As part of the EcoFlow early Prime Day Sale, the brand has launched another flash sale saving you up to $1,149 on four units. One of those units is the 3,072Wh DELTA 3 Ultra Portable Power Station down at $1,199 shipped, beating out Amazon by $500. While it carries a newer $1,599 MSRP since the brand made permanent price cuts earlier in the year, it’s still been seen climbing as high as $1,999 at Amazon, though it’s only gone as high as $1,699 since mid-September there. This deal matches the Prime Day pricing we saw in June, with the $400 markdown off the going rate landing it back at the second-lowest price we have tracked – $95 above the one-time and short-lived Lightning deal low from early March. Head below to check out the full lineup of deals while they last.
The DELTA 3 Ultra power station is a sizeable backup companion with a 3,072Wh LiFePO4 battery capacity, though it doesn’t offer the expandability like its DELTA 3 Ultra Plus counterpart (which can climb up to 11kWh). It has 10 output ports to cover connection needs (5x AC, 3x USB-C, 1x USB-A, and car port), providing steady power of up to 3,600W or surging higher up to 7,200W.
It brings along five primary recharging options. There’s the usual AC outlet recharging, which gives you the same input rate as connecting it to a gas generator. You can also use up to 800W of solar panel input to charge in the sunlight, or you have charge-as-you-drive options from either a vehicle auxiliary port or get faster speeds with the brand’s alternator charger.
