Many motorists have a need to connect various electrical devices to the on-board network. Among them are a mobile phone charger, vacuum cleaner, TV, laptop. The situation is not difficult if the connected device is designed to be powered from the on-board network. And if the voltage of the device is not designed for the voltage that is available in the car's network? Such a device is a laptop.
Instructions
Step 1
Purchase a special device - an auto adapter for a laptop, which must have a cigarette lighter socket. Please note that the electrical parameters of the laptop power supply and the purchased device must be identical. The operating voltage of your computer ranges from 15 to 24 volts.
Step 2
Remember that the power supply and adapter must always have the same operating voltage, a discrepancy of only one volt is allowed. The device plugs have the same design and connection polarity. The polarity markings of the auto adapter and the laptop must match exactly.
Step 3
There are universal adapters that have an output voltage switch. Here you can ignore the compatibility of the parameters, this is achieved by setting the desired voltage with the switch. These adapters are available in two versions: with an output current of 4.7 amperes for a laptop with a diagonal of 17 inches and with a current of 3.7 amperes for a diagonal of 15 inches.
Step 4
Buy an inverter if you want to make a mobile center out of your car, connecting there also a printer and a scanner. The inverter converts the machine's mains voltage to 220 volts, which is standard. They differ in power, and the more devices are connected, the greater the power of the inverter.
