In the era of never leaving the body, the power bank is basically one of the mobile phone accessories that we often use in our lives as an extension of the battery life of mobile phones. Going out, having a power bank with sufficient power to use will make you feel full of security, but is it really good to use a power bank to charge your mobile phone often? Let's explore together!

The structure of the power bank

The power bank consists of three parts: shell, battery and circuit board. The shell protects the battery cell and the circuit board; the size of the battery cell determines the power level; the quality of the circuit board is related to the discharge effect and conversion rate of the power bank.

The power bank is a charging device that integrates power storage, buck, boost, and charging management, and can assume the function of a charger and a backup battery. Power banks generally use lithium batteries as power storage units, which are convenient and fast to use, and can be used to charge digital devices such as mobile phones and tablet computers anytime, anywhere.

The charging principle of the power bank

The principle of the power bank is similar to that of the charging connector. It charges the mobile phone after adjusting the voltage to about 3.7V. When charging the mobile phone, the circuit: board will adjust the voltage of the charging treasure itself according to the input voltage supported by the mobile phone, so using a regular brand of charging treasure to charge the mobile phone will usually not damage the mobile phone.

Knowing the structure and charging principle of the power bank, the editor of Saiyue Technology has also sorted out a few questions about the daily use of the power bank to see if it is you!

A few doubts about the power bank

1. Why is the charging time of the power bank longer?

The power bank uses the USB interface to charge the mobile phone. Compared with charging with the charger, the output current of the power bank is smaller and the current loss is large, so the charging time of the power bank is longer.

2. Is the power of the mobile phone charged with the power bank not durable?

The length of battery life depends on whether the power of the charging treasure and the mobile phone match. If the power of the charging treasure and the mobile phone do not match, the phenomenon of false power of the mobile phone will occur.

3. How to choose a power bank?

Buy a power bank with 3C certification.

For the power bank of the same power, you should choose to buy a power bank of a big brand.

Check the input voltage and current marked on the mobile phone charger, compare the input and output current on the power bank, and choose the power bank that suits you.

4. How to use the power bank correctly?

When the charging is completed, the power supply of the power bank needs to be cut off in time to avoid accidents.

Using the power bank at high temperatures will deform the internal battery, and using it in an environment that is too humid is likely to short-circuit it. It is recommended to store the power bank in a dry and ventilated place.

Heavy pressure, beating and strong vibration will damage the internal parts of the power bank, which may cause a short circuit in the power bank. It is recommended to be cautious when using the power bank and place it properly after use.
