How to make a simple charger for mobile phones

The phone charger is out of battery, teach you two tricks how to make your own mobile phone charger.

It's something that's not practical, not to mention it's not expensive enough, and don't overestimate your hands-on ability, even if someone knows how to do it.

1. Prepare tape, scissors, aluminum foil, cotton swabs, tin foil, and ballpoint pen in advance.

2. Prepare an idle pen, a piece of tin foil in the cigarette box, a knife, adhesive tape, a larger cotton swab, an aluminum foil or a piece of tin foil for the oven, and take out the refill of the ballpoint pen.

3. Cut off the cotton swab, stuff the cotton swab into the pen head, leave the cotton swab head outside, and tighten the pen head.

4. Wrap the tin foil on the pen head, tighten the tin foil, keep the pen tip flat, wrap the aluminum foil on the pen barrel, wrap it gently, don't use too much force, because the aluminum foil is easy to break, you can give it a little force after wrapping it to make it tighter.

5. Wrap the wrapped cigarette box tin foil with adhesive tape, the reason why the pen barrel uses the aluminum foil for the oven is because it can conduct human body current, and it is relatively strong and wear-resistant.

6. Fix it with tape.

7. Wrap the pen barrel tightly with aluminum foil.

8. Wrap the joint with tape.

A well-protected charging cable can basically last for a long time. But there are also many people who use a lot of money for the charger, and they have to change the charging cable almost every two months.

At this time, there will be a bunch of charging heads accumulated at home, but don't worry, the plug of the charger, in addition to charging, has many wonderful uses, let's take a look at what are the uses.

Store the headphone cable.

The headphone cable is always entangled and can't be opened? The plug of the charger can come in handy. As a small object to store the headphone cable, it is still very practical. I did not only waste recycling, but also the storage of the earphone cable.

Phone holder. The plugs of the charger are also varied, in addition to the common two-plug, there are also three plugs. If you have a three-plug charger at home, you can completely reuse it.

Two side-by-side three-plug chargers can be used as mobile phone holders, which is not only simple and convenient, but also extremely stable.

Of course, a two-plug charger can also be used as a mobile phone holder. All you need is a plug, and you can watch movies easily and conveniently.

Disadvantages of charger mixing.

If you're using a low-power charger to charge a phone that needs a high current charge, then the charger needs to be working at full capacity at all times.

1. If a high-current charger charges a low-current mobile phone, the result will hardly have an impact, and the charging speed will not be accelerated.

2. Small current can charge high-current mobile phones, but the speed is slow, and the charger will also be in the load state for a long time, causing the charger to overheat, which is easy to cause the aging speed of the charger to accelerate, so it is not recommended to use it.

3. Not only is the charging speed slow, but the charger will also heat up significantly, and the internal components may be burned out after a long time, so it is not worth it.

Therefore, for the sake of insurance, you should develop a good habit of using the corresponding charger, and do not buy cheap chargers and data cables on the roadside.

Summary. That's right, plugging in the small head is to charge the power bank.

How to charge the mobile phone charger.

Find the charging head corresponding to your mobile phone, there are three common ones, Apple is a separate Apple model charging cable, and some mobile phones are Android charging cable heads, but now the general mobile phone is called a type-c charging cable head.

That's it, right?

How? I don't see what you posted here**.

Oooh oh. Take a picture of your interface and show me.

That's right, plugging in the small head is to charge the power bank.

Ok thanks.

Your charging cable is the charging head called Type-C.

Precautions for charging and battery use: 1Please use the official standard charger to charge the battery.

2.Theoretically, keeping the battery level in the middle range (such as 30%-80%) is more conducive to prolonging the battery life, therefore: (1) If the phone is idle for a long time, it is recommended to turn off the device and charge it regularly to maintain about 50% of the charge.

If the device is turned off at 50% charge and is not used or charged for a long time, the battery may be damaged, resulting in abnormal charging or failure to charge. (2) After the phone is fully charged, it is recommended that you unplug the charger to avoid charging for a long time or being in a high power state for a long time to accelerate the aging of the battery, so as to prolong the battery life. 3.

If the temperature is too high or too low, it will affect the battery life of the mobile phone, therefore: (1) It is recommended that you try to avoid charging and using it for a long time, especially in high-power operation scenarios (such as watching, playing large games, etc.), at this time, the heating of the mobile phone will intensify, and charging and discharging for a long time at high temperature will accelerate the aging of the battery. (2) Please try to avoid using your mobile phone in an environment with low temperature, high temperature or large temperature difference.

Buy a wire charge for more than 10 yuan, why make your own!

There is no practical point in this kind of production. Buying components and making circuit boards, not to mention the effort, is much higher than buying finished products, and it is very difficult to make high-frequency transformers for switching power supplies.

If you can't find the original model, you can buy the same socket (most of the mobile phone power sockets of the same brand are common) other models, as long as the output voltage is the same, because the mobile phone has a fairly complete charging detection circuit inside.

Find a 12 to 15 volt transformer, the current is best around 3A, and then find four rectifier diodes of the same model (there are in the mobile phone charger or universal charger) Find a bad charger and take it off, as shown in the picture of the rectifier diode, through the full-wave rectification to get about 13 volts of DC. It can be used for charging, and the charging efficiency is higher after full-wave rectification, and the harm to the battery is small. It's much easier to understand a little bit of electronics, and if you don't even know the rectifier diode, it's also difficult to make, and this is the production method.

If you are too lazy to do it, you should buy a ready-made one, thirty or forty yuan.

Most chargers are rectified with full wave. Even what the market buys is also full-wave rectification.

Upstairs said to buy a 30-volt pressure buyer, do you know how much it is, it's better to buy a charger directly! Also, you don't even know which is better, half-wave rectification or full-wave rectification, open your textbook first!

Quite simply, do you know how to do electronics? I'll tell you to put it, the simplest and most practical way, you buy a transformer with an output voltage of 30V (current 6A), output a 10A current rectifier diode in series, and you can charge it through half-wave rectification, enough time to remove the loss time, a total of about 16 hours, sufficient voltage Safe and effective, try, upstairs friend, 12V full-bridge rectification only, it should be a 15V transformer, I have to be half-wave rectification, yours is full-wave rectification, which effect is good.
