1, in the Qi standard, there is a fixed frequency voltage regulation mode of work. That is, the fixed operating frequency, according to the dynamic load power requirements, through the voltage regulator unit, to achieve dynamic power output. However, the existing voltage regulator on the market first fixed the operating frequency of the voltage regulator itself, and then adjusted the input duty ratio to achieve the adjustment of the output voltage. The inherent disadvantages of this method are: 1) When the input voltage changes, it will directly affect the output stage.
2, fixed frequency is better. Variable frequency architecture worksThe reason is to adjust the transmission power by changing the operating frequency, which will cause certain interference to the mobile phone circuit in some transmission bands, and the fixed frequency does not appear this problem.
3, the socket contact is poor. Replace the charging position and eliminate the intermittent failure caused by poor socket contact. If conditions permit, replace the standby charger for testing. Or send it to the repair test to check whether there is a foreign body in the mobile phone charging interface, such as liquid intake and debris, resulting in poor contact between the mobile phone charging interface and the charger.
The back of the device features product parameters and a useful USB-C interface, and the top is equipped with a power key, SIM card slot and USB output port, so that operation is at your fingertips. Disassemble the WF2-2, the internal structure is fine, the screw is fixed the PCB board, and the double antenna is equipped to ensure the signal stability. The cell part, 8000mAh/8V battery capacity, with thermistor to monitor the temperature, to provide protection for lasting use, while the pole protection design ensures safety.
In TCL official after-sales service center. TCL generally refers to TCL TechnologyGroup Co., LTD. TCL Technology Group Co., Ltd. was founded in 1982, headquartered in Huizhou, Guangdong Province, the main business is semiconductors, electronic products and communication equipment, new photoelectric, liquid crystal display devices, goods or technology import and export, registered capital: 1352848719 million yuan. tclbcd-170wf2 freezer drawer can be bought at TCL official after-sales service center.
The main difference between the two sets of configuration is the graphics card, the two graphics card 270x is better than 660, but the N card has a faith bonus. In addition, I would like to say something that the other respondents did not mention, which is from Wireless charging QI protocol demodulation circuit Your screenshot, a bit like Taobao shop assembly machine, Taobao assembly machine depth, it is recommended that wireless charging QI protocol demodulation circuit you confirm and then buy, the specific can not be opened up, anyway, the novice to buy too many assembly pits, There are more assembly pits online, so be careful.
The preparation before the router (if you are clear about your own connection, you can skip to point 2) the first thing to confirm is what is your "broadband access method"? Of course,The easiest way is to give your ISP (Internet service provider) a call to consult the wireless charging QI protocol demodulation circuit ; You can also make a quick judgment by looking at the network connection you had before you bought the router.
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.
Very simple, discharge regularly. Like, every timeMonths (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.
Wireless charging, the desktop has never been so tidy. 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.
If you don't bring it, you can't use it
