First cut the USB charging cable into two sections not far from the two ports. Use scissors to separate the tail glue of the two wires into a section to screen and then cut off the green wire with a double bottom line. Use hot glue to attach the magnet to the charger. Wrap the wires in the USB with tinfoil. Then wrap the wires and roll them up with copper wire. The USB cable with the copper wire rolled up is then wrapped in electrical tape.
OpenThe back cover of the smartphone, then take out the wireless charging receiver ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery, which is the most difficult part of the process. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
Two meters is temporarily impossible, personal production needs to consume a lot of power, the loss is also very large, centimeter level can buy their own on Taobao stone modification.
2, because of the realization of long-distance high-power wireless magnetoelectric conversion, so setHigh energy consumption. As the distance and power of wireless charging devices increase, the loss of idle work will be greater. Wireless charging technology equipment itself is the realization of secondary energy conversion, that is, the network voltage down (or directly) into direct current after a higher frequency of switching control AC conversion output.
3, if the use is vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
4, electromagnetic induction, magnetic field resonance, electric field coupling wireless chargingHow to charge your phone. Most of the wireless charging on the market now uses electromagnetic induction, which is a widely used technology. The efficiency of charging is very fast. Many of the original accessories of the electronics factory are using this principle, and now we see that most of the Apple mobile phones on the market have this function.
5, the core principle of wireless charging is to use electromagnetic induction, through the magnetic field generated by the wireless charger, to achieve mobile phone charging without physical contact. Wireless charging technology was tried as early as the end of the 19th century, but it failed to gain popularity at the time. That is, until a team of researchers at the Massachusetts Institute of Technology succeeded in developing a phoneMobile phone wireless charging because there is no need to frequently plug and unplug the charging cable, the data interface wear of the mobile phone will be reduced a lot. At the same time, the coil of wireless charging of the mobile phone is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. The wired charging is often inserted and removed easily lead to wear, and the interface is exposed, which is easy to oxidation corrosion. Although wireless charging has many advantages, it is also found that there are many disadvantages in the actual use process.
3, advantages: non-contact, no wire, mobile. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Charging speedSlow: Due to low efficiency, the charging speed is slow at the same input power.
4, convenience: wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place the phone on the charging dock, without plugging or unplugging the charging cable, to start charging. This makes the charging process easier and faster. Flexibility: Wireless charging eliminates the need for a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging.
5, disadvantage: charging efficiency: compared with wired charging, wireless charging efficiency is lower, chargingLonger, which can lead to increased user wait times. Charging distance limit: Wireless charging requires a certain distance between the phone and the charger, if the distance is too far or there are obstacles, the charging effect may be affected.
Do not use the mobile phone when charging. The mobile phone does not need to consume all the power when charging, and can be charged when the machine indicates that the power is low or the remaining power is insufficient.
The S7 Edge has a built-in wireless charging coilYou need to purchase a wireless charger separately to achieve wireless charging. Wireless charging method: Put the center of the back of the phone in the center of the wireless charger, you can check the remaining charging time on the screen. Once fully charged, separate the phone from the wireless charger. Note: When there are inclusions between the mobile phone and the wireless charging board, it may not be able to charge normally.
The S7 Edge supports wireless charging and requires a separate wireless charging dock. If you need to buy Samsung mobile phone accessories (batteries, headphones, smart cases, chargers, etc.), you can do so through the following ways: Samsung Online Store: Go to Samsung online store - Accessories to buyBuy. Samsung mobile phone original accessories mall: pay attention to the "Samsung Service" wechat public account, in the wechat chat interface - Products and activities - Accessories mall Samsung stores around.
