EcoFlow DELTA 2

EcoFlow DELTA 2 portable power station delivers 1800W AC output, stepped up to 2200W with X-Boost technology, from a 1024Wh battery that expands to 2048Wh or 3040Wh with additional battery packs. Built for home backup as well as off-grid use, the DELTA 2 range keeps essential appliances running during a power cut and covers everything from small electronics to larger household devices. It suits homeowners planning for outages, families wanting backup security and anyone who needs serious power away from the mains. With expandable capacity and multiple charging methods, you can scale the setup to match your household or trip.

Key Features of EcoFlow DELTA 2 Portable Power Station

The DELTA 2 range is built around high output, expandable storage and charging speed, giving you a power station that can grow with your needs. Depending on how you configure it, capacity and charging times will vary slightly across the range. The features below cover what matters most when choosing between DELTA 2 setups.

Expandable Battery Capacity

The DELTA 2 starts at 1024Wh, with the option to add an extra battery to reach 2048Wh, or a DELTA Max Extra Battery to reach 3040Wh. This expandable design means you are not locked into a fixed capacity from day one, so you can add storage later if your power needs grow. It suits households planning ahead for longer outages or bigger appliance loads, without needing to buy a completely different unit.

High AC Output with X-Boost Technology

With 1800W of continuous AC output, the DELTA 2 covers the majority of household appliances straight out of the box. X-Boost technology allows the unit to briefly handle devices rated up to 2200W, reducing the risk of overloading with higher wattage equipment. This makes the DELTA 2 a practical option for running kettles, microwaves or power tools alongside smaller everyday electronics.

Fast AC and Solar Charging

Using X-Stream fast charging technology, the DELTA 2 can reach 80% charge in around 50 minutes from a standard AC socket, with a full charge following in around 80 minutes. Solar charging is also supported, taking in up to 500W from compatible EcoFlow solar panels and recharging fully in roughly 3 to 6 hours depending on sunlight. Having both options means you are not tied to one charging method, whether you are at home or off-grid.

App Control and Monitoring

The DELTA 2 connects to the EcoFlow app over Wi-Fi or Bluetooth, letting you check charging status and battery level without needing to read the unit's display directly. From the app, you can also adjust charging speed and monitor how the power station is performing while it is in use. This remote visibility is useful for anyone using the DELTA 2 as a home backup, where checking in without walking over to the unit saves time.

Battery Life and Portability

Built around LFP battery chemistry, the DELTA 2 is rated for over 3000 charge cycles, giving a working life stretching towards 10 years with regular use. At around 12kg, it remains lighter than many comparable power stations of similar capacity, making it manageable to move between rooms or load into a vehicle. This balance of long battery life and manageable weight suits both permanent home backup setups and occasional trips away.
