Method: nameplate capacity x 0.85 / device watts. The 15% allowance represents typical conversion and system overhead for planning. Actual duration depends on load behavior, temperature, battery state, and power mode.

FAQ

How are the runtime estimates calculated?

Each estimate uses 85% of the nameplate watt-hour capacity, then divides by the stated device load. It is planning math based on specifications, not a measured result.

Can SOLIX C2000 Gen 2 2048Wh run a CPAP overnight?

At a 40W planning load with the humidifier off, the estimate is ~43 hours. Heated tubing or a humidifier can materially increase consumption.

Can DELTA 2 Max 2048Wh run a refrigerator?

Its listed AC output is 1800W. If the refrigerator's running and startup demand stay below that limit, the planning estimate at a 60W average load is ~29 hours.

Which model is the stronger fit for refrigerator and router support?

Tie has the larger published capacity. Confirm that its 4000W AC rating also covers the starting and continuous load of your appliance.

Which is better for a compact camp setup?

SOLIX C2000 Gen 2 2048Wh has the portability advantage by listed weight, while Tie provides more stored energy. Pick the constraint that matters most for this use case.
