The EcoFlow DELTA 3 Classic Portable Power Station charges from 0–80% in just 45 minutes and fully charges in 60 minutes with AC charging, keeping you powered faster and smarter — whether indoors, outdoors, or on the move. X-Stream technology enables ultra-fast charging without compromising battery life, intelligently adjusting voltage and power to ensure safe, high-speed recharging.
It delivers a steady 1800W pure sine wave output with grid-level stability — enough to handle high-demand appliances like microwaves and power tools. With X-Boost mode, it supports devices up to 2400W without tripping or slowing down. When the grid drops, the DELTA 3 Classic switches to battery in under 10 milliseconds, fast enough to keep desktops, modems and other sensitive gear running without a flicker. At 30dB or less, it runs barely above a whisper — comfortable inside a tent, a caravan, or beside your desk.
The DELTA 3 Classic uses long-life LiFePO4 (LFP) cells built for up to 10 years of reliable power, with an intelligent Battery Management System that constantly monitors temperature, voltage and current to guard against overcharge, over-discharge, short circuits and overheating. Recharge three ways — AC, solar (up to 500W) or alternator — and monitor energy usage and control settings from the EcoFlow app over Wi-Fi or Bluetooth, including Storm Warning Mode to auto-top-up backup power before severe weather hits.
