The EcoFlow DELTA 3 is a 1,024 Wh portable power station that weighs 12.5 kg, measures 39.8 × 20 × 28.4 cm and carries an IP65 rating on its housing. Its four Type F outlets deliver 1,800 W of pure sine output with peaks up to 3,600 W and X-Boost up to 2,400 W, enough to cover about 99% of household appliances. A 1,500 W X-Stream AC input recharges the battery in just 56 minutes, and UPS switchover in under 10 ms keeps fridges, NAS units or CPAP machines running through outages. Capacity can be scaled up to around 5,000 Wh by pairing it with extra batteries, and the LiFePO4 chemistry is rated for 4,000 cycles to 80% capacity.
