EcoFlow Delta 3 Plus

EcoFlow DELTA 3 Plus: Keep household essentials powered at home or outdoors

A power cut can interrupt more than the lights: the EcoFlow DELTA 3 Plus stores 1,024 Wh of energy and is rated to run up to 99% of household appliances. It’s a portable power station for home backup and outdoor use, with enough capacity for a range of everyday equipment and an automatic UPS switch in under 10 ms for connected devices that need uninterrupted power. That quick changeover is useful for sensitive equipment during an outage. Away from a wall socket, its solar input accepts up to 1,000 W through an MPPT system; EcoFlow states a full solar recharge can take as little as 70 minutes, including in cloudy conditions. The compact unit measures 36 × 26 × 25 cm and weighs 12.5 kg, so it can be carried between storage and a work area or taken along for power outdoors. Its 1,800 W rated output, with a 2,700 W peak, covers a broad range of appliances. For quieter settings, it runs at 30 dB when the load is below 600 W. The honest detail to keep in mind is that the quiet figure applies to that lower-load range, not every use.

Power and Charging Features

• Fast AC recharge: EcoFlow’s X-Stream charging system accepts up to 1,500 W of AC input and can recharge the station fully in 56 minutes. That short recharge time is useful when you have a limited window to replenish it between periods of use.
• Solar input: The 1,000 W MPPT solar input supports off-grid recharging, with a stated full-charge time of up to 70 minutes. EcoFlow says it can still charge on cloudy days, a useful detail for outdoor use when sunshine isn’t consistent.
• Automatic UPS switching: The station switches to battery power in less than 10 ms during a power interruption. This fast transfer is relevant for sensitive connected equipment that needs its supply to continue through a brief outage.
• 1,800 W output: The rated output is 1,800 W, with a peak of 2,700 W. That distinction matters when planning for appliances with higher starting demands: the peak figure is not the same as the continuous rated output.
• LiFePO4 battery: Its lithium iron phosphate battery is rated for 4,000 cycles before reaching 80% capacity. That cycle rating gives a clear reference for expected battery life over repeated charging and use.
• Quieter at lighter loads: At loads below 600 W, the DELTA 3 Plus operates at 30 dB. That makes the stated noise level relevant for lower-power use in quieter indoor or outdoor settings.
• Multiple connections and inputs: There are 11 output ports, along with an 800 W car input for charging on the move. The housing is rated IP65 for water and dust protection, adding a defined level of protection for the station’s structure.
