When disasters strike, such as extended blackouts and severe storms, everyone needs a last-standing power supply to stay safe. The EcoFlow Smart Generator serves as an emergency option that integrates with your DELTA Pro or DELTA Max.
All the AC output you’ll need.
A single DELTA Pro unit packs a 3600W AC output, which can be expanded up to 4500W with X-Boost technology. Power 99.99% heavy-duty devices at home, outdoors, or at work. You can even pair two units together to achieve 7200W with Smart Home Panel.
The world’s fastest charging portable power station.
MultiCharge delivers record-breaking speeds at 6500W. To reach 6500W, you can opt for these charging methods.
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.
Multiple ways to control & monitor.
Control DELTA Pro either on the unit itself, using the remote control accessory, or unlock a ton of customization via the EcoFlow app. On the app, you can access your power settings, such as charging and discharging levels, AC charge speeds, control the Smart Generator and a whole lot more.

Please use the AC Charging Cable included in the package for fast charging. Do not use other cables to charge. Plug directly into an AC wall outlet and make sure that the wall output current is more than 15A. Otherwise, reduce the unit charging speed with the AC Charge Speed Switch. EcoFlow takes no responsibilities for any consequences caused by failures to follow instructions, including but not limited to charging with other AC charging cables.
