Interpretation of wireless charger

As smart phone has been penetrated into everyone's life such as shopping&social intercourse&work, Smart home with wireless charging, squatting off the line constraints, office, conference room, meeting room, living room, dining room, bedroom, etc. Let your mobile phone put a phone to recharge the phone, let SO EASY! In the future, we will buy smart furniture, go out to eat, travel and stay in hotels without charging and data cables.

The wireless charger sometimes does not respond. The first thing to look at is that the phone model does not support it. You don't need to install a wireless charging coil. Please check the attached picture.

a. Mobile phone built-in wireless charging receiver: you can charge directly on the wireless charger, such as Samsung S6, Nokia Lumia920, Google's Nexus4/5 and so on.

b. The wireless charging receiving end contact is reserved inside the mobile phone: wireless charging receiving coil needs to be installed to achieve wireless charging, such as Samsung's S3/S4/Note2/Note3.

c. The mobile phone itself does not support wireless charging at all, and it is necessary to install a wireless charging receiving back frame for wireless charging, such as Apple's iPhone 5/5s/6/6s.

Secondly, there are LED lights around the wireless chargers of well-known brands. When the mobile phone is charged on the wireless charger, the LED lights around the wireless charger will light up, or some be a tone, showing the status of use. Sometimes it is unresponsive, it takes a few seconds to charge before putting it on, and sometimes it has to be replayed.

Then, please check if the phone is centered on the center of the wireless charging pad. If there is any inclusion between the phone and the wireless charging pad, it may not be charged properly. Check the back cover of the phone again. If you use the protective phone case too Thickness may hinder wireless charging, it is recommended to remove the phone case and recharge the attempt.

Finally, the transmitter power of the wireless charger may also cause wireless charging to be used. The short-circuit current of the receiver output can reach 1A. Actually, it is only about 0.3 when charging. The voltage of the mobile phone is directly reduced to 3.9V. This voltage can not reach the rated voltage for charging the mobile phone, and the maximum operation of the wireless transmitter. The current is only 600ma, and the smart phone needs to be 700ma~800ma or more. Therefore, the wireless charger's transmitting power is too small, which will make the charging charge.

I hope that the above opinions can solve the practical problems for you. Wireless charging is also slowly improving and perfecting. Wireless replaces wired and smashes the constraints of the line, making our life more convenient and convenient.
