DESCRIPTION

10-Year LFP Battery,
Built To Last 6× Longer – Durable, Safe, Lightweight
With its upgraded LFP battery chemistry, DELTA 2 Max has a lifespan of 3000 complete cycles until it reduces to 80% capacity. You’ll get pretty much 10 years of power, even if you use it every day. That’s 6× longer than other power stations with a similar capacity and output.

Advanced BMS Protection
A built-in battery management system regulates vitals, including voltage, current, and temperature, keeping DELTA 2 Max safe, secure, and built to stand the test of time. Run 99% of Appliances with X-Boost – Power pretty much anything with up to 3100W Output
DELTA 2 Max powers almost all the devices you need with a large 2400W AC output. Plus, with X-Boost proprietary technology, run appliances with an output of up to 3100W. Compared with other power stations, DELTA 2 Max can power more devices, while still preventing overloading and overheating.

Power of the entire family – 2048Wh Capacity
A generous 2048Wh capacity makes DELTA 2 Max ideal for home backup, running your essentials for hours. With its lightweight design, DELTA 2 Max is portable enough to grab and go on the next camping trip.
*Data based on a 120W refrigerator.

Expandable up to 6kWh – Triple the power.
Take DELTA 2 Max with you anywhere as a solo unit or connect it with two Extra Batteries for up to 6kWh of home backup.
