EcoFlow DELTA 2
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.

Big enough to run most household appliances (including a kettle) but still merchandised as 'portable' by EcoFlow. A strong middle ground if the smaller DELTA 3 isn't enough but a fixed home-backup unit is overkill.
