Placing the laptop charger incorrectly happens to almost everyone at some point. But since some laptop batteries are powerful enough to fuel the system for about nine hours, that shouldn’t be a problem.

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

Fortunately, you don’t have to worry about losing important files or unexpectedly dropping out of a Zoom call 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

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

One of the first methods that comes to mind is using a power bank. Traditionally, power banks have been 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, it is essential to find one that matches the voltage of the laptop. You can do that by checking the voltage on the adapter, which is usually 12V.

You can use power banks with Type-C connectors.

Charging laptop without charger port

The great thing about modern laptops, apart from their impressive technology, is the wide array of ports.

This means that many laptops can still charge even if the charging port is damaged.

Use a Type-C cable

If the charging port is not working, you can use a Type-C connector to power your laptop from another source.

Here you have several options.

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

With the proliferation of Type-C usage for delivering both power and data, more and more devices have 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 store more energy and don’t steal power from your other mobile devices and smartphone.

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

You can connect the battery to your laptop with a Type-C cable and then to a power outlet to give your laptop as much power as it needs.

Charging laptop without charger with phone

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

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

Here’s how it’s done.

  1. Connect the laptop to the phone with a 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 doesn’t give your laptop much to work with, especially if it’s not at least 90% charged.

But there are some caveats to this method. First, a Type-C to Type-C cable is required. Second, it depends on whether the phone can power another device.

Finally, it is best used on a very low wattage laptop to avoid draining the phone too quickly.

Charging a laptop without a charger and 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 on the road or camping and your laptop has run out of power. Are there alternative ways to charge your laptop enough for you to use it?

Method 1

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

If your car meets these requirements, you can plug the Type-C connector into the laptop’s USB-C port and plug the other end into the car’s USB port.

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

Method 2

Imagine your car doesn’t have a USB port because it’s an older model. That’s no problem. There is also a battery in the car that you can use to charge a laptop.

It only needs an additional device: an inverter.

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

Here’s what to do.

  1. Connect the inverter to the car battery with cables.
  2. Connect the laptop to the inverter using a Type-C cable.

This method is efficient when camping, servicing or repairing your car, power outages, etc.

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

Frequently Asked Questions

Does USB-C charge faster?

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

While you can use Type-C cables to power a laptop from a power bank, wall outlet, car USB port, and other sources, it will not always transfer enough energy to charge the battery and run the computer at the same time. system support.

Can you use a universal adapter on a laptop?

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

Don’t forget to check the rating and requirements on the universal adapter to make sure it meets the laptop’s specifications. Please note that charging may be slower than with 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 issues can become even more common if you’re also working with a sub-par or damaged battery on your laptop.

Fortunately, modern laptops have many solutions for charging the battery, running the system, or getting enough power to perform 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 free USB port, or just having an extra universal adapter with you.
