EcoFlow DELTA 2 + DELTA 2 Smart Extra Battery

Make it a triple. Expand capacity.

With a capacity of 1kWh to start with, you’ve got enough energy for your essentials for hours on end. Need even more? Add on the DELTA 2 extra battery to reach 2048Wh, or add on the DELTA Max Extra Battery to hit 3040Wh. Great for home backup or everyday appliances.

Power pretty much anything.

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 2200W thanks to X-Boost technology.

The fastest charging on the market.

X-Stream tech means that DELTA 2 charges 7 times faster than the competition. That’s 0–80% in just 50 minutes with AC input, or 0-100% in 80 minutes.

Go green without sacrificing speed.

Pair with solar panels and charge in as fast as 3-6 hours with 1x400W, 2x220W portable solar panels. With its MPPT (Maximum Power Point Tracking) smart algorithm, DELTA 2 can actively detect the voltage and current in real-time to reach the maximum power point with >98% efficiency. That means a more efficient charge than other brands.

The EcoFlow DELTA 2 + Smart Extra Battery combo creates a portable, high-capacity power system perfect for home backup during power cuts, outdoor adventures, and off-grid electricity needs. The base DELTA 2 power station features a 1024 Wh LiFePO₄ battery — a long-lasting chemistry rated for over 3000 charge cycles — and provides a robust 1800 W continuous AC output with up to 2700 W surge capacity. Thanks to EcoFlow’s X-Boost technology, it can handle loads beyond 1800 W, supporting many household appliances such as refrigerators, microwaves, power tools, and electronics.

Adding the Smart Extra Battery effectively doubles total capacity to about 2048 Wh, enabling longer runtime for devices and systems without increasing size drastically. Both batteries charge and discharge in sync, giving you extended use without significantly increasing complexity.

A major advantage of this setup is fast charging: the DELTA 2 alone can recharge from 0–80 % in around 50 minutes via AC mains using EcoFlow’s X-Stream technology. The system also supports up to 500 W of solar input, allowing you to recharge from renewable energy in just a few hours depending on conditions.

You can monitor and control both units via the EcoFlow app over Wi-Fi or Bluetooth, view real-time battery status, and optimise charging strategies. The stackable, portable design keeps the combo manageable and flexible for mobile use or home emergency backup.
