The EcoFlow DELTA 3 Max Portable Power Station Powers Your Entire Home With Expandable Capacity Over 12kWh
Whether you're gearing up for a cross-country RV adventure, fortifying your home against unexpected outages, or expanding your remote work capabilities, the EcoFlow DELTA 3 Max Portable Power Station delivers power and peace of mind that's ready whenever and wherever you need it.
Power on Demand With the EcoFlow DELTA 3 Max
When the grid goes down, your entire home can be at risk. Freezers thaw, lights go out, and every essential—from medical devices to communication tools—becomes useless. Outages can last hours or even days, and the longer they drag on, the harder it becomes to keep life running.
Relying on gas generators creates its own problems. They are loud, polluting, and unsafe to run inside. Fuel shortages during storms and disasters make them even less reliable when you need them most.
The EcoFlow DELTA 3 Max eliminates those risks with massive capacity, high output, and industry-leading speed. With 2,048Wh of capacity, the DELTA 3 Max delivers enough energy to power almost anything in your home. Its 2,400W AC output with a 3,600W surge handles refrigerators, washing machines, power tools, and more with ease.
Recharge to 80 percent in just over an hour with X-Stream technology, or pair with solar panels for a clean and renewable energy source that keeps you independent. Quiet, emission free, and safe for indoor or outdoor use, the DELTA 3 Max is a true whole-home backup solution that also fits seamlessly into RV and off-grid life.
With the DELTA 3 Max, you are not just buying a power station. You are buying uninterrupted security, comfort, and freedom.
