What to Do If You Don’t Have a Charger for Your Laptop

Every laptop has an integrated battery, and some older models have removable batteries as well. All you have to do to charge the battery is supply it with power via the appropriate charging adaptors and cable.

When we plug our laptop into a power outlet in our home or office, electricity flows through the cable and into the battery.

A dedicated laptop charger is the most efficient way to transfer electricity to your laptop battery, even though there are other options. But here in this article let us see how to charge a laptop without a charger

All you need is an electrical energy source and a device to transfer that energy to the battery.

Let’s get started.

1. Power Bank to Charge a Laptop

One of the most convenient ways to charge your laptop is with a power bank. A power bank is a portable battery pack for your laptop.

All that remains is to connect your laptop to the power bank. However, you must ensure that your laptop has a USB Type-C port.

When using this method, make sure that your laptop’s input DC voltage matches the Power bank output voltage.

The best thing about power banks is that you don’t have to plug them into a power outlet always.

Depending on the model, you may be able to charge your laptop via one of its USB Type-C ports. When there are no other options for charging your laptop, you can use a power bank in the same way that you would charge your smartphone.

Most laptops require 8 to 12 volts of power, but most power banks only provide 5 volts, necessitating the purchase of a power bank that supports 12 volts or higher.

As a result, you should always have a power bank capable of charging laptops on hand. Keep in mind that the power bank must be rated at least 18 volts to produce the desired effect.

A large power bank can also charge your laptop while remaining portable, allowing you to take it with you wherever you go.

Power banks come in a variety of shapes and sizes, and not all of them can charge the same devices. A USB Type-A power bank can be used to charge low-power devices.

A USB-C-based power bank is required to charge a more powerful laptop, such as a mobile workstation. USB-C power banks can also be used to charge other USB devices, such as your smartphone or tablet.

Only data transfer and power output are supported by the USB Type-A port. It cannot be used to supply power.

Because of the development of USB type B and, more importantly, type C, not only are fast data transfers possible but also power input and output.

Anker PowerCore+ 26800mAh PD 45W with 60W PD Charger Power Bank is an excellent choice for charging your laptop because it can deliver up to around 60W of power. You can check its latest price on Amazon.

Your power bank will probably only be able to charge your laptop battery one or two times, especially if you’re charging a more powerful laptop.

It is critical to remember to recharge the power bank by plugging it into an electrical outlet. After your power bank runs out of charge, you won’t be able to recharge your laptop.

As a result, it’s best to only use your power bank when you need it. It is a good idea to keep your power bank with you at all times in your laptop bag.

2. Charge a Laptop in a Car

If you are the type of traveler who spends more time on the road than in the office, you can charge your laptop with your car battery.

How to charge a laptop in a car?

When you’re on the road, you can also use the car’s electricity. Nowadays, most cars have USB ports on their dashboards, and charging your laptop is simple.

In this case, a simple USB type-A to USB type-C converter cable should suffice. Connect one end (Type A) to the car’s USB port and the other end (Type C) to your laptop.

If your car lacks a USB port, you must use a car charger adaptor, which provides USB ports to connect.

When charging the laptop, the car engine should be turned on. Otherwise, the battery charge in the car will be depleted.

However, both of these methods are only applicable to laptops with low power requirements. A portable car inverter is required to charge high-power laptops.

Because most modern laptop batteries have voltages of 8V or higher, and automobile batteries are rated at 12V, connecting the laptop directly to the battery is dangerous.

Even if the voltage is less than 12V, connecting your laptop directly to a car battery is not recommended. You should proceed with caution because if you do not use this method correctly, you may end up with a dead battery or damage your laptop.

An inverter is the most efficient way to convert power from a car battery to charge a laptop, especially when a high-power laptop is required.

Inverters that generate AC from a DC source and have output power ranging from 12 to 24 volts are available. Most people have an inverter in their car, especially when going on a vacation trip.

With an inverter like the BESTEK 150W Power Inverter, (Amazon link) you can power anything that requires up to 150 watts. It may not be sufficient to run power tools, but it will more than suffice to charge your laptop in this case!

If you have an inverter, you can easily charge your laptop in a car by plugging the inverter into the cigarette lighter socket. Simply follow these simple steps:

  • Insert the inverter into the cigarette lighter socket of your vehicle.
  • Connect the USB of the laptop to the inverter USB port.

That is all.

The disadvantage of this strategy is that the power inverter must be left in the car. Never leave your laptop unattended and in plain sight in a car. It may be more vulnerable to theft or damage from overheating.

3. USB Type-C Adapter to Charge the Laptop

Can you charge a laptop with a USB?

If you’re fortunate enough to have a USB Type C port on your laptop, you shouldn’t be concerned. A USB Type C cable can be used to charge the laptop.

Just make sure the cable comes with a power adapter. One end of the cable has a box-shaped plug that can be plugged into a power outlet.

Unlike Type A, USB-C has a tiny oval-shaped connection optimized for high-power connectivity. It can transfer more power at much faster speeds.

A USB Type-C adapter, such as the Amazon Basics 65W USB Type-C Wall Charger, charges your laptop in the same way that a power bank does.

However, it must be connected to a power source, whereas a power bank is a stand-alone power source.

It is one of the safest ways to charge via USB-C because the adapter includes a safeguard that disables charging when it detects excessive heat or other issues.

You can charge your laptop here by plugging in the power plug and connecting the USB-Type C connector to your laptop.

4. Universal Power Adapter to Charge Your Laptop

This section will cover how to use a universal adaptor as an alternative charging method for laptops.

However, regardless of the charging method, always check the voltage feeding to the laptop. These universal chargers come with a variety of input tips, so you should be able to find one that works with the charging port on your laptop.

Individual tips can also be purchased. Some universal adapters can even charge your laptop with 12V DC power from a car or other 12V DC power sources. When connected, the adapter will not only power but also charge the laptop.

It’s wonderful to know that you can charge your laptop battery without the original charger. However, when using these types of universal power adaptors, you must exercise caution.

If the output voltage of this adaptor is greater than the required voltage for the laptop, you will most likely have a dead or failed battery which may cause the laptop to be destroyed.

This universal laptop adaptor is compatible with a wide range of brands and they are easily available on Amazon.

5. External Battery Charger to Charge the Laptop Battery

An external laptop battery charger is a stand-alone device that is not connected to your laptop. Rather, you take the battery from your laptop, place it on the charger, and then connect the charger to an outlet.

This method is incompatible with laptops that have built-in batteries. Most external laptop chargers have indicator lights that flash when the battery is charging and then remain steady when the battery is fully charged.

External laptop chargers are typically brand-specific, so find one that matches your laptop’s specifications. Many of the battery packs can be charged through your car’s 12-volt cigarette lighter, making them truly portable.

6. Use a Laptop Backpack with a Built-In Battery

Why carry a second battery when your backpack already has one?

Backpacks with built-in batteries are an easy way to always have a battery on hand, especially if you require the extra storage space that such a bag provides.

Consider the Matein Travel Laptop Backpack available on Amazon. This USB backpack, has a built-in USB charger on the outside and a charging wire on the inside, making it easy to charge your laptop while traveling.

7. How to Charge Laptop with HDMI

Using an HDMI cable to charge a laptop is a relatively new concept, which is but it should only be used in an emergency.

Not all laptops can get electrical power over HDMI. Ensure that your laptop has a useful HDMI IN port. To see if your laptop can, learn the user manual and seek the “power over HDMI” or “HDMI charging” function.

Charging a laptop over HDMI will take longer than using a power adapter. This is because electricity passes through at a slower rate than a power adapter, therefore the laptop will take longer to completely charge.

There are two typical ways to charge a laptop over HDMI; let’s look at how each is done.

1. Charging with HDMI to HDMI Cable

Step 1: To charge the laptop, connect the HDMI cable to both the HDMI-IN port on the laptop and the HDMI-Out port on the power source (preferably a TV or monitor).

Step 2: Check for a power symbol in the system tray (on the battery icon). If you hover over the sign and see “plugged in,” you can use this approach.

Step 3: Once the power is on, your laptop should begin charging.

2. Charging with an HDMI-to-USB adaptor

Most laptops now include a USB-C port so you can use an HDMI-to-USB converter to charge your laptop via HDMI.

This allows you to effortlessly connect a laptop to a power source (such as a television or monitor) and charge it via the USB connection. Follow the instructions listed below.

Step 1: Connect the HDMI end of the cable to the HDMI-OUT port of the appropriate power device.

Step 2: Connect the other end to the HDMI port of the converter, such as the Anker 310 USB-C adapter (view on Amazon), for fast and efficient transfer.

Step 3: Connect your laptop to the HDMI-to-USB-C converter via the USB-C port.

Step 4: Check the battery symbol on the Windows taskbar system tray. If your laptop shows a plugged-in symbol, it is charging.
