Product features
1.4 independent special charging management IC, can effectively support a variety of mobile phones for the maximum current charging, charging speed is fast, safe and reliable
2.Charging identification IC is compatible with the full range of apple’s android products, and most phones can achieve the fastest charging speed.
3.Support 4 USB for 2A current charging at the same time, large current charging fast, the total output current can reach 8A.
4.Input is protected by MOS reverse connection, which maximizes conversion efficiency and reduces loss.
5.Output with overvoltage protection, to see the effective protection of the phone.
6.8-35v ultra-wide input voltage, 12V 24V cars can be perfectly supported.
7.Synchronous rectification scheme can effectively reduce heat and improve efficiency, and the efficiency can reach up to 96%.
8.Industry-advanced flat wire large current inductance, large current and small heat, high conversion efficiency.
9.4 high quality SMT capacitors, and then increase the capacity of MLCC capacitor, the output ripple is lower, less interference.
10.High quality double-layer gold-plated USB port, the service life is 2 times of ordinary USB.
11.The default delivery is about 5.2v output voltage.

(1) do not overvoltage and overload use, or it will damage the battery and power supply.
(2) the module can only buck voltage but not boost voltage, and cannot supply power to electrical equipment higher than the input voltage.
(3) pay attention to ventilation and heat dissipation when working at high power and full load for a long time, so as to extend the service life of the power supply.
(4) please do not work at full load for a long time. Please leave 20% allowance for continuous work and pay attention to ventilation and heat dissipation
