Umetumia faili ya Benki ya nguvu ? When the mobile phone is out of power, I know how happy it is to carry a Benki ya nguvu with you. When you are away from home, having a fully charged Benki ya nguvu at your fingertips will give you a sense of security. Although the Benki ya nguvu 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 Benki ya nguvu and other mobile power sources continue to occur, which is worrying. Is it really good to often use a Benki ya nguvu to charge a mobile phone? Kwa nini inachukua muda mwingi kulipia Benki ya nguvu? Can fast charging Benki ya nguvus charge ordinary mobile phones? How should we use the Benki ya nguvu correctly?
The Benki ya nguvu 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 Benki ya nguvus use 3.7V lithium batteries as batteries. The charging input of the Benki ya nguvu is 5V DC, and the output is reversed. The average working voltage of the Benki ya nguvu’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 Benki ya nguvu (except cottage Benki ya nguvus) will basically not cause direct damage to the mobile phone.
Ikilinganishwa na kuchaji moja kwa moja,Benki ya nguvu takes longer to fully charge the phone. This is because the Benki ya nguvu 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 Benki ya nguvus 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 Benki ya nguvu 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 Benki ya nguvus 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. Benki ya nguvus 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 Benki ya nguvu is still suitable for other mobile phones, but it cannot be fast charging.
1. When the charging is completed, the power supply of the Benki ya nguvu should be cut off in time to prevent overcharging.
2. Exposing the Benki ya nguvu 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 Benki ya nguvu.
3. Heavy pressure, beating and strong vibration will damage the inside of the Benki ya nguvu, so avoid bumping when using the Benki ya nguvu.
4. When the Benki ya nguvu is bulging, stop using the Benki ya nguvu.
Wakati wa kuchajiBenki ya nguvu, if the temperature of the Benki ya nguvu is found to be too high, stop charging immediately, and then charge again when the temperature drops to the normal temperature.
