FAQ
Which is better for day trips and camera charging?
AC180P 1440Wh has the portability advantage by listed weight, while DELTA 2 Max 2048Wh provides more stored energy. Pick the constraint that matters most for this use case.
Which model is the stronger fit for overnight backup planning?
DELTA 2 Max 2048Wh has the larger published capacity. Confirm that its 1800W AC rating also covers the starting and continuous load of your appliance.
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.
Can AC180P 1440Wh run a CPAP overnight?
At a 40W planning load with the humidifier off, the estimate is ~30 hours. Heated tubing or a humidifier can materially increase consumption.
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.
