1, Huawei 66w fast charge can be used in 40w fast charge mobile phone Wireless charging can not reach fast charge , but the use of power can not reach 66w, the charger can be backward compatible, as long as the charging protocol allows it to be used. Fast charge refers to the wireless charging can not reach the fast charge is a charging side that can make the battery reach or close to the full charge state within 1-2 hoursIt is often used for charging when the battery needs to be restored to the fully charged state in a short period of time.
2, the use of 66w charger to 40w fast charging mobile phone, you can, but need to meet the following two conditions wireless charging can not reach fast charging : 66w charger has 40w power mode mobile phone is the same brand and support fast charging condition one: Not all 66w chargers can charge 40w fast charging phones, because different chargers may have different combinations of output voltage and current.
3. If you are using Huawei's official 66W charger to charge a 40W Huawei mobile phone, please rest assured.
4. It is the same brand of mobile phone and charging head charging line, although it is a 66w charger to charge 40w mobile phone, it is OK, it is a fast charging protocol, still can quickly fill the phone. Generally speaking, there will be some impact on the battery life, after all, the charging current is large Wireless charging can not reach fast charging , the speed is fast wireless charging can not reach fast charging , the conversion efficiency of the system is high. The selection of components such as triode with small internal resistance can greatly improve the efficiency of wireless charging. However, with low internal resistance, the cost will be relatively high. The transmitting end and the receiving end cannot match in time, resulting in loss, which affects the speed of wireless charging. The power output of the transmitting end will be adjusted flexibly according to the receiving end, and too much transmitting power will produce too much power loss when matching with the receiving end.
Charging method Wireless charging can not reach fast charging : The wireless charger must first load the iPhone into the charging protective case, and then put the protective caseIt is placed on the induction base, and then the induction base is connected to the power plug, and the power plug is plugged in. Connect peripherals Wireless charging cannot reach fast charging : iPhone connects peripherals in wireless charging mode, one is to take out the iPhone loaded into the charging protection case, the second is to connect Mini USB, and finally Mini USB connects to the peripherals.
GND is ground. The common negative electrode. This stuff improves efficiency. One, coil material. With two-wire structure, the effective conductive area decreases due to the skin effect of high frequency conduction. So it can be usedMultistrand (insulated) winding coil. Three use low voltage drop diodes. Fourth, the electromagnetic wave is attenuated by the square of the distance, so the closer the distance, the higher the transmission efficiency.
1, iphone wireless charging is slow, the reasons are as follows: because to take care of the cost, but also pay attention to security. Therefore, after testing and evaluation, it was finally determined that 7:5W is a safe way for the new iPhone to achieve wireless chargingAnd cheap solution, compared to the current support to 15W wireless charging is certainly much slower.
2, battery life will be damaged, but not because of fast charging, as long as the life of the battery has been lost, fast charging and slow charging will lead to this situation.
3, conclusion: For non-iphone 12 model users, MagSafe charger performance is not ideal. Even compared to the 15W wireless charging of the iPhone 12 Pro series, MagSafe is charging older iphones like the iPhone XS MaxThe speed is extremely slow.
4, HUAWEI Wireless charger 15W (Max) wireless fast charger: Because the charger has been on the market for a long time, there will be incompatibility resulting in broken charge, it is recommended to use Huawei Super fast charger (MAX 27W). Tip: If Huawei mobile phone wireless reverse charging: wireless charging coil is difficult to align, it is not recommended. If a third party wireless charging base: there may be incompatibility.
5, if the use of computer USB interface, non-adaptive mobile power or car charger to charge the phone, the charging current of these devices is relativeSmaller, slow charging speed. Please check the charger and data cable if you use a non-standard charger or data cable, the charging may be slow due to charging specifications or compatibility.
6, wireless charging function chicken ribs, I think many people do not use it one of the reasons is because the charging speed is too slow, seriously affecting the efficiency of battery life. In order to improve the charging speed, many manufacturers are creating wireless fast charge technology, the current market is more prominent Huawei Mate 20 series equipped with 15W wireless fast charge. Today, there are rumors that Meizu is also developing 15W wireless fast charge technology, and it is currently under testThe trial phase.
Check whether the phone is overheating, it is recommended to charge in a good heat dissipation environment. Check whether the wireless charger indicator light is on normally, and check whether the connection between the charging base, data cable, charger, and power supply is in poor contact. It is recommended to reinsert the wireless charger. Verify that the center of the phone is placed in the center of the wireless charging base during charging, and remove other items (such as bus passes, metals, etc.) between the device and the wireless charger.
For wireless charging can not reach fast charging to ensure that your sleep environment is quiet, will automatically enter the silent charging state, the fan speed will be reduced. During this time, the phone/charging pad intelligently adjusts the wireless charging power, and the charging speed is slower than the rest of the day. Huawei this 50w fast charge after 9 o 'clock automatic slow down silent charging, after 7 o 'clock in the morning the speed is normal, before I thought it was bad, who knows there are such rules, mainly can not close this restriction is the most uncomfortable.
It is recommended to try after reinserting the charger and data cable, ifThe data cable is not plugged in place or the insertion speed is too slow, which may be identified as a normal charging mode. It is recommended to use the standard charger and data cable attached with the Honor device, and the charger and data cable will be tested when charging, and the following conditions can be met to enter the super fast charge mode Wireless charging cannot reach the fast charge : ① : The device and the charger support the super fast charge, and the charging mode is the same.
At this time should pay attention to whether there is a metal object placed on the wireless charger, please take it off and charge it again. It'll just take a second, it's not in the right place, we got a metal object,Automatic protection Settings. Make sure you use the official charging head. Second, look carefully at the wireless charging instructions, encounter a metal foreign body near, it will automatically cut off wireless charging, and continue to flash the green light, and return to normal after power off.
