It’s the final day of EcoFlow’s early Prime Day Sale, and the brand’s final flash sale is in full swing through the rest of the day. The flash savings here are taking up to 54% off three units – two power station bundles and a bundle for the brand’s newest AC/heater solution. Leading the sale is the DELTA Pro Portable Power Station that comes with a free transfer switch for $1,709.05 shipped, after using the code EFPDAFF5 at checkout for an additional 5% savings – plus, you’ll also be getting a free RAPID 5,000mAh power bank thrown in too. We’ve been seeing many different flash sales focusing on the DELTA Pro at this same rate during this sale, which usually carries a $3,699 MSRP, though it is regularly sitting around $1,999 from Amazon (currently $1,784 there). Not only are you getting another chance at the biggest savings and the best price here, but you’re doing so while also getting the means for sectional home backup support.

One of the best and most expansive of EcoFlow’s legacy models, the DELTA Pro power station is ready to cover your campsites, outdoor gatherings, and home backup emergencies with a 3,600Wh LiFePO4 capacity that you can expand as high as 25kWh with future investments. There are 14 port options here, through which the station provides up to a steady 3,600W output that can surge up to 7,200W to cover larger appliances. It comes with three primary means to recharge: plugged into a standard outlet, through your car’s auxiliary port, or by connecting up to a maximum 1,600W solar input. The included transfer switch gives you sectional backup support of up to six circuits in your home or on an RV, with it pre-wired for easier installation.

You can also pick up the brand’s DELTA 3 Portable Power Station with a free protective bag at $529 shipped, down from its usual $778 pricing. This is a smaller and more affordable backup option that has a 1,024Wh LiFePo4 capacity and can be expanded up to 5,120Wh with various expansion batteries from across the DELTA ecosystem. It provides 1,800W output, surging to 2,200W when needed, and has 13 total output ports to use for connections to devices and appliances. It also boasts an expanded list of recharging options, including through an AC outlet, with a max 500W solar input, through car charging, generator charging, or there’s the multi-charging option of AC and solar together.
The last of these offers gives you the latest WAVE 3 Portable AC and Heater with an add-on battery and a free bag at $899 shipped, coming down from $1,299. With the battery included here, you can get up to 8 hours of wireless cooling/heating in your tent, car, or anywhere else you’re settling down. The 1,800W output here can “drop temperatures by 15 degrees in 15 minutes,” while the 2,000W heating output hits similar speeds, “raising the temperature by 17 degrees in 15 minutes” – with it able to cover 120 to 180 square feet spaces. There’s even some cool smart control expansions here, including the PetCare mode that automatically starts cooling once temperatures reach 77 degrees, among others.
