Universal charging does not necessarily have the function of full stop, so do not remove the protection plate.
Question 1: Can the smartphone battery workUniversal charge can be charged, but it is not recommended to use universal charge. Universal charger has good compatibility, but in order to produce qualified products must use special computing chips and detection circuits, such products do not want to win the comprehensive cost of 100 yuan.
Universal charger is also divided into positive and negative terminals, at present, many universal chargers have automatic detection function inside, when the battery is detected, it automatically adjusts the circuit to change the positive and negative terminals to meet the power supply needs. There is also a need to manually flip the switch to convert the positive and negative poles.
The 18650 battery cannot be charged directly. 18650 battery nominal electricityThe voltage is 7V, and the cut-off voltage for charging is 2V. The charger output voltage of our usual mobile phone is 5V, now most of the chargers are fast charge, the output voltage can be 9V/12V, only when the fast charge protocol handshake is successful, the output voltage is such.
Charge the lithium iron phosphate battery with a 6V lithium battery, and the 6V lithium battery can be charged with a universal charger. The 4V battery is connected to the germanium diode (voltage drop of about 0.3V), and the 4V battery and charging circuit can be obtained by buying a charging flashlight. USB's 5V DC output is connected in series to two silicon diodes, each silicon diodeLong. Depending on how you like it. If you have two batteries, a charger is fine.
2, direct charging: that is, line charging ··· Only the transformer and the plug connected to the mobile phone ·· can not put the battery charging separately (generally the original machine is standard, there are also anti) charger: there is a simple battery card slot seat, without the help of the mobile phone, the battery can be removed and charged separately on the above, in the case of more than two batteries.
3, direct, according to the query of Huaqiang electronic network display. Direct charge is fast charge, long charging time, safe and reliable charging process, but it will have a certain adverse impact on the battery life. The charger is used to charge another battery during the use of the mobile phone, which needs to be connected to the original charger, which is the safest and most reliable way, because the stable voltage and constant current of the charge are completed by the line charge, which can avoid the damage of the battery by the high voltage.
The difference between the wired version and the wireless version of Apple airpods 2 is: the charging case indicator light is different. The wired indicator light is inside the charging case and can be seen only when the cover is open, while the wireless charging indicator light is outside the case.Charging method is different. The wired charging case only supports lightning cable charging.
It's not a good idea to keep your phone on a full charge for long periods of time, whether it's using wired or wireless ways to charge your phone. According to experts, while we all know not to overcharge a phone's battery, keeping it at maximum can also cause the phone's battery to drop too quickly.
Straight charge. It can charge fast and play at the same time. Wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. Wireless charging to take off the phone cover; Base heatingIt goes to your phone; Low efficiency of wireless charging; Position deviation and leave the base can not charge; Charging time more than double; Wireless charging power 5W, playing the phone will not charge into, and will not hold the base to play.
Wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, offer wireless charging services where users simply place their phones on the charging mat without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to stay at home and in the car at any timeCharge up.
