Koj puas tau siv a Sij hawm thaum fais fab tuag ? When the mobile phone is out of power, I know how happy it is to carry a Sij hawm thaum fais fab tuag with you. When you are away from home, having a fully charged Sij hawm thaum fais fab tuag at your fingertips will give you a sense of security. Although the Sij hawm thaum fais fab tuag 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 Sij hawm thaum fais fab tuag and other mobile power sources continue to occur, which is worrying. Is it really good to often use a Sij hawm thaum fais fab tuag to charge a mobile phone? Vim li cas nws yog lub sijhawm siv sijhawm ntau los them a Sij hawm thaum fais fab tuag? Can fast charging Sij hawm thaum fais fab tuags charge ordinary mobile phones? How should we use the Sij hawm thaum fais fab tuag correctly?

Is it really good to often use a Sij hawm thaum fais fab tuag to charge a mobile phone?

 

The Sij hawm thaum fais fab tuag 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 Sij hawm thaum fais fab tuags use 3.7V lithium batteries as batteries. The charging input of the Sij hawm thaum fais fab tuag is 5V DC, and the output is reversed. The average working voltage of the Sij hawm thaum fais fab tuag’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 Sij hawm thaum fais fab tuag (except cottage Sij hawm thaum fais fab tuags) will basically not cause direct damage to the mobile phone.

Vim li cas nws yog lub sijhawm siv sijhawm ntau los them a Sij hawm thaum fais fab tuag?

 

Piv rau kev them nyiaj ncaj qha, tusSij hawm thaum fais fab tuag takes longer to fully charge the phone. This is because the Sij hawm thaum fais fab tuag 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 Sij hawm thaum fais fab tuags 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 Sij hawm thaum fais fab tuag itself is too poor. In order to stabilize the current to control the output, it will also cause the charging time to become longer.

Can fast charging Sij hawm thaum fais fab tuags charge ordinary mobile phones?

 

Nowadays, many smart phones have the function of fast charging, and some Sij hawm thaum fais fab tuags 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. Sij hawm thaum fais fab tuags 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 Sij hawm thaum fais fab tuag is still suitable for other mobile phones, but it cannot be fast charging.

How to use the Sij hawm thaum fais fab tuag correctly?

 

1. When the charging is completed, the power supply of the Sij hawm thaum fais fab tuag should be cut off in time to prevent overcharging.

 

 

2. Exposing the Sij hawm thaum fais fab tuag 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 Sij hawm thaum fais fab tuag.

 

 

3. Heavy pressure, beating and strong vibration will damage the inside of the Sij hawm thaum fais fab tuag, so avoid bumping when using the Sij hawm thaum fais fab tuag.

 

4. When the Sij hawm thaum fais fab tuag is bulging, stop using the Sij hawm thaum fais fab tuag.

 

Thaum them covSij hawm thaum fais fab tuag, if the temperature of the Sij hawm thaum fais fab tuag is found to be too high, stop charging immediately, and then charge again when the temperature drops to the normal temperature.
