How to charge a dead laptop without a charger?

1. Use a Power Bank to Charge Your Laptop

You may be able to charge your laptop using one of its USB Type-C ports even if you don’t have the original charger with you, depending on the model. You can use a power bank to charge your laptop in the same way that you would charge your smartphone when there is no other way to charge it.

However, whereas most laptops require 8 to 12 volts of power, most power banks only provide 5 volts, necessitating the purchase of a power bank that supports 12 volts or higher.

Point to be noted:

You must keep in mind that there are early generations of laptops with USB Type-C that don’t support charging from a powerbank.)

2. Use a Car Battery to Charge Your Laptop

If you can’t afford a power bank, another option is to use the battery in your car to charge your laptop. You can power anything that requires up to 300 watts with an inverter like the BESTEK 300W Power Inverter. It may not be enough to run power tools, but it is more than enough to charge your laptop in this case! The disadvantage of this strategy is that you must leave the power inverter somewhere on the vehicle’s floor.

3. Connect with a USB Type-C Adapter

If you don’t have a power bank or can’t charge your phone using your car battery, you can use a USB Type-C adapter instead. USB-C, unlike Type A, has a tiny oval-shaped connector that is optimized for high-power connectivity. It has the ability to conduct more power at considerably higher speeds.

A USB Type-C adapter, such as the Anker USB C Wall Charger, will charge your laptop similarly to a power bank, however, it will require you to plug it into a power source, whereas a power bank is a standalone power source. It is one of the safest methods to charge via USB-C because the adapter contains protection that shuts off charging when it detects high heat or other concerns.

4. Use a universal power adapter to charge your laptop

While it’s fantastic to know that you can charge your laptop battery without using the official charger, if you set the voltage too high when using a universal power adapter, you’ll most likely end up with a dead or failed battery. It usually comes with replaceable tips and is compatible with a variety of brands. Many of the battery packs can be charged using the 12-volt cigarette lighter in your car, making them truly portable.

5. Use a Super Battery to Charge Your Laptop

Super batteries are similar to backup or replacement laptop batteries. They come with different charging cables and are designed to replace your laptop’s original battery. Make sure it fits your laptop and is the proper size when you buy one. These gadgets are brand-specific, so they might not function with your laptop even if it’s made for it.
