EcoFlow has not only launched a new RV Season Sale that will be running through Memorial Day and through the rest of the month with up to 61% discounts, but also a 24-hour flash sale with four offers. Two such offers give you deals on the brand’s portable AC/heater alongside the Smart Generator 4000, while two provide power solutions, starting with EcoFlow’s DELTA 3 Max Portable Power Station with a 500W alternator charger at $949 shipped, beating out Amazon by $50. This newer bundle may be seen here carrying an $1,848 MSRP tag, but we’ve more consistently seen it down around $999 over at Amazon throughout the year, with periods even dropped down to $949, which is only beaten by the one-time $848 low from Black Friday. Now, you can pick it up at its second-lowest tracked price (and the best rate of 2026) with $50 off its 2026 going rate and $899 off the full direct tag. Head below to check out the DELTA 3 Ultra solar bundle, and the other deals while they last.
This particular DELTA 3 Max power station bundle is a solid option for folks who plan to spend extended times on the road, as it upgrades the standard (and slow) car port charging speeds to much better 500W alternator charging speeds as you drive. It brings along a starting 2,048Wh LiFePO4 battery that can scale upwards to 10,240Wh by using extra batteries designed for either the DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2 stations. It can handle much of your appliances and essential devices with a steady 2,400W output (surging as high as 4,800W) through its nine connection port options (4x AC, 3x USB-C, 1x USB-A, and 1x car port).
As I mentioned, this bundle upgrades your charging-on-the-go efficiency with the alternator charger, while also providing you with three other means to top off the batteries while out on adventures: you can charge from an AC outlet to 80% capacity in around 68 minutes, which is also the rate a gas generator will provide, too. Lastly, you can connect up to 500W of solar panel input to refill the entire battery in around 3.43 hours with ideal sunlight the entire time.
