The mobile power supply is very fast and convenient to use. It can provide enough power to the mobile phone when the mobile phone is not powered, but the mobile power supply also needs to be charged. So how is the mobile power source charged? What problems will you encounter when charging mobile power?
Many friends who have used mobile power for the first time have encountered this problem: how to charge the mobile power. In fact, the charger for mobile power is not found, it is not a business leak, this is normal, if the input voltage and current of the mobile power supply is: 5V/500mAh, then generally there is no built-in charger, you can use the computer USB interface to move Power charging, because the output voltage and current of the computer USB interface is exactly 5V/500mAh, the input interface of the mobile power supply is generally Micro USB, so just use one end of the USB and the other end is the Micro USB cable to connect the mobile power to the working computer. On the desktop (both desktop and laptop) you can charge your mobile power. The charging methods of various mobile power sources on the market are similar. First, you need to select the charger or use the computer USB to fully charge the mobile power. Then, according to the interface of your own mobile phone, select the corresponding converter to charge the mobile phone. The mobile power supply generally has two output interfaces. When charging the mobile phone, 5V/1A is generally selected; while the tablet computer generally uses 5V/1.5A-2A.
How is the mobile power supply fully charged?
There are generally 4 LED lights on the mobile power supply, namely the charging status indicator. When charging, the LED light will flash, and according to the amount of power, gradually increase the number of flashes from 1-4 lights. When all four LEDs are lit up and stop flashing, it means full.
Charged the mobile power supply with the charger for a long time, not full? what is the reason?
1. The length of the charging time is not only related to the output current when the charger is charging the mobile power source, but also related to the capacity of the battery used by the mobile power source. The output current of the charger is unchanged. The higher the capacity of the mobile power supply, the longer it takes to fully charge. Similarly, the capacity of the mobile power supply is unchanged, and the smaller the output current of the charger, the longer it takes to fully charge.
2. If you plug directly into the computer's USB port to charge the mobile power, the time will be longer, because the computer USB interface output current is very small.
How to calculate the number of times the mobile power source charges the mobile phone?
1. First of all, it must be clear that the calculation method of this charging frequency is wrong. It is not possible to simply divide the battery capacity of the mobile power source by the battery capacity of the mobile phone.
2. The capacity identified by all mobile power products refers to the capacity of the internal lithium-ion battery, not the capacity that can be released when the mobile power source charges the battery.
3. The battery voltage of communication equipment or digital products is nominally 3.7V, and the full charge is 4.2V. The nominal voltage of the lithium-ion battery built in the mobile power supply is also 3.7V, and the full-charge is 4.2V. The voltage range of the mobile power supply is Can't charge the battery directly.
4. The mobile power supply must automatically boost the voltage of the built-in polymer battery of the mobile power supply to the charging voltage required by the external charging device through the built-in intelligent boost circuit, which is generally 4.2V-5V. This process of boosting will result in A part of the loss; plus a part of the capacity loss of the circuit and the connector during the charging process, so the capacity of the mobile power output is not as high as the capacity of the built-in polymer battery. It is not correct to directly and simply divide the capacity of the mobile power source by the capacity of the mobile phone battery to obtain the number of times of charging.
Charging the phone with mobile power, will it burn the phone?
The mobile power supply is precisely designed. It uses ATL polymer batteries and intelligent power management chip. The output voltage is constant, the current is stable, and it has automatic protection device. It will never cause any damage to mobile phones and other equipment.
Mobile power can not be charged? The light is not lit?
If this happens, please continue to charge the mobile power according to the correct charging method. After a while, the light will light up and enter the normal charging state.
Why can't I charge my phone?
Because some mobile phones use the original data cable to connect the mobile phone and mobile power, it can not charge or generate virtual charging. If this is the case, please use the charging data cable delivered by the mobile phone. If you still can't charge, please contact the merchant for after-sales service.
The mobile power supply is hot during use, is it normal?
When the mobile power source is charging itself or discharging externally, the energy is in the process of conversion, and it is normal to have a slight heat generation phenomenon.
Now everyone understands how mobile power is charged! Hurry up and get your mobile power fully charged!
