Product Description
Power outages are unpredictable. Camping trips take you far from the nearest outlet. And a gas generator isn't an option when you're indoors, in an apartment, or setting up a campsite. The Ionic GenBox 400 is the portable power station built for those moments — reliable backup power you can take anywhere and trust when it matters.
The Right Amount of Power
The GenBox 400 packs 256Wh of LiFePO4 battery capacity, translating to real, practical runtimes: enough to keep a Wi-Fi router running for hours, power a portable fan through the night, or charge a laptop several times over. It goes well beyond standard power banks by offering a true 400W AC outlet that handles actual appliances and tools, not just USB devices.
Standard lithium-ion batteries begin fading after around 500 charges. The LiFePO4 cells inside the GenBox 400 are rated for 2,000+ full cycles, which amounts to roughly a decade of dependable use before you ever need to think about replacement.
Ready When the Grid Isn't
Keep the GenBox 400 charged in a closet and you're already ahead of the next blackout. When the lights go out, you can keep communication devices powered, run LED lighting safely indoors, and maintain overnight CPAP therapy without missing a beat. For maximum CPAP runtime, connect via the 12V DC port rather than the AC outlet to avoid energy conversion losses.
Recharging is just as flexible as the unit itself:
- Wall outlet: approximately 6 hours to a full charge
- 12V car port: recharge while you drive, no stop required
- Solar panel (sold separately): off-grid via the built-in MPPT controller
Pass-through charging lets you run connected devices at the same time you're recharging the station, so you're never stuck waiting for a full battery before using it.
Take It Anywhere
This isn't a generator that stays in the garage. At 8.81 lbs with an integrated carry handle, the GenBox 400 moves easily from room to room during a blackout or rides along in a gear bag on a camping trip. Zero emissions and silent operation mean it's equally at home in a bedroom, a tent, or the back of a van.
Storm season preparedness, weekend camping, van life, remote job sites — wherever you need reliable power without a cord, the GenBox 400 is ready. Order yours today and get free shipping on orders over $150.
Frequently Asked Questions
What can the Ionic GenBox 400 actually power?
A: The GenBox 400 can run any device drawing 400W or less continuously, with 800W of surge capacity for brief motor startups. That includes Wi-Fi routers, mini-fridges, portable fans, CPAP machines, LED lights, laptop chargers, cordless tool battery chargers, and small power tools. Devices like full-size microwaves (800–1,200W) or hair dryers (1,200–1,800W) exceed the unit's continuous output and are not compatible. When in doubt, check the wattage label on your device before connecting.
Does the GenBox 400 produce pure sine wave or modified sine wave power?
A: Based on the manufacturer's detailed FAQ, the GenBox 400 produces modified sine wave AC output. This works fine for most everyday devices — laptop chargers, LED lights, fans, phones, and basic appliances. However, some sensitive equipment (high-end audio gear, certain variable-speed motors, and some medical devices) performs better on pure sine wave. For CPAP users specifically, connecting through the 12V DC port instead of the AC outlet is strongly recommended — it bypasses this concern entirely and extends your runtime. If your equipment requires pure sine wave, the GenBox 800 is designed for that. Note: The specification sheet lists "pure sine wave" — we recommend confirming the output type directly with the manufacturer before purchasing if this is a deciding factor.
What is the best way to use the GenBox 400 with a CPAP machine?
A: Use the 12V DC port (the car-style outlet) rather than the AC outlet. Powering a CPAP directly via DC avoids the energy conversion losses that come with AC delivery, extending runtime to approximately 6–8 hours per charge. Many CPAP machines support a 12V DC travel cable — check your CPAP manufacturer's accessories or documentation to see if one is available for your model. For the longest possible runtime, disable the heated humidifier and heated tubing if you don't need them, as those features significantly increase power draw.
Can I use the GenBox 400 while it's recharging?
A: Yes. The GenBox 400 supports pass-through charging, so you can power connected devices while the unit is recharging via the AC wall adapter, 12V car port, or solar panel input. This is especially useful during extended outages or on road trips where stopping to wait for a full charge isn't practical. There is no need to disconnect your devices before plugging in the GenBox 400 to recharge.
