EcoFlow DELTA 3 Ultra Plus Series Portable Power Station (3072Wh)
The EcoFlow DELTA 3 Ultra is built for flexibility and performance, giving users complete control over their power management. Through the EcoFlow app, you can use Smart Output Priority to decide which circuits stay powered, helping you extend runtime and conserve energy for your most essential devices. Its 3–11kWh expandable capacity means you can scale your power supply as needed, pairing it with an EcoFlow Smart Generator for automatic start-and-stop backup power during extended outages. With six charging options and ultra-fast performance, it can reach 0–80% in just 48 minutes using dual solar and generator input, ensuring you’re always ready for any situation.
Designed for demanding environments, the DELTA 3 Ultra offers a 3600W continuous output and a 7200W surge capacity, easily powering high-consumption appliances such as dryers, lawnmowers, and electric frying pans through X-Boost™ technology. Its automotive-grade full-tab LFP cells provide up to 10 years of reliable use, safeguarded by a 24/7 BMS and an EV-grade CTC structure that protects against condensation and bumps during transport. The system integrates seamlessly into your home with two connection options—Manual Transfer Switch and Inlet Box—and includes a rapid 10ms auto-switch to keep sensitive devices like NAS servers or computers running smoothly. Despite its power, it maintains whisper-quiet operation at just 25dB at 600W, and with the OASIS 3.0 Smart App, users can monitor energy use, activate Storm Guard Mode before extreme weather, and save on electricity through Self-Powered and Scheduled Task modes for daily efficiency.
