Our verdict
The first-generation C1000, replaced by the C1000 Gen 2, which recharges faster and puts out 2,000W. This one keeps the expansion-battery port Anker dropped for Gen 2, which is its only reason to exist now, and Anker's UK store showed it sold out on 21 September 2026. Buy it only if you find stock and want to add capacity later.
Good
- Expansion-battery port, dropped on Gen 2
- High solar input
- Fast recharge
Watch out
- Superseded by the C1000 Gen 2
- Sold out on Anker's UK store (checked 21 Sep 2026)
- App less mature than EcoFlow
