How does psp charger charge mobile phone? adapter
Or switch a, PSP plug b and mobile phone plug yourself ~
How else can I buy one or borrow one?
How to make an automatic power-off charger is already available.
I want to make a small generator to charge my mobile phone. You are a genius. This can only be done with professional equipment. . . A generator is impossible. Wouldn't it be more convenient for you to spend more than 100 on Taobao to buy an external power supply? .
Please accept it, thank you!
Is the mobile phone hand charger charging fast? The charging speed depends on the battery. Generally, a good battery charges quickly, and it will be ok in 2-3 hours. Except for the long charging time of large-capacity batteries, other similar batteries will take longer, 7-8 hours, and some even longer.
I haven't seen a manual charger, but there is a problem. The voltage and current required for charging should be stable, and charging for a while and not charging for a while will affect the battery life.
How the charger charges the mobile phone, the correct new charging method and how to charge the mobile phone can better protect the battery;
1. For the first three times, the new battery will be used for low battery alarm, and then the mobile phone will be fully charged with the original factory direct charge, and then it will continue to be charged for about 1 hour.
2. In daily use, the battery is fully charged. To avoid charging for a long time, it is recommended to use an alarm. In case of shutdown, the battery should be charged as soon as possible.
3. Try to avoid charging before going to bed, because it takes a long time to charge before going to bed and the voltage is unstable at night. In many places, the voltage is relatively high at night and fluctuates greatly, which has a great influence on the battery.
4. Mobile phone batteries can be recharged, used or deactivated. Cycle life refers to the number of times of complete charge and complete discharge, and partial charge and discharge can be understood as a fraction of life. The key to battery use: the battery can be charged for 20 minutes to half an hour to reach saturation after it is fully charged, but it must be avoided to charge for a long time after it is fully charged.
We should also pay attention to the following points:
1. The mobile phone or charger of lithium battery will automatically stop charging after the battery is fully charged, and there is no so-called "trickle charging" in which the nickel charger lasts for 10 hour. In other words, if your lithium battery is fully charged, it is also charged in vain on the charger. None of us can guarantee that the characteristics of the battery's charge and discharge protection circuit will never change and the quality will be foolproof, so your battery will be on the verge of danger for a long time. This is another reason why we oppose long-term charging.
2. In addition, for some mobile phones, if the charger is not unplugged after charging for a certain period of time, the system will not only stop charging, but also start discharging-charging cycle. Perhaps the manufacturer's practice has its own purpose, but it is obviously unfavorable to the life of batteries and mobile phones/chargers. At the same time, it takes a long time to charge, often at night, but according to the situation of China power grid, the voltage in many places is relatively high at night and fluctuates greatly. As mentioned earlier, lithium batteries are very expensive, and their ability to withstand charging and discharging fluctuations is much worse than that of nickel batteries, which brings additional dangers.
3. In addition, another aspect that can't be ignored is that lithium batteries are not suitable for overdischarge, and overdischarge is also unfavorable to lithium batteries.
Direct current is needed to charge the mobile phone battery;
Therefore, the power supply connected to various chargers is generally 220V AC, which is converted into DC output through an internal rectifier. The voltage is generally 5V output (except in special cases), and the current depends on whether it is slow charging or fast charging, where the slow charging is 1A and the fast charging is greater than 2A current. In this way, direct current energy can be continuously input into the battery, and the electric energy is increased.
How to charge a mobile phone without a charger 1 Buy a socket without a charger.
2. Use wireless charger (supported by mobile phone)
Borrow charger
4. Use the u *** converter to charge another mobile phone.
Find an electrician and connect the charging cable with a working plug.
What are the disadvantages of charging a mobile phone with a mobile phone charger and charging treasure? No harm! The only drawback is that the voltage of manual charging is unstable! Charging will be slower than charging treasure! But everything has advantages and disadvantages! Don't worry, the landlord's mobile phone battery is not as fragile as those people say! Landlord! It's all manual typing! Hope to adopt!
