Anker SOLIX C1000 Review: Serious Challenger to EcoFlow Delta 2?

Short answer: The Anker SOLIX C1000 (1,056 Wh, ~$999) is a strong mid-range competitor with UPS capability and solid build quality. It matches the EcoFlow Delta 2 on capacity and price but loses on recharge speed and solar input. Choose it if you prefer Anker’s ecosystem or find it at a better price. Choose EcoFlow Delta 2 if faster recharge matters.

Where the SOLIX C1000 Wins

Faster UPS: At ~20ms switchover vs EcoFlow’s 30ms, the SOLIX C1000 switches slightly faster — though both are imperceptible to most equipment.

Higher solar input: 600W vs 500W maximum solar input. For cabin and off-grid use with large solar arrays, this matters.

Anker ecosystem: If you already use Anker products, the SOLIX app integrates with other Anker devices. Solid build quality consistent with Anker’s reputation.

Where EcoFlow Delta 2 Wins

Weight: 12 kg vs 27.2 kg is a massive difference. The Delta 2 is genuinely portable for camping and overlanding. The SOLIX C1000 at 27 kg is a stationary unit.

Recharge speed: 0.8h vs 1.4h — EcoFlow recharges nearly twice as fast on AC.

Price: $699 vs $999 — a $300 difference for similar capacity is significant.

Honest Verdict

The SOLIX C1000 is a solid product that loses primarily on weight and price vs the EcoFlow Delta 2. If Anker runs a sale bringing it to $699-750, the solar input advantage and slightly faster UPS make it competitive. At $999 vs $699 for similar capacity, the EcoFlow Delta 2 is the more rational choice for most buyers.

The SOLIX C1000 makes more sense for stationary home backup use where weight doesn’t matter and you have a large solar array benefiting from the 600W input.
