Secure your home's energy independence with the EcoFlow Delta Pro Portable Power Station, the ultimate solution for home backup and off-grid power. This powerhouse delivers an unparalleled 3,600 running watts (7,200 peak watts), capable of powering up to 15 appliances simultaneously, including high-wattage devices. Its revolutionary X-Boost technology expands output to 4,500-W, meeting your power needs without fumes or noise. This is more than just a power station; it's an expandable ecosystem. The base 3.6kWh capacity expands up to a massive 25kWh with extra batteries and smart generators, creating a comprehensive home battery system. Charging is incredibly versatile with five ways to power up: an EV station, solar panels, a standard wall outlet, a car outlet or the EcoFlow Smart Generator. Combine methods for ultra-fast charging up to 6,500-SW. Whether preparing for an outage or heading for adventure, the Delta Pro provides robust, reliable power you can count on.

Yes, the EcoFlow Delta Pro can be left unattended for a few weeks and monitored through the EcoFlow app, as long as it is set up properly. If the unit is plugged into AC power and running a small fan, it will operate in pass-through (bypass) mode. This means the fan will normally run from the grid, and the Delta Pro will stay charged. If AC power goes out, the unit will automatically switch to battery power and continue running the fan. The EcoFlow app allows you to remotely monitor battery level, input/output power, and system status. For best long-term battery health, we recommend setting a maximum charge limit (for example, 80–90%) rather than keeping the battery at 100% continuously. The unit should be placed in a cool, dry, and well-ventilated area, and the fan’s power draw should be within the Delta Pro’s output limits.
The EcoFlow DELTA Pro is not silent, but it is much quieter than a gasoline generator. It uses built-in cooling fans to manage heat. Under light to normal use, the noise level is similar to a quiet office or normal conversation. When operating at high loads or during fast charging, the fan noise can increase to around 60–70 dB or more, which is clearly audible but still suitable for indoor use.
Using a Delta Pro won’t stop a GFCI outlet from tripping, because GFCIs trip when they detect a ground fault, which can happen naturally with refrigerators. The safest solution is to use a non-GFCI outlet if allowed, or check the refrigerator and outlet for issues.
The Delta Pro can supply a 3,600W resistive load from its battery, but it cannot continuously power a full 3,600W load for 1 hour while pass-through charging from a standard 120V 5-15 outlet. A 5-15 outlet can only provide about 1,500–1,800W of input power, which is not enough to support a 3,600 W load at the same time. In this situation, the Delta Pro would still be discharging the battery.
The EcoFlow Delta Pro has a battery capacity of 3,600 watt-hours. If you are running a continuous load of 3,100 watts, the estimated runtime would be about 1.1 hours (approximately 1 hour and 10 minutes). Please note that actual runtime may vary slightly depending on efficiency and operating condition.
