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 Elite 400 3840Wh run a CPAP overnight?
At a 40W planning load with the humidifier off, the estimate is ~81 hours. Heated tubing or a humidifier can materially increase consumption.
Can AC180P 1440Wh 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 ~20 hours.
Which model is the stronger fit for multi-device camp use?
Elite 400 3840Wh has the larger published capacity. Confirm that its 2600W AC rating also covers the starting and continuous load of your appliance.
Which is better for short outage essentials?
AC180P 1440Wh has the portability advantage by listed weight, while Elite 400 3840Wh provides more stored energy. Pick the constraint that matters most for this use case.
