Protection Functions & Applications

Tips: Why a 300W power inverter connected to a car cigarette lighter can’t get a desktop computer start up?

It is not recommended that you take power from the cigarette lighter to charge more than 120W electrical appliances. The cigarette lighter can only withstand about 10A current and about 100W power, because there is about 2-meter wire connected the battery to cigarette lighter, and the negative polarity of battery is connected to the car shell, causing too much loss of voltage and current. The inverter will not start up when it detects that there is no enough voltage and current to maintain its work. The inverter's best operating voltage is 11-13V.

Possible solutions:
1. Change thicker wires from the positive and negative polarity of battery to the cigarette lighter.
2. Connect the original battery connection clip line of the inverter to the positive and negative poles of the car battery, thus electrical appliances within 300W can be started.
