AC Charging
Plug into any wall socket and DELTA 3 Classic hits 80% in just 45 minutes, or a full charge in 60. Whether it's a sudden power cut or a last-minute trip away, you're powered up before the bags are.
Activate EcoFlow's exclusive Storm Guard Mode[3] to auto-start charging when extreme weather alerts hit—so you're always prepared, even when away.
Solar Charging
Pair it with EcoFlow solar panels for up to 500W of free, silent energy - a full charge in around 2.5 hours of good sun. Made for off-grid weekends at the bach or campsite.
Alternator Charging
On the road, add an EcoFlow 500W Alternator Charger[4] to top up from your vehicle as you drive - 0-100% in about 2.5 hours. Power that keeps up with the journey.
Run the things that matter.
1800W output (3600W surge), with EcoFlow X-Boost up to 2400W.
EcoFlow DELTA 3 Classic (1024Wh) delivers a steady 1800W pure sine wave output with grid-level stability—enough to handle high-demand appliances like microwaves and power tools [5]. With X-Boost™ mode, it supports devices up to 2400W without tripping or slowing down—giving you seamless power for the moments that matter.
Less than 10ms backup, automatically.
When the grid drops, DELTA 3 Classic switches to battery in under 10 milliseconds - fast enough to keep desktops, modems and other sensitive gear running without a flicker. Set it up as an everyday UPS and you may never notice the next outage.
Quiet enough to forget it's on.
At 30dB or less, the Classic runs barely above a whisper. Inside a tent, a caravan or beside your desk, it won't disrupt sleep or focus.
