Which one runs a fridge longer?

The S2000. Its 2,010Wh capacity keeps a fridge running for about 35 hours, roughly double what a 1kWh C1000 can do.

Can the C1000 Gen 1 run a space heater?

No. Its 1,000W output is below most space heaters, which draw 1,500W. The S2000's 1,500W continuous rating can handle one.

Is the S2000 worth the extra money?

Yes if you need whole-home backup or RV power. The extra capacity, 1,500W output and 10,000-cycle cells justify the price. For camping and phone charging, the C1000 is enough.

The S2000. Anker rates its LFP cells at up to 10,000 cycles, about a 15-year lifespan. The C1000 class is rated for roughly 3,000 cycles.

Which is easier to carry?

The C1000 Gen 1, at about 29 lb versus 35.7 lb for the S2000. Neither is a one-hand carry for most people.

Can either power an RV?

Only the S2000 has a 30A RV outlet. The C1000 needs an adapter and cannot match the S2000's output.
