តើសាកថ្មនឹង ធនាគារថាមពល ធ្វើឱ្យខូចទូរស័ព្ទដែរឬទេ? ការពិតគឺនៅទីនេះ

 

តើអ្នកបានប្រើ ធនាគារថាមពល ? When the mobile phone is out of power, I know how happy it is to carry a ធនាគារថាមពល with you. When you are away from home, having a fully charged ធនាគារថាមពល at your fingertips will give you a sense of security. Although the ធនាគារថាមពល 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 ធនាគារថាមពល and other mobile power sources continue to occur, which is worrying. Is it really good to often use a ធនាគារថាមពល to charge a mobile phone? ហេតុអ្វីបានជាវាត្រូវចំណាយពេលច្រើនដើម្បីសាកក ធនាគារថាមពល? Can fast charging ធនាគារថាមពលs charge ordinary mobile phones? How should we use the ធនាគារថាមពល correctly?

Is it really good to often use a ធនាគារថាមពល to charge a mobile phone?

 

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

ហេតុអ្វីបានជាវាត្រូវចំណាយពេលច្រើនដើម្បីសាកក ធនាគារថាមពល?

 

បើប្រៀបធៀបទៅនឹងការសាកថ្មដោយផ្ទាល់ធនាគារថាមពល takes longer to fully charge the phone. This is because the ធនាគារថាមពល 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 ធនាគារថាមពលs 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 ធនាគារថាមពល 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 ធនាគារថាមពលs charge ordinary mobile phones?

 

Nowadays, many smart phones have the function of fast charging, and some ធនាគារថាមពលs 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. ធនាគារថាមពលs 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 ធនាគារថាមពល is still suitable for other mobile phones, but it cannot be fast charging.

How to use the ធនាគារថាមពល correctly?

 

1. When the charging is completed, the power supply of the ធនាគារថាមពល should be cut off in time to prevent overcharging.

 

 

2. Exposing the ធនាគារថាមពល 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 ធនាគារថាមពល.

 

 

3. Heavy pressure, beating and strong vibration will damage the inside of the ធនាគារថាមពល, so avoid bumping when using the ធនាគារថាមពល.

 

4. When the ធនាគារថាមពល is bulging, stop using the ធនាគារថាមពល.

 

នៅពេលបញ្ចូលថ្មធនាគារថាមពល, if the temperature of the ធនាគារថាមពល is found to be too high, stop charging immediately, and then charge again when the temperature drops to the normal temperature.
