name | Inverter Generator | | Item Weight | 47.3 Pounds | | Manufacturer | Pulsar | | Manufacturer Part Number | GD400BN | | Material Type | PVC | | Model Name | GD400BN | | Model Number | GD400BN | | Output Wattage | 4000 | | Power Source | gas-powered | | Runtime | 4 hours | | Tank Volume | 1.1 Gallons | | UPC | 814726027803 | | Voltage | 120 Volts (AC) | | Wattage | 4000 Watts | ## Product Details - **Brand:** Pulsar - **Wattage:** 4000 Watts - **Fuel Type:** propane - **Power Source:** gas-powered - **Item Weight:** 21.46 kg - **Voltage:** 120 Volts (AC) - **Output Wattage:** 4000 - **Special Feature:** Dual Fuel - **Included Components:** Inverter generator - **Colour:** 4000w Dual Fuel Inverter Generator ## Images ![Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Image 1](https://m.media-amazon.com/images/I/71hFcELrhoL.jpg) ![Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Image 2](https://m.media-amazon.com/images/I/718WRVYRbkL.jpg) ![Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Image 3](https://m.media-amazon.com/images/I/71iJRO7UoRL.jpg) ![Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Image 4](https://m.media-amazon.com/images/I/713K3h7zJ8L.jpg) ![Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Image 5](https://m.media-amazon.com/images/I/91to4IlECiL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Efficient, Small, Quiet, and Capable *by G***N on 27 August 2023* *Update 1/17/24* Still working great, still running it only on propane.

Tries to start over many days using different propane sources and connections. Occasionally would almost start, but it sputtered to a stop immediately. Overload light would blink on with nothing plugged in, and the engine would stop sputtering. Reached out to Pulsar customer service by email. They asked for a video of me attempting to start it, which I sent immediately. Their response multiple days later was it was a warrantee issue, and I had to prove that this product I just purchased but never worked was still covered under warrantee. Tried to return it and was told it could not be returned. Cannot recommend this product or Pulsar's customer service. ## Frequently Bought Together - Pulsar Products GD400BN, 4000W Portable super-quiet Dual Fuel & Parallel Capability, RV-Ready, CARB Compliant - Larlansz Magnetic Oil Dipstick for SMALL Inverter Generators Compatible with Wen 55201 Yamaha Predator 2000 Westinghouse champion Ai power Generac pulsar - Magicalmai Inductive Hour Meter for Gas Engine Generator Lawn Mower Pressure Washer Marine ATV Boat Outboard Motor Dirt Bike Motorcycle Waterproof Hr Meters - Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/728192586-pulsar-products-gd400bn-4000w-portable-super-quiet-dual-fuel-parallel](https://www.desertcart.vn/products/728192586-pulsar-products-gd400bn-4000w-portable-super-quiet-dual-fuel-parallel) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
