Features:
1. This module comes with 4 USB ports, equipped with a power adapter board and 4-way phone charger function, and needs to be used in conjunction with a computer power supply;
2. Multi voltage output, supporting output voltages of 3.3V, 5V, 12V, and -12V respectively;
3. Support multiple fast charging protocols, and pairing with charging cables that support protocols can achieve fast charging;
4. Convenient to use, each set of voltage outputs has a corresponding red LED display;
5. Widely applicable, small devices with USB charging ports can charge or provide power input, such as smart speakers, electric toothbrushes, small desk lamps, and other small devices.

Parameter:
Output voltage range: 3.3V to 12V
Output interface: USB 4 port
Compatibility: Compatible with all 20 pin and 24 pin computer power supplies
Size: 97mm * 85mm
Charging protocol description:
1. Single channel maximum output 24W (theoretical value);
2. Output voltage range: 3.3V to 12V, automatically adjusted according to fast charging protocol（ 4V@3.6A , 5V@3.4A , 9V@2.5A , 12V@2A Etc;
3. Output charging:
Support BC1.2
Supports QC2.0 and QC3.0
Supports MTK PE1.1/PE2.0
Supports fast charging protocol FCP
Supports fast charging protocol SCP
Supports fast charging protocol AFC
Supports fast charging protocol SFCP
4. Explanation of actual situation:
a. Charging mobile phones must support the above protocols to achieve charging;
b. The charging cable must be the original charging cable of the mobile phone to achieve charging or fast charging;
c. Regarding the issue of not reaching the maximum output power, we generally refer to the fast charging mark on the phone as the standard; As for the power, the characteristics of each phone are different, and the output results are naturally different, or the charging power of different brands of phones may also have significant deviations.

Power supply instructions for terminal blocks:

1. The output voltages are 3.3V, 5V, 12V, and -12V respectively (where 12V and -12V can form 24V, but the current is very small)
2.When using each set of voltages, the output current should be controlled within 5A as much as possible (without protection) to avoid heating and burning the circuit;
3. Each set of voltage outputs has a corresponding red LED display.
Attention: This module has a power adapter board and a 4-way phone charger function, which needs to be used in conjunction with a computer power supply!

Application scope:
1. The mobile phone charging part supports fast charging, which depends on the protocol.
2. Smart wristband or watch charging (with factory USB adapter)
3. Tablet and laptop charging (devices with L interface and USB Type-C interface are required)
4. Wireless earphones or wireless earphone charging (wireless charging cannot be used)
5. Power bank charging (it is best to choose genuine power banks, not miscellaneous brands)
6. It can also be used to charge many small devices with USB charging ports or provide power input, commonly used for small devices such as smart speakers, electric toothbrushes, and small desk lamps!
