The EcoFlow DELTA 3 Classic is a 1,024 Wh portable power station weighing 12.1 kg and measuring 39.8 × 20 × 28.3 cm. Its two Type F outlets deliver 1,800 W of pure sine output with peaks up to 3,600 W and an AC input of up to 1,400 W drives X-Stream fast charging that reaches 80% in 45 minutes and 100% in about 1 hour.
