How to use the McDonald's wireless charger: find the port suitable for the mobile phone model and plug it into the mobile phone charging port; Each table has a circular area with lots of "vinyl" records. Place the mobile phone with the round plastic sheet in the "black film" area of the table. Wireless charging technology (Wirelesschargingtechnology; Wirelesschargetechnology, derived from wirelessPower transmission technology.
ikisspower. According to the notice issued by McDonald's official: as of March 2023, McDonald's wireless charging brand is ikisspower, customers do not need any cable connection, just place the phone in the charging area to start charging the phone. McDonald's is a large multinational restaurant chain in the world, with revenue of 23.8 billion US dollars in 2022. Founded in 1955 in Chicago, the United States, McDonald's has about 30,000 branches in the world. They mainly sell hamburgers.
It uses electromagnetic fields to transmit energy and convert electrical energyThe magnetic field is used as the carrier, and the magnetic field resonance of 78Mhz is used to achieve the effect of air separation charging. Mobile phone products, the general spacing distance is about 50mm. Compared with QI's magnetic induction technology, the charging distance is increased by 10 times.
This technology can achieve penetration of wood, stone, glass and other common materials, charging distance of up to 50mm, so that the transmitter can be hidden under the table, such as any hidden area, so as to keep the desktop clean. In actual use, the micro goose under the table version of wireless charger in the long table thickness of about 45mm environment, the middle part of the area is relatively thin, after testing about 25mm, it can still beIt works, and it charges perfectly.
At this time, the power will be converted from the transmission end to the receiving end, resulting in energy conversion, which is now the most common way of wireless charging. The second is magnetic resonance, which is also combined by a transmitting device and a receiving device. A frequency between the two devices needs to be tuned to the same stage, because only then can they resonate. But there is no way to commercialize this technology.
Reliable. Wegoose technology wireless charging is reliable, the reasons are as follows: strong compatibility: Wegoose technology wireless chargingWith the wipo technology independently developed by Wegoose Technology, and compatible with the wireless charging of the qi standard, the mainstream mobile phones supporting the qi wireless charging standard on the market can be used. Easy and quick charging: Wegoose technology wireless charging does not need to plug and unplug the charging cable, freely put the charging board, easy to pick up when using, convenient and fast.
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. By solar cellHousehold 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.
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 be 800--1200mA.
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 charging method is simple and easy to use, and is 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.
Desk heating pad 220V: 220V refers to the input voltage, that is, the alternating current of the home 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 safety voltage, so the human body contact with the heating pad will not hurt the desk heating pad 220V: 220V refers to the alternating current of the home, once the leakage is harmful to the human body.
