Power 99% of your home devices.
With EcoFlow's X-Boost technology, DELTA Max can power heavy-duty devices up to 3000W. That means during a power outage or blackout, you can continue to power your fridge, dryer, and more. That's the industry gold standard for a portable power station of this size and capacity.
Built for any emergency.
Compared to a traditional gas generator, the EcoFlow Smart Generator offers better fuel efficiency and less energy loss when you charge DELTA Pro or DELTA Max. It achieves this by directly charging your portable power station through a simple and efficient DC charging process.
Charge and power devices at the same time.
In emergencies, sometimes things don’t go to plan. Not only does the EcoFlow Smart Generator give you last-standing emergency power, it also features an AC output to power other devices while recharging your unit with an extra battery.
Control, monitor, and manage your energy use.
Control and monitor your DELTA Max and Smart Generator with the EcoFlow app. Dive into the settings to customize your power use or control DELTA Max remotely.
