How to Charge Laptop Without a Charger

Unlike mobile devices, laptop chargers are exclusive to their devices or brands, making it hard to find a spare charger when you forget to bring yours. Most of these require an AC power outlet, and if you don’t have one, it may seem impossible to charge your device. Fortunately, there are many ways to charge a laptop without a charger. Let’s roll through some simple measures you can take when you don’t have the manufacturer’s charger around.

1. An External Battery Charger

An external battery charger can be a great alternative to charge most laptops with removable batteries. These short-length chargers come with a wall socket plug and a battery dock. While there are a few brand-specific external battery chargers, most of them usually work on all batteries. Here are the steps you need to follow to charge your laptop battery using an external charger.

Step 1- Remove the laptop battery. 

Step 2- Mount the laptop battery on the charging dock and plug the charger into an AC outlet.

Step 3- The LED indicator will let you know when the battery is fully charged. 

2. Universal Charger

Many people prefer a common solution to charge their laptop without a charger- using a universal charger. These chargers have multiple charging pins available in different designs and can charge your device even from 12V DC power sources. Moreover, you can buy these charging pins separately to ensure you have the right charging pin for your laptop. However, you should use these properly since incompatible pins can damage your computer. 

3. Car Battery 

If you spend a lot of your time on-road, grooving to car music, you can do that while charging your laptop. It may seem tricky to wire your laptop directly to the car battery since most laptops come with 8V+ battery voltages, whereas most car batteries have a 12V voltage rating. While hotwiring a car battery directly to your laptop may charge it, you may end up with a dead car battery. 

The most efficient way to charge your laptop using a car battery is through an inverter. You can pick from several DC to AC converters available to generate an AC output of 12V to 24V. An inverter can be utilized through a car’s cigarette lighter, and it can charge your laptop in 3 simple steps:

Step 1- Plug the inverter in the lighter socket.

Step 2- Use your laptop’s AC adapter to charge your laptop through the socket available in the converter. 

4. USB Type-C Charging

If you are among those lucky ones that have laptops with USB Type-C ports on them, charging it should be the least of your worries. USB Type-A ports were only designed for power output & data transfer. Thanks to USB Type-B and now Type-C, they allowed in and outflow of power while also offering faster data transfer rates. 

So if you don’t have your laptop charger on you and there’s a Type-C mobile charger lying around, perhaps you should put it to work. You can also charge a USB C laptop using a power-bank. Another silly but emergency solution can be using your mobile device. With a Type-C to Type-C cable, you can connect your smartphone with the laptop and choose ‘supply power to the connected device’ when prompted. It may give you a very limited time, but it can be a life savior. 

Conclusion 

Here we conclude the best ways to charge your laptop without a charger. The methods described can be great temporary fixes in crisis but charging your laptop without an authentic charger can be bad for the battery life. If you can buy or arrange a new branded charger exclusive to your laptop, go for it before anything else.
