As we all know, the cigarette lighter is a very important power supply interface on the car, but it is generally a small number of touching. Whether it is a driver or a passenger, there is always a need to use the cigarette lighter and the USB port at the same time, but plugged in the car charge may not have an extra cigarette lighter available, which will lead to a tense situation in the use of the cigarette lighter.
In order to solve the above embarrassing use scenarios and bring convenience to related groups, JOYROOM Jiletang launched a 154W car travel charger JR-CL06, which is a combination of car charging and multi-port car cigarette lighter design products, which can provide 5A1C 6 USB interfaces and three cigarette lighter sockets, fully meet the simultaneous power needs of drivers and passengers. The following charging head network will disassemble this product in detail to see how it is done.
