Must-read before buying:

1: The following are the issues regarding the current limiting of the cigarette lighter:

     Since the power of the heater is 150W, please pay attention to the power of the cigarette lighter in the car before purchasing. Some models have a current limiting device in the cigarette lighter, which cannot drive the heater. Specifically, there is no warm air for a long time or the warm air is intermittent. These models cannot use most heaters on the market directly by plugging the cigarette lighter power supply, not because of product problems. If you encounter the above problems, it is recommended to purchase the battery connection line option or go to the auto repair shop to modify the cigarette lighter and use it directly from the battery. (You must start the car to use the heater)

2: Suggestion:  

  Buy [4-meter connection line for current-limited models]

3: For models with insufficient cigarette lighter power, please choose the option with current-limited wires! ! !
