EcoFlow DELTA 3 Portable Power Station - 1024Wh Backup Battery for Home and Outdoors

Fast, reliable backup power when you need it most:

The EcoFlow DELTA 3 is a portable power station built around a 1024Wh LiFePO4 battery that charges from flat to full in just 56 minutes using X-Stream technology and a 1500W AC input. Whether you need a backup battery for the home during a power outage, reliable power for a campervan or motorhome, or a supply for cameras and laptops on location, the DELTA 3 keeps working kit running without delay.

More output than the wattage suggests:

The DELTA 3 delivers 1800W of AC output across four outlets, with a 3600W surge capacity for motor-start appliances. X-Boost extends this further, allowing the unit to run devices rated up to 2200W by intelligently managing power draw - so a travel kettle, small fan heater, or power tool that would otherwise exceed the station's rated output can still be used. Four AC outlets, two 100W USB-C ports, two 18W fast-charge USB-A ports, a car power outlet, and two DC5521 ports give you 13 output options in total.

Five ways to recharge, including solar:

The DELTA 3 accepts charge from five sources: AC mains (1500W, 56 minutes to full), solar panels (up to 500W via DC input, 130 minutes), 12V car socket, smart generator, or a combination of sources simultaneously. The EcoFlow App connects over Wi-Fi or Bluetooth, giving you real-time monitoring, time-of-use scheduling to reduce energy costs, and a Storm Warning Alert that automatically charges the unit to full when severe weather is forecast in your area.

Built to last a decade of regular use:

The DELTA 3 uses third-generation LiFePO4 cells rated to 4000 charge cycles before dropping below 80% capacity - the equivalent of roughly ten years of daily use. The integrated battery pack carries an IP65 rating for resistance against dust and water splashes. The built-in BMS monitors over 40 parameters covering current, voltage, temperature, and circuit risks, including thermal runaway propagation protection, to keep the unit operating within safe limits throughout its service life.

Expandable capacity up to 5 kWh:

If 1024Wh is not enough for extended outages or longer off-grid trips, the DELTA 3 is compatible with the DELTA 3 Extra Battery, DELTA Pro 3 Extra Battery, DELTA 2 Max Extra Battery, and DELTA 2 Extra Battery, scaling total capacity up to 5 kWh without replacing the main unit. The UPS function switches to battery power in under 10 milliseconds, making it suitable for protecting sensitive electronics and home office equipment during unexpected outages.

Setup and Care

Getting started:

Plug in the included AC charging cable and charge fully before first use. Download the EcoFlow App on iOS or Android and connect via Bluetooth for initial pairing, then switch to Wi-Fi for ongoing remote monitoring and scheduling.

Charging best practice:

For daily home standby use, the EcoFlow App's TOU (time-of-use) mode lets you schedule charging during off-peak electricity tariff hours. If using solar panels, ensure the panel output falls within the DC input range of 11V-60V and does not exceed 500W total.

Storage and transport:

Store the DELTA 3 at between 20°C and 30°C for best battery performance. When not in use for extended periods, EcoFlow recommend storing the unit at roughly 60% charge. The carry handle makes it straightforward to move between rooms or load into a vehicle at 12.5 kg.

Long-term care:

The BMS handles the majority of battery management automatically, including temperature monitoring and cell balancing. Keep the cooling vents clear of obstruction during operation and avoid exposing the unit to direct rain or sustained water exposure, even with the IP65-rated battery pack inside.
