About this product

The EcoFlow DELTA Pro 3 is a UL9540-certified portable power station built around a 4,000Wh EV-grade lithium iron phosphate (LFP) battery, rated for 4,000 charge cycles while retaining at least 80% of its original capacity. It delivers a continuous 4,000W of pure sine wave AC power at both 120V and 240V, including during pass-through charging, and its X-Boost technology can handle surge loads up to 6,000W, making it capable of running a 3-ton central air conditioner alongside other essential appliances. Capacity is expandable from 4kWh up to 48kWh for extended outages lasting days to a week. AC recharging tops out at 1,800W, solar input accepts up to 2,600W, and the unit reaches 80% charge in roughly 50 minutes. The UPS function switches over in under 10 milliseconds. Additional outputs include a 100W USB-C Power Delivery port and 12V DC, while operating noise sits at just 30 dB. Weighing 51.5 kg and fitted with wide wheels and an ergonomic handle, it suits home backup, RV, and off-grid use. A 5-year warranty is included.

What people are saying

Reviewers consistently praise the EcoFlow DELTA Pro 3 for its massive 4kWh LFP battery, impressive 4,000W output, and the rare ability to deliver both 120V and 240V from a single unit, making it a standout for home backup, RV use, and off-grid applications. Its fast charging (0 to 80% in roughly 50 minutes via AC), broad expandability up to 48kWh, extensive port selection, quiet operation, and intuitive app control are frequently highlighted strengths. The most common criticisms center on its weight (around 114 lbs), which makes true portability impractical, and a pass-through AC power limitation that can cause the unit to shut off under high surge loads when plugged into the grid. Some users also note occasional software glitches requiring a BMS reset, fan noise under heavy loads, and a high price point that may not suit buyers with modest power needs.
