9V 12V 24V to 5V DC-DC Step Down USB Charger Module


9V 12V 24V to 5V DC-DC Step Down Charger Power Module 2 Double Dual USB Output Buck Voltage 3A Car Charge Charging Regulator.



DC-DC USB buck charging module (with work indicator, standard contact gold-plated socket) Compatible with all kind of mobile phones.


  • Product Size: 28 * 32 * 8mm
  • Product weight: 5.5g
  • Input voltage range: 6-26V
  • Output voltage: 5.2V (consider the charge line loss, the output is 5.2V or so, the load side is about 5V)
  • Output current: 3A (in the absence of heat sink device, the stable output current is 2A)
  • Positive and negative can not be reversed, and the input voltage can not exceed 26V, otherwise it will lead to chip damage!
  • When working in power, you can not touch the circuit board on the sampling resistor, IC pin, otherwise it may lead to damage to the output voltage of the device!
