Anker SOLIX C2000 Gen 2 vs BLUETTI AC240
These are not the same class. One carries noticeably more battery than the other, so this is really a question about how much power you need rather than which brand builds better.
One is a size up
Anker SOLIX C2000 Gen 2 holds around a third more battery — 2,048Wh against 1,536Wh — and that is what decides how long either one lasts on the same load.
Anker SOLIX C2000 Gen 2 is 31 lb lighter, which at this size is the difference between carrying it and moving it.
BLUETTI AC240 takes 1,200W of solar against 800W, which only matters if a panel is your way back to full — and matters a great deal if it is.
BLUETTI AC240 refills faster from the wall, accepting 2,200W against 1800W.
Anker SOLIX C2000 Gen 2 is rated for more charge cycles (4000 Cycles against 3,500+ cycles to 80%) — though makers do not all test to the same remaining capacity, so read those two numbers side by side rather than as a ranking.
Drawn from 7 specifications each maker publishes, of which 7 differ. We have not handled either machine — see our methodology.

What the extra battery buys you
Watt-hours are hard to picture, so here is each pack as runtime on the loads a machine this size is usually bought for. Both columns assume 85% inverter efficiency — the conservative end of what these are rated at — so read every figure as a floor.
| Load | Anker SOLIX C2000 Gen 2 | BLUETTI AC240 |
|---|---|---|
| Full-size fridge (150W average) | 12 hours | 8.7 hours |
| Chest freezer (100W average) | 17 hours | 13 hours |
| Gas furnace blower (400W) | 4.4 hours | 3.3 hours |
| Sump pump, intermittent (300W average) | 5.8 hours | 4.4 hours |
| Space heater on low (750W) | 2.3 hours | 1.7 hours |
From solar alone, at 70% of the panel input each maker quotes — a realistic day rather than a lab figure — the Anker SOLIX C2000 Gen 2 needs about 3.7 hours of good sun to refill , and the BLUETTI AC240 about 1.8 hours.
Published by only one of them
A figure missing from a spec sheet is not a zero — it is a number the maker chose not to state. These appear on one page and not the other, so they cannot be compared, only noted.

Where this comparison stops
Everything above is what the makers publish, not what either machine did in front of us. We own neither, so there is no noise measurement, no thermal behaviour under sustained load, and no view on how either holds up after two years. Makers also measure differently — cycle life at 80% capacity is not the same test as cycle life at 70% — so figures that look comparable sometimes are not. Treat this as a way to build a shortlist quickly, and read the caveats on our methodology page before you let a number decide.

Neither figure above is a price. These two move independently and often, and whichever is discounted this week is usually the answer when the specifications are as close as they are here.
