Charging a Laptop Without a Charger

Charging a laptop without a charger is an easy and challenging task at the same time. However, you can safely get your laptop back up and running by utilizing our solutions.

We’ll also discuss keeping a spare battery with you for emergencies. So without keeping you waiting, here are the 6 methods of charging a laptop without a charger.

Method #1: Use a Power Bank

Workaholics prefer to use power banks to charge their laptops in emergency conditions. A power bank is the safest and most convenient way to do the job.

Power banks come in a variety of shapes, sizes, and power. Unfortunately, most available power banks in markets have a maximum of 5V to offer. In contrast, the laptop requires 8V to 12V to get appropriately charged. So make sure to buy a power bank that supports 12V or higher.

To commence charging, turn on your power back, connect one end of the USB-C cable to the power bank and the other end to the USB Type-C port of your laptop.


Don’t forget that the power bank needs to get charged too. Make sure to charge it up before taking it with you.

Method #2: Use a USB-C Adapter

USB-C ports conduct much more power at a higher rate than a USB-A connector. If your laptop has a built-in USB-C port, you can connect it with a USB-C adapter via a USB-C cable and charge it without any trouble. The only drawback here is that you need to have access to a nearby power outlet to connect the USB adapter.


USB connectors have different shapes, configurations, and functions that might confuse you to identifying the USB Type-C connector.

The modern USB Type-C connectors support USB 3.1 and USB 3.2 technology and allow you to transfer data at 20Gbits/sec.

Method #3: Buy a Universal Adapter

If your laptop’s charger isn’t working and there’s a shortage of that model in the market, buying a universal charger is a perfect decision. Universal adapters have interchangeable connectors that can be used with any laptop model.


Excessive use of a Universal adapter leads to premature battery failure.

Method #4: Use an External Battery Charger

An external battery charger doesn’t need to be plugged into your laptop. You can simply take out the battery, mount it on the external charger, and connect the charger to an electrical power outlet. The flashlights on the charger will give you a signal when your battery is charged.


Make sure to buy an external battery charger according to your laptop, as these chargers are brand specific.

Method #5: Use a Smartphone

New smartphones models can be used as a power bank for your laptop. Although, they can give your laptop life for 30 minutes only. However, it’s the best solution if you are running out of time and don’t have a power bank with you or an electrical outlet nearby.

To initialize charging, connect your smartphone and laptop with the Type-C cable, and you are good to go!

Method #6: Use a Car Battery

Using a car battery to power up your laptop is very convenient, especially if you are on a road trip. Simply connect a power inverter to the car’s cigarette lighter socket and plug the laptop power cable into the inverter. Your laptop will start to charge instantly.

Keeping a Spare Battery

There might be occasions when your battery runs out, but you don’t want to wait for the laptop to charge first and then carry on with your work.

The best way to counter that issue is to keep a spare battery for emergencies. You can plug it into the laptop quickly and charge the original battery with an external charger, power bank, or any other means while using the spare one. So, no time is wasted, and the mission is accomplished.


In this guide about charging a laptop without a charger, we have discussed using a power bank, USB Type-C adapter, universal adapter, external battery charger, a smartphone, and using a car battery to charge your laptop. Moreover, we have discussed how a spare battery can be a lifesaver for you.
