Battle Mid-range
Anker SOLIX C1000 Gen 2 vs EcoFlow Delta 3 vs Bluetti AC70
The three best mid-range portable power stations go head-to-head. Anker Gen 2 brings 43-minute charging and sub-10ms UPS, EcoFlow delivers 1,800W output with the best solar input, and Bluetti offers the best value at $499–$599.
In the mid-range class (700Wh–1,100Wh), these three stations represent the best you can buy in 2026. Anker C1000 Gen 2 leads on charge speed and UPS quality, EcoFlow Delta 3 leads on output and solar input, and Bluetti AC70 leads on value.
All three use LiFePO₄ (LFP) chemistry and offer UPS modes. The Anker C1000 Gen 2's sub-10ms UPS makes it the only mid-range station that's genuinely medical grade — relevant if you're backing up a CPAP or router. UPS guide →

⚠️ C1000 Gen 2 is not expandable. The original C1000 supported expansion batteries — the Gen 2 does not. If you might need more than 1,056Wh in the future, step up to the C2000 Gen 2 instead. Anker brand review →
