EcoFlow Delta 2 Review: The Best All-Around Power Station

If you could only buy one portable power station, the EcoFlow Delta 2 would be a strong contender. It’s not the cheapest, lightest, or highest-capacity option, but it strikes the best balance across every category — and that makes it the most versatile unit we’ve tested.

Key Specs at a Glance

• Capacity: 1,024Wh (expandable to 3kWh)
• Output: 1,500W (2,250W with X-Boost)
• Weight: 27 lbs
• Charge Time: ~80 minutes (wall outlet)
• Battery Type: LiFePO4 (3,000+ cycles)

Who Is It For?

Everyone. Seriously. The Delta 2 works for camping, emergency backup, RV trips, and even as a daily-use backup for your home office. The expandable capacity means it can grow with your needs.

X-Boost: The Secret Weapon

EcoFlow’s X-Boost technology lets the Delta 2 power devices rated up to 2,250W — well beyond its 1,500W rating. It works by intelligently managing voltage delivery, and in our testing, it successfully powered a 1,800W hair dryer, a 2,000W space heater (on low), and a portable induction cooktop.

This is a meaningful advantage over competitors like the Jackery 1000 v2, which is limited to its rated 1,500W.

Expandable to 3kWh

The Delta 2 accepts one EcoFlow DELTA 2 Extra Battery ($849), bringing total capacity from 1,024Wh to 2,048Wh. That doubles your run time without buying a whole new unit. It’s a smart investment if you think your power needs might grow.

Charging Speed

80 minutes from 0 to 100% on a wall outlet. That’s among the fastest in this price range. Solar charging is equally impressive — up to 500W input means a full charge in about 3 hours with compatible panels.

The downside: the fan gets noticeably loud during fast charging. If you’re charging it in a tent or bedroom, you’ll hear it.

The EcoFlow Ecosystem

The Delta 2 plugs into EcoFlow’s broader ecosystem: solar panels, smart home panels, and the EcoFlow app. The app provides real-time monitoring, firmware updates, and remote control. The Smart Home Panel integration ($699 extra) lets you wire the Delta 2 directly into your home’s electrical panel for seamless backup.

What Could Be Better

At 27 lbs, it’s a few pounds heavier than the Jackery 1000 v2 (22 lbs). The fan noise during fast charging is a legitimate annoyance. And at $849, it’s priced at the top of the 1kWh class.

The Bottom Line

The EcoFlow Delta 2 is the Swiss Army knife of power stations. X-Boost expands what it can power, expandable capacity future-proofs your investment, and fast charging means it’s always ready to go. If you want one unit that does everything well, this is it.
