[Rapid Recharge – 0 to 100% in Just 1.5 Hours]
Powered by a robust 1500W AC input, the EcoFlow DELTA 3 1500 fully recharges from empty to 100% in only 1.5 hours. Solar charging is equally efficient, completing in around 3.5 hours, while the 800W EcoFlow Alternator Charger restores capacity in just 2.1 hours. Additional charging options, including the EcoFlow Smart Generator and Hybrid AC + PV input, also deliver a full charge within 1.5 hours. Wherever you are—at home, on the road, or outdoors—you’ll have reliable power ready when you need it.

[X-Boost Mode – Power for 99% of Home Appliances]
With support for up to 2200W of continuous output in X-Boost mode, the DELTA 3 1500 is engineered to run nearly all household devices. Its versatile output ports allow you to power up to 15 devices at once—from microwaves and refrigerators during outages to heavy-duty tools at a job site. This portable solar generator ensures your essentials stay operational no matter the situation.

[Whisper-Quiet Operation with Seamless Backup]
Equipped with EcoFlow’s X-Quiet technology, the DELTA 3 1500 runs at just 35dB under 600W loads and only 45dB up to 1200W, making it one of the quietest portable power solutions available. In backup scenarios, it switches power with a transfer time of less than 15ms—fast enough to protect sensitive systems like servers, NAS storage, and point-of-sale terminals without interruption.

[Built for a Decade of Use]
Thanks to advanced LiFePO4 battery cells, the DELTA 3 1500 maintains at least 70% capacity after 3,000 full charge cycles—providing up to 10 years of daily performance. Reinforced with IP54-rated protection and a triple safety design (LFP technology, dust- and water-resistant housing, and a smart Battery Management System), it delivers long-lasting durability for both indoor and outdoor use.

[Expandable Capacity up to 5.5kWh]
Adapt your power supply to any situation with expandable battery options. The DELTA 3 1500 connects seamlessly with DELTA 3, DELTA Pro 3, or DELTA 2 Max expansion batteries, boosting total capacity to as much as 5.5kWh. From extended blackouts to multi-day camping trips, your power station scales with your energy needs.
