There are many types of power station calculators, but the most important task they need to solve is to calculate whether your home power station or the power station you plan to buy can meet your device and electrical needs. The following power station calculation formula is precisely established for this purpose.

How to use a calculation formula?
Before using the formula, you need to be clear about which appliances you need to use, what their rated power is, and what the battery capacity of your power station is. Follow these steps:
Fill in the data according to your actual situation in the calculation formula above.
Click “Calculate” to display how many hours your power station can power these appliances.
Based on this result, it is recommended to choose a power station product with a power capacity greater than the total power of the appliances, typically greater than 25% for optimal performance.
How to check electrical power wattage?
The method for checking the power of an appliance depends on the type of appliance. Typically, the rated power of an appliance can be found in the product’s manual or label. If the manual or label is not available, you can try searching for the rated power information of the product model on the internet. Additionally, you can use a power meter to measure the actual power consumption of the appliance. Plug the power meter in between the appliance and the power source, then turn on the appliance and use it, and the power meter will display the actual power consumption of the appliance.
How to calculate the total electrical power wattage?
To calculate the total power consumption of appliances, you need to consider the rated power of each appliance and the duration of their use. The total power consumption of appliances can be calculated using the following formula:
Total Power Consumption = (Appliance 1 Rated Power × Appliance 1 Duration) + (Appliance 2 Rated Power × Appliance 2 Duration) + … + (Appliance n Rated Power × Appliance n Duration)
Here, Appliance 1, Appliance 2, …, Appliance n represent each appliance with known rated power and duration of use.
For example, if you need to calculate the total power consumption of two appliances, one with a rated power of 1000 watts and a duration of use of 2 hours, and another with a rated power of 500 watts and a duration of use of 3 hours, then the total power consumption of the appliances would be:
Total Power Consumption = (1000 × 2) + (500 × 3) = 3000 watts
Therefore, in this example, the total power consumption of the two appliances is 3000 watts.
How to choose the Power station according to their electrical needs?
To choose a portable power station that suits your appliance needs, consider the following factors:
Rated Power: Check the rated power of the appliances you need to use, and then choose a power station with a power level higher than the total power consumption of your appliances to ensure that it can operate normally.
Battery Capacity: Battery capacity is an indicator of the amount of electrical energy that a power station can store. Choose a power station with a capacity higher than the required usage time to ensure that the power source can last.
Output Ports: Check the plug type of the appliances you need to use and ensure that the power station has the corresponding output ports.
Weight and Size: Consider the usage environment and mobility and choose a power station that suits your size and weight.
Additional Functions: Some power stations have additional functions, such as LED lights, solar charging, etc., which can be chosen according to personal needs.
In summary, choosing a power station that meets your needs in terms of power level, battery capacity, output ports, weight and size, and additional functions according to your appliance requirements is the best choice.
How to calculate the Power supply time of a Power station?
To calculate the power supply time of a power station, you need the following data:
Power station battery capacity (Ah or Wh).
Total power consumption of the devices that need to be powered (W).
Output power of the power station (W).
Use the following formula to calculate the power supply time of the power station (in hours):
Power Supply Time = Power Station Battery Capacity ÷ Total Power Consumption of Devices × 0.85
Here, 0.85 is a coefficient that takes into account battery loss and power conversion efficiency, which is generally set to 0.85.
For example, if your power station battery capacity is 100Wh and the total power consumption of the devices you need to use is 50W, then the power supply time is:
Power Supply Time = 100 ÷ 50 × 0.85 = 1.7 hours
Therefore, in this example, the power supply time of the power station is 1.7 hours.
How to calculate the charging time of the Power station?
To calculate the charging time of a power station, you need the following data:
Power station battery capacity (Ah or Wh).
Output current of the charger (A).
Charging efficiency of the power station (usually 0.85).
Use the following formula to calculate the charging time of the power station (in hours):
Charging Time = Power Station Battery Capacity ÷ Output Current of Charger × Charging Efficiency
For example, if your power station battery capacity is 100Wh, the output current of the charger is 2A, and the charging efficiency is 0.85, then the charging time is:
Charging Time = 100 ÷ 2 × 0.85 = 42.5 hours
Therefore, in this example, the charging time of the power station is 42.5 hours.
It should be noted that this is just a rough estimate, and the actual charging time will be affected by other factors such as the quality of the charger, the health of the battery, temperature, etc.
