DELTA 3 Max Plus + 220W/400W/Extra Battery

Description

EcoFlow DELTALTA 3 Max Plus (2048Wh)

Powerful, Stable, Built for Anything

The EcoFlow DELTA 3 Max Plus delivers a robust 3000W AC output with a 6000W surge, giving you the confidence to power demanding appliances and critical systems. With X-Boost™ 3.0, it supports devices up to 3800W, making it ideal for home backup, job sites, and off-grid use.

Its advanced inverter continuously samples AC voltage and current every 33 microseconds using a high-precision DSP chip, producing a pure sine wave with grid-level stability. This ensures safe, reliable power for sensitive electronics, medical devices, and modern appliances.

Long-Lasting Power You Can Trust

Built with automotive-grade Full-Tab LFP battery cells, DELTA 3 Max Plus is engineered for durability, safety, and long service life. Internal testing estimates up to 10 years of dependable use with proper operation, backed by an intelligent battery management system (BMS) and rugged enclosure designed for demanding environments.

Fast, Intelligent Charging — Ready Before Emergencies Strike

DELTA 3 Max Plus supports five charging methods and up to 1800W AC input, reaching 0–80% in as little as 64 minutes under standard conditions. When paired with the EcoFlow Smart Generator 4000 (Dual Fuel), charging can reach 0–80% in approximately 43 minutes under optimal conditions.

EcoFlow’s Storm Guard Mode (via the EcoFlow App) monitors severe weather alerts and can automatically trigger remote AC charging, ensuring your system is ready well before an outage occurs.

Expandable Energy for Hours or Days

Scale your backup power from 2kWh up to 10kWh with Smart Extra Batteries, allowing you to cover short outages or extend runtime for multi-day emergencies.

Expansion configurations require:

• 1 × DELTA 3 Max Plus (2048Wh) + 2 × DELTA 3 Max Plus Smart Extra Batteries, or

• 1 × DELTA 3 Max Plus (2048Wh) + 2 × DELTA Pro 3 Smart Extra Batteries

Expansion requires the EcoFlow Smart Extra Battery Expansion Adapter (expected U.S. release around January 2026).

Hybrid Backup with Smart Generator Support

Pair DELTA 3 Max Plus with EcoFlow Smart Generators for virtually unlimited runtime. The system intelligently switches between battery and fuel power, making it ideal for extended outages, remote work, and off-grid living.

Smarter Monitoring, Total Control

Using the EcoFlow App, you can monitor battery status, energy usage, charging speed, electricity rates, and solar input from one intuitive dashboard. Some advanced app features will be released through future updates.
