Which is better for home backup?

The Anker Solix F3000, because of its 20 ms UPS switchover and expansion to 12kWh, or 24kWh with two units. The EcoFlow matches capacity and output but does not publish a switchover time.

Which recharges faster?

The Anker, at about 1 hour 18 minutes on AC and about 1.5 hours on 2,400W of solar. EcoFlow does not list recharge times for the Delta 3 Ultra.

Is the EcoFlow worth the extra?

It is not extra at the low: $1,299.00 on November 1 versus $1,299.99 for the Anker on November 5. The EcoFlow costs less and rates higher, but the Anker publishes more specs.

Both use LFP cells at 3,072Wh. Anker rates its pack at 4,000 cycles; EcoFlow does not publish a cycle count for this model.

Can either run a 240V appliance?

The Anker can, by pairing two units or adding an expansion battery. The EcoFlow listing does not state 240V support.

Which is better for RV or camping use?

The Anker, because of its dual-voltage solar input and fast solar recharge. Both weigh in as large units at this capacity.

Anker Solix F3000 Portable Power Station vs EcoFlow Delta 3 Ultra

Both units hold 3,072Wh of LFP and output 3,600W, so the choice comes down to charging speed, expansion and price. The EcoFlow Delta 3 Ultra was $1,299.00 at its lowest on November 1, and the Anker Solix F3000 was $1,299.99 at its lowest on November 5, so they are within a dollar at the bottom. Buy the Anker for faster solar and AC recharge and a bigger expansion ceiling; buy the EcoFlow if you trust its higher rating and want the lower floor price.
