EcoFlow Delta Pro 3

EcoFlow DELTA Pro 3 | High-capacity power for home backup

LFP battery chemistry is the defining choice in the EcoFlow DELTA Pro 3: it supports a long cycle life, with 4,000 cycles before capacity reaches 80%. Its 4,096Wh capacity makes this a substantial home power station for households that need more than a small backup battery. The 4,000W output can run demanding appliances, including central air conditioning or a water pump, and supply kitchen appliances and a garage door opener at the same time, within the available power. That combination makes it useful during an outage, or wherever mains power isn’t available. It’s also made for straightforward placement: take it out of the box, connect it and use it without altering the house. EcoFlow’s X-Quiet technology keeps operating noise low, which matters if the unit is near a living space or bedroom overnight. Charging is another strong point. X-Stream technology takes the battery from empty to 80% in 50 minutes, while combining charging methods can raise the charging input to 7,000W. At 51.5kg, it’s a substantial unit rather than something to casually carry from room to room; its appeal is dependable household-scale power in one unit.

What it does

• High-output AC power: Seven AC outlets provide up to 4,000W in total, with an 8,000W peak. X-Boost supports devices rated up to 6,000W, useful for appliances with higher power demands.
• Solar charging: Solar input reaches 2,600W across two ports: a high-voltage input up to 1,600W and a low-voltage input up to 1,000W. That gives you two solar charging paths with different voltage ranges.
• Power for smaller devices: Two USB-C ports deliver up to 100W each, and two USB-A ports provide up to 18W each. A 12V DC output supplies up to 378W in total, with separate DC5521 and Anderson connections.
• Smart Home Panel 2 support: Connect up to three DELTA Pro 3 units to EcoFlow’s Smart Home Panel 2. During an outage, the panel switches over in 20ms and can manage up to 12 circuits through the app.
• IP65-rated battery: The battery is rated for protection against dust and water, and the supplier also describes resistance to shock and fire. This rating adds reassurance when the unit is used beyond a spotless indoor setting.
• Long cycle life: EcoFlow specifies 4,000 cycles until the battery retains 80% of its capacity. The stated estimate is 11 years of daily use, depending on conditions.
• Wireless and wired connections: Wi-Fi, Bluetooth and CAN are available for connecting and managing the power station. These options support app-based control and system connections.

Good to know

Alongside AC and solar charging, the DELTA Pro 3 accepts power from a vehicle: the listed input is up to 8A at 12V or 20A at 48V. AC charging input varies by supply, with a stated maximum of 1,800W at 120V and 3,600W at 240V. The AC input range is 100–240V, at 50/60Hz. These figures are useful when comparing charging options for a home or travel setup.
