The top tier of mobile power stations
The EcoFlow Delta Pro 3 plays in a different league from 1 kWh models: 4096 Wh of LiFePO4 capacity and 4000 W of continuous power. At this level, we are no longer talking only about leisure, but about keeping serious equipment running for a long time.
When to choose it
At home
It can act as a backup source for a workshop, a freezer, a heating system with low electrical consumption or a full computer workstation. Connecting it to a home electrical panel nevertheless remains a job for a qualified installer.
On a building site or at an event
Drills, saws, lighting, sound systems: the 8000 W peak rating can feed demanding tools. Each device must still be tested, because start-up current is specific to each motor.
In a fitted-out vehicle or an off-grid cabin
Combined with solar panels, it forms the core of a medium-sized off-grid power supply.
What you can plug in
- 4 x 230 V AC sockets (Schuko).
- 2 x 18 W USB-A ports.
- 2 x 100 W USB-C ports.
- 1 x 12.6 V, 30 A DC output.
- Wi-Fi and Bluetooth.
Recharging: two powerful inputs
The mains charging port reaches 2900 W, with a range of 30 to 150 V and 15 A for 1600 W maximum on one side, and 11 to 60 V and 20 A for 1000 W maximum on the other. The stated mains recharge time is about 2 hours. These ranges are precise: any panel or source connected must stay inside them, and the mounting conditions (cables, connectors) should be confirmed with the manufacturer.
Footprint and handling
The case measures 693 mm x 341 mm x 410 mm and weighs around 51.5 kg. Plan a dedicated spot, a level floor and, for any move, two people or a suitable trolley. Do not try to carry it alone up a staircase.

Safety rules
At 4000 W, cables, extension leads and power strips must be sized for the current drawn. Leave generous clearance around the vents, do not stack anything on the station and keep it away from water, as its protection against moisture is not specified. Do not exceed the stated limits, and entrust any link to a fixed installation to a qualified electrician.
Care and storage
Dust the case with a dry cloth. Store the station in a dry, temperate room, away from flammable products, and follow the manufacturer’s manual for looking after the battery during long inactivity.
