You have 72 hours to save up to 57% on these four EcoFlow units, including the DELTA 3 Max power station at $749, more

As part of its continuing Home Backup Sale offers, EcoFlow has a 72-hour flash sale running that is seeing up to 57% discounts on two power station favorites and two add-on accessories (one of which fits the power stations). Many of these deals are returns from previous flash sales, like EcoFlow’s popular DELTA 3 Max Portable Power Station at $749 shipped, beating its Amazon pricing by $20. While you may see a $1,499 MSRP adorning this model’s tag, it has peaked a few times up to $1,199 or more at Amazon over the last several months, with today’s deal knocking an additional $50 off the most readily available sale prices. While the price has gone lower to $699, that was only during Black Friday and Cyber Monday sales, making this the next-best price at $450 off the going rate (and $750 off the MSRP). Head below to check out the full lineup of flash deals while they last through February 21.

Coming as a bolstered descendant of the DELTA 3 Classic (which is also part of these flash offers), EcoFlow’s DELTA 3 Max power station brings along double the capacity with a 2,048Wh LiFePO4 battery. That capacity also boasts more versatile scaling than we usually see from power stations, with it able to reach a max 10,240Wh capacity with any extra batteries from the DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2 models.

It’s a highly capable mid-tier option that provides up to 2,400W of steady output power through its nine ports (4x AC, 3x USB-C, 1x USB-A, and 1x car port), with a surging potential as high as 4,800W. As one of the brand’s newer backup power solutions, it has added gas generator connections alongside the standard AC charging, up to 500W solar charging input, or car auxiliary charging – the latter being much faster with an alternator charger instead.
