Losing a laptop charger happens to almost everyone at some point. But since some laptop batteries are powerful enough to power the system for about nine hours, it doesn’t have to be a problem.

However, if your battery is low and the charger is missing or broken, you may start to worry.

Fortunately, you don’t have to fear losing important files or leaving a Zoom call unexpectedly if you’re prepared.

There are many solutions for charging a laptop without a charger and they should all fit in your laptop bag or backpack.

How to charge a laptop without a charger

Charging your laptop enough to finish your work or save files can be done anywhere, even without a charger, if you’re prepared.

One of the first methods that come to mind is to use a power bank. Traditionally, power banks are associated with backup solutions for smartphones, tablets, Bluetooth speakers and other similar mobile devices.

But the right power bank can also charge your laptop.

However, it is important to remember that the average 5V power bank is not enough to charge laptops. Therefore, finding one that matches the voltage of the laptop is essential. You can do this by checking the voltage of the adapter, which is usually 12V.

You can use power banks with type C connectors.

How to charge a laptop without a charger port

The best thing about modern laptops, besides their impressive technology, is the wide range of ports.

This means that many laptops can still be charged even if the charger port is damaged.

Use a type C cable

If the charger port doesn’t work, you can use a Type-C connector to power your laptop from a different source.

Here you have multiple options.

You can use a Type-C connector to power the laptop from a compatible power bank. Alternatively, you can connect the Type-C cable to an adapter and draw power directly from a wall outlet.

Given the rapid increase in the use of Type C to deliver power and data, more and more devices feature USB-C ports.

And unlike a power bank, the Type-C adapter method is cheaper, more reliable, and faster.

Use an external laptop battery

External laptop batteries are similar to power banks, but they store more power and don’t take power away from your other mobile devices or smartphones.

Using an external laptop battery is a great idea when your laptop battery is dead or the charger port is not working.

You can connect the battery to your laptop using a Type-C cable and then to a wall outlet to give your laptop all the power it needs.

How to charge a laptop without a charger using your phone

Should you use your phone to charge a laptop? Probably not. Although it’s not an ideal way to supply power to your laptop, that doesn’t mean it can’t be done.

Think of the phone charging method as a last resort in extreme situations when you need a little power to save your files, complete a task, send a message, etc.

This is how you do it.

  1. Connect Laptop to Phone with Type C Cable

  2. Go to the charging device option in your notifications menu.

  3. Press the option to supply power on the phone screen.

It won’t give your laptop much to work with, especially if it’s not charged to at least 90%.

But there are some caveats to this method. First, it requires a Type C to Type C cable. Second, it depends on the phone being able to lend power to another device.

Lastly, it is best to use it on a very low power laptop to prevent the phone from draining too quickly.

How to charge a laptop without a charger or power bank

What happens if you don’t have a charger or power bank? In fact, what if you’re not even home?

Maybe you’re traveling or camping and your laptop runs out of battery. Are there alternative ways to charge your laptop enough to be able to use it?

Method 1

If you have a USB-C port on your laptop, you can charge it with your car battery. This method requires a USB port pre-installed in an accessory port such as the cigarette lighter. Of course, any other USB port will work.

If your car meets these requirements, you can connect the Type-C connector to the USB-C port of the laptop and place the other end into the USB port of the car.

The best cable to use in this situation is a Type A to Type C cable.

Method 2

Imagine that your car does not have USB connectivity because it is an old model. That’s not a problem. The car still has a battery that you can use to charge a laptop.

You only need one additional device: a power inverter.

A 300W or higher power inverter should be more than enough to safely charge many mid- to high-end laptops.

This is what you should do.

  1. Connect the inverter to the car battery using cables.

  2. Connect the laptop to the inverter using a Type-C cable.

This method is efficient when camping, performing maintenance or repairs on your car, experiencing a power outage, etc.

That said, remember that car batteries can drain quickly if you’re not driving. Depending on the power, inverter, and battery quality of the laptop, it may take a couple of hours to fully charge it.

Frequent questions

Does USB-C charge faster?

USB-C charging is no faster or more powerful than using a traditional charger. USB-C connectivity regulates power flow differently than AC adapter charging.

Although you can use Type-C cables to power a laptop from a power bank, wall outlet, car USB port, and other sources, it won’t always transfer enough power to charge the battery and sustain the system simultaneously.

Can you use a universal adapter on a laptop?

Universal adapters are great backups for original laptop AC chargers. Some even come with interchangeable cable tips making them compatible with multiple brands.

Remember to check the rating and requirements of the universal adapter to make sure it meets your laptop’s specifications. Please note that charging may be slower than using an original AC charger, but should work fine in most cases.

Always be prepared

You never know when you might suddenly run out of power or find yourself in a sticky situation. Power problems can be even more common if you are also working with a faulty or damaged battery in your laptop.

Fortunately, modern laptops come with many solutions for charging the battery, running the system, or getting enough power to complete essential tasks without a charger.

Being prepared is a matter of having some Type-C cables on hand, a good power bank, making sure your car has a spare USB port, or simply carrying an extra universal adapter with you.
