Delta Pro 3 battery - Ecoflow

EcoFlow DELTA Pro 3 - The ultimate energy source for autonomous vanlife

Do you live on the road? Are you fitting out a van for the long haul? The DELTA Pro 3 is more than just a battery: it's a complete power station, designed to give you long-lasting autonomy, power all your equipment and free you from the traditional electricity network, without compromising on comfort.

A capacity designed for real van life

With its 4096 Wh capacity, the DELTA Pro 3 can power a 12V fridge continuously for several days, or run a coffee maker, computer, microwave oven or even an induction hob. And if you have bigger needs (heating, audio mixing, professional use), you can add external batteries to reach up to 12 kWh.

Ultra-powerful, silent and connected

It delivers up to 4000 W continuously (8000 W peak): perfect for heavy users. And yet it's ultra-quiet (

Fast charging, even on the move

The DELTA Pro 3 recharges in record time: just 50 minutes to reach 80% from a mains socket. In van, it can be powered by a solar panel up to 2600 W, or connected to the alternator via the cigarette-lighter input or Anderson port. You drive, it recharges. Simple.

Built to last (really)

Its new-generation LiFePO₄ battery can withstand up to 4,000 cycles at 80%: the equivalent of 10 years of intensive use. It features an advanced BMS protection system (overheating, overvoltage, etc.), and can act as an intelligent UPS ( UPS mode) if you switch between mains and battery sources.

Ultra-complete connectivity

With its 7 AC sockets, USB-A/C ports, cigarette lighter socket and Anderson port, you can plug in all your mobile devices, whether at home or at work. Even simultaneously.
