Weighing 30% less than typical generators, it’s designed for portability and convenience, featuring multiple outlets including RV-ready and USB ports.

The WEN® 4,000-watt inverter generator provides clean energy, free of voltage spikes and drops for safe use with laptops, phones, and other sensitive electronics. Designed to mirror a pure sine wave, this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load, making it safe to run sensitive electronics. Our ultra-efficient 1.85-gallon tank provides over seven hours of half-load run time. Maximize fuel economy by engaging the eco-mode switch. This allows the generator's engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel, preventing the unnecessary usage of gasoline. Need more energy? Easily link up two generators using a WEN® Parallel Connection Kit (sold separately) in order to share wattage amongst multiple units. Low-oil and low-fuel automatic shutdown combine with the built-in overload protection and indicator lights to safeguard both your generator and your electronics from damage. And because it's a WEN® product, your open frame inverter generator comes backed by a two-year warranty, a nationwide network of skilled service technicians, and a friendly customer help line, all to make sure you remember WEN®. ## Features - Generates clean power to safely operate sensitive electronics such as phones, tablets, TVs, and computers - Parallel-ready panel allows you to connect any 2 WEN inverter generators for increased wattage output - 212cc 4-stroke engine produces 4,000 surge watts and 3,500 rated watts - Lightweight body weighs 30% less than a standard 4000-watt generator - Includes two 120V NEMA 5-20R receptacles, two 5V USB ports, one 120V RV-ready TT-30R receptacle, and a two-year warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DJDR9H7Z | | Additional Features | Lightweight | | Best Sellers Rank | #26,542 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #117 in Outdoor Generators | | Brand Name | WEN | | Color | Orange | | Customer Reviews | 4.4 4.4 out of 5 stars (31) | | Engine Displacement | 212 cubic centimeters | | Engine Type | 4 Stroke | | Frequency | 60 hertz | | Fuel Type | Gasoline | | Ignition System Type | recoil start | | Included Components | Two 120V NEMA 5-20R receptacles, two 5V USB ports, one 120V RV-ready TT-30R receptacle, and a two-year warranty | | Item Dimensions L x W x H | 19.8"L x 13.8"W x 18.9"H | | Item Type Name | WEN RV-Ready 4000-Watt Open Frame Inverter Generator | | Manufacturer | WEN | | Manufacturer Part Number | GN400iM | | Material Type | Metal | | Model Name | WEN RV-Ready 4000-Watt Open Frame Inverter Generator | | Model Number | GN400iM | | Number of Items | 1 | | Number of Packs | 1 | | Output Wattage | 4000 | | Power Source | Fuel Powered | | Recommended Uses For Product | Camping, Residential | | Running Wattage | 4000 watts | | Runtime | 7 hours | | Starting Wattage | 4000 watts | | Tank Volume | 1.9 imperial gallons | | Total Power Outlets | 5 | | UPC | 044459140016 | | Unit Count | 1 Count | | Voltage | 120 volts_of_alternating_current | | Warranty Description | Two-year warranty | | Wattage | 4000 watts | ## Product Details - **Brand:** WEN - **Color:** Orange - **Fuel Type:** Gasoline - **Output Wattage:** 4000 - **Power Source:** Fuel Powered - **Recommended Uses For Product:** Camping, Residential - **Special Feature:** Lightweight - **Voltage:** 120 volts_of_alternating_current - **Wattage:** 4000 watts ## Images ![WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - Image 1](https://m.media-amazon.com/images/I/819rSLjaHuL.jpg) ![WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - Image 2](https://m.media-amazon.com/images/I/51RI7MrNxhL.jpg) ![WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - Image 3](https://m.media-amazon.com/images/I/419P4G0RZjL.jpg) ![WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - Image 4](https://m.media-amazon.com/images/I/51MhLYgfNrL.jpg) ![WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - Image 5](https://m.media-amazon.com/images/I/4152zz0jWXL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - WEN RV-Ready 4000-Watt Open Frame Inverter Generator (GN400iM) - WEN 55201 Magnetic Oil Dipstick for Inverter Generators (compatible with WEN, Yamaha, Predator) - WEN GNC400 Weatherproof Generator Cover for 4000-Watt Open Frame Inverter Generators --- ## 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.jp/products/677604087-wen-rv-ready-4000-watt-open-frame-inverter-generator-gn400im](https://www.desertcart.jp/products/677604087-wen-rv-ready-4000-watt-open-frame-inverter-generator-gn400im) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-17*
