Or in case your charger suddenly stops working. Now you panic when you stand next door for a presentation, or you want to enjoy your favourite movie while camping outside. But don’t worry by reading this article on how to charge a laptop without a charger; you can set a laptop without a charger

The chargers that come with your laptop are specially designed according to the make and model of the connected battery.

The current rating or pin sizes are all different, and there is rarely a possibility that you can use another laptop’s charger to charge the battery. They can trust, but regular use can seriously damage the battery or plug.

If your charger doesn’t work, find out what’s wrong with the charger, cable, or battery. Once you have your answer, we can find a solution.

Well, aside from the charger that came with your laptop, there are some simple tips and tricks that can get you out of this crisis.

So if you don’t have the charger or if it is broken and you urgently need to charge the battery, here are some tips for charging a laptop without a charger. Safe and efficient way because we don’t want the battery to explode and burn in the laptop socket.


8 Different Ways To Charge A Laptop Without A Charger

Technology has come a long way, and there are certainly plenty of ways to find a simple yet innovative solution to recharge your laptop battery. Here are some simple steps that will help you charge your laptop battery without the charger.


1. In the car

In the car

If you are travelling or going to a meeting, charging your laptop with the car battery is a good tip as we often set our phones in the car.

You have to consider the required voltage for the computer, which is usually between 18-21V, while cars have a 12V battery.

You can charge your laptop battery in two ways with your car battery

  • Use a USB charger that has a Type A connector and a Type C connector that plugs into the laptop at the same time to provide power. It can be connected to the charging port of the car.
  • You can also use an adapter and charge it from the cigarette lighter.

Inserting an inverter into the charging port or cigarette lighter hole before the adapter can prevent damage to your car battery and laptop.

  • To connect your laptop for charging from the car battery:
  • Start the car, because while it is running, the car battery is charged and not discharged
  • Now plug the inverter into the cigarette lighter
  • Now insert your adapter into the slot of the inverter
  • And connect the power adapter to your laptop

Also, with a USB charger.

  • Start the car
  • Plug in the car charger or now on newer models you have a built-in USB port
  • Connect the USB C end to the laptop for charging.

2. With an external battery charger

With an external battery charger

If there is a problem with the charging slot and the battery does not charge when connecting the charger. Then you can purchase an external battery charger to charge the battery. External battery chargers are devices that hold the battery and charge it directly from a wall outlet.

Although you cannot use an external battery charger, buy one compatible with your battery current and wattage, as batteries designed for different laptop models have other specifications.

External chargers have lights that indicate when the battery is charging and when it is fully charged so you can plug it in.

This method is effective when there is a problem with the laptop charging port or battery connection.

But since the cost of the external charger is the same as the cost of the laptop charger, not all brands can remove the battery and may also void the laptop warranty. Therefore, it will not be practical or advisable to invest money in it.


3. Power bank

Power bank

Investing in a power bank is a great solution for charging a laptop when you don’t have plugs to a plugin or when the charger fails for travellers and people who are always on the go.

Power banks are very efficient as they can quickly charge various devices such as phones, headsets, MP4 players and laptops. Just keep an eye on the voltage as general power banks can charge up to 5V while laptops require 12V, so buy one that is compatible with your laptop battery.

Connecting a powered laptop is easy; all you need is a USB Type-C cable to power and charge the computer while you enjoy the ride.

The advantage of using a power bank is that they store many charges, so you can quickly charge a laptop battery for a battery life of up to 1-2 hours, plus they are lightweight and portable, so there is no need to carry extra charges or leave. Put the car in gear to charge.


4. USB C with adapter

USB C with adapter

If your laptop has a built-in USB C port, you can charge your laptop battery like a phone through a USB Type-C adapter, connecting it to the wall, in the car, to the phone or the power bank.

These adapters are readily available, but make sure you get the correct rating when purchasing. Charging with a USB-C adapter is much safer than a car or power bank, as the adapter shuts down with voltage fluctuations and won’t degrade your laptop’s battery.


Can you charge a laptop with USB-C?

This is also a common question that many people ask themselves. It just depends on the type of USB port your laptop uses.

If you are currently using a wired mouse or keyboard and unplug one, you will see a rectangular connector on the end of the cable. It is the piece of metal that is inserted into the computer. This is called a USB Type-A connector.

This is the most common USB connection, and when you talk about USB, you quickly think of USB type A. For example, your mobile phone uses a USB type A link.

Unfortunately, although you are effectively using USB Type-A for your smartphone, Who cannot use it to charge your laptop.

Type A exchanges a lot of data but cannot supply the enormous amount of power needed to charge your laptop. Type A cannot provide enough power. However, USB 3.1 offers a connector called USB Type-C or USB-C.

Unlike type A, type C has a more oval shape. It is designed to transfer high-power connections, meaning it can move more power than Type A, even much faster. In short, you cannot charge your laptop with USB Type-A, but you can set your computer with a USB-C connection.


How to charge a laptop with USB-C?

Please make sure the cable has a plug adapter, a box-shaped plug on the end of your phone’s charger, then plug it into a wall outlet. Most laptops use a USB-C cable as a basic charger.

To charge your laptop via USB-C, plug one end of the USB-C cable into a power outlet and then connect the other end of the USB-C line to your computer.

That’s all! A breeze. As long as you have permanent access to your USB cable, but it could be a problem, what if you can’t access it? Unfortunately, buying a new USB-C line may not be easier than buying a new laptop charger.

And it may not be possible to pass by a computer store at some point, such as if you are stuck on a Caribbean island for a wedding ceremony.

But every time you visit a market to buy a new laptop, consider buying one with at least one USB-C port. The USB-C connector is becoming more and more popular.

Who can assume that most laptops will have USB-C ports in the future, leading to the removal of USB Type-A?

The point here is that more people will likely have USB-C cables in the future, so there’s a higher chance someone will lend you one if you accidentally lose theirs. From now on, you need to find someone with the exact type of laptop charger you own, which can be a bit of a hassle.

In addition, USB-C chargers are becoming my favourite laptop chargers because they are stylish, durable, fast and efficient.

Not to mention that most devices are USB-C compatible, so if you accidentally break the one on your laptop, you can borrow the one from your printer or power bank until you replace the broken one.


5. Universal charger

Universal charger

If your charger is broken and you can’t find your brand charger anywhere, a universal charger is for you. Universal chargers are suitable for all makes and models of laptops as they come with different rating settings and tips for connecting each laptop charging port.

Universal chargers are not only safe and efficient to use, but they are also affordable and ideal for people who want a charger for multiple laptops of different brands or models. These chargers also have a port to connect to the car’s charging port, making it super portable and convenient.

Keep in mind that when connecting your charger, you need to choose the correct tip and rated voltage; otherwise, the higher voltage or current will damage your laptop and battery.

These chargers’ multiple tips and charging settings are undoubtedly one of the best solutions for charging a laptop without a charger. They work the same as your laptop charger, and you can efficiently work on the computer while setting.


6. Use the super battery in the laptop

Use the super battery in the laptop

Super batteries are replacements or extra batteries made for your laptop. These batteries are similar to your battery in every way but are charged via the separate cable that plugs directly into the battery. Once your battery is set, you can replace your laptop battery with an external battery.

Super batteries can provide up to 4-5 hours of backup, and you need to buy a specific battery that is compatible with your model and an external charger.

These batteries are a good tip but not as effective in an emergency. And why would someone carry an extra battery and charger when they can use a more straightforward solution?


7. With a phone

With a phone

If you have no choice but to recharge your laptop battery, your phone could save your life. You are wondering if this is possible? Yes! You can charge your laptop battery with your phone.

While phone batteries are much smaller than those in your laptops, they won’t charge much until they’re dead. But for urgent cases, the phone can be your last resort. Save yourself from this mess.

For this, you need a USB-C charging cable with a Type-C line at both ends.

  • Now connect the laptop and phone at each end.
  • A dialog box will appear on the phone screen.
  • Check the option “power the connected device”
  • Now the laptop starts charging.

This method isn’t entirely safe for your phone and laptop batteries, and you shouldn’t go there unless it’s your last hope in an emergency.


8. With HDMI Cable

With a phone

Today most laptops have gone wireless, making it possible to be mobile with the computer (mandatory). But sometimes you will not find a business opportunity. The only option is to charge your laptop with a USB-C and HDMI cable. 

Using a laptop’s HDMI port is a simple, efficient, and cost-effective way to charge your computer. Once a power source is available (LCD or LED TV that supports HDMI) and a USB-C compatible device, they can serve as an alternative. It is not recommended to charge your laptop in this way.


Can we charge a laptop with HDMI?

Your laptop charger is likely malfunctioning at a critical time. Right now, you may not be able to run to the store to buy a new charger, so where are you?

The sad thing is that once the laptop battery runs out, you can’t do anything with it until it turns on. So, what is your alternative in this devastating time?

To respond to the question; Yes, you can charge a laptop with HDMI if you can find a device that supports it. Gone are the days of being stuck with your laptop charger not working correctly; you are good to go as long as you have a laptop with an HDMI port.


How to charge a laptop with HDMI?

Charging a laptop with HDMI is the first option we’re going to show you. If lost or faulty chargers, follow these steps to trust your computer with an HDMI cable.

First phase

You need to make sure that your laptop has an HDMI adapter cable and adapter or connector to convert HDMI.

Otherwise, this alternative charging source wouldn’t work for you because the HDMI cable is practically useless without the connector or port. The first step is, therefore, to ensure that the necessary resources are available.

Second phase

Connect the HDMI cable to an LCD TV that supports HDMI, use the HDMI connector and connect another end of the HDMI cable. If your laptop has an HDMI port, this method is better for you because you don’t need many accessories.

You only need a few items to charge your laptop with an HDMI cable. This holder can trust a computer, as well as a laptop and a Chromebook.

Third  phase

Recheck the connection to see if the HDMI port is working correctly. If you notice that the laptop turns on, it means that the computer is charging correctly.

If not, you may need to disconnect and reconnect the HDMI cable to the laptop until you notice a difference. If all you get is static, it could mean something is wrong with the power supply.

To use this method to charge your laptop, you’ll need some items, such as a TV that supports an HDMI input port and an HDMI cable.

For your connection, connect the HDMI cable to the HDMI connection on your TV and connect the HDMI adapter cable to the port on your laptop. Laptops come with specialised charging adapters that help regulate voltage and current to charge your computer.

In typical situations, HDMI is used for big-screen movies and high-quality audio systems. HDMI supplies a small amount of voltage or current, which may not be suitable for electrical devices.

However, charging your laptop with an HDMI adapter is only recommended if it is seriously stuck somewhere. Otherwise, it is recommended that you use the charging adapters that come with your laptop.


Is it safe to charge your laptop without the official charger?

If you don’t know what you’re doing, using different methods to charge your laptop can be dangerous for the battery. It would help if you made sure that the voltage and wattage match the specifications of your laptop charger.

The official charger or the approved replacement is the best way to power your laptop in all scenarios.


Frequently Asked Questions

Can you charge a laptop with HDMI?

Yes, but most devices that require power to function will need a plug or cord that connects directly to an outlet.

How do I manually charge my laptop battery?

First, turn off the computer. Unplug the AC power cord from the wall outlet. Plug in a DC power adapter, often called an AC-DC converter, so you can then plug in another type of electric cord that interfaces with your laptop’s charging port.

Then plug it into a wall socket or power strip that is on but not currently supplying electricity to anything else. Ensure there’s nothing else plugged into the other end of this extension cord/power strip before turning the unit back on, or you may cause an electrical overload near your device.

Can you charge a laptop with a USB-C phone charger?

Yes. A laptop can be powered by a phone charger, as long as it is the proper voltage and amperage (Watt). You will need to use a USB-C to USB-C charging cable that supports 100-watt power delivery and PD 2.0 fast charging plus.
