EcoFlow Delta 3 Classic
is a modern and reliable portable energy solution that combines high performance, smart control and durable battery technology. It is designed for home backup power, field work and hiking, providing reliable power in any situation.
At the heart of the device is a 1024 Wh LiFePO4 (LFP) battery, which provides significantly longer life and higher safety compared to traditional lithium batteries. With up to 4,000 charge cycles (up to 80% capacity) and an estimated lifetime of up to 10 years, it is a long-term investment in a stable energy supply. The battery works in conjunction with a smart BMS system that protects the device from overcharging, overheating and other potential risks.

EcoFlow Delta 3 Classic provides 1800 W of continuous power output and up to 3600 W of peak power to power most home appliances and tools – from laptops and TVs to fridges and power tools. Thanks to X-Boost technology, it can even handle devices with power requirements of up to 2600 W without overloading, while maintaining a stable and clean sine wave output.
One of the biggest advantages of the EcoFlow Delta 3 Classic is its ultra-fast charging. X-Stream technology allows you to recharge the battery from 0-80% in just around 45 minutes and fully charge it in around an hour, which is remarkably fast for its class. In addition, the device supports multiple charging modes including mains power, solar panels (up to 500W input), car charging and generator, offering maximum flexibility in the city or in the wild.

UPS function of the device (automatic switchover within about 10 ms) ensures uninterrupted power supply to critical devices such as computers or servers, avoiding data loss and downtime during power cuts. At the same time, the device operates very quietly – the noise level remains at around 30 dB, making it suitable for indoor use .
Compact design and weight of around 12.1 kg make the EcoFlow Delta 3 Classic conveniently portable, while the robust construction and automotive-standard LFP elements ensure durability in the most demanding conditions. An integrated smart app allows you to monitor power consumption in real time, optimise charging and use features such as timed operating modes and Storm Guard, which automatically prepares the unit for potential power outages.
EcoFlow Delta 3 Classic is the ideal choice for the user who needs a quick, reliable and smart source of backup power – whether it’s a domestic emergency, working on site or living an active lifestyle in the great outdoors.
