Up until now, 2kWh models struggled to deliver more than 2kW of AC current (220V), but the manufacturer has aimed to introduce a new, highly powerful yet more compact pack than its premium models.
EcoFlow DELTA 3 Max: A 2kWh Battery Delivering 3000W AC
Sometimes, a powerful battery is essential for using tools or household appliances while maintaining a portable form-factor.
The DELTA 3 Max (2,048 Wh) thus provides an AC output of 2,400 W (4,800 W peak) in a lighter format, making it the ideal solution for powering portable devices.
Paired with the DELTA 3 Max Plus (2,048 Wh), it is the first 2kWh portable power station in the industry with a 3,000 W AC output (6,000 W peak). Equipped with X-Boost 3.0 technology, the device can be used both indoors and outdoors thanks to its powerful and portable format.
The two packs feature:
• a customizable discharge strategy: set a battery threshold (for example, SOC at 50%) to automatically shut off non-essential devices when capacity falls below this level in order to extend the autonomy of priority devices.
• Intelligent overload protection: If the total load exceeds the maximum limit (3,000 W), the system first cuts off non-essential circuits to ensure uninterrupted and safe operation of essential equipment.
Faster Recharge
The DELTA 3 Max Plus (2,048 Wh) offers five charging methods and can recharge from 0 to 80% in 47 minutes when plugged into a wall outlet, while the Max model only takes 51 minutes. Users can also recharge their device using the following modes:

• Alternator charging (1,000 W): from 0 to 80% in 95 minutes, which is ten times faster than with traditional methods
• Hybrid generator charging: 0% to 80% in 47 minutes with AC input + generator
• Dual solar and alternator charging: from 0 to 80% in just 51 minutes, even off-grid
The energy autonomy of the Plus model is expandable and can be increased from 2 kWh to 10 kWh by adding additional compatible EcoFlow smart batteries. This allows for sufficient capacity to power essential home circuits for several days, or to power demanding off-grid setups.
Built to Last
Both DELTA 3 Max models are equipped with an LFP battery, X‑Guard 3.0 safety architecture, and advanced BMS protection that extend the device’s lifespan up to 10 years. The devices are also covered by a warranty for up to 5 years (standard 3-year warranty + 2-year warranty extension if the device is registered on the EcoFlow app).
The automotive-grade CTC (cell-to-chassis) structure ensures performance stability, anywhere and anytime. Designed to withstand extreme environments, the DELTA 3 Max Plus (2,048 Wh) can charge equipment at temperatures up to 32°F, discharge down to 14°F, and be stored between 14°F and 113°F. The X-Quiet 3.0 cooling technology ensures its operation at less than 30 dB: the device remains silent whether in your living room or in your yard.
The Plus model is also the only 2kWh portable power station in the industry with a 10 ms UPS and HID protocol that instantly protect sensitive electronic devices such as NAS servers from outages, twice as fast as the industry average of 20 ms.
