EcoFlow DELTA 3 Max (2048Wh)
Serious Power for Demanding Loads
EcoFlow DELTA 3 Max delivers 2400W of rated AC output and, with X-Boost™ 3.0, supports devices up to 3400W, making it ideal for heavy-duty appliances and sensitive electronics alike. Its advanced inverter samples AC voltage and current every 33 microseconds using a precision DSP chip, producing a pure sine wave with grid-level stability for safe, reliable performance.
Fast, Intelligent Charging — Ready in Just 68 Minutes
With up to 1800W AC input, DELTA 3 Max charges from 0–80% in as little as 68 minutes under optimal conditions using X-Stream fast charging.
EcoFlow’s Storm Guard Mode (via the EcoFlow App) monitors severe weather alerts and can automatically initiate remote AC charging—so your system is ready before an outage hits.
Built to Last for Emergencies and Everyday Use
Powered by automotive-grade Full-Tab LFP battery cells, DELTA 3 Max is designed for long-term durability and safety. A rugged enclosure and intelligent Battery Management System (BMS) provide real-time monitoring of battery health, temperature, charge status, and performance—helping ensure up to 10 years of reliable operation with proper use.
Compact, Portable, Lighter Than Ever
Weighing just 20.3 kg (44.8 lb), DELTA 3 Max is 13% lighter than the DELTA 2 Max, making it easier to transport without sacrificing power. Its compact design fits seamlessly into homes, RVs, worksites, and outdoor setups.
Smarter Control, Deeper Insights
