The method of use is as follows: After plugging in the power supply, touch the arc light pole with your finger at any position to turn on the light. Put the device that needs to be charged under the lamp, switch the mobile phone to the wireless charging mode, and put it into the wireless charging induction area of the lamp. Use the phone charging cable to connect the lamp USB port to the phone, and the phone can also be charged.
Wireless charging, desktopNever so neat. The touch design is adopted, and the three touch buttons below are the light switch key, the on key and the timed shutdown key in turn. At the same time, this is also the wireless charging area, if your mobile phone supports wireless charging, it can be directly put up to charge the mobile phone, say goodbye to the bondage of the data line, the desktop is suddenly clean. Oh, and you can charge it wirelessly without turning on the lamp.
Very simple, discharge regularly. For example, every month (if there has been no power failure), do not plug in the AC plug, turn on the light, until the light is not bright, indicating that the electricity has been discharged. Plug in the AC power.
This musical lampThen generally can not charge the mobile phone wireless, wireless charging now only the kind of small disc, like your music lamp then it must still need a line connection, no connection then it must be that, well, there is not much of the role, so you still need to pass a certain connection. Technology that uses magnets to charge devices.
2, this is OK, it is the earliest wireless charging CBB capacitor in the industry, belongs to the most mature technology. The biggest advantage of CBB is that it is cheap, and it only costs a few cents. 3, Lei Jun held a public speech on the 10th anniversary of millet, and released the millet 10 supreme commemorative version of the mobile phone, charging, the mobile phone built-in graphene-based butterfly fast charging battery, support 120W wired second charge 50W wireless second charge 10W wireless reverse charging. In addition, a series of hundreds of watts car charging, intelligent tracking wireless charging, vertical wireless charging bank and vertical air-cooled wireless chargingAccessories are also introduced.
The positive and negative electrodes of the in-line electrolytic capacitor can be distinguished by the length of the pin and the color of the housing, and the pin length is positive; Short pin is negative; The gray part of the housing with a small area corresponds to a negative pin and the other end is positive. For encapsulation, the positive terminal is generally indicated by marking ""; Or the negative electrode can be represented by a painted area.
The usual circuit board is marked on or near the two pads of the capacitor-, the actual color on the board is white, that is, the pin on the side of the printed white face is negative. The name of the circuit board is: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board.
First, let's look at the differentiation method of in-line electrolytic capacitors. Its positive and negative poles can be distinguished by the length of the pin and the color of the housing: the longer end of the pin is positive, and the shorter end is negative; The gray area on the housing corresponds to the negative pin,The other end is positive. The package is usually marked with a "" or painted area as an indication. For the chip aluminum electrolytic capacitor, the obtuse part on the base corresponds to the positive electrode, and the straight side part corresponds to the negative electrode.
The circle is divided into two halves, one half is black for negative, and the other half is colorless for positive. The black shadow on the left is the negative terminal, and the right is the positive terminal. The capacitor position on the motherboard, if it is black and white, the black part is negative, and the white part is positive. If it is white or black and colorless, the part that is painted white or black is negative, and the part that is not painted is positive. Under normal circumstances, the range of negative painting part is small.
The biggest advantage of CBB is that it is cheap, and it only costs a few cents.
1, high cost: The charger needs to have a push coil Guangdong cbb wireless charge electronic line Guangdong cbb wireless charge , and the electric device needs to have a power conversion electronic device Guangdong cbb wireless charge , both need to have a coilAnd high-frequency filtering circuits are required to meet electromagnetic compatibility, so the cost is higher than direct charging.
2. This is indeed possible. In the scenario where the customer originally used TDK GRM315C1H104A01L, the market price was confused and the delivery was unstable due to the suspension of TDK production. In view of this situation, Dongguan Keya Electronics newly developed ultra-thin polypropylene film capacitor, which has reliable and stable performance, temperature rise and size adjustment of the circuit board can be placed. After 500 hours of aging test, it can be replaced with confidence after trial verification.
3, wireless charging technology does not use the charging line at all, but the use of magneticA technique for charging devices in a field, inspired by wireless power delivery technology. Magnetic resonance is used to transfer charge in the air between the charger and the device, then the coil and capacitor form a resonance between the charger and the device to achieve efficient transmission.
Unlock recognition function is different non-UD version is the standard version, with 3D face recognition function; And the MATE 20 is ProUD not only to have 3D face recognition,It also has the function of screen fingerprint unlocking, and the memory size of the two is different. The memory size of the MATE 20 ProUD version is 8G, and the memory size of the non-UD version is only 6G, obviously the UD version is larger.
There is no difference in the appearance design, the main difference between the two is the function of the system unlock recognition of the phone, Mate20 Pro unlock is 3D face recognition, the standard version of Mate20 Pro; UD version means the use of under-screen fingerprint recognition unlocking method, on the basis of 3D face recognition also adds under-screen fingerprint unlockWay.
The difference between the two is that the price is different and the unlocking method is different. The PROUD version of Mate20has under-screen fingerprint unlock and face unlock functions, and the ordinary version is rear fingerprint unlock and face unlock. Secondly, in terms of price, the starting price of the ordinary version is 5399 yuan, the starting price of the ud version is 5999 yuan, and the difference between them is 600 yuan, which shows that the ud version is more expensive.
Not recommended to buy ud version. UD version is more than an in-screen fingerprint, the memory is larger than the ordinary version of 2g, the ordinary version is 6gb memory, and the ud version is 8g memory, but the price is expensive600. In terms of cost performance, it's not very good value.
The difference between Huawei Mate20ProUD version and non-UD version is from the three aspects of memory, price and unlock recognition function. First, the difference from the memory Huawei Mate20proUD version uses 8GB memory. The Huawei Mate20pro version uses 6GB memory, which is smaller than the UD version. Second, from the price point of view, Huawei Mate20proUD version is slightly more expensive.
