The rapid development of consumer electronics in the past few years and the lack of battery life demand, greatly stimulated the development of wireless charging technology, now on the market to support the use of wireless chargers for electronic products has become more and more, so in the end, compared with the traditional wireless chargers and wired chargers, excluding the cable and what is not the same place? Let's take a look at a comparison between wireless and wired charging.
1, charging efficiency: in the case of the same charging time and conditions, wired battery chargers can reach 95% of the power after charging, using the latest technology wireless chargers can only reach 90% of the power. Although the speed of wireless charging has now improved, but obviously in the charging efficiency wired than wireless to be more high-speed and fast, wireless chargers in the charging efficiency there is still a gap in the technology there is room for further improvement.
2, convenience: wireless charger convenience is to get rid of the charging line, just within a certain range can be charged. While the wired charger, the disadvantage is that to charge must be connected to the charging cable, unplug the charging cable can not be charged.
3, physical damage: the use of wireless chargers for electronic products eliminates the problem of interface damage, while allowing the device to reduce the exposure of the charging port, reducing the possibility of dust and liquid immersion. And wired charging with the use of longer time, the data interface has the potential for poor contact.
4, universal: now the development of intelligent products more and more rapidly, using a variety of charging devices more and more, smart watches, cell phones, tablets and so on. These different functions of different models of products basically can not use the same charger for charging. The advantage of wireless charger is that it supports the universality of sharing a wireless charger, it is possible that only 1 wireless charging base at home in the future to meet all appliances, intelligent terminals for charging.
5, cost: wireless charging is the use of electromagnetic wave induction principle for charging equipment, energy coupling through the coil to achieve the transfer of energy. There is a coil at the transmitting and receiving ends, and the coil at the transmitting end is connected to a wired power supply to generate electromagnetic signals, and the coil at the receiving end senses the electromagnetic signals at the transmitting end to generate current to charge the battery. Therefore, the composition and structure are more complex and costly. The wired charger only requires a stable power supply plus the necessary control circuits such as constant current, voltage limit, time limit, etc. The cost is extremely low.
Compared to the traditional wired charging method, wireless charging technology can break the use and space constraints, bringing a lot of convenience to the use of life, with the continuous innovation and improvement of technology, the wireless charger is just around the corner.
