38% off/From $259

As part of its ongoing August Home Backup Sale running through August 17, EcoFlow has launched the next of its 48-hour flash sales that are taking up to 38% off four offers – two power stations, the WAVE 3 AC/Heater, and an add-on accessory charger. Among the offers, we’re seeing the best price yet on the DELTA 3 1500 Portable Power Station for $699 shipped, beating out its Amazon pricing by $100. Normally going for $1,099 at full price directly from the brand and $999 on average at Amazon, we’ve seen discounts take the costs down as low as $729 in March and April, with the time since only seeing falls to $799. Now, through August 8, you can take advantage of the 36% markdown here to score $400 off its MSRP at the best new rate that we have tracked. Head below for more on this unit and the other flash offers.

The EcoFlow DELTA 3 1500 power station comes as a larger capacity option among the DELTA 3 series, with a 1,536Wh LiFePO4 battery that can be expanded as high as 5.5kWh when adding on either the DELTA 3, DELTA Pro 3, or DELTA 2 Max expansion batteries. There are 15 ports to connect devices and appliances, with the station delivering 1,800W of steady output that can bump up to 2,200W of continuous power with its X-Boost mode activated via the remote controls on its companion app, surging even higher to 3,600W for hungrier needs. There are three primary ways to recharge its battery: via your car’s auxiliary port in 12.1 hours, through a standard outlet in 90 minutes, or with a max 500W solar input in 3.5 hours of sunlight.
