Description

The EcoFlow DELTA 3 Portable Power Station is engineered to bridge the gap between portability and serious power performance. With a 1 kWh (approx. 1024 Wh) battery capacity and a continuous AC output rating of 1800 W (surge up to 3600 W via X-Boost), this unit is designed to handle a wide variety of devices—from home appliances during an outage, to electronics and gear on the go.
It uses a long-life LiFePO₄ battery chemistry, capable of thousands of charge cycles, making it ideal for repeated use. The unit supports ultra-fast recharging via multiple input methods (AC, solar, car, generator), so you can restore its capacity in under an hour in many cases. Built-in smart features allow remote monitoring and control via the EcoFlow app, and the design supports expandability (up to several kilowatt-hours) to adapt as your power-needs grow.
Whether used for emergency home backup, outdoor adventures, RVing or mobile work setups, the DELTA 3 balances convenience and capability—giving you robust power in a manageable size.
