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 Pioneer 150 (AC240) 1536Wh run a CPAP overnight?
At a 40W planning load with the humidifier off, the estimate is ~32 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?
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.
Which is better for a compact camp setup?
DELTA 2 Max 2048Wh 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.
