EcoFlow portable power stations are seeing some of the deepest Memorial Day discounts we’ve tracked, with savings of up to 57 percent. The brand’s models consistently rank among the best in our portable power station testing, and if you’ve been waiting for a price drop, this is it.
Not sure what to get? Reviews Editor Amber Joglar hauled the Delta 3 Plus to a five-day off-grid camping music festival, powering air pumps, fans, and power banks the entire time and coming home with over half the battery still remaining. Another one of our editors installed the Delta Pro Ultra X as a whole-home backup system and experienced two real outages. Both times, the system switched over so seamlessly that his internet never dropped. That kind of real-world performance is why EcoFlow models hold multiple spots in our portable power station roundup.
What sets EcoFlow apart from the pack is its speed and flexibility. The latest models feature some of the fastest wall charging in the category, LiFePO4 batteries rated for 3,000-plus charge cycles, and X-Boost technology that lets smaller units run appliances above their rated wattage. The Delta Pro 3—our pick for best whole-home backup—delivered 97 percent of its rated capacity in testing, and it’s currently 30 percent off. Here are the best EcoFlow deals available right now.
The Delta 3 Plus is our best overall pick among EcoFlow power stations, and it’s nearly 30 percent off. One editor brought it to a five-day off-grid camping music festival and came home with over half the 1,024-watt-hour battery still remaining. Its 1,800-watt output handles most appliances, and X-Boost pushes that above 2,200 watts for resistive loads like space heaters. EcoFlow says it charges to 80 percent from a wall outlet in just 40 minutes, and capacity is expandable up to 5 kWh with compatible battery packs. A 10-millisecond UPS switchover makes it a reliable backup for computers and networking gear.
The EcoFlow Trail 300 DC is an ultra-compact power station built for hikers and minimalist campers. Its 288-watt-hour LiFePO4 battery delivers 300 watts of DC output across five ports—two USB-C PD ports (up to 140 watts each), two USB-A ports, and a 12-volt car socket—so it can handle everything from laptops and phones to a 12-volt electric cooler. There are no AC outlets here, but at just 5.7 pounds, it’s 48 percent smaller and 27 percent lighter than EcoFlow’s already-compact River 3.
The River 3 is great for everyday portable power. At 7.8 pounds with IP54 water resistance, it’s small enough to sit on a desk or slide into a closet, but it still delivers 300 watts of AC output or up to 600 watts with X-Boost for running higher-draw devices. EcoFlow says its X-GaNPower technology makes it more efficient than similarly sized competitors, squeezing more runtime from the 245-watt-hour LiFePO4 battery, especially with low-draw devices like a Wi-Fi router or CPAP.
EcoFlow’s Rapid Mag is a 10,000mAh MagSafe-compatible power bank with Qi 2.2 certification, the latest version of the Qi wireless charging standard. This bumps wireless speeds up to 25 watts (compared to 15 watts on the previous Qi2) and provides better magnetic alignment for more efficient power transfer. That means it can take a last-gen iPhone 16 from zero to 50 percent in about 30 minutes wirelessly. A built-in 36-watt USB-C cable lets you charge up to three devices simultaneously, and a foldable kickstand doubles as a hands-free phone stand. At 8.1 ounces, it’s easy to throw in a bag or slide into your pocket.
At 45 percent off the price listed on EcoFlow’s website, the River 2 Pro is a strong mid-range option for weekend camping and light home backup. EcoFlow claims the power station’s 768-watt-hour LiFePO4 battery charges from empty to full in about 70 minutes via a wall outlet, and X-Boost boosts the 800-watt output to 1,600 watts, so it can handle higher-draw appliances you wouldn’t expect from a unit this size. Four AC outlets and 11 total ports give you plenty of flexibility, and at 17.2 pounds with a built-in handle, it’s still easy to carry to a campsite or move between rooms.
The Delta 2 shares the same 1,024-watt-hour capacity and 1,800-watt output as the newer Delta 3 Plus but at a lower price point. What you give up is a few extras: the Delta 3 Plus charges faster (80 percent in 40 minutes vs. 50 minutes), accepts twice the solar input (1,000 watts vs. 500 watts), carries an IP65-rated battery, and includes a 10-millisecond UPS for instant backup switchover. But if you don’t need those features, the Delta 2 still delivers the same core capacity with 15 total outlets, expandable storage up to 3 kWh, and a LiFePO4 battery rated for 3,000-plus cycles.
The Delta Pro 3 is our pick for the best whole-home backup, and right now it’s sitting at 30 percent off. In our testing, it delivered 97 percent of its rated 4,096-watt-hour capacity—far better than most large power stations—and ran a space heater pulling 1,300 watts for nearly six hours. Its 4,000-watt output scales up to 6,000 watts with X-Boost and supports both 120V and 240V, so it can handle heavy loads like a 3-ton central AC or a water pump. Capacity expands to 48 kWh with extra batteries, and a second unit, paired in parallel, pushes the combined output to 12,000 watts. At 115 pounds, it’s not exactly portable, but built-in wheels and a handle make it manageable indoors.
