Anker SOLIX C1000 Gen 2 is a midsize (1 kwh class) model best suited to camper. It supplies 2,000 W of continuous AC output. BatteryRank scores it 68 out of 100 within its size class.
Our verdict on the Anker SOLIX C1000 Gen 2
The name suggests a straight upgrade and it is not one. Capacity actually falls slightly, 1,056 Wh down to 1,024 Wh, and the expansion port is gone — this pack is sealed for life. What you get instead is 2,000 W continuous where the first generation gave 1,800 W, 4,000 rated cycles against 3,000, a 10 ms switchover, and a 49-minute recharge. It is a better unit for someone who will never expand and a worse one for anyone who might.
- You want the unit to still be healthy in a decade of weekly use4,000 rated cycles is a third more than the generation it replaces, and at one full cycle a week that difference is roughly twenty years against fifteen.
- You want it to double as a desk charger for modern laptopsBoth USB-C ports run to 140 W, enough for a 16-inch laptop at full draw without touching the AC inverter and its conversion losses.
- A second battery is anywhere in your plansThere is no expansion port. The 1,024 Wh is permanent, and adding capacity later means buying a whole second unit. It starts at 2,048 Wh and expands to 4,096 Wh.
- You need to back up a 240 V appliance such as a well pump or a rangeThis is a 120 V unit with no split-phase support, so a 240 V circuit is not a stretch here but an impossibility. The F3800 supports 240 V split-phase output at 6,000 W.
The honest limit: Anker leads on the 2,000 W inverter, and it is genuine, but consider what it means against a 1,024 Wh pack: run the unit at its rated output and you empty it in about half an hour before losses. The output rating tells you what you can start, not how long you can keep it running, and those two questions have very different answers on this unit.
What our data can’t tell you: We hold no independent capacity measurement for the Gen 2 at all — the 81 percent figure in our data belongs to the first generation and cannot be transferred, since the cells and inverter both changed. Its real delivered energy is therefore unverified, and we would rather say so than assume the family behaves alike.

What it can run
Same sourced device assumptions used by our calculators, applied to this model's usable AC energy. Actual runtime varies with load, temperature, and standby draw.
| Device | Estimated runtime | Sourced assumption |
|---|---|---|
| CPAP (humidifier off) | about 12.1 nights | 9 W · |
| CPAP (heated humidifier on) | about 1.9 nights | 56 W · |
| Refrigerator (full-size) | about 14 hours | 180 W × 35% duty cycle · |
| Wi-Fi router + modem | about 48 hours | 18 W · |
| Laptop (65W charger) | about 27 hours | 65 W × 50% duty cycle · |

Who it fits
Mechanical matches against this model's own sourced specs — never invented sentiment, never a guess on a spec we don't have.
11.3 kg with 600 W solar input → carry-in, solar-rechargeable
870 Wh AC-delivered (est.) → multiple CPAP nights per charge
2000 W inverter, 870 Wh AC-delivered (est.) → runs a fridge through an outage

How this score is computed
The BatteryRank score is computed from sourced data with a published formula — ranked by data, not lab testing. Seven sub-scores blend into a 0–100 composite, grouped into four buyer pillars. Price is deliberately not a scoring input: prices move daily, so value intelligence lives in the price section above, judged against this model's own history.
| Pillar | Built from |
|---|---|
| Power | Capacity & expansion + Output & versatility |
| Trust | Trust & reliability + Durability & longevity |
| Charging | Charging & solar |
| Livability | Portability + Quiet / livability |
Scores are cohort-relative — each model is ranked against others in its size class. Missing inputs renormalize out rather than scoring zero (a model is never penalized for a spec nobody in its class publishes), and any figure resting on a documented estimate is tagged est.

Quick answers
Each answer restates a sourced figure from elsewhere on this page — nothing new, nothing guessed.
- How much does the Anker SOLIX C1000 Gen 2 weigh?
- 11.3 kg (24.9 lb), manufacturer-claimed, without accessories.
- What are the dimensions of the Anker SOLIX C1000 Gen 2?

- How much capacity does the Anker SOLIX C1000 Gen 2 deliver through an AC outlet?
- About 870 Wh of the rated 1,024 Wh reaches an AC outlet from a full charge — an estimate after our published 15% inverter-loss constant (marked est. on this page).
- How long does the Anker SOLIX C1000 Gen 2 take to charge?
- 49 min from a wall outlet, 0 to 100%, manufacturer-claimed. Fast-charge modes and solar input differ — see the charging specs on this page.
- How many watts can the Anker SOLIX C1000 Gen 2 output?
- 2,000 W continuous AC output and 3,000 W surge output, manufacturer-claimed. Appliance startup demand must stay within the relevant limit.
- How much solar input can the Anker SOLIX C1000 Gen 2 accept?
- 600 W maximum solar input, manufacturer-claimed. Actual harvest depends on panel compatibility, sun, orientation, temperature, and conversion losses.
- What is the cycle-life rating of the Anker SOLIX C1000 Gen 2?
- 4,000 cycles to 80% remaining capacity, manufacturer-claimed. A cycle rating is not a calendar-life guarantee.
- Can the Anker SOLIX C1000 Gen 2 work as a UPS?
- Its manufacturer-claimed transfer time is 10 ms. Confirm that your connected equipment tolerates that transfer time; this is not the same as a zero-transfer online UPS.
