EcoFlow has become the one-stop portable power station specialist with solutions for any and every conceivable need. You can take a Delta 2 on recreational camping trips that is still efficient but affordable, or go all out with a Delta Pro 3 that will keep your entire house running during winter outages. The company understands that backup power is not one-size-fits-all, and their product line reflects that thinking.
In celebration of Prime Day, nearly their entire range has hit all-time low prices, including this flagship Delta Pro 3 that’s dropped $1,200 from its usual $3,699 price point to $2,499 (32% off). This is the kind of investment that pays for itself the first time a storm knocks out power for days and you’re the only home on the block with lights, heat and a working refrigerator.
Delta Pro 3 features a 4096Wh LFP battery capacity that translates to real-world power that can keep a full-size refrigerator for approximately 40 hours, a window AC for about 12 hours or charge your laptop more than 50 times. These automotive-grade LFP cells coupled with IP65-rated CTC battery pack technology protect against water and dust intrusion and extend the life of the unit as a whole. We’re looking at thousands of charge cycles before you notice any noticeable drop-off in capacity.
Scalable Power That Grows With Your Needs
Where this system truly reveals its brilliance is in the scalability: That 4096Wh base capacity can be increased all the way to a staggering 48kWh with the addition of additional batteries or by connecting EcoFlow smart generators so you can begin with the base model and add on down the road as budget allows or as you determine you require the added capacity. With that degree of expansion potential, you’re looking at two to four days of entire house backup power in case of an extended outage. The Delta Pro 3 accepts both 120V and 240V voltage and features a 4000W output up to 6000W with X-Boost technology activated and up to 12000W when multiple units are running in parallel.
Charging flexibility is what sets this unit apart from all others. It has seven unique ways to recharge and 18 combinations, including AC wall outlets, solar panels, gas generators, EV charging piles, and the EcoFlow Smart Home Panel 2. Thanks to its solar charging capability, you can completely ignore fuel concerns in extended off-grid situations.
The plug-and-play capability has you literally unpacking it, plugging in your devices, and you’re up and running. The portable handle design makes this 110-pound unit manageable to move around your property or load into an RV. The EcoFlow app gives you complete control and monitoring capability from your smartphone even when you’re away from home. You can check battery levels, adjust output settings and monitor power consumption in real-time.
X-Quiet technology keeps operational noise at 30 dB that is quieter than a whisper and on par with the ambient noise of a library. You can run this unit beside your bed all night without noise disturbance which is vital during multi-day outages when you need around-the-clock power for CPAP machines or other medical devices.
The 10-millisecond switchover time protects delicate electronics during power transitions. Your servers, NAS devices, and entertainment systems experience essentially zero downtime when the switch is made to battery backup from grid power.
EcoFlow backs the Delta Pro 3 with a five-year warranty and attentive customer service. At $2,499, this is serious value for a system that can act as a substitute for a traditional backup generator.
