Anker SOLIX C1000: what it runs in an outage

The SOLIX C1000 balances the 1kWh-class trade-offs well — strong output, fast charging, decent solar and an expansion path — but two different products share its name.

Good fit if you…

  • want a 1kWh station that recharges fast from the wall or solar (600W)
  • want the option to double the battery later (2,112Wh with the BP1000)
  • want a quick UPS switchover (under 20 ms) for a router or modem

Look elsewhere if you…

  • are buying the C1000 Gen 2 — this page’s numbers don’t apply to it
  • need the C1000 Gen 2 thinking it expands — it doesn’t; only Gen 1 takes the BP1000

Estimated runtimes

These come from the same calculation as the planner: our representative appliance figures, efficiency estimated from the load, and a 10% battery reserve. The range runs from our cautious to our optimistic estimate; verdicts use the expected value in between. Your appliances will differ — try your own.

Estimated runtime for common outage loads

Wi-Fi, lights and phones, 8 hoursabout 11–14 hCovers it
Fridge alone, 12 hoursabout 10–13 hOnly just

CPAP plus fridge, overnight (8 hours)about 6.9–8.3 hRuns out early

What the numbers mean for you

Gen 1 or Gen 2? This page covers the original SOLIX C1000: 1,056Wh, 1,800W continuous, 2,400W surge, expandable. The C1000 Gen 2 is a different product (1,024Wh, 2,000W, not expandable). If a listing quotes 2,000W for a 1,056Wh unit, it has mixed the two up.

On our estimate the C1000 runs a typical fridge for about 12 hours and Wi-Fi, lights and phones for about 12–13 hours. With the BP1000 fitted it would cover a fridge with Wi-Fi and lights through a 12-hour outage on our numbers. But when we checked on October 12, 2026, Anker’s own US storefronts disagreed on whether the BP1000 could be bought (one said sold out), so the planner doesn’t count the expansion until it’s clearly available.

SurgePad is Anker’s name for this model’s 2,400W surge capability — not an extra rating on top of it.

Sources: Anker SOLIX US product page: 1,056Wh, 1,800W continuous, 2,400W surge, 600W solar, 1,300W AC charging, 28.44 lb. This is Generation 1; the C1000 Gen 2 (1,024Wh, 2,000W) is a different product. BP1000 availability, checked 2026-10-12: us.ankersolix.com lists it as sold out, while ankersolix.com shows an add-to-cart button with no price. Because Anker's own storefronts conflict, the planner does not count the expansion. Manufacturer page.
