With its official Memorial Day Sale having ended, EcoFlow is having its Monthly Madness promotions for members (free to sign up) that include up to 57% in initial discounts, as well as extra savings on orders over $3,000, and plenty of EcoCredit earning and reward options for even more savings (more on these below). Among the lineup, we’re seeing the biggest discount (as well as returning Black Friday pricing) on the DELTA 2 Solar Generator bundle with a 220W panel for $699 shipped, which also scores you 3x or 2x EcoCredits, depending on your member level. This package normally fetches $1,648 at full price, which we’ve been seeing come as low as $749 in 2025 sales until today. You’ll be getting $949 in savings here for today and tomorrow at the lowest price we have tracked, making it a great option to kick start your solar backup setup or expand with a more humble model for temporary trips away from home.
Let’s go over the special two-day promotions that we’re seeing during this event. First, the obvious reason these events are so great for opportunists – that purchases will score 2x EcoCredits for standard members, while Plus members earn 3x EcoCredits with their orders. For clarification, memberships are free, and you’ll gain the Plus status after accumulating at least 6,000 EcoCredits. Next, there’s the Lucky Spin wheel that you can trade EcoCredits to play twice a day for various rewards alongside the usual EcoCredit redemption options you’ll find at the bottom of the landing page. Lastly, members will be getting an automatically added extra 5% savings on any orders over $3,000.
EcoFlow’s DELTA 2 power station is a great choice for traveling companions from the brand’s many options, especially for weekend camping and road trips to keep essential devices and small appliances up and running – plus, the solar panel helps to ensure it can keep doing so should the journeys be extended. It starts with a personable 1,024Wh LiFePO4 capacity that can have two expansion batteries added to expand up to 3,072Wh. There are 15 versatile ports for plenty of connection options, with the unit delivering a steady 1,800W of power that can surge as high as 2,200W when needed.
The increased power output, as well as charging times, are increased from the brand’s X-Boost tech that is present here, giving you an 80% battery in just 50 minutes when plugged into a wall outlet, or you can wait a little longer at 80 minutes for a full battery. You’ll be able to take full advantage of the sun’s rays to recharge in nature with the included panel, while the station can go further, as it sports a max 500W input. There’s also the option to connect it to your car’s auxiliary port or utilize its max 1,100W of DC input. It’s rated for 3,000+ life cycles, giving you over eight years of everyday use, or it’s well suited to hold a charge for months on end in case of emergencies, which will see it last for a much longer timeframe.
***Note. The prices on individual models over $3,000 have had the extra 5% savings factored in below, with the discount being automatically applied in your cart, but don’t forget that savings can increase when buying multiple units together too.
