Power for Every Need

The EcoFlow DELTA series scales from compact 1kWh units to expandable multi-kilowatt systems. Entry models run laptops, routers, lights and small kitchen appliances. Max and Ultra models add the capacity and output for refrigerators, power tools and air conditioners. Every model charges from a wall outlet, solar panels or a car socket, and you can monitor and control it from the EcoFlow app.

EcoFlow DELTA Pro Home Backup

For serious outage protection, the EcoFlow DELTA Pro home backup is the step up. The DELTA Pro delivers 3,600Wh of capacity and 3,600W of AC output, and extra batteries expand it to cover days of essential loads. Pair it with a transfer switch or Smart Home Panel to power selected home circuits automatically. Add solar panels and your backup system recharges itself without fuel.

Frequently Asked Questions

What is the difference between the DELTA series and the RIVER series?

RIVER units are small, lightweight stations for charging devices on the go. The DELTA series offers much higher capacity and output, enough to run household appliances and provide home backup.

Can the EcoFlow DELTA Pro power a whole house?

A single DELTA Pro runs essential circuits such as the fridge, lights, Wi-Fi, fans and medical devices. For heavier loads or ACs, step up to the DELTA Pro 3 or a DELTA Pro Ultra system with extra batteries.

How long will a DELTA power station run my appliances?

Multiply the battery capacity in watt-hours by 0.85, then divide by the appliance's wattage. For example, a 1,024Wh unit runs a 100W load for roughly 8 to 9 hours.

Can I charge an EcoFlow DELTA with solar panels?

Yes. Every DELTA model has a solar input. Charging time depends on panel wattage and sunlight, and larger models accept more solar power for faster charging.

Is it safe to use a DELTA power station indoors?

Yes. Unlike fuel generators, DELTA units produce no exhaust and run almost silently, so you can use them safely inside homes, apartments and offices.

How long does the battery last?

LFP-based DELTA models are rated for roughly 3,000 to 4,000 full cycles before capacity drops to 80%, which is around ten years of regular use.
