EcoFlow DELTA Pro Portable Power Station

EcoFlow DELTA Pro is a 3,600Wh portable home battery built for outage backup, RV and off-grid living, and job-site power. Five AC outlets deliver 3,600W of pure sine wave power, and the system expands with extra batteries, a second DELTA Pro and EcoFlow's home-integration accessories as your needs grow.

Output for Heavy Loads

A single DELTA Pro delivers 3,600W continuous with 7,200W surge, and X-Boost mode runs devices rated up to 4,500W. Pair two units with the Double Voltage Hub for up to 7,200W. Fifteen output ports (five AC outlets, four USB-A including two fast-charge, two 100W USB-C, a car outlet, two DC5521 ports and a 30A Anderson port) handle appliances, tools and electronics at the same time.

Fast, Flexible Charging

• AC: 1,800W at 120V (about 2.7 hours) or 3,000W at 240V (about 1.8 hours)
• Solar: up to 1,600W, 11–150V, 15A via XT60 (about 2.8–5.6 hours)
• EV station: up to 3,400W with the EcoFlow EV X-Stream Adapter (about 1.7 hours)
• Vehicle: 12V/24V battery systems, 8A
• MultiCharge: up to 6,500W combined input when charging DELTA Pro and an extra battery together using AC, solar and Smart Generator sources

Expandable Capacity

Add up to two DELTA Pro Smart Extra Batteries for 10.8kWh, or build a system of two DELTA Pro units and four extra batteries for up to 21.6kWh. DELTA Pro also works with the EcoFlow Smart Generator, Smart Home Panel, Double Voltage Hub, DELTA Pro Remote Control and EV X-Stream Adapter.

Long-Life LFP Battery

Lithium iron phosphate cells are rated for 3,500 cycles to 80% capacity and 6,500 cycles to 50%. The integrated battery management system protects against overvoltage, overload, overtemperature, short circuit, low temperature, low voltage and overcurrent.

Home Backup and Control

Emergency power supply switchover takes approximately 30 ms. The LCD shows battery level, remaining time, input and output power and warnings, while the EcoFlow app (Wi-Fi and Bluetooth) lets you monitor the unit, switch AC and DC outputs, adjust AC charging speed and update firmware. Integrated wheels and a retractable handle make the 99 lb unit practical to move.

Common Questions

Can DELTA Pro run 240V equipment?

The US DELTA Pro outputs 120V. For 240V, connect two DELTA Pro units through the Double Voltage Hub, or through the Smart Home Panel to your home's 240V circuits (requires 240V wiring at installation).

How many solar panels can I connect?

You can combine MC4-connected panels as long as the array's combined voltage stays within 11–150V and current stays under 15A.

Can I charge from a 240V outlet?

Yes, at up to 3,000W. The included AC charging cable fits standard 120V outlets, so a compatible 240V cable or adapter is required.

How do I update the firmware?

Connect DELTA Pro to the EcoFlow app in Internet mode, open the device settings and follow the steps in the Firmware section.
