The UDPOWER S2400 is a flagship energy solution from UDPOWER, an emerging brand making a serious statement in the portable power space with cutting-edge battery technology, whisper-quiet operation, and a feature set that punches well above its price point. Designed for campers, homeowners, outdoor professionals, and emergency preparedness, it delivers high-capacity, gas-free power in a surprisingly compact and carry-friendly package.

Power for Demanding Appliances

With 2083Wh of LiFePO4 capacity, 2400W of continuous pure sine wave output, and UDTURBO surge support up to 3000W, the S2400 has the muscle to run microwaves, induction cooktops, refrigerators, and power tools without hesitation.

16 Ports, One of the Most Versatile Arrays in Its Class

Sixteen simultaneous outputs include 6 AC outlets, 4 USB-A ports, 2 USB-C ports (up to 100W with PPS), 2 DC5521 ports, a 12V car outlet, and 15W wireless charging. Plug in everything at once.

Four Ways to Recharge

Charge from an AC wall outlet with Super Fast Charge, going from 10% to 90% in just 40 minutes. You can also use solar input up to 400W, car charging at 120W, or a gas generator for true off-grid redundancy.

Seamless UPS Backup

UPSPRIME UPS technology switches over in 10ms or less, keeping your router, security system, PC, or medical equipment running the moment the grid goes down. It switches back automatically when power returns.

Whisper-Quiet Operation

A noise-insulated battery compartment and dual-flow cooling system keep noise under 20dB. It is silent enough for indoor use, bedrooms, and overnight camping without disturbing a soul.

Built to Last Over a Decade

Brand-new Grade-A LiFePO4 60130 large tabless cells, UL-certified and automotive-grade, deliver 4000+ charge cycles with 80%+ capacity retention. That is well over a decade of regular use.

Smart, Certified Safety

The AI-level battery management system runs 84 rigorous internal tests, 64 real-time safety monitoring items, and 10 temperature sensors. A flame-retardant UL 94 V-0 enclosure and certifications including UL2743, FCC, RoHS, and UN38.3 add further protection.

Portable and Backed by the Brand

At just 40.8 lbs and 15.8″ × 9.5″ × 10.1″, with a built-in handle, it is remarkably portable for its output class. Zero self-discharge standby mode keeps it ready for long-term storage. Every unit comes with a 5-year warranty, 30-day returns with a provided return label, free shipping to the 48 contiguous states, and a tree planted for every order.

A Complete Portable Energy Ecosystem

From powering a campsite to protecting your home essentials during an outage, the S2400 delivers intelligence, safety, and endurance that used to cost twice the price. Massive power. Whisper-quiet. Built smarter.
