EcoFlow has launched a third phase of its Prime Day Sale through July 18, giving folks an extended period to score its power stations and solar generator packages at some of the lowest prices of the year – complete with extra 5%, 7%, and 9% savings, free gear with select bundles, a free gift for members on purchases over $500, and more. Among the switched-up lineup of deals, we spotted the DELTA Pro Solar Generator bundle with a 400W panel and getting a free transfer switch at $2,089.05 shipped, after using the promo code EFPDAFF5 at checkout for an additional 5% off. This bundle would normally cost you $4,898 at full price, which we’ve seen taken down to $2,199 at Amazon (where it’s currently priced without the free transfer switch) and $2,099 from the brand’s direct sales. The deal here is coming in lower than ever, with the combined 57% markdown here cutting $2,809 off the tag and landing things at a new all-time low price. Head below for more on the sale’s special promotions and the other deals.

EcoFlow has switched up the promotions during this third phase of its Prime Day Sale, starting with sitewide extra 5% savings using the code EFPDAFF5 at checkout. From there, you can score an automatic 7% savings on orders between $3,500 and $5,000, as well as an extra 9% savings on orders over $5,000 – though there are some units that these 7%/9% savings can’t be used on (more on the main landing page here). Members, aside from having their usual benefits, will also have access to some select special discounts while also getting a free Power Hat with orders of $500 or more. Lastly, select bundles are continuing their $500 installation subsidy

One of EcoFlow’s most sizeable legacy units, the DELTA Pro power station starts with a 3,600Wh LiFePO4 capacity and can expand as high as 25kWh when adding expansion batteries and connecting multiple power stations. It puts out a steady stream of up to 3,600W of power, surging up to 7,200W, and boasts 14 port options to connect devices and appliances. There are all the remote smart controls you could want through its companion app, and the station has three primary ways to recharge: plugged into a wall outlet, as well as your car’s auxiliary port, or you can connect up to its max 1,600W solar input. The included transfer switch gives you sectional home backup support, letting the station cover up to six of your breaker circuits in emergencies.
***Note: the extra savings have not been factored into the prices below, so be sure to use the code EFPDAFF5 at checkout for any orders under $3,500 for the best deal, with larger orders automatically getting the bonus 7% and 9% savings added in your cart.
