62% off/From $389

As part of its continuing Early Prime Day Sale event, EcoFlow has launched another 48-hour window for up to 62% savings on a collection of units, which are mostly focused on smart extra batteries and add-on batteries. The only unit with a power station included is the DELTA 2 Portable Power Station with a smart extra battery for $679 shipped (automatic discount in cart), which Amazon surprisingly doesn’t have bundled, but you can find the station and the battery separately for $99 more. While it may have a $1,798 tag attached, you can more often find these two units starting for around $1,298, with discounts having seen things go as low as $799 previously. Now, for two days, you can grab the pair with a larger-than-ever $619 markdown off the going rate ($1,119 off the MSRP) for the best price we have tracked. Head below to check out the rest of this flash sale lineup.

It may be one of EcoFlow’s legacy solutions, but the DELTA 2 power station remains a popular companion for folks, especially with it starting here at an expanded 2,048Wh middle-of-the-pack LiFePO4 capacity, which can further scale up to 3,072Wh with a third battery. Through its 15 output ports (6x ACs, 4x USB-As, 2x USB-Cs, 2x DCs, and 1 car port) this station provides up to 1,800W of steady power with the ability to surge as high as 2,200W.

Plugging the station into an AC outlet allows it to get back to an 80% battery in around 50 minutes (not counting any expanded setup) and full in around 80 minutes. You’ll also have the options to recharge from up to 500W of solar panel input, from a gas generator via the DC port, or from your vehicle’s auxiliary port as you drive.

***Note: some of the units below are cut down to their flash sale prices within your cart, so don’t be caught off guard by the higher starting rates on some listing pages.
