The EcoFlow DELTA 3 Classic is a modern portable power solution that combines high capacity, fast charging and reliable performance in a compact form factor. With a capacity of 1024 Wh, it can power a wide range of devices, from basic household appliances to power tools, while delivering a stable power output of 1800 W and up to 3600 W of starting power.

The device uses advanced LFP (LiFePO4) battery technology, which allows for a long lifetime of up to approximately 10 years and increased safety and stability of operation. An integrated Battery Management System (BMS) monitors real-time status, temperature and voltage to ensure optimal performance and overload protection.

One of the key benefits is the extremely fast charging using X-Stream technology, which allows charging from 0 to 80% in about 45 minutes and up to 100% in about one hour. In addition to conventional AC charging, it also supports solar charging up to 500 W, allowing complete independence from the mains and use in the wild or on the move.

DELTA 3 Classic also includes a UPS function with a response time of 10 ms, which means that in the event of a power failure, it automatically switches to battery power without interrupting the operation of devices such as computers, servers or network equipment.

Its quiet operation (approximately 30 dB at lower loads) makes it suitable for use indoors, in offices, caravans or camping. The compact and robust design makes it easy to carry, while ensuring resistance to a wide range of operating conditions.

Smart management via the EcoFlow app allows monitoring of consumption, battery status and optimisation of performance, including features such as automatic charging against bad weather (Storm Guard), further enhancing emergency preparedness.

EcoFlow DELTA 3 Classic is therefore a complete solution for anyone who needs a reliable, powerful and responsive power source at home or on the move.
