Discover the six easy ways to charge your laptop without a charger in this post. You could possibly discover the ideal, long-lasting answer to your dead battery problem!


Without a charger, here are 6 ways to charge a laptop:

With the aid of these methods, you can recharge your laptop without a power supply. Try starting your laptop with one of the following six choices if your charger or charging port isn’t an option:

Find Spare Battery:

Although it appears straightforward, not many individuals use this tip, an industry secret.

 Manufacturers of laptops frequently sell batteries as a replacement part. By purchasing a second battery, you can simply keep your laptop operating if you’re travelling and don’t have access to a power source.

 Invest in an external battery charger if you’re unsure how to charge a laptop battery without a laptop charging connector. This device is hooked into the outlet right away.

 Charge your primary battery with your laptop charger and your backup battery with an external battery charger as a practical method to get ready for extended journeys.

 Make sure to purchase an external battery charger that is compatible with your laptop model because they are sometimes brand- and line-specific.


Use a Type-C Cable:

High-power connection is provided through USB-C ports, which transmit substantially more power at faster rates than a USB-A connector. You may use a USB-C cable to charge laptops that have built-in USB-C connectors.

Make sure the USB-C cable includes a plug adaptor if you’re wondering how to charge a laptop battery using a USB-C connection. Connect one end to an electrical outlet and the other to your laptop.

The Anker Premium 60W converter is a dependable USB-C adapter that can concurrently supply up to 30W of power to up to five USB-C devices at maximum speed. Four of those power connectors feature sophisticated designs that increase charging rates by automatically identifying the sort of item being charged. Even your phone may utilize the USB connector on the laptop to charge the battery.

Charge your Laptop with a Power Bank:

Using a portable power bank is another simple option to charge your laptop without a charger. Simply plug the power bank into the USB-A or USB-C connection on your laptop to get started.

If you want to use your laptop while it is plugged in, you should choose a strong USB-C power bank that is 8 volts or greater because USB-A power cords are often less powerful. Most power banks can only provide 5 volts, but most laptops require 8 to 12 volts to charge.

Undoubtedly one of the greatest selections for a laptop power bank is the Omni Charge 20+ 20000mah. It works well with the majority of laptops and electronic devices since it is compatible with a broad range of models, including 60W USB-C laptops and other 100W AC-compatible outlets. Additionally, the Omni Charge 20+ has two USB A ports, DC in/out, and pass-through charging, which enables you to charge additional devices while the power bank is being charged.

Utilizing a UPS Power Supply to Recharge Your Laptop:

In addition to providing surge protection, a UPS (uninterruptible power supply) has a battery that can run a laptop. You may estimate how long your laptop will be powered with our practical Laptop UPS Runtime Calculator.

Use your mobile device.

Using your cellphone as a backup power source, particularly in an emergency, can truly save your life. Simply attach one end of a USB-C cable to your laptop and the other to your smartphone using this method.

Go to your USB’s power settings and choose the “Power another device” checkbox. As your laptop starts up, you may anticipate that your phone’s battery will be swiftly depleted.

There are several disadvantages to this strategy because your smartphone doesn’t have the same amount of juice as a power bank:

• Your laptop’s battery life will be limited to 30 minutes; in other circumstances, a dead phone might be more troublesome.

Even while it’s not the best long-term fix for a dead battery, it’s still a useful tip that can help you out of a jam. 

Invest in a Universal Power Adapter:

Have you have an outdated laptop and charger that aren’t being made anymore?

It does not imply that your laptop has become useless. One choice is to buy a universal power adaptor. The numerous replaceable pins on this AC/DC device make it ideal for supporting a wide range of laptop models.

You may use your laptop while it charges using universal power adapters, which function exactly like your original charger. To prevent overheating your system or batteries, keep an eye on your voltage and amperage.

If you lose an important component, you can quickly replace them because they are also conveniently accessible online.

Charge your Laptop with your Car :

The ideal way to charge your laptop while travelling by car is right here!

You only need an AC adapter and a USB car charger. Excellent USB vehicle chargers are USB-A to USB-C converters.

Here’s how to use your car’s battery to charge your laptop:

1. Start the engine of your automobile.

2. Connect the vehicle charger

3. Attach the laptop’s USB-C connection

Since the majority of cars today have a USB connector, you won’t often even need a USB car charger.


The techniques on our list are excellent for starting up your laptop when you’re in a jam, despite the fact that some people would suggest it’s risky to use a laptop charger that isn’t from the official manufacturer.

If you don’t have a charger or power source handy, think about charging your laptop using any of these techniques, especially if you’re organizing a lengthy work trip.
