EcoFlow Delta 3 Ultra Deal Persists Past Prime Day: What the 3072Wh Power Station Offers

EcoFlow has extended its Prime Day promotions with a sale running until October 18, and among the discounted items is the Delta 3 Ultra portable power station. According to TechRadar, the unit is now priced at $1,349, down from its standard $1,599—a $250 discount. This isn't the lowest price seen; TechRadar notes it was available for $989 at Wellbots during Black Friday last year.

The Delta 3 Ultra is designed for home backup and large appliances. It packs a 3,072Wh LFP battery, which provides enough stored energy to keep essential equipment running during shorter outages. The continuous AC output is 3,600W, with a 7,200W surge rating to handle the brief startup demands of compatible appliances. EcoFlow's X-Boost technology can support certain appliances rated up to 4,600W by adjusting the supplied voltage.

Charging is notably fast: EcoFlow claims the battery can reach 80% in just 89 minutes using a suitable AC or generator charging setup. The batteries are rated for a ten-year lifespan. Other features include 10ms automatic switching for backup power, quiet operation, and smart app control. Home backup connectivity options are also available.

The source material suggests this unit is best for homeowners preparing for power outages, those needing backup for essential equipment, or anyone seeking a high-capacity portable power station. The 3,600W output makes it suitable for a wider range of appliances than smaller portable power stations. Conversely, if you only need to charge phones, tablets, or a laptop occasionally, a smaller and cheaper power station would be more appropriate.

TechRadar's article also mentions other EcoFlow products on sale, such as the Delta 2 (2048Wh, 2400W output, 4800W surge, 68-minute fast charging) and the Delta Pro Ultra Plus (expandable 3-11kWh capacity, 3600W output, 7200W surge, six charging methods, 48-minute fast charging). However, the focus is on the Delta 3 Ultra.

As with any power station, actual performance depends on the appliances used and the duration of outages. The 3,072Wh capacity may not suffice for prolonged outages if powering high-draw devices continuously. The fast charging claim requires a suitable AC or generator setup, which may not be available in all situations.

The deal is live on EcoFlow's site until October 18. For those in need of substantial backup power, the Delta 3 Ultra at $1,349 could be compelling, but it's worth comparing with previous lows and other models. TechRadar's review history indicates EcoFlow units have scored well in tests, but individual needs vary.
