Our Take
The DELTA 3 Plus is EcoFlow's mid-size LiFePO4 power station, built for weekend campers, van lifers and anyone wanting home backup for essentials during a power cut. Sitting between compact power banks and whole-house systems, its 1024Wh capacity handles laptops, mini-fridges and power tools without the bulk or price tag of larger units, while remaining expandable if your needs grow.
Key Features
1024Wh LiFePO4 (LFP) battery chemistry, rated for a significantly longer cycle life than older NCM power stations
Continuous AC output of 1800W, with an X-Boost mode allowing higher-draw appliances to run at reduced efficiency
Rapid AC recharging, capable of going from empty to a high charge level in under an hour
Expandable capacity via EcoFlow's extra battery modules, for households wanting multi-kWh backup
Multiple simultaneous outputs: several AC sockets, USB-A and USB-C (including higher-wattage USB-C for laptops), and a car socket
Solar input support for off-grid charging, compatible with EcoFlow's portable panels
Our Verdict
A solid choice for anyone wanting dependable, quick-charging backup power for camping trips or home outages, without stepping up to a full home battery system. Skip it if you only need something pocketable for phone and camera charging, or if budget is tight, as cheaper LFP units exist with lower output.
