మీరు ఉపయోగించారా? పవర్ బ్యాంక్ ? When the mobile phone is out of power, I know how happy it is to carry a పవర్ బ్యాంక్ with you. When you are away from home, having a fully charged పవర్ బ్యాంక్ at your fingertips will give you a sense of security. Although the పవర్ బ్యాంక్ 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 పవర్ బ్యాంక్ and other mobile power sources continue to occur, which is worrying. Is it really good to often use a పవర్ బ్యాంక్ to charge a mobile phone? వసూలు చేయడానికి ఎందుకు సమయం తీసుకుంటుంది a పవర్ బ్యాంక్? Can fast charging పవర్ బ్యాంక్s charge ordinary mobile phones? How should we use the పవర్ బ్యాంక్ correctly?
The పవర్ బ్యాంక్ 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 పవర్ బ్యాంక్s use 3.7V lithium batteries as batteries. The charging input of the పవర్ బ్యాంక్ is 5V DC, and the output is reversed. The average working voltage of the పవర్ బ్యాంక్’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 పవర్ బ్యాంక్ (except cottage పవర్ బ్యాంక్s) will basically not cause direct damage to the mobile phone.
డైరెక్ట్ ఛార్జింగ్తో పోలిస్తే, దిపవర్ బ్యాంక్ takes longer to fully charge the phone. This is because the పవర్ బ్యాంక్ 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 పవర్ బ్యాంక్s 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 పవర్ బ్యాంక్ 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 పవర్ బ్యాంక్s 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. పవర్ బ్యాంక్s 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 పవర్ బ్యాంక్ is still suitable for other mobile phones, but it cannot be fast charging.
1. When the charging is completed, the power supply of the పవర్ బ్యాంక్ should be cut off in time to prevent overcharging.
2. Exposing the పవర్ బ్యాంక్ 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 పవర్ బ్యాంక్.
3. Heavy pressure, beating and strong vibration will damage the inside of the పవర్ బ్యాంక్, so avoid bumping when using the పవర్ బ్యాంక్.
4. When the పవర్ బ్యాంక్ is bulging, stop using the పవర్ బ్యాంక్.
ఛార్జింగ్ చేసినప్పుడుపవర్ బ్యాంక్, if the temperature of the పవర్ బ్యాంక్ is found to be too high, stop charging immediately, and then charge again when the temperature drops to the normal temperature.
