Outdoor Life 950 Wh · 90%
At light loads it delivers much less
At about 34 W, Outdoor Life measured 650 Wh, 62% of rated. The unit's own running costs take a bigger share when the load is small. Bear this in mind for a CPAP, a fridge overnight or a few lights.

Questions
How much usable power does the Anker SOLIX C1000 have?
About 950 Wh. Outdoor Life measured 950 Wh at about 380 W, 90% of the rated 1,056 Wh. On a small 34 W load it gave 650 Wh (62%), which we keep apart because a station's own power use weighs heavily on small loads.
Is the Anker SOLIX C1000X the same as the C1000?
They share the model number (A1761), the manual and the 1,056 Wh battery. Anker's US store now sells it under the C1000X name, and we found no Anker statement of any difference.
What's the difference between the C1000 and the C1000 Gen 2?
The original has six AC outlets to the Gen 2's five and takes one BP1000 expansion battery; the Gen 2 isn't expandable. The Gen 2 is lighter (24.9 lb against 28.4 lb), puts out 2,000 W rather than 1,800 W, and charges faster: 49 minutes against 58, both in UltraFast mode.

Where this data comes from
Capacity figures come from the independent testers linked above. We record their numbers, the date and the load, and link to their reports; the testing is theirs. Specs come from Anker SOLIX's own US documents, and we note where they disagree with each other or with test results. Prices are checked by hand on the brand's US store.
