An outdoor power supply is a portable device that can provide power for various electrical appliances. It allows you to enjoy a comfortable life outdoors without a socket. However, do you know what the power and capacity of an outdoor power supply mean? These two parameters are very important for choosing a suitable outdoor power supply. Let us explain it to you below.

Power of an outdoor power supply

The power of an outdoor power supply refers to the maximum power it can output, in watts (W). The power of an outdoor power supply determines the types of electrical appliances that can be used. For example, an outdoor power supply with a rated power of 1800W can drive electrical appliances below 1800W. If you want to use electrical appliances with a power of more than 1800W, such as air conditioners, microwave ovens, etc., you need to choose an outdoor power supply with a higher power.

So, how do you calculate the power of the outdoor power supply you need? Generally speaking, you can estimate it according to the following formula:

Outdoor power supply power = maximum load power × 1.2

Among them, the maximum load power refers to the sum of the power of all electrical appliances you use at the same time. Multiplying by 1.2 is to leave a certain margin to avoid damage caused by overload. For example, if you use a 100W light bulb and an 800W hair dryer at the same time, the maximum load power is 900W, so you need at least a 1080W (900W x 1.2) outdoor power supply.

Capacity of outdoor power supply

The capacity of an outdoor power supply refers to the maximum amount of electricity it can store, in ampere-hours (Ah) or watt-hours (Wh). The capacity of an outdoor power supply determines the length of time that the power can be used. The larger the capacity, the more power it can provide, and the longer it can be used. For example, an outdoor power supply with a capacity of 500Wh can power a 100W light bulb for 5 hours (500Wh / 100W = 5h).

So, how do you calculate the capacity of an outdoor power supply you need? Generally speaking, you can estimate it according to the following formula:

Outdoor power supply capacity = average load power × usage time

Among them, the average load power refers to the average power consumed per hour during use. Usage time refers to the total time you expect to use the outdoor power supply. For example, if you use an average of 200W of electrical appliances per hour and want to use them for 10 hours, you will need at least a 2000Wh (200W x 10h) outdoor power supply.

Summary

Through the above introduction, I believe you have a clear understanding of what the outdoor power supply means. When choosing an outdoor power supply, you need to determine the appropriate power and capacity based on the type of electrical appliances you use and the time of use.
