Which is better for running a fridge or space heater?

Both deliver 1,800W continuous, which covers a typical fridge or a 1,500W heater. The EcoFlow's 3,600W surge gives more headroom for compressor and motor startup.

The EcoFlow Delta 3 Plus is rated for 4,000 cycles to 80% capacity; the Anker SOLIX C1000 is rated for 3,000. Both use LiFePO4 chemistry.

Is the EcoFlow worth the extra $169?

At $719.00 versus $549.99 at Amazon as of November 6, 2026, yes if you need the higher surge, UPS switchover, IP65 battery or 5kWh expansion. If not, the Anker covers most loads for less.

Which charges faster from a wall outlet?

Nearly the same: 56 minutes for the EcoFlow at 1,500W input and 58 minutes for the Anker at 1,300W.

Can either run a CPAP or home network through an outage?

Both can, but the EcoFlow's sub-10ms UPS switchover is the safer choice for electronics that cannot tolerate a gap. The Anker does not publish a switchover time.

Which is easier to carry?

They are close: 27.5 lb for the EcoFlow and 28.44 lb for the Anker. Neither is a one-hand carry for most people.
