Product Overview:

Take your power preparedness to the next level with the EcoFlow DELTA 2 Max, a high-capacity, ultra-reliable portable power station designed to support your home, outdoor activities, or professional needs. Featuring a massive 2048Wh LiFePO₄ battery and 2400W AC output, this powerhouse ensures that even the most demanding appliances—from refrigerators to power tools—run smoothly during outages or off-grid use.

The DELTA 2 Max is engineered with LiFePO₄ (LFP) battery technology, giving it a cycle life of over 3000 full charges, equating to roughly 10 years of daily use. With this extended battery longevity, it offers not just reliability, but a long-term investment in clean energy. It’s also equipped with advanced Battery Management System (BMS) protections, ensuring safety across temperature, voltage, and current fluctuations.

Recharging the DELTA 2 Max is incredibly efficient thanks to EcoFlow’s dual charging system. AC input reaches up to 2300W, bringing the battery from 0 to 80% in just under 60 minutes and 100% in about 1.1 hours. It also supports up to 1000W of solar input, allowing full solar recharging in 2.3 hours in ideal conditions—making it a perfect choice for sustainable and off-grid living.

When it comes to device compatibility, the DELTA 2 Max is built for serious multitasking. It features 15 output ports, including 4 AC outlets, dual 100W USB-C ports, USB-A fast-charge, DC5521 ports, and a 12V carport—capable of powering everything from laptops and smartphones to CPAP machines and household appliances. Its X-Boost mode allows operation of devices up to 3400W, widening the range of supported equipment.

Designed with both portability and performance in mind, the DELTA 2 Max weighs about 23kg, with rugged side handles and a compact design relative to its massive capacity. Whether you’re heading out in an RV, managing a job site, or ensuring uninterrupted home backup power, it offers a seamless blend of mobility and function.

The device also supports Wi-Fi and Bluetooth connectivity, letting you monitor usage, manage outputs, and update firmware via the EcoFlow app. With expandable capacity up to 6144Wh using additional EcoFlow Smart Batteries, and a 5-year warranty, the DELTA 2 Max sets a new standard in powerful, portable energy storage.
