Prime Day runs June 23 to 26, but EcoFlow launched its deals two weeks early (on June 8) and the Delta 2 1800W portable power station is part of that early push, currently sitting at $429, down from its $699 list price. That is a $270 cut and lands within a few dollars of the Delta 2’s all-time low on Amazon which makes this one of the stronger early Prime Day deals available right now.
1,800W output, 15 outlets, no fumes
The Delta 2 puts out 1,800 watts of AC power through 15 total outlets which covers the vast majority of household appliances short of central air conditioning or electric dryers. That means a full-size refrigerator, a coffee maker, a CPAP machine, a TV, and a laptop can all run simultaneously without tripping the unit. For power outages, that level of output is the difference between waiting out a storm uncomfortably and barely noticing the grid went down. For camping and RV use, it replaces a gas generator without the exhaust, the noise, or the fuel logistics.
The LiFePO4 battery chemistry is the spec that separates the Delta 2 from cheaper power stations using standard lithium-ion cells. LFP batteries are significantly more stable at high temperatures, less prone to thermal runaway, and rated for over 3,000 charge cycles before degrading to 80% capacity. At one full cycle per day, that is more than eight years of daily use. EcoFlow backs this with a five-year warranty, which is unusually long for consumer electronics and reflects how seriously the company stands behind the chemistry.
0 to 80% in 50 minutes, solar-ready
Recharge speed is where the Delta 2 pulls away from most competitors at this price. Plugged into a standard wall outlet, it goes from flat to 80% in 50 minutes and hits 100% in 80 minutes, which EcoFlow calls X-Stream charging. That matters during an outage when the grid comes back briefly, or before a camping trip where you forgot to charge the night before. For off-grid situations, the Delta 2 accepts up to 500W of solar panel input, which can top it up from a compatible panel array in a few hours of direct sun. Solar panels are sold separately, but the input port is standard and compatible with most major brands.
Capacity is expandable too. The base 1,024Wh unit can be paired with an EcoFlow Delta 2 Extra Battery to reach up to 3kWh total, which extends runtime considerably for multi-day outages or extended off-grid trips. The app gives full remote monitoring and control over charging settings and output ports.
At 27 pounds with two handles, the Delta 2 is genuinely portable in a way that whole-home backup systems are not. The 4.7-star average across over 5,000 reviews is one of the highest in its category, and the combination of LFP chemistry, fast recharge, and a five-year warranty at $429 makes this one of those early Prime Day deals where waiting for the official dates is unlikely to get you a better number.
