Our verdict

The previous generation, kept here because it still does one thing the DELTA 3 does not: take an extra battery, up to 3kWh. Otherwise the DELTA 3 has the newer pack and the faster recharge, and EcoFlow's UK store showed the DELTA 2 sold out on 21 September 2026. Worth buying used or on clearance if expansion matters to you; not worth waiting for.

Good

  • Expandable to 3kWh, which the DELTA 3 is not
  • 1,800W runs most appliances
  • Fast charging

Watch out

  • Superseded by the DELTA 3
  • Sold out on EcoFlow's UK store (checked 21 Sep 2026)
  • Heavier than camping-only units
