About this item

Product details

The EF EcoFlow Portable Power Station DELTA 3 Classical 1000 in dark offers a robust 1800W continuous output, expandable to 2600W with X-Boost technology, making it capable of powering high-demand appliances like refrigerators, microwaves, and power tools with grid-level stability. It features rapid X-Stream AC charging, allowing it to reach 80% charge in just 45 minutes, and supports fast solar recharging in 2.5 hours with an optional 500W solar panel. With a less than 10ms Uninterruptible Power Supply feature, it automatically switches to battery power to protect sensitive electronics from interruptions. This power station also includes smart app control for remote management and is built with durable LiFePO4 battery cells designed for over 10 years of daily use, ensuring reliable operation for camping, RVs, and home backup needs.
  • 2600W Output with X-Boost Technology:Power most household appliances and personal devices with 1800W continuous AC output and 3600W surge capacity. Activate X-Boost mode to expand output up to 2600W, so you can run heavier loads like refrigerators, microwaves, power tools and more without tripping protection. A 100W USB-C port also delivers high-speed charging for laptops, tablets and smartphones without extra adapters.

With a switchover time of less than 10 milliseconds, this power station automatically transitions to battery backup power for PCs, home servers, medical devices and other critical equipment, preventing data loss, work downtime, and unexpected interruptions.
  • Long-Lasting LiFePO4 Battery with EV-Grade Build:Engineered for years of reliable use, the DELTA 3 Classic uses premium LiFePO4 battery cells rated for 10+ years of daily use — far longer than traditional lithium-ion or lead-acid power stations. Its EV-grade Cell-to-Chassis (CTC) design and integrated smart Battery Management System (BMS) deliver enhanced safety, optimal performance, and long-term battery health in all conditions.
  • Fast Solar Recharging Capability:Harness clean, renewable energy to stay fully powered off-grid. When paired with an optional 500W solar panel, the DELTA 3 Classic fully recharges in as little as 2.5 hours. It’s the perfect sustainable solution for remote camping, van life, and long-term off-grid living wherever the sun shines.

Great price on Delta 3 with solar panels!

found this at a really great price! I've been wanting the Delta 3 with a solar panel. I priced this for weeks on Amazon and left the tab open. When I sought to purchase this set, it had gone up suddenly from 800.00 to nearly $1200. I believe it was the "interest shown" that caused the price spike. Checked here and Walmart had it at the right price, so I bought it here! I may never have to use it, but it sure is good to know that If there's a blackout in my area, I'll have both the delta and this delta 3 for backup. Thanks Walmart!

Good investment in peace of mind.

Our power outages are local and seldom more than a couple of hours. I have one protecting my frig and one for my sump pump. Each should hold up for 2 days. Any longer %26 I can quickly recharge from my electric car.
