Power When You Need It
EcoFlow DELTA 3 Max Plus is a high-capacity portable power station designed for dependable backup power, off-grid use, and mobile work. With a 2,048Wh LFP battery and 3,000W AC output, it provides strong performance for everyday devices while remaining compact enough to move where it’s needed.
It can be charged from mains power, solar panels, vehicle charging, or generator input, giving flexibility whether you’re preparing for outages, travelling in a campervan, or powering equipment on site.
For sensitive electronics, DELTA 3 Max Plus includes fast UPS switchover (approx. 10ms) and HID support, helping maintain power to computers, networking equipment, and other devices during short power interruptions.
Large Capacity with Expandable Power
DELTA 3 Max Plus includes a 2,048Wh lithium iron phosphate (LFP) battery, known for long cycle life and stable operation.
The system can also be expanded up to 10kWh with compatible EcoFlow expansion batteries, allowing capacity to grow depending on the application.
Powerful 3,000W Output
With 3,000W continuous AC output and up to 6,000W surge capability, DELTA 3 Max Plus supports a wide range of appliances and tools within its rated limits.
EcoFlow’s X-Boost technology can allow certain higher-wattage devices (up to 3,900W) to operate when supported by the device.
Note: X-Boost capability depends on the appliance and manufacturer guidance.
Fast Charging Technology
DELTA 3 Max Plus supports EcoFlow’s rapid AC charging technology.
-
AC charging: 0–100% in approximately 68 minutes
-
Generator charging: up to 2,400W AC input
