1 / 7EcoFlow DELTA 3 Portable Power Station, 1024Wh LiFePO4 (Renewed)
EF ECOFLOW: The EcoFlow DELTA 3 is a renewed, battery-powered portable power station listed with a 1024Wh LiFePO4 battery and 1800-watt output. Its stated capacity and fast-charging claims make it relevant for home backup and portable use, but the listing contains conflicting charge-time figures that should be clarified before purchase.
At a glance
- The title identifies this as a renewed DELTA 3, so its condition is distinct from a new unit.
- The listing claims 1800 watts of output and 120 volts, with residential use recommended.
- The manufacturer describes expansion up to 5kWh using specified EcoFlow battery packs.
- Manufacturer claims include 4000 cycles to 80% and a 10-year lifespan for daily use. These are claims, not verified outcomes.
