Methods 3:Utilizing a Car Charger
Using a car charger to charge your laptop battery might be a smart choice if you are ever in a circumstance where you can only access a car and not a laptop or power outlet.

Here is a thorough breakdown of how to operate a car charger:
Compatibility testing: Check whether your laptop can be charged in a car. Make sure your laptop can tolerate this voltage because the majority of automobile chargers have a normal 12-volt DC output. Additionally, determine whether a special connection or adapter is required to connect your laptop to the vehicle charger.
Starting the car: To supply electricity to the car's electrical system and the cigarette lighter or power outlet where you'll put in the car charger, start your car's engine.
Determine the cigarette lighter or power outlet's location by looking in your car's dashboard or center console. It typically has a cigarette symbol or a "power" indicator on the label.

Connect the laptop: Attach the vehicle charger to the laptop's charging port using the proper adapter or cable. Verify the security of the connection.
Watch the charging process: Start your laptop and check how the battery is doing. You could notice a notification or a battery icon on your laptop to let you know it's charging. Watch the battery level to monitor the development.
Safely detach the vehicle charger from your laptop and remove it from the cigarette lighter or power outlet after your laptop's battery is fully charged or when you no longer need to charge it.
Employing an External Battery Charger
To charge laptop batteries without a laptop itself, a gadget called an external battery charger was created. With this technique, you can charge your laptop battery effectively and specifically. 
You may learn how to utilize an external battery charger by following these steps:

Methods 4:DIY Solutions
You can look into do-it-yourself (DIY) options to charge your laptop battery if you're without a laptop or specialized charging equipment. These solutions can offer temporary charging choices in emergencies or special circumstances, albeit they might not be as dependable or effective as specialized techniques. 
Here are a few do-it-yourself suggestions:

Methods 5:Solar Energy
You may use a solar panel to recharge your laptop battery if you have access to sunshine. Get a solar panel that can generate the right voltage and current for your laptop. 
Connect a charge controller to the solar panel and then the charge controller to the laptop battery. 

Methods 6:DC Power Source
A direct current (DC) power source can be used to recharge some laptops. It might be possible to connect your laptop battery to a DC power source, such as a vehicle battery or a portable generator, using the proper connections or adapters. 
To prevent damage, double-check that the power source's voltage and polarity meet the needs of your laptop.
External USB Battery
USB battery packs, which are frequently used to recharge mobile devices like smartphones and tablets, can occasionally offer a little amount of power to recharge laptops. 
A USB charging connection or converter must be used to link the USB battery pack to your laptop. Remember that USB battery packs cannot offer enough power to fully or quickly charge the laptop.
Friends or Public Charging
If you don't have access to any charging equipment, think about contacting friends, relatives, or local businesses, including cafés or libraries, to see if you can borrow or use their charging equipment. Public spaces frequently provide plugs or charging stations that you may use momentarily.
