1024Wh of Powerful, Fast-Charging Home and Outdoor Backup — Ready in 45 Minutes
The EcoFlow DELTA 3 Classic is a 1024Wh portable power station built around automotive-grade full-tab LFP cells and engineered to deliver 1800W of pure sine wave AC output with X-Boost support up to 2600W. Whether you're running a microwave during a power outage, powering a home office, or heading off-grid, the DELTA 3 Classic charges from 0 to 80% in just 45 minutes via AC — and supports up to 500W of solar input for clean, renewable backup. A 10ms UPS switchover keeps critical devices like NAS systems and servers online without interruption, while whisper-quiet operation under 30 dB and zero emissions make it suitable for any indoor or outdoor setting. Available as a standalone unit or bundled with the EcoFlow 220W Portable Solar Panel.
⚠ Sold Separately. The EcoFlow Smart Generator 3000 (Dual Fuel) and EcoFlow 500W Alternator Charger are accessories sold separately and are not included with this unit unless specifically selected as part of a bundle option.
