9V / 12V / 24V To 5V 3A DC-DC Car Charging Dual USB Output Buck Regulator Charging Module

1. Input voltage range: 6-24V
2. Output voltage: 5.2V (Considering the charging line loss, the output terminal is 5.3-5.4V, and the load terminal is 5.1-5.2V)
3. Output current: 3A (in the case of no heat sink, the stable output current is 2A)
4. DC-DC USB step-down charging module with working indicator, standard contact gold-plated socket, reliable quality, wear-resistant and durable
5. Compatible cell phone models: for Android series, iPhone series, Huawei, Xiaomi, Nokia
6. Product weight: about 6.2 g
7. Product size: about 33 x 33 x 8 mm

Precautions:
1. The input voltage can not exceed 24V, otherwise it will lead to chip damage
2. The positive and negative poles of the input must not be reversed, otherwise the chip will be damaged
3. When powering on, do not touched on the resistors, capacitors, IC feet on the circuit board with your hands, otherwise it may lead to sudden change of output voltage and damage to the device
