Anker SOLIX C1000X: 1,056 Wh, Expandable

Anker SOLIX C1000X: 1,056 Wh LiFePO4, 1,800 W continuous, expandable. Why its 2,400 W peak figure is disputed and what it can start.

Which version: C1000X is the listing ankersolix.com now serves for the original C1000 (/products/c1000 redirects here; its spec table is headed 'C1000 Portable Power Station'); not the C1000 Gen 2 (1,024Wh, 2,000W).

The C1000X is what ankersolix.com now serves for the original C1000: the old C1000 address redirects here and the spec table is headed "C1000 Portable Power Station". Unlike the newer C1000 Gen 2 (1,024 Wh, 2,000 W continuous, no expansion), the C1000X takes an expansion battery that brings it to 2,112 Wh. It also weighs more: 28.44 lb against the Gen 2's 24.9 lb.

Continuous, peak — and a peak figure in doubt

Anker rates continuous AC output at 1,800 W. The peak is less clear. The spec table labels 2,400 W as "AC Surge Output", but the feature list says "Run 2,400W Loads With SurgePad" — SurgePad is Anker's mode for resistive loads such as heaters, not a motor-start rating — and the C1000 Gen 2 page credits the C1000 with 3,000 W peak. Loads well under the lower figure are safe to plan around: the top-freezer refrigerator and the 5,000 BTU window AC both need 1,200 W to start. The 1/2 HP sump pump needs 2,150 W to start, close enough to 2,400 W that we would not count on it. The circular saw's 3,600 W start is out of reach either way.

Runtime with the refrigerator's 47 W yearly average: 1,056 Wh × 0.85 ÷ 47 W ≈ 19.1 hours, using the 0.85 factor explained on the methodology page.

The LiFePO4 battery is rated for 3,000 cycles to 80 %+ capacity. Makers set that end-of-life threshold differently — Jackery counts to 70 %, EcoFlow to 80 % (how makers define cycle life).

What is missing

The UPS switch-over row on the maker's page is blank, so this card prints it as not published. Wall charging is quick: 0–100 % in 58 minutes at up to 1,300 W.

Add your appliances to the calculator to check your own load against the C1000X.

Frequently asked questions

Is the C1000X the same as the C1000 Gen 2?

No. The C1000X has 1,056 Wh, 1,800 W continuous output and an expansion port; the C1000 Gen 2 has 1,024 Wh, 2,000 W continuous and no expansion.

What is the real peak output: 2,400 W or 3,000 W?

Anker's pages disagree. The C1000X spec table says 2,400 W surge, the feature list ties 2,400 W to SurgePad, and the C1000 Gen 2 page gives the C1000 3,000 W peak. Plan motor starts against the lower figure.

Can it run a refrigerator?

Yes on the numbers: the top-freezer refrigerator needs 360 W running and 1,200 W to start. At its 47 W yearly-average draw, 1,056 Wh × 0.85 ÷ 47 W gives about 19.1 hours.

Does it work as a UPS?

Anker's page leaves the UPS switch-over time blank, so we cannot give one. If switch-over speed matters for your equipment, ask Anker before you rely on it.

What warranty does it have?

Anker lists a 5-year warranty.
