Product Material: Made of PC fire-retardant material, fire-resistant material, and the shell is made of high-gloss shell and oxidation treatment, which is beautiful and not easy to leave scratches. Product Size: 78.0mm*32mm*32mm; net weight is 32g; input parameters are 12V-24V, suitable for cars and suv; output parameters are QC3.0 ports (5V/3.0A, 9V/1.8A, 12V/1.8A ); The total current is 15000mA. Product Features: Smart IC solution, smart shunt, overcharge, automatic power-off protection; Quick Charge 3.0 fast charging technology, backward compatible with QC2.0; for devices to be charged that do not support fast charging, adaptively allocate a larger current to achieve fast charging. Stable Charging: Built-in heavy protection functions such as overcurrent/overheating/short circuit/overvoltage/high temperature to ensure stable current output.
