Battery Specifications

• Capacity: 2,048 watt-hours (2.048 kWh)

• Chemistry: Lithium Iron Phosphate (LiFePO₄)

• Cycle Life: Approximately 3,000 cycles to 80% capacity

The use of LiFePO₄ battery technology ensures extended lifespan, excellent thermal stability, and improved safety. Even after daily use over several years, the battery retains most of its original capacity. This chemistry also minimizes degradation under repeated charging, making it suitable for both everyday and infrequent emergency use.

Power Output and Inverter Capabilities

• Rated AC Output: 2,400 watts continuous

• Surge Power: Up to 4,800 watts with X-Boost technology

• Inverter Type: Pure sine wave

With its 2,400-watt output, the DELTA 2 Max can power virtually any household appliance, including air conditioners, kettles, microwave ovens, electric stoves, vacuum cleaners, and power tools. The pure sine wave output ensures clean power for sensitive electronics like medical devices, servers, and communication equipment.

Output Ports

The DELTA 2 Max includes a full suite of outputs to support a variety of devices and appliances:

• AC Outlets: 4 x 120V (or 230V depending on region)

• USB-C Ports: 2 x 100W

• USB-A Ports: 2 x standard, 2 x fast-charge

• Car Outlet: 1 x 12V/10A car socket

• DC5521 Ports: 2 x 12V/3A

This configuration enables simultaneous operation of high-demand appliances alongside lower-wattage devices such as laptops, drones, routers, cameras, and LED lights.

Charging Methods and Speed

The DELTA 2 Max is designed for extremely fast and flexible charging through multiple sources:

1. AC Charging: Charges from 0 to 100% in about 81 minutes with X-Stream fast-charging technology.

2. Solar Charging: Accepts up to 1,000 watts of solar input with MPPT control, allowing full recharge in approximately 2 to 3 hours under optimal sunlight.

3. Car Charging: Compatible with 12V and 24V vehicle ports, suitable for recharging during travel.

4. Smart Generator: Supports direct charging from the EcoFlow Smart Generator for extended off-grid runtime.

The unit’s high charge input capacity makes it one of the fastest-recharging power stations in its class.

Expandability

The DELTA 2 Max supports connection to additional battery modules for extended capacity:

• Extra Battery (same model): Increases capacity by 2,048Wh per unit

• Total Capacity (with two extra batteries): Up to 6,144 watt-hours

This makes it capable of sustaining full-sized household devices or multiple workstations for many hours or even days.

Build and Design

• Weight: Approximately 23 kilograms (about 50.7 pounds)

• Dimensions: Roughly 49.7 x 24.2 x 30.5 centimeters

• Build Material: High-durability plastic housing with internal metal reinforcement

Despite its capacity and power, the DELTA 2 Max maintains a manageable size for transport in vehicles or storage at home. Integrated handles on both sides support two-handed lifting, and the design includes ventilation and cooling fans to manage heat under heavy load.

Display and Monitoring

The unit features a front-facing digital screen that displays:

• Battery percentage

• Input/output wattage in real time

• Estimated time remaining to full charge or depletion

• System alerts and temperature indicators

For remote monitoring, the DELTA 2 Max connects to the EcoFlow app via Bluetooth or Wi-Fi. The app allows users to monitor power usage, control ports, schedule charging, and update firmware.

Safety Systems

A sophisticated battery management system (BMS) provides layered protections:

• Overvoltage and undervoltage protection

• Overcurrent and short-circuit protection

• Temperature regulation

• Cell balancing

• Overload shutdown and warning alerts

The DELTA 2 Max also includes Emergency Power Supply (EPS) capability. While not a true uninterrupted power supply (UPS), it switches to battery mode within about 30 milliseconds, fast enough to keep most electronics running without interruption.

Use Case Scenarios

• Home backup power: Run essentials like a refrigerator, Wi-Fi router, lights, fans, laptops, and medical devices during blackouts.

• Outdoor recreation: Power camp kitchens, mini-fridges, drones, and lighting while camping or overlanding.

• Professional workstations: Operate tools, computers, lighting, or video equipment on construction sites, film sets, or field locations.

• Off-grid living: Provide a primary or backup power source for cabins, RVs, or remote outposts with solar charging.

Limitations and Considerations

• While powerful, continuous loads above 2,400 watts will require either load management or may trigger overload protection.

• Solar charging requires separate solar panels and can be affected by weather and panel placement.

• EPS switching time may not be sufficient for critical systems like some medical life-support devices.

• Weighs more than smaller units and may not be practical for foot transport.

Conclusion

The EcoFlow DELTA 2 Max is a flagship-level portable power solution that combines high power output, rapid recharging, and modular expandability. With support for high-wattage appliances, long-lasting LiFePO₄ battery chemistry, and advanced connectivity features, it suits demanding home users, professionals, and off-grid enthusiasts alike. Whether used as an emergency power hub, solar-powered backup, or field work solution, the DELTA 2 Max delivers long-term reliability and performance.
