Wireless charging is subject to the development of technology, and the charging efficiency is still relatively poor, because the power of wireless charging itself is small, and the actual performance is not stable.
Disadvantages of wireless charger: bound: wireless charging needs to be adsorbed on the charging base, can not be moved at will, and the user is more bound than wired charging. High price: The principle of wireless charging is different, resulting in the cost of wireless chargers is usually higher than that of wired chargers.
Disadvantages: The charging speed is relatively slow. In the era of fast mobile phone charging, wireless charging is very slow. Now most wireless charging only support 5W charging, slightlyThe slightly faster one is only 5W. And wireless charging really can not meet our needs. Mobile phone wireless charging has the advantages of convenience, flexibility and protection interface, but it also has the disadvantages of low charging efficiency, slow charging speed and high cost. The principle of wireless charging is to use electromagnetic induction to transmit electrical energy from the transmitter to the receiver, which contains a transmitter and a receiver. The transmitter converts electrical energy into radio waves, which are then transmitted to the receiver via an electromagnetic field.
1, the car air pump cable is better. Higher safety: Wired vehicle inflators are safer to place in the car at high temperatures. Wireless built-in car inflators are exposed to high temperatures for a long time, which leads to safety hazards. Faster charging speed: The wired car air pump is charged by connecting the power cord of the vehicle, and the charging speed is faster. Compared with the wireless vehicle air pump, the charging speed is slow through wireless charging.
2, wireless good. Portability: Wireless car inflators do not require power cord and socket support, can be directly placed on the vehicle for chargingThis has better portability, while the wired car air pump needs to be connected to the power supply, which is not convenient.
3, according to safety and practical considerations, it is recommended to use wired vehicle air pump. First of all, the wired air pump is safer and more reliable in the car at high temperatures. Secondly, although the wired pump charges faster, the length of the power cord is limited and may be subject to certain limitations. However, for the normal use of most cars, wired inflators are sufficient to meet the demand.
4. Cable. Stable power supply: the vehicle air pump needs to use the power supply to charge, such as the use of wireless air pump, willIs wire charging better or wired charging better? '> Is wireless charging better or wired charging better? 1, wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, offer wireless charging services where users simply place their phones on the charging mat without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
2, cable charging. In the case of the same charging time, the commonly used cable powerThe pool charger is 93% charged, and the wireless charger is 88% charged. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
3, wireless charging good. In wireless charging, the charger and the charged device do not need direct contact, easy to use, strong environmental adaptability, avoiding the physical interface, so there will be no interface wear, sparks, leakage and other problems, in addition, wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
4, the pursuit of higher portability and comfort, you can choose wireless charging; In pursuit of faster charging speed and wider application range, you can choose wired charging. The advantage of wireless charging is that it provides higher portability, which is especially suitable for wearable devices, smart home and other fields. However, the charging speed of wireless charging is relatively slow, and the distance between the charger and the device will affect the charging effect.
5, today we will talk about the advantages and disadvantages of wireless charging treasure and wired charging treasure, and their applicable scenarios. Advantages and disadvantages of wireless charging treasure: Advantages: Easy to operate: wireless chargingPower is really very convenient, because it uses electromagnetic induction wireless technology, you just need to put the device that supports wireless charging on it, it can automatically charge you, eliminating the tedious plugging steps.
The convenience of wireless fast charging does not bring a significant increase in charging speed, but may be slightly lower than wired fast charging. The power output of the wireless fast charging head to the wireless base is not the final output power of wireless charging, but the input power of the wireless charger. The charging speed of wireless chargers installed on new energy vehicles is limited, which may be due to compatibility issues between external chargers and on-board charging systems.
However, in terms of current technological development, the efficiency of wireless charging is lower than that of wired charging. If wireless charging is used, there is no exposed connector when wireless charging of electric vehicles, completely avoiding safety hazards such as leakage and electricity running. And wireless charging can hide the power supply and transformer underground, so that the car can be charged in the parking lot or on the street special charging points, so wireless charging is very convenient.
NoSimilarly, the wireless charger will have a loss when charging, and the loss is between 30-40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is the result of my own actual testing.
At present, the effective charging distance of wireless charging technology is still limited, and the phone needs to be placed on a device that supports charging. Shortened battery life Wireless charging may lead to accelerated battery wear and shorten battery lifeLife. Slow charging speed Wireless charging speed is relatively slow, temporarily can not be compared with wired charging.
