EcoFlow DELTA 2

1,024 Wh LFP unit with EcoFlow's X-Stream tech that hits 80% from a wall outlet in 50 minutes — the fastest recharge in the 1 kWh class. 1,800W AC continuous, 100W USB-C PD, 15 outlets, and an expansion path to 3 kWh. At $429 (39% off the $699 MSRP) it's also one of the most validated buys on Amazon, with 4,800+ reviews at 4.7 stars.

  • 1,024 Wh LFP cells, 3,000+ cycles to 80% — 6× the cycle life of NMC competitors at the same price
  • 1,800W AC continuous output (X-Boost mode pushes resistive loads further)
  • X-Stream wall recharge: 0–80% in 50 minutes, 0–100% in 80 minutes
  • 100W USB-C PD output charges a MacBook Pro at full speed without a separate brick
  • 500W solar input via XT-60 connector
  • Expandable to 3 kWh with DELTA 2 / DELTA Max extra batteries
  • 15 outlets total, 5-year manufacturer warranty

The good and the bad

✓ Pros
  • X-Stream wall recharge in 50 minutes — fastest 1 kWh class on the market
  • 27 lb is class-leading for a 1 kWh LFP unit — 10 lb lighter than the Bluetti AC180
  • 4,800+ reviews at 4.7 stars and Amazon 'Overall Pick' badge — the most validated unit in this tier
  • 100W USB-C PD on the chassis itself runs a 16-inch MacBook Pro at peak charge speed
  • Modular expansion to 3 kWh keeps the buy future-proof
✕ Cons
  • $429 is the deal price; base list is $699 — expect creep back as the promotion rolls off
  • 1,024 Wh fills the camping role but won't run a fridge for 24 hours straight
  • App requires an EcoFlow account; a subset of buyers report sync issues on iOS
  • Mixed long-term storage reports — a minority of users see charge drift if left below 30% for months
Who this is for

If this is you, you're in the right place

  • Most-validated buyer (4,800+ reviews counts for something)

    Amazon "Overall Pick" badge with 4.7-star average. Five years on the market with the longest reliability track record in this size.

  • Camping or weekend power needs under 1.5 kWh

    27 lb is class-leading. 50-min recharge to 80% means it's topped off between drives. 100W USB-C PD covers a 16-inch MacBook Pro at full speed.

Who should skip this

If this is you, keep shopping

  • Anyone needing 24-hour fridge runtime

    1,024 Wh runs a fridge ~6-7 hours. Step up to the DELTA 2 Max or AC200L for full-day coverage.

  • NMC-skeptic at all costs

    EcoFlow uses LFP here, but the X-Boost protocol on resistive loads is software-driven — voltage sags briefly under sustained 1,800W+ draws.

Real-world runtime

How long it lasts on real loads

Estimates apply 85% inverter efficiency to the rated capacity. Real-world numbers vary with temperature, battery age, and appliance duty cycle.

FAQ

How long does the EcoFlow DELTA 2 run a typical refrigerator?
A modern A++ fridge averages ~150 W. With 1024 Wh of usable battery, that's roughly 7 hours of continuous runtime before it depletes.
Is the EcoFlow EcoFlow DELTA 2 worth it versus competitors?
EcoFlow competes directly with EcoFlow, Bluetti and Anker in this segment. The Lab Score of 8.9 suggests a solid unit at this price point. Cross-shop on /compare with your second pick.
Is it LFP or NMC?
The EcoFlow DELTA 2 uses LFP cells. LiFePO₄ delivers more cycles but weighs more.
