When you drive, your car battery is charged either by an alternator on a modern car or by a dynamo on an earlier car. Driving it will charge the battery if you jump start it after it has been flat. But if you don’t have a car with a battery, you’ll need to charge it yourself.

First, you will need to make sure that you have enough juice to run the engine for at least a few minutes before you start the car.
If you don’t have any juice, then you won’t be able to start it. Second, if you are using a car that has a built-in battery charger, the charging time will be significantly longer than it would be with a battery that is plugged into a wall outlet.
The reason for this is that the charger needs to be connected to the vehicle’s electrical system, which can take a long time to do so. This is why it’s important to have a charger that can be plugged directly into the power outlet of your vehicle, as opposed to one that requires you to plug it into an outlet in your home.
