The EcoFlow DELTA 3 Ultra stores 3072Wh in LFP (LiFePO4) cells and delivers 3600W of 120V AC (7200W surge), with X-Boost for resistive loads up to 4600W. A 30A outlet, sub-10 ms UPS switchover and up to 800W of solar input make it a strong choice for home backup, RV power and job sites.
Overview
DELTA 3 Ultra is EcoFlow’s 3 kWh member of the DELTA 3 family. It pairs a 3072Wh LFP battery with a 3600W, 120V inverter and a 30A outlet, so it can run larger household and RV loads that smaller power stations cannot. When grid power drops, it switches to battery in under 10 ms, which keeps computers, networking gear and fridges running.
Key points
- 3600W output, 7200W surge. X-Boost mode runs heating-type appliances rated up to 4600W at reduced power.
- Charging: AC wall input (100-120V, 15A) and up to 800W of solar input. EcoFlow quotes 0-80% in about 89 minutes from the wall or a generator.
- LFP chemistry with EMC Class B rating and app control over Wi-Fi and Bluetooth.
- Warranty: 5 years (3-year standard plus 2 years extended on EcoFlow app registration).
Applications
Home backup for essential circuits and appliances, RV and van power, off-grid cabins, tailgating and contractor tool power.
