8V35V to 5V8A power supply step-down module 4-port USB output Android iPhone car charger

Product Features

1.4 independent dedicated charging management IC, which can effectively support various mobile phones for maximum current charging, fast charging speed, safety and reliability.

2. The charging recognition IC is compatible with the entire range of Apple Android products, and the vast majority of phones can achieve the fastest charging speed.

3. Supports simultaneous 2A current charging with 4 USB ports, fast charging with high current, and a total output current of up to 8A.

4. The input adopts MOS transistor reverse protection, which maximizes the conversion efficiency and reduces losses.

5. Output with overvoltage protection to effectively protect the phone.

6.8-35V ultra wide input voltage, both 12V24V and 24V can be supported by cars

7. The synchronous rectification scheme can effectively reduce heat generation and improve efficiency, with a maximum efficiency of 96%.

8. Advanced flat wire high current inductors in the industry, with high current, low heat generation, and high conversion efficiency.

9.4 high-quality surface mount capacitors, combined with increased capacity MLCC capacitors, result in lower output ripple and less interference.

10. High quality double-layer gold-plated USB port, with a lifespan twice that of regular USB.

11. The default shipment is an output voltage of around 5.2V.

Product Matters needing attention

(1) Do not use under overvoltage or overload, as it may damage the battery and power supply.

(2) The module can only reduce voltage but not increase voltage, and cannot supply power to electrical equipment with a voltage higher than the input voltage.

(3) Attention should be paid to ventilation and heat dissipation during long-term high current and high power full load operation to extend the service life of this power supply.

(4) Please do not work at full capacity for a long time. When working continuously, please leave a 20% margin and pay attention to ventilation and heat dissipation
