7x Faster AC charging - X-Stream tech means that DELTA 2 charges 7 times faster than the competition. That's 0–80% in just 50 minutes and 0-100% in 80 minutes with AC input.
Control from anywhere - Use the EcoFlow app to control your DELTA 2 from anywhere using Wi-Fi. Link with Bluetooth when off-grid. Either way, you can check charging data, customize settings and adjust the charging speed with ease.
Built to last 6x longer - Get 10 years of daily use until hitting 80% of its original capacity. That's down to its LFP battery chemistry giving you 3000+ cycles.
Smart Generator: Connecting DELTA Pro/DELTA Max/DELTA 2 to Smart Generator to charge up during extended blackouts.
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 2, DELTA Pro or DELTA Max.
Power 99% of your home devices.
A 1800W AC output means you can power more than 90% of your home appliances. That's your microwave, fridge, or even coffee maker covered in a blackout. Or, try plugging in up to 15 devices at once for when you're around the table with the family. Unlike other brands, DELTA 2 can prevent overloading from devices up to 2400W thanks to X-Boost technology.
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 2, 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 2 or DELTA Max and Smart Generator with the EcoFlow app. Dive into the settings to customize your power use or control DELTA Max remotely.
