How to calculate the usage time of portable power station power?

There are several situations when the portable power station supplies power to electrical equipment; for example, there are many situations such as charging and discharging products with batteries, and equipment without batteries.

Taking the 1500Wh partastar portable power station as an example, let me briefly explain how the power of the portable power station is used to calculate the usage time?

How to calculate the power supply duration of the portable power station?

1. Calculation of the number of times of use (for devices with batteries turned off, such as mobile phones, notebooks, etc.): portable power station*0.85/electric energy of electrical equipment

For example: 60W laptop with power loss: 1500Wh*0.85/60Wh≈21 times

2. Calculation method for charging while using the battery: electric energy*0.5/equipment electric energy

For example: 66w tablet computer (use while charging): 1500Wh*0.5/66Wh≈11 times

3. Calculation of power supply time (equipment without battery, such as: projector, desktop computer, etc.): portable power station capacity*0.8/equipment output power

For example: 60W projector (without battery): 1000Wh*0.8/60Wh≈13.3 hours

4. Why is the power consumption of the portable power station not 1500Wh/50Wh=75 times? Because when we use the portable power station, the cooling fan, inverter and other accessories in the portable power station are also working at the same time, so after many tests, the final approximate calculation formula is obtained.
