Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
3, add a coat to the phone, and then put it on the launch board can be charged. And then there's the battery replacement.
4. OPPO Finder designs a case that combines a leather case with a battery. This case can achieve several functions: protection, battery, wireless charging. When the protective case is placed on the phone, an electric shock makes contact with the three contacts on the phone to provide power. Probably so, there is anything you don't understand, please ask oh.
1, w charge slowly. 10W charging refers to the charger output power of 10W, that is, 5V2A voltage and current output. 10 watts of wireless charging is still relatively slow, an hour is estimated to be able to charge about 60% of the electricity, basically in about an hour and a half can be full of mobile phone batteries. In the case of the iPhone, the official charging time is five hours on a full charge. If you use a 10W charger, the full charge time will be slightly shortened.
2, wireless charger iPhone8 full about 3-4 hours. Because of iPhone8 series mobile phone wireless charger power is only 5W, that is, only support 5V / 1A wireless charging specifications. Relatively speaking, wireless charging to the iPhone 8 series of mobile phones is a little slow, but the iPhone 8 Plus 2675mAh battery capacity, full charge time and iPhone 8, are the same, more than 3 hours.
3, low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging is often resonant (most electric vehicle charging)In this way) energy is transmitted by the power supply device (charger) to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
4, then power on the wireless charger, please make sure that there is no magnetic object around before connecting the power. Then place it in a flat place to prevent the phone from slipping off it.
1, Zikko Apple wireless charger compared to the common wireless charger on the market, it has a high 10W fastCharging, multi-coil no need to align the fixed position, all-round charging and other advantages. Equipped with high 10W dual coil wireless transmission power, compared to the common single coil, it does not need to be aligned to a fixed position when charging. It has three modes of horizontal and vertical placement, no matter it is horizontal, horizontal and vertical placement, it can truly achieve all-round charging.
2, HUAWEI: reliable quality, moderate price, support a variety of equipment charging, speed is not fast charge, but wireless convenient, suitable for summer use. BELKIN: Stylish design, responsive, fine workmanship, support for fast charging, andThere is non-slip protection. PISEN: high appearance level, light and portable, C port design is easy to use, and has good support for Samsung mobile phone wireless fast charging.
3, next, we recommend the top ten car charger brands for you, including Philips, Huawei, Pinsheng, millet, UGREEN, BASEUS, Newmine, SAST, BULL and BOSCH. Each brand has its own unique features and advantages, and consumers can choose according to their individual needs and vehicle models.
4, as a professional manufacturer of chargers, its wireless charger has efficient and stable charging performance, can quickly charge the device, but also has good compatibility, suitable for a variety of devices supporting wireless charging technology.
5, if you are using nut R1, this wireless charger is very good. Wireless charger recommendation three: Huawei Mate RS Huawei Mate RS Wireless charger When it comes to wireless charger which is good, how can it be less Huawei this major domestic brand, this wireless charger from Huawei is actually Porsche design, can itSupport up to 10W output, using a round and normal design of silicone on top and metal under the appropriate thickness.
Wireless charging power depends on two aspects, namely distance and efficiency. The distance affects the power of wireless charging, the closer the distance, the higher the power of charging, and the farther the distance, the power decreases. Efficiency also determines the power of wireless charging. Efficient wireless charging can be comparable to wired charging, while inefficient charging cannot meet the needs of users. Therefore, efficient wireless charging technologies will promote the success of the market, while inefficient ones will notIt will be.
The current mainstream wireless charging power standard is 10W, which corresponds to the 5V2A charging specification. The wireless charging power supported by Apple phones is also generally in line with this standard. Some devices may support lower power, such as 5V5A, corresponding to a 5W charge rate. In contrast, the power of wired charging is usually around 18W, and the speed of wireless charging is indeed slower.
Try to choose more than 10W power: with the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, the future software system upgrade can also be used.It is recommended that when purchasing wireless charging equipment, try to choose a wireless charger with a power of more than 10W.
This charge is not possible for 500 watts. Generally speaking, the power of wireless charging is relatively low, the power is usually between 5 watts and 15 watts, if the power of wireless charging is increased to 500 watts, it will produce high electromagnetic radiation, which will have adverse effects on human health. At the same time, it will also produce high heat, causing fire and other safety hazards.
