Verizon, the second largest telecom company in the United States, introduced a wireless charger pad that features the popular Type-C input.  The CCG2 CYPD2122 controller enables a wireless power transfer via internal conversion. The wireless charger pad powers up any Qi-compatible devices, including Samsung’s fast charging phones. This is the world’s first certified EPP Qi multi-coil 15W charger.

You can charge your phone horizontally or vertically with his Verizon charger. 

The base has a slight tilt to allow users to see the screen easily when the phone is being charged.

The charger pad comes with a layer of non-slip rubber coating. It’s good that the charger won’t slip, but the coating does attract dust. 

Though the charger is rectangular, the base is circular.

According to the official website, this charger supports Samsung ‘s fast charging devices.

You can see the screws after removing the anti-slip pad.

There are two circuit boards underneath.

There’s a total of eight coil; the upper four coils are responsible for the identification of foreign objects and the lower four coils are responsible for charging.

The back of the circuit is clean and organized with a piece of insulation tape to protect it.

The metal plate under the charging coils is responsible for the ferrite’s protection.

There are four nicely arranged coils to identify any foreign bodies .

Siyin CP-SC2 chip is the core of the wireless charging pad. It’s a single-input power management chip that is specifically designed for wireless charging applications. Through the serial bus, CP-SC2 can communicate with the external MCU to obtain information to drive the battery charging chip. The integrated power tube directly drives the external power switch while the chip has a built-in circuit detection. When over-current or over-voltage is detected, it will automatically turn off the power tube.
