As part of its ongoing Mother’s Day Sale, which will continue for another week, EcoFlow has launched a 48-hour flash sale with up to 56% discounts on four units – two power station offers and two add-on accessory offers. Among the two power solutions, things start with the DELTA 2 Max Portable Power Station with an extra battery at $1,469 shipped, beating out its Amazon pricing by $30. While you may see it holding a $3,298 MSRP direct from the brand, it’s only gone as high as $2,799 over the past year, and 2026 hasn’t seen it climb any higher than $1,699. While we have seen the price fall lower in the past, you’re still looking at a solid $230 markdown off the recent 2026 going rate, and $1,330 off the highest price of the last year. Head below to learn more about this bolstered setup and browse the other flash offers. You can also check out the full EcoFlow Mother’s Day Sale with up to 64% discounts in our original coverage here for the next week.
EcoFlow’s DELTA 2 Max power station is coming with double the bolstered power, thanks to this flash sale bundle, which gives you a starting 4,096Wh LiFePO4 capacity (over the base 2,048Wh) that can have one more extra battery added on to reach a max 6,144Wh capacity. There are 15 output ports (6x ACs, 4x USB-As, 2x USB-Cs, 2x DCs, and a car port) for a handy array of versatile connection options, through which it can provide devices and appliances up to 2,400W of steady power and surge up to a 3,400W maximum.
Like many of its sibling power stations, this model has four primary recharging options. There’s the usual AC charging that you’d expect, as well as the solar charging functionality with up to a maximum 1,000W input. From there, you can also plug into your car’s auxiliary port (the cigarette lighter port) to charge as you drive, or use both AC and solar charging simultaneously for faster speeds.
