Wireless charging table (Wireless charging table mat)

Today to share the knowledge of the wireless charging table, which will also explain the wireless charging table mat, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!

Principle of a rechargeable table

1, folding table usb interface can be charged. The edge of the desk also has ports that can charge the phone, and the electricity is collected and converted by solar cells on the surface of the desk. Through solar cells, household items can convert the energy in the indirect light source into electricity and store it. The invention of these solar cells means that household items such as mobile phones, lamps and computers can harvest and store energy directly from indirect light, without the need for a wall outlet.

2, the use of 5V power supply through the current limiting IC power supply or the use of power tube controllable power supply, this design is generally seen in the high-end motherboard. Charging through the USB interface of the computer, the maximum current of the computer can only be 500mA, and through the charger (desk USB is also the same), often more than 500mA, many chargers tend to 800-1200mA.

3, this article will give you a detailed analysis of the charging principle of the small lamp. Ac to pulsating DC When charging, the lamp will convert 220V alternating current into pulsating DC to charge the battery. This way of charging is simpleEasy to use, suitable for most small desk lamps. Constant current, constant voltage technology More advanced small desk lamps use constant current, constant voltage technology to ensure that the battery is properly charged. This charging method can better protect the battery and extend the service life of the battery.

4, desk heating pad 220V: 220V refers to the input voltage, that is, the household AC 220V, the desk heating pad charging safety of different desk heating pad 24V: 24V is not only the working voltage of the desk heating pad, but also the safe voltage, so the human body will not harm the heating pad 2201.

2, among them, the socket position on the high-speed rail and bullet train, generally speaking, the second-class seat charging port is at the foot, about a few centimeters from the ground. However, there are also under the back of the seat in front, and the side of your seat can also be looked at. You have to look down. The first class seat charging port is also in front of the armrest. Each business seat has a charging port in front of the armrest.

3, the place where the train is charged is generally at the foot, less than 10 meters from the ground. There are also charging outlets next to the seats, but there are fewer. Charging ports for first and second class seats are also under the seats. Hard sleeper in the aisleThere is a socket under the small table plate, two jacks, one is two, one is three. Therefore, if you need to charge on the train, you can pay attention to the position of the foot and find the specific socket location.

4, is an overnight, long-distance passenger train passengers usually buy a ticket. The hard sleeper is fitted with a bunk on one side. General hard sleeper has upper, middle and lower berth. The bunk is wider than the hard sleeper seat and is covered with a mattress, comforter, pillow and other bedding, as well as a kettle. There are no charging places on the hard sleeper, but the charging places are in the corridor and the conductor's room.

5,Sleeper charging area: There will be sockets under the table, or above the head, or only at either end of the seat in the aisle. Because the seat can be rotated, the charging outlet may be in the front or in the back. The end plug is near the coffee table under the end wall. There are also charging devices on the walls at both ends of each second-class carriage and under the storage area for large luggage, as well as in the bathroom.

Is wireless charging a pseudo demand? Market data Explain everything

is certainly not a pseudo requirement. traditionalThe charging method requires the phone to be connected to the charger, which is very troublesome, especially if the charging cable is wrapped and moped. The use of wireless charging technology only needs to put the phone on the charger, and does not need to deal with any charging line problems, the charging process is more simple and convenient.

The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, to"Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.

The wireless charging technology does not need to be used as a medium through connectors, metal contacts, etc., and can be charged only on the charging seat. Wireless charging does not require a conventional charger and power line, so it can improve the water resistance and reliability of the equipment, no bad connectors occur, and wireless charging equipment has standard specifications, a power supply device can be used for a variety of terminals.

22-year-old student He made hardcore AirDesk, how good is its technology?

1, He did another sensational thing in the technology circle, he created a desk called Air desk, and in the name of the student He | I made a product that Apple gave up...... In the video. After the video was released, He happily mentioned that the top of the hot search list of major platforms, and the video has broken the 9 million mark. The Air desk is actually a high-tech desk made by He, inspired by the Apple Air power wireless charging pad.
