How long does a portable power station last for power supply? I think this is a question that many people who are planning to purchase portable power stations want to ask. Next, I will share with you the time I know that a portable power station can continue to supply power.

Factors that determine the frequency of continuous power supply for portable power stations

In fact, how long does a portable power station last is determined by many factors, such as power, battery capacity, the power of the powered appliance, temperature, and the type of battery in the portable power station. Moreover, different specifications of portable power stations can store different amounts of electricity. How do these factors affect the continuous power supply time of portable power stations? Next, we will analyze each of these factors one by one.

1. Battery capacity: The larger the capacity of a portable power station, the longer the power supply can usually be provided. The common units of capacity are milliampere hours (mAh) or watt hours (Wh).

2. Output power: If you connect multiple devices or use high-power devices at the same time, the power supply time of the portable power station may be shortened because the output power consumption is faster.

3. The power consumption of connecting devices: Different devices consume different amounts of electricity during use. For example, mobile phones typically consume less power than tablets. So, generally, the higher the power of an electrical appliance, the greater the power consumption, and the shorter the continuous power supply time of a portable power station.

4. Charging efficiency: the charging efficiency of portable power station itself will also affect the power supply time. Higher charging efficiency means less energy loss, and more electric energy can be enriched under the same input power.

5. The type of battery used to manufacture portable power stations: Due to different types of batteries, their work efficiency may also vary, such as lead-acid batteries, LiFepo4 batteries, and ternary lithium batteries. Their continuous power supply often varies to some extent.

6. External temperature conditions: Generally in cold seasons, the battery activity is not as strong as in summer. Portable power stations provide power to appliances of the same power, and the continuous power supply time in summer is generally longer than that in winter.

Therefore, to determine the power supply duration of a portable power station, you need to consider the above factors and look up the specifications of the relevant products. These specifications usually provide specific power supply time ranges or typical power supply times, but please note that the actual usage of portable power stations may vary depending on the usage conditions and environment.

A Simple Method for Calculating the Continuous Power Supply Time of a Portable Power Station

So, is there a way to know the continuous power supply of a portable power station when we only need to see its specifications? I can give you a positive answer.

Assuming you see a portable power station vendor selling a portable power station with a power of 150W and a battery capacity of 150WH, you can calculate the duration of the portable power station's continuous power supply. If you have a 150W appliance and the 150W portable power station is fully charged, This portable power station can provide up to 1 hour of power to your 150W appliances. Of course, for safety reasons and the need to extend battery life, generally all portable power stations will automatically remind of low battery power and issue a low battery alarm when the battery consumption is about 80%. Therefore, in fact, it can continuously power 150W appliances for about 50 minutes.

If it is a 5W energy-saving light bulb or a mini electric fan, then this portable power station can work continuously for about 30 hours.

What about using this portable power station in winter? Due to the significant loss of electricity in winter, this 150W portable power station will provide shorter continuous power supply to 150W appliances.

So, if we know the power and capacity of a portable power station, and also know the power of the continuously powered appliances, we can basically calculate how long does a portable power station last. Just divide the capacity of How long does a portable power station last by the power of the supplied electrical appliance, and the result is How long does the portable power station last.
