There is a touch switch on the upper left side.
There is also a touch switch on the lower left side.
There are three buttons on the top: parking space lock, SOS emergency call, parking space unlock. When in distress, press the SOS distress button, and the system will automatically send distress information and locate the emergency contact in real time, which is a personalized safety function design. The small magic clip can be paired with the Jindian smart parking lock. After connection, when the vehicle approaches or drives away, the parking lock will be automatically unlocked or locked.
There is a bottom bracket below.
The base is adjustable and can be stretched freely to fit models of different lengths and sizes.
There is an infrared sensor at the bottom.

The Micro USB input interface is located on the bottom right.
On the left side of the button is a QR code, which records the MAC address and serial number.
The power cord interface type is Micro USB, and the ports are all alloy materials
The wire type is noodle wire, which is not easy to be twisted and knotted.
The line body is black.
After connecting to the power supply, the logo position of the small magic clip panel lights up with blue light.
Drop it into your iPhone XS Max phone and it's ready to charge wirelessly in time.
Touch the side touch buttons with your fingers, and the clamping arms on both sides can be released. Of course, you can also wake up and automatically open the clip arm through the voice command of "little magic clip, open the clip" without touching it.
Once the clip arm is open, the phone can be placed.
When charging the phone, the status indicator strips at the bottom of both sides of the small magic clip will light up.
The status light strip lights up with a long blue light.

Remove the phone and the status light strip goes off.
This product comes with a mobile app, which realizes intelligent voice control through voice command interaction and frees hands. The achievable voice commands include: please sleep, open the clip, open and close the charging, open and close the infrared, open the navigation, open the music, stop the cloud, open and close the parking lock, etc.
2. Dismantling of the smart automatic wireless fast charging mobile phone bracket (M3S)
There are tamper-evident labels on the screws.
Unscrew the screws, disassemble the casing, there are many parts inside, and the cable is used to connect.
In the wireless charging part, the circular circuit board in the lower left corner is the wireless charger circuit board, and the upper middle is the wireless charging coil.
