The power bank circuit system is composed of five parts: aLithium Core Capacity Indication Circuit The lithium core capacity indication circuit consists of a voltage monitoring chip from the XC61CC series.
b.Cell protection circuit The cell protection circuit is composed of three parts: overcharge protection, over-discharge protection and over-temperature protection, and HAT2027, R5402, and self-recovery fuse build triple protection, which greatly enhances the safety of lithium cells. c.
Charging management circuit The charging management circuit adopts CN3066, which divides the charging process into four parts: trickle charging, constant current charging, constant voltage charging and maintenance charging, so that the mobile portable power supply can reserve energy to the greatest extent. Boost Circuit The DC-DC boost circuit uses the MAX1771 integrated chip, which can maximize the lithium core capacity within a safe range to achieve the purpose of powering a variety of digital devices. e.
Function Expansion Circuit The function extension covers the common needs involved in outdoor activities, with emergency night lighting, outdoor anti-theft security alarm, and camping mosquito repellent. In fact, the power bank is a large-capacity portable power supply that is convenient and easy to carry. It is a portable device that integrates power storage, boosting, and charging management.
The charging plug of the power bank itself can charge the mobile device directly through the AC power supply and has its own power storage device, which is equivalent to a hybrid of a charger and a backup battery, which can simplify the device of a charging plug compared to the backup power supply, and compared with the charger, it has its own power storage device, which can provide backup power for digital products when there is no direct power supply or when going out.

Note: What does the charger mean? The meaning is clear, because if you have something to do at the moment, this charger will help you.
-
I think it's a good note, and I'll tell you what I understand.
Mobile phones are now a daily must-have, when the power is used up, we have to charge, we have to use a charger to charge, and when I am unhappy, lack of energy or positive emotions, with the charger I can be resurrected again!
-
Even when you are tired, it will give you strength and support.
-
Just give him a note that it's a charger!

1 Input voltage: 100-240V 50-60Hz Output voltage means that the charger is equivalent to a converter. The current of 100-240V and 50-60 Hz is input into the charger, and after conversion, the current of the output voltage is transferred to the mobile phone battery. The meaning of 2 is similar to 1, which refers to the conversion of 110-220V voltage and 110 mA current, and the output is 5V voltage (up and down error 200-300 mA current output is expected to be adopted.
-
Input and indication input voltage range: 100 volts to 240 volts, input frequency: 50 Hz to 60 Hz. The size of the input current, the output is written sv--ss0ma should be the output voltage: 5 volts, and the output current: 550 mA.
The output current of this charger is less than the original (originally, it can be used now, but because the charging current is small, the charging time is greater than that of the original charger.)
-
The first line represents the output voltage and current of the battery itself, the second line indicates the appropriate temperature, and the third line indicates the efficiency level.
The fourth line is the connection between the environmental label and the battery, and the fifth line is the environmental protection requirements of the company's labeling and storage requirements.
-
Needless to say, the first line of sprinkles, input voltage and current, in the middle are some certification marks, and the same I don't know, the three circles should be the negative pole, the middle pole and the positive pole, and the bottom is some environmental protection logos. Tell you not to throw it in the general trash.
-
The interface of the two is the same, and the output voltage is the same.
bBecause the output current is larger, the charging time is shorter.
If it is a 1000mA battery, it will take about 3 and a half hours to fully charge with A, and about 2 hours and 15 minutes with B.
-
b Hurry up....Can be universal.
-
Output: 5V 800mA is usable. The lithium battery capacity is very small, and the requirements for the charger are very low, so it can be said that a charger can meet the requirements of use, as long as the interface is correct.
-
I think you're not active enough, isn't the charger only used when there is no power, and you just ignore it when there is power.
-
Say that you are not good to her, and only look for her when you need it, and only remember the charger when the phone is out of battery.
-
First there is AC and DC Then there is the model Then then the input voltage and then the input voltage plus current, AC or DC. Then there are the standards and can't be thrown in the trash and finally made in China.
If you are using a vivo charger, it is recommended not to continue to use the charger after it is liquidized to avoid safety accidents caused by short circuits. >>>More
Wireless charging technology is derived from wireless power transfer technology, which is based on the principle of transferring energy in a magnetic field between the charger and the electrical device. It can be divided into two types: low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction; High-power wireless charging often uses a resonant type, and the power supply device transmits energy to the power device.
There is an impact, because the capacity of MP4 batteries is very small, 500 mAh is much larger than 300 mAh, nearly twice as much, if you charge a 300 mAh battery with a 500 mAh charger, the battery will be charged, and sometimes it may be charged, the original charger It is designed for batteries, but don't worry, just use the charger you bought, and unplug the charger in time when you see it full. Estimate that your 500 mAh charger will charge a lot faster than your original charger ! Fast charging is not as good as slow charging!
1. The material is different.
The basic material of traditional ordinary chargers is silicon, which is also a very important material in the electronics industry. However, as the limit of silicon gradually approaches, and with the increase of fast charging power, the volume of the fast charging head is also larger, which is very inconvenient to carry; Some high-power chargers are also prone to cause charging hair heat when charging for a long time; Therefore, it is even more urgent to find new alternative materials. >>>More
For example, this one can be wirelessly charged for all wireless charging devices that support the Qi protocol, and this has a built-in three-coil to ensure that the phone can be charged normally if you put it on it at will, without deliberately aligning it. It is made of military-grade aramid fiber and aluminum alloy metal base, with fine workmanship and cutting, with a strong sense of design and modernity. >>>More
