Is it possible to charge the laptop without a charger?

How can I charge my laptop without a laptop charger?

  1. Use a universal adapter
  2. Battery
  3. Use an external laptop battery charger
  4. USB C charging

Use a universal adapter

It is perhaps the most common solution for your battery problems. These universal chargers come with multiple chargers, so you’ll surely find one that will fit into your laptop’s charging port.

You can also purchase individual charging kits separately. Some universal adapters even have the ability to charge your laptop from a car or other 12V DC power points.

When plugged in, the adapter not only powers the laptop but also charges it. However, if the leads are placed incorrectly, they may cause improper voltage and damage your laptop.

Vehicle battery

If you are someone who spends more time outside than at the office, you can use the car battery to charge your laptop.

As most modern laptops have battery voltages of 8V and higher, it can be difficult to connect the laptop directly with the battery, most car batteries are rated at 12V.

Still, there are ways to “connect” a laptop to a car battery, even if the voltage is less than 12V. However, it is important to be careful during handling with a depleted car battery as it can damage the laptop.

The most efficient way to power or charge a car battery to a laptop is by using an inverter. There are several inverters, and they can generate alternating current from a DC source with an output power of between 12-24V.

Once you have the inverter, you can definitely use your car cigarette lighter to charge your laptop. To do this, follow these 3 simple steps:

Step 1: Connect the inverter directly to the cigarette lighter socket in your vehicle.
Step 2: Now connect the laptop’s AC adapter to the inverter.
Step 3: Connect the AC adapter to the laptop.

Use an external laptop battery charger

It is a standalone device that does not connect to your laptop. Instead, remove the battery from your laptop, insert it into a charger, and then plug it into a power outlet.

Most external laptop chargers have indicator lights that flash while the battery is charging and will remain steady when the battery is fully charged.

P.S. External laptop chargers are usually brand specific, so choose the one that matches your laptop’s specs.

USB C Charging

If you are one of the lucky ones to have USB Type-C on your laptop, you don’t have to worry anymore.

The USB Type-A port only allows data transfer and power output, but not input. With the introduction of USB Type B and most importantly Type C, not only fast data transfer is allowed, but also power input and output.


While the methods outlined above can offer a solution to charge your laptop when you don’t have a charger, keep in mind that it costs and needs to be purchased in advance.

In any case, it is cheaper and safer to buy a laptop charger.
