Power outages, remote job sites, weekend RV trips, mobile coffee trucks — they all have one thing in common: they need dependable power, on demand. The NEJoye X4000 portable power station delivers a true 4000W continuous output (6000W peak) from a 3456Wh lithium iron phosphate battery, with pure sine wave AC, sub-15ms UPS backup, and five charging inputs that include solar and EV charging piles. It's the 4000W portable power station built to keep your home, business, and adventures running — no matter where the grid ends.

Whether you need a home backup power station, an off-grid solar generator for a cabin or van, or reliable electricity for a food truck or construction site, the X4000 is engineered to be the only power source you'll ever need. Here's why.

True 4000W Output — 6000W Peak, Pure Sine Wave

Most portable power stations quote impressive peak numbers but can't sustain real loads. The NEJoye X4000 delivers a genuine 4000W rated output (3600W on 100–120V grids) through its four universal AC outlets, with a 6000W peak that handles surge-heavy appliances with ease. Refrigerators, air conditioners, water heaters, power tools, coffee machines, and industrial equipment — the X4000 starts them and keeps them running.

The four AC outlets are arranged in a 2×2 grid and accept international plug types, so the X4000 works whether your market runs on US, EU, or UK sockets.

Pure Sine Wave — Safe for Sensitive Electronics

The X4000's AC output is true 220V pure sine wave, matching the quality of grid electricity. That means it won't damage your appliances — laptops, TVs, medical devices, audio equipment, and CPAP machines all receive clean, stable power, free from the choppy modified waveforms that can harm sensitive electronics over time.

3456Wh LiFePO4 Battery — Built for Years of Service

At the core of the X4000 sits a 3456Wh battery pack built with lithium iron phosphate (LiFePO4) cells — the chemistry trusted in electric vehicles for its thermal stability and safety. LiFePO4 doesn't catch fire or explode under stress, and it delivers thousands of charge cycles before degradation, making the X4000 a long-term investment rather than a disposable gadget.

Works in Extreme Conditions

The X4000 operates reliably from -20°C to +40°C, so it performs in freezing winter outages, scorching summer job sites, and everything in between. Whatever the weather throws at it, the X4000 keeps delivering.

8-Layer Protection — Safety That Never Sleeps

A powerful battery needs a powerful guardian. The X4000's intelligent battery management system provides 8-fold protection, covering every failure mode that matters:

● High-temperature protection

● Low-temperature protection

● Over-discharge protection

● Overload protection

● Short-circuit protection

● Overvoltage protection

● Overcurrent protection

● Battery protection

Every charge and discharge cycle is monitored continuously, protecting your devices, your battery, and your property — automatically.

Recharge Every Way: 2200W AC, 2000W Solar, EV Pile

The X4000 accepts power from virtually any source, so it's never stranded for long:

●  AC mains input: up to 2200W fast charging

●  Solar input: up to 2000W (MPPT)

●  EV charging pile input: up to 2000W

●  AC + solar combined: up to 4000W

●  EV pile + solar combined: up to 4000W

With fast charging from the wall and the ability to charge from an EV charging pile on the road, the X4000 refills quickly wherever you are — and can even combine AC and solar inputs for a combined 4000W charging speed.

Solar-Ready — MPPT 12–150V

Pair the X4000 with solar panels and it becomes a true solar generator. The MPPT controller accepts a wide 12–150V input range at up to 40A, pulling maximum energy from your panels in almost any light. From four foldable panels at a campsite to a fixed rooftop array, the X4000 turns sunshine into stored energy — silently and sustainably.

11 Devices at Once — 5 Types of Interfaces

The X4000's interface is designed for real-world chaos. With 5 types of output interfaces, it can charge 11 devices simultaneously:

●4× AC outlets (220V, 4000W rated / 6000W peak)

●2× USB-C ports — up to 100W PD fast charging for laptops and tablets

●2× USB-A ports (5V 2.4A) +

●2× USB-A QC ports (up to 18W)

●1× 12V car outlet— up to 120W for car appliances

Espresso machine, air fryer, projector, cameras, phones, tablets, massage guns, drones — plug them all in at once. The thoughtful layout distributes ports so every device gets the power it needs, no juggling required.

UPS Backup — Sub-15ms Switchover, Zero Downtime

The X4000 doubles as a serious uninterruptible power supply (UPS). When the grid drops, it switches to battery in less than 15 milliseconds — fast enough to keep computers, servers, and network equipment running without a single interruption. No lost files, no corrupted data, no downtime. For home offices, clinics, and enterprise workstations, the X4000 is a complete backup solution in one box.

Smart Control: Touchscreen, ECO Mode, Silent Mode

Operating a 45kg power station should never be complicated. The X4000's touchscreen display puts every function at your fingertip — battery status, input/output wattage, and mode settings in a clear, intuitive interface.

●ECO mode extends standby time and minimizes battery wear when full output isn't needed

●Silent mode delivers no-noise, no-exhaust operation — perfect for indoor use and quiet campsites

Expandable Power — Parallel Up to 21.6kWh

One X4000 is already powerful. Need more? The X4000 supports parallel connection, so you can link multiple units — or connect an expansion battery pack through the dedicated interface — to scale your capacity on demand. Connect six units and the system reaches up to 21.6kWh of stored energy, enough to back up a small business or power an off-grid homestead for days.

Built to Move — Ergonomic Design

The X4000 is designed to be moved by one person. Two heavy-duty handles with textured orange grips make lifting easy, while large rear wheels and a telescopic handle let you tilt and roll the unit like premium luggage. From the garage to the job site, from the truck to the campsite, the X4000 goes where you go. At approximately 540×490×300mm and 45kg, it packs serious capacity into a manageable footprint.

One Station for Every Scenario

The X4000 is built to satisfy nearly every electricity scenario — a single all-in-one machine for:

●Home backup — keep the lights, fridge, and CPAP running through outages

●RV and mobile living — power your RV appliances and mobile power needs on the road

●Mobile business — food trucks, coffee carts, and market stalls with electricity anytime

●Outdoor work — surveying, maintenance, emergency rescue, and security operations

●Enterprise backup — UPS protection so employees keep working and data never disappears

●Off-grid areas — islands, fish farms, yurts, and remote zones with no grid access

●Camping — solar-recharged power for tents, cookers, projectors, and lanterns

Frequently Asked Questions

How long will the X4000 run my appliances?

As a rule of thumb, divide 3456Wh by the wattage of the appliance. A 400W refrigerator runs for roughly 7 hours; a 100W LED lighting setup runs for almost 29 hours. High-draw tools and appliances reduce runtime proportionally.

Can I charge the X4000 with solar panels?

Yes. The X4000 accepts up to 2000W of solar input with a wide 12–150V MPPT range, and it can combine solar with AC or EV-pile input for up to 4000W total charging.

Can the X4000 power a food truck or mobile business?

Absolutely. With 4000W rated output, 6000W peak, and 11 simultaneous devices, it runs espresso machines, freezers, griddles, and cash registers — a complete mobile business power solution.
