Feature●Input voltage range: 4.5V to 32V (the input voltage must be higher than the output voltage because it is a voltage drop module). Output voltage range: 3V to 12V, automatically set according to the fast charging protocol.●Output power: up to 24W (4V/3.6A, 5V/3.4A, 9V/2.5A, 12V/2A, etc.)●Built-in synchronous circuit step-down converter chip. Input overvoltage protection, input undervoltage protection, input overcurrent protection, output overcurrent protection, output short circuit protection, over-temperature protection.●Fast Charge: Suitable for many popular phones. Application: solar panel for charging mobile phones, car charging system, DIY, driving recorder, power supply DIY, household power supply DIY, etc.●The USB output voltage depends on your device. Different devices have different output voltages. The conventional USB output voltage is 5V. According to the QC protocol, various fast charging voltages can be output. In general, the fast charging voltage of the mobile phone is 9V 12V.Description Package includes:
