The EcoFlow DELTA 3 Ultra Portable Power Station delivers powerful, reliable energy for RV setups, off-grid cabins, and home backup applications. With a 3072Wh capacity and 3600W AC output (7200W surge), it can easily power refrigerators, freezers, coffee makers, induction cooktops, and power tools—making it a versatile and capable solution for both mobile living and stationary backup.
Recharge from 0–80% in just 89 minutes using AC wall power or a generator, or go renewable with up to 800W of solar input for efficient off-grid charging. The DELTA 3 Ultra can also be integrated directly into your setup via Manual Transfer Switch or Inlet Box connections, supplying up to 30A of stable power for RV circuits or home essentials.
Built for durability and long-term performance, it features automotive-grade LiFePO₄ (LFP) cells protected by an advanced BMS system, plus an EV-grade CTC structure that safeguards against vibration and moisture. With Class B EMC certification, it meets residential safety and emission standards for worry-free use.
Operating at just 25dB (at 600W), the DELTA 3 Ultra runs whisper-quiet, even indoors. Through the EcoFlow OASIS 3.0 Smart App, users can track power usage, schedule charging, and enable Storm Guard Mode to automatically prepare for incoming weather events.
Note: The DELTA 3 Ultra is a standalone power station and does not support expandable battery modules. For expandable capacity and extended runtime, consider the DELTA 3 Ultra Plus or the DELTA 3 Pro, both available from Craze Outdoors.
At 32.7 kg, the DELTA 3 Ultra delivers a remarkable balance of portability and power—perfect for those who need a dependable, high-output energy solution for RV living, off-grid cabins, or whole-home backup readiness.
