A laptop is an important work tool, it often happens that you have to travel to meetings or to places where there is no way to recharge from the network. Moreover, some aspects of work or study sometimes have to be decided directly in the car. Therefore, it is very important to know all the possible methods for restoring laptop battery capacity.

Is it possible to charge a laptop in a car
The question of whether it is possible to charge a laptop in a car can be answered positively, but with some reservations. The charge recovery procedure will only be successfully completed if the process of connecting the device and subsequent charging are carried out according to all the rules.
Using a cigarette lighter charger
For owners of personal cars, the optimal solution for restoring a laptop's charge is to purchase and use special chargerconnected to the cigarette lighter. There are practically no special instructions regarding the use of such a device.
That is, the charger is enough to plug into the cigarette lighter socket, and the output cable to the appropriate port on the computer. The main rule is that the charger fits the connector, as a rule, when purchasing such a device, there will be nozzles for all possible devices in the kit.
As a rule, such charges are mainly produced by the Chinese and bought on aliexpress, so you should check it for build quality, chips, cracks and abrasions. If the storage and transportation conditions are violated, the devices may fail even after a short period of operation.
The acquisition of counterfeit products is also fraught with negative consequences. A fake can not only suddenly fail, but also generate an electric current for a long time, which is not suitable for safely charging a laptop battery.
Charging the laptop with a cigarette lighter lasts about 3 hours. During the restoration of the battery capacity, you can also turn on the laptop, but in this case, the speed of charge recovery will significantly decrease.
Directly from the battery
The laptop can be charged directly from the battery if the laptop’s battery rated voltage is also 12 V. Otherwise, electricity can not be dispensed with. Such devices can be manufactured independently only if there is experience and relevant knowledge.
An inexpensive option for changing the DC voltage is the use of small boards of adjustable DC-DC converters, with which you can easily raise the battery voltage to the required values.
Another method of charging a laptop from a battery is to use a voltage converter. That is, if it is possible to assemble an inverter on its own, the output of which will be an alternating voltage of 220 V, then it is possible to charge the laptop using a conventional network adapter without any restrictions.
This is an extremely dubious method and it is not recommended to use it, since it will be very difficult to submit the correct value of the current strength (A) and voltage (V).
Alternative methods
Branded cigarette lighter chargers can cost quite a lot of money, so many motorists think about using alternative methods of charging a laptop. For example, you can buy Power Bank for a laptop, normal for a smartphone will not work. The main thing is not to forget to recharge the external battery.
You can purchase Power Bank for a laptop and for it charging from the cigarette lighter.Using this charge, you can slowly restore the charge in an external battery in a few hours.
Some Power Banks are equipped with solar panels, so when using light-powered energy, you can completely do without car charges. Such models are especially convenient when traveling to nature, because prolonged use of the battery while the car is parked can lead to its complete discharge, and solar energy can be received free of charge all day without any restrictions.
A 220 V car inverter is also not a cheap product, but if such a device was purchased earlier, then there is no need to buy a special adapter for a laptop. The power of the converter will be enough to connect a laptop network adapter to it, if you have the necessary plug for the connector.
