Да ли сте користили а Повер банк ? When the mobile phone is out of power, I know how happy it is to carry a Повер банк with you. When you are away from home, having a fully charged Повер банк at your fingertips will give you a sense of security. Although the Повер банк is easy to use, it has a "violent temper". With the advent of the era of a mobile phone, the safety accidents caused by the Повер банк and other mobile power sources continue to occur, which is worrying. Is it really good to often use a Повер банк to charge a mobile phone? Зашто је пуњење а-а дуготрајно Повер банк? Can fast charging Повер банкs charge ordinary mobile phones? How should we use the Повер банк correctly?
The Повер банк is a charging device that integrates power storage, step-down, step-up, and charging management. It functions as a charger and a backup battery. Like mobile phones, most Повер банкs use 3.7V lithium batteries as batteries. The charging input of the Повер банк is 5V DC, and the output is reversed. The average working voltage of the Повер банк’s cells is 3.7V, boosted to the output working voltage of 5V and then transmitted to the mobile phone to achieve the charging effect. In this process, as long as the battery voltage is stable, the charging of the mobile phone is stable and will not cause damage to the mobile phone. Therefore, charging a mobile phone with a regular Повер банк (except cottage Повер банкs) will basically not cause direct damage to the mobile phone.
У поређењу са директним пуњењем,Повер банк takes longer to fully charge the phone. This is because the Повер банк uses USB for charging. Compared with the AC power of the charger, the current output is small, so it will basically lose some current. In addition, some Повер банкs have thinner wires, and the resistance of the wires is too large, which will also cause the charging speed to drop. Another situation is that the battery quality of the Повер банк itself is too poor. In order to stabilize the current to control the output, it will also cause the charging time to become longer.
Nowadays, many smart phones have the function of fast charging, and some Повер банкs that support fast charging have appeared. However, there are many fast charging protocols for mobile phones, and mobile phone chargers of different protocols cannot be used universally. Повер банкs that support fast charging is also like this. However, non-universal means that mobile phones with different fast charging protocols can only use the mobile power corresponding to the fast charging protocol to have the fast charging effect. But the fast charging Повер банк is still suitable for other mobile phones, but it cannot be fast charging.
1. When the charging is completed, the power supply of the Повер банк should be cut off in time to prevent overcharging.
2. Exposing the Повер банк to high temperatures may deform the internal battery, and placing it in a humid environment may short-circuit the internal battery, so pay attention to the environment when storing and using the Повер банк.
3. Heavy pressure, beating and strong vibration will damage the inside of the Повер банк, so avoid bumping when using the Повер банк.
4. When the Повер банк is bulging, stop using the Повер банк.
Приликом пуњењаПовер банк, if the temperature of the Повер банк is found to be too high, stop charging immediately, and then charge again when the temperature drops to the normal temperature.
