Everyone uses mobile smart phones every day, and a dead phone will make you very distressed. This has led to the emergence of mobile power supplies, and they are very popular. Because it can continue to provide power to your electronic devices when you are away from the wall socket. And when you go to travel, some electronic devices will definitely not be able to provide the electricity you need for travel, so “it” can help you solve it. Do you know what is called power bank?
The portable power bank is controlled by a special battery and a special circuit under special circumstances. They allow you to store electrical energy and then use it to charge mobile devices. And the mobile power source may also be called a power station or battery pack.
There are three main types of power banks found on the market today:
1. Universal power bank. They are available in a variety of sizes and configurations, which can be customized according to your equipment requirements and budget.
2. Solar power bank. They have photovoltaic panels that can trickle charge the internal batteries in the sun. Solar charging is not fast, so they can usually be charged via cable.
3. The third type of power bank is the old battery phone case. Although they are convenient, the device compatibility of this type of power bank is very limited.
What we are talking about here is the mobile power bank that everyone often sees or uses frequently. It is suitable for almost all USB charging devices. Cameras, GoPros, portable speakers, GPS systems, MP3 players, smartphones and even some tablets can be charged by power banks-almost everything that is charged by USB at home can be charged by power banks! And generally ordinary mobile power can support your mobile phone several times from zero to 100% power. But it depends on the specifications and capacity of your mobile power supply, and then combined with your mobile device, this can clearly calculate how long the mobile power supply can provide power for your mobile device!
