Score EcoFlow’s DELTA Pro 3 4,096Wh LiFePO4 power station at $2,659 low (Reg. $3,699), more from $209

52% off/From $209

EcoFlow has switched up some of its lineup of power station deals in the second phase of its ongoing Spring-to-Summer Sale through May 18, keeping the WAVE 3 and GLACIER cooler discounts and extra sitewide savings active while changing some prices and switching out certain offers. Among the offers this go around, folks have another opportunity at the lowest price on the newer DELTA Pro 3 Portable Power Station for $2,659.05 shipped, after using the sitewide promo code EFRVSALEAFF at checkout for an additional 5% off. Outside of these sales you’d be pressed for $3,699 on this model at full price, which we’ve mostly seen brought down to $2,899 (not counting bonus savings) by discounts until the brand’s recent Mega Sale from last month, when it first fell to $2,799. Not only is that starting price returning, but so too are the extra savings, dropping things back to the lowest rate we have tracked while beating out Amazon.

One of EcoFlow’s newer power stations, the DELTA Pro 3 starts off with a 4,096Wh LiFePO4 capacity that you can further bolster upwards to as high as 48,000Wh. Likewise, its starting 4,000W of output power (which surges to 6,000W) will also expand with additional equipment up to 12,000W – particularly when three power stations have been connected together. Unlike the other units under the brand’s flag, this one boasts a massive array of recharging methods: seven solo-source options and 18 combination options. Plugging it into a standard wall outlet, for example, fills you back to an 80% battery in 50 minutes, or you could take advantage of the 2,600W max solar input, EV charging, cigarette outlets in cars, dual PV charging, and much more.

There are 14 output port options to cover all your devices and appliances, one of which happens to be a TT-30R port to cover RV needs too – with you able to monitor and adjust settings and performance through the smart controls via the companion app. It’s one of the few models that’s been given the brand’s X-Core 3.0 tech, providing superior host safety, performance, and intelligence improvement. It also allows for its surging power output to climb higher for more demanding appliances while also increasing charging speeds, lessening noise and temperatures, improving the battery management system, and extending its overall lifespan – you can charge and recharge it every day for nearly 11 years, which means with less use it’ll last you many more beyond.
