In the use of wireless charging do wireless charging , and generally only charge one device at the same time. In the latest concept of the self-wireless charging field, wireless charging devices can be charged in this area no matter where they are located, and up to forty devices can be charged at a time. However, due to the high cost and level of this technology, it has not been widely used.
In the world, many credit card points are exchanged, and the nature of mobile telecom points exchange on the street is the same, the main purpose is to strong> Do wireless charging earn a middle difference, or accumulate customers for other purposes! First, credit card points, now credit card consumption are points, generally consumption 1 from the wireless charge : 1 points, that is, consumption 1 yuan to a point, there are 16:1 points, there are 1:3, 1:10 consumption points.
NO.1 Wireless charging Low charging power, slow efficiency, mobile phone heating is the first electric car friends on the wireless charging configuration of the most fun. None beforeLine charging is a very fresh concept, when millet wireless charging was just launched, the author also deliberately bought a taste, but did not expect the phone to be put on for 3 hours were not full, and later it was shelved.
In fact, there is no need to use the current technology to put the previous words, probably in a few years or zero years when there is that kind of solar charging mobile phone. However, it was a functional machine at that time, and the words from wireless charging I remember the most impressive one of the advertisements is Changhong's little King Kong never charge. There is light, there is electricity, and then there are candles can also charge, the specific number of mobile phonesI forgot about the money. It was like a thousand or two.
South Carolina OE CC is the most recommended one of the more than ten open headphones I have used, excellent sound quality brings a full range of hearing, not only excellent sound quality, comfort, battery life, connection, etc. is beyond the average level, cost-effective, can be called the best one below 1,000 yuan. As a brand known for open audio, South Carolina has always treated every product with a hardcore technology stream.
German LAMY Star series pen ￥180 Star series pen for boys who need to write or sign frequently, founded in 1930, a new designProcess technology. Perfect design with strict quality requirements, not to mention appearance level. For boys who need to draw pictures, you can also consider two ways to use ink, one can use filling ink, and you can use disposable pen refill.
Can yes yes. Over a small distance (0.1 to 2 cm) the magnet needs to move him around. Wrap a coil around the magnet block. Well, it's just a generator. Make wireless charge I have a circuit you seeSee. It can be done. The farthest (distance) is 4 cm. It's very inefficient. However, you can bring 10 LED highlights in close range. Turn left | turn right. You can also go to Baidu ZVS.
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.
Now the wireless charging is more common magnetic resonance charging mode. The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electricity generated magnetic, magnetic generated electricity! The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is why this wireless charging device often carries a thick base and a "phone case".
Self-made wireless charger 1: External module installation steps Attach the module to the MicroUSB interface for comparisonPlace. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
First, understand how wireless charging works. The wireless charging system mainly consists of two parts: the transmitter (usually placed on the charging pad or charging dock) and the receiver (installed inside the phone). The transmitter generates a magnetic field, and the receiver induces itThe magnetic field is converted into electricity, which charges the phone's battery. To add wireless charging to a regular phone, the most critical thing is to install a wireless charging receiver.
You can buy a wireless charging receiver, stick it on the back of the mobile phone or insert it into the mobile phone charging port, the advantage of this method is that the cost is low, there is no need to replace the mobile phone or dismantle the internal phone, the disadvantage is that it may affect the beauty and feel of the mobile phone, as well as increase the wear and tear of the charging port.
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 againCut out the green line 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.
The fifth step, the processing of the back cover, first find a thin circuit board, cut off the excess part, carve out the positive and negative two sides, weld the spring contact, I use the small contact sent by the seller, but also homemade small shrapnel, a lot of circuit boards have, shrapnel is relatively space-saving. Weld the output line of the wireless receiving patch to the contact circuit board, (pay attention to the positive and negative poles) and then use twoh2>
1, self-made wireless charger 1: External module installation steps Attach the module to the place where the MicroUSB interface is compared. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
2, to add the wireless charging function to the ordinary mobile phone, the most critical is to install a wireless charging receiver.This process usually involves opening the case of the phone, finding where the battery or battery is connected, and welding or connecting the receiver to the appropriate circuit. This requires a certain amount of electronic knowledge and fine manual skills, because the components inside the phone are very small and fragile.
3, the self-made mobile phone wireless charging method is as follows: Prepare materials: The mobile phone charger 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 USB cable in tinfoilLive. Then wrap the wires and roll them up with copper wire.
To change an ordinary mobile phone to wireless charging, it is usually necessary to use a wireless charging receiver and the corresponding modification tool. Please note, however, that this modification may damage the phone or void the warranty, so it is recommended to proceed only after fully understanding the risks and consequences. Wireless charging technology, which allows users to charge devices without plugging in a cable, has become increasingly popular in recent years. However, not all phones support wireless charging natively.
In summary, the modification did not actually make any circuit changes to the host, but added a lead wire, and did not change the volume shapeTo continue to install the thin battery and other rear cover, you can also install a wireless charging component to the thin battery cover. In order to make the modified phone have more charging compatibility, the MINI USB port is empty, even if you do not bring a charger, you can normally use other.
Click to open the Settings and enter the phone Settings interface. Tap to turn on the battery to enter the battery Settings screen. In the battery Settings screen, we click on Battery Health. In the battery health interface, we can directly turn on the wireless charging switch.
