EcoFlow DELTA 3 Classic Portable Power Station (1024Wh)

Overview

The EcoFlow DELTA 3 Classic Portable Power Station (1024Wh) is premium portable power without the premium price, giving you 1kWh of dependable backup that's ready in as little as 45 minutes. Whether it's a last-minute camping trip or an unexpected blackout, X-Stream fast charging takes the DELTA 3 Classic from 0 to 80% in 45 minutes and fully charges in 60 minutes on AC power, intelligently adjusting voltage and power for safe, high-speed recharging without compromising battery life.

It delivers a steady 1800W pure sine wave output with grid-level stability, enough to handle high-demand appliances like microwaves and power tools, and 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.

Long-Life LiFePO4 Battery Cells

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.

Three Ways to Recharge

Recharge three ways to suit wherever you are:

• AC charging: 0 to 80% in 45 minutes, full charge in 60 minutes
• Solar charging: up to 500W, 0 to 100% in approximately 2.5 hours

Whisper-Quiet, Compact and Portable

At 30dB or less, the DELTA 3 Classic runs barely above a whisper, comfortable inside a tent, a caravan or beside your desk. It's also compact and lightweight at around 12.1kg with a built-in handle, easier to store in tight spaces and lighter to carry, while delivering the same 1800W of output power as the larger DELTA 3 Plus, focused on what matters most.
