Anker Solix C1000 Review
The Solix C1000 is the 1kWh-class station for people who hate waiting: 0–80% wall charging in 43 minutes — the fastest we've researched — plus 1,800W of continuous output, a sub-20ms UPS switchover, and a footprint 15% smaller than comparable 1kWh units. Sale prices near $499 make it a genuine rival to the EcoFlow DELTA 2 on value. Its compromises are real too: a 600W solar ceiling that's modest for its class, and an expansion path that tops out lower than EcoFlow's.

Runtime estimates
Using our standard formula (1,056 Wh × 0.85 efficiency ≈ 898 Wh usable):
| Device | Estimated runtime |
|---|---|
| Full-size fridge (~60W average, cycling) | ~14–16 hours |
| CPAP, no humidifier, DC mode (~40W) | ~22 hours (~2–3 nights) |
| CPAP with humidifier (~90W) | ~10 hours (about 1 night) |
| Laptop 65W (recharges) | ~13 full charges |
| WiFi router + modem (~12W) | ~3 days |
| Box fan, medium (~60W) | ~15 hours |
| Microwave, 1,000W | ~54 minutes cumulative |
What the C1000 does best
- Fastest recharge in its class. 43 minutes to 80% beats the DELTA 2's 50 minutes and the Jackery 1000 v2's ~1 hour. When a storm gives you a short warning — or the grid flickers back on briefly — recharge speed is a real-world advantage, not a spec-sheet flex.
- True sub-20ms UPS. Unlike EcoFlow's EPS (<30 ms), Anker specs this as a UPS with under-20ms switchover — quick enough that a desktop PC or router typically won't reboot. If you work from home, that's the single most important line on this spec sheet.
- SurgePad handles motors. 2,400W surge is enough for the startup spike of a full-size fridge compressor or a sump pump — the appliances where cheap inverters trip.
- Compact for the class. Anker claims 15% smaller than comparable 1kWh units. At 28.4 lbs it's not light, but it fits in a closet corner or apartment balcony setup where bulk matters.
Honest limitations
- Solar ceiling is modest. 600W max solar input is fine for topping up but low against the DELTA 2's class-leading flexibility. If your plan is extended off-grid living on solar alone, rivals recharge meaningfully faster from panels.
- Expansion tops out at 2,112Wh. One add-on battery, and that's it. The DELTA 2 reaches 3,040Wh. If you might scale to multi-day whole-home backup later, the ceiling matters.
- 28.4 lbs is real weight. Slightly heavier than the DELTA 2 (27 lbs) and notably heavier than the Jackery 1000 v2 (23.8 lbs). Fine for garage-to-kitchen duty; annoying on stairs.
- The expansion battery is pricey. Doubling capacity costs several hundred dollars on its own — price the full path before treating "expandable later" as a plan.
- A Gen 2 exists. Anker has released a C1000 Gen 2 (1,024Wh, 2,000W output, ~49-minute full recharge). The Gen 1 reviewed here is the widely discounted unit and the better value when on sale — just know the newer model exists before you pay full price.
How it compares: C1000 vs EcoFlow DELTA 2
These two are priced within spitting distance and both deliver 1,800W continuous. Short version: the C1000 charges faster (43 vs 50 minutes to 80%), switches faster in UPS mode (<20 vs <30 ms), and handles motor surges better; the DELTA 2 usually wins on sale price (we've seen $349), expands further (3,040Wh vs 2,112Wh), and has a stronger solar ceiling. If you work from home and want the box that keeps your PC alive through flickers, C1000. If you want maximum watts-per-dollar, DELTA 2. Full DELTA 2 breakdown: EcoFlow DELTA 2 review.
Verdict
The Solix C1000 is the best 1kWh-class pick for work-from-home backup: fastest wall charging, a genuine sub-20ms UPS, and surge handling that covers fridge compressors — all in a compact box that regularly drops to ~$499. Its solar ceiling and lower expansion cap keep it from being the universal default, but for apartment and home-office outages, it's the station we'd plug our own routers into.
