What Is The Best Way To Charge A Laptop Without A Charger?

You can charge your laptop without a charger in a variety of ways. A power bank, which is a portable battery, may be used. You may use a universal converter, a vehicle battery, your smartphone, or a spare battery that you take along with you.

List of Alternatives to Using a Charger to Charge a Laptop

Have you ever been in a scenario where you don’t have power and your laptop is ready to die? If you know how to charge it, it’s not the end of the world. There are a variety of options, like utilizing a power bank, having an additional laptop battery, and more.

I’m certain that one of these techniques will assist you! So, let’s get started.

1.) Invest in a power bank

The majority of people choose this method since it is the simplest and most convenient way to charge computers without using charges. Portable power supplies for your laptop are known as power banks. Simply connect your laptop into the power bank, and it will automatically charge your laptop.


Power banks are available in a range of colors and forms. As a result, they’re all designed with different charging capabilities. Power banks are usually capable of charging your phone’s battery once or twice. This is particularly true when trying to charge a high-capacity laptop.

Power banks must also be charged. When your power bank runs out of juice, you won’t be able to charge your laptop with it. As a result, I recommend keeping your power bank charged so that you may use it anytime you need to go out on the spur of the moment but your laptop isn’t charged.

However, make sure you pick a power bank designed for laptops, since many on the market only provide 5V USB output, while laptops need a greater voltage than smartphones. Depending on your device’s specs, a laptop would need a high voltage output of 16V-20V.

2.) Charge your battery using USB Type-C.

The most popular laptop connection is the USB connector. The USB Type-A and USB Type-C connections will be discussed.


The Different Port Types

USB ports are the most popular method to charge and connect items to your laptop. They come in a variety of forms, sizes, and configurations, each with its own set of characteristics that may be difficult to comprehend. The USB Type-A and USB Type-C ports will be discussed today.

Type-A USB Port

This USB port is flat and rectangular, and it is often seen on laptops. The Type-A USB is readily identifiable.

The USB Type-A connections may handle USB 2.0, USB 3.0, and USB 3.1, depending on the hardware you have. Data transmission, power output, and connection to other devices like as printers are all available via Type-A USB ports.

Type-C USB Port

This USB port has a more contemporary design than the USB Type-A connector, and it has a unique look. The connections on the Type-C port are the same size as those on the micro-USB port. The Type-C USB ports have an oval shape to them.

Type-C USB ports feature USB 3.1 or USB 3.2 technology, allowing for data transfer rates of up to 20 gigabits per second. The Type-C USB port has all of the same capabilities as earlier USB ports. However, a key feature of the Type-C USB connector is that it also provides power input. This function enables you to charge your laptop without having to use a particular brand of charger.

Using a Type-C USB connector to charge your laptop

You’ll need a power bank and a USB Type-C connection to utilize this charging technique. All you have to do is use the Type-C USB connection on your laptop to connect it to the power bank.

Most computers, on the other hand, run on eight to twelve volts, while most USB connections for charging can only provide five volts. If you need to use your laptop while charging, you’ll need a laptop-compatible power bank.

3.) Make use of an adapter that is universal.

If you have an older laptop, the charger for it is likely to be discontinued. What would you do if it malfunctioned? Fortunately, you may charge your laptop using an adapter instead of the model-specific laptop charger.


Universal adapters are AC/DC connections that come with a variety of connector tips. These suggestions work for a variety of different brands. Fortunately, you do not need to buy the whole collection to get a particular tip. If you just need one tip, you may purchase it individually.

Universal adapters work in the same way as the original charger for your laptop. You may also use your laptop while charging it using a universal charger. If you set your amperage too high, though, you risk harming your battery. Because the high amperage may cause your laptop to overheat, resulting in a damaged battery, I recommend that you utilize universal adapters with care.

4.) Utilization of a Car Battery

If you spend a lot of time on the road, you’ll probably need to charge your laptop when away from a power outlet. Without access to standard wall power outlets, most conventional chargers will not function. Fortunately, you can charge your laptop using the battery from your vehicle.


The most popular method of utilizing your vehicle battery to charge your laptop without a charger is to use a power inverter. Power inverters may be simply connected into the cigarette lighter outlet in your vehicle. They may be used to power equipment that need 300 watts of continuous power, which is more than enough for your laptop.

The disadvantage of this approach is that you now have a large gadget on your car’s floor. Despite this flaw, this option is still valuable since it is simple to implement. Another issue with this approach is that laptops do not have a built-in voltage regulator.

The majority of gadgets designed for vehicle usage include built-in voltage regulators that change the battery voltage appropriately. Laptops, on the other hand, are intended to have their own AC adaptors that handle all of the regulating, so charging your vehicle with your car batteries may be a little difficult.

Using an AC adapter to charge your laptop with your vehicle battery is another option. On one side, you’ll need to connect a USB Type-A connection, and on the other, a USB Type-C connector. All that remains is for you to connect the USB charger to your laptop at this point.

5.) Keep a spare battery on hand.

Spare components are available from laptop manufacturers. If you will be away from a power source for your laptop, purchasing an additional battery is a simple method to ensure that you have enough power while you are gone.


You may buy an external battery charger to charge your extra battery quickly. You may connect these external battery chargers into your wall and use them to charge your laptop battery. You’ll be able to charge your laptop and a backup battery at the same time using this gadget.

Laptop manufacturers, on the other hand, have created external chargers that are unique to their models. If you opt to purchase an external charger, be sure it is compatible with your laptop.

6.) Use a laptop battery that can be charged externally.

One of the smart ideas for charging a laptop without a charger is to use an external rechargeable battery. If your laptop charging port is damaged or you want to conserve electricity, this is a great alternative.


However, select a brand-specific-battery that matches your laptop if you buy an external charged laptop charger, otherwise you’ll wind up with the incorrect one.

The majority of these externally charged laptop batteries feature LED indicators that allow us to see how much power is left in the battery.

7.) Make Use Of Your Phone

In an emergency, this technique is generally employed as a last option. The majority of cellphones can be used as power banks to charge your laptop. For obvious reasons, your smartphone will not be able to power your laptop for a long amount of time.


Even if your battery runs out, you’ll probably only be able to keep your laptop powered for thirty minutes. The price for thirty minutes of battery life is basically a dead phone battery.

Even if the advantages are temporary, this is still a good option if you don’t have any other options and need to use your laptop right away. So, how should you go about utilizing this method? A USB Type-C cable is required. With this cable, you may connect your laptop to your smartphone, then pick the suitable choice and finish.
