How To Charge Dead Laptop Without Charger

Every laptop is designed to work with a built-in battery as a power backup when there is a power outage. To charge these batteries, there is a need for a power supply. This means that for a dead laptop battery to come back on, you will have to connect it to a power source using your laptop’s power cable. But you can use a few more options to restore the laptop battery’s power.

So, use the following ways:

  • A Type-C USB Adapter
  • Charge Laptop in Car without Inverter
  • Charge a Laptop with a Power Bank
  • Charging a Laptop with a Car Battery
  • A USB Type-C Cable

We will now go over these steps in detail to help you understand each process.

  • A Type-C USB Adapter

Suppose you cannot access a power bank or car battery. In that case, there is another alternative that you can utilize to power up your laptop battery. We are referring to a Type-C USB adapter. The USB-C is somewhat different from Type-A due to its smaller oval-shaped connector. The USB Type-C is designed to offer higher connectivity than Type-A, which means you can get a faster-charging speed with the USB Type-C.

The charging speed of the USB Type-C is pretty similar to that of a power bank. However, while the USB-C would require a power source, the power bank is self-powered, and it only needs to be charged. You can find an excellent Type-C USB adapter for your laptop on most online stores like Amazon.

What makes this adapter one of the most protective means of powering your battery is its self-shut down when high heat is detected.

If you wish to know how to use one of these Type-C USB adapters to power up your laptop battery, follow the link below:

  • Charge Laptop in Car without Inverter

You already know that cars have electricity. So, regardless of where you are or what you are doing, charging your computer in a car is pretty simple. To do this successfully, however, you will need an AC adapter. The kind that has a Type-C connector on one end and a Type-A connector on the other end. Also, you will need a USB car charger.

Here are the simple steps to follow:

  • The first you would want to do is turn on the car’s engines.
  • Then connect the car charger to the port provided in the car. You may find a USB port for the cable, given that many cars come with it.
  • Finally, connect the USB Type-C connector to the computer system.

  • Charge a Laptop with a Power Bank

The power bank option is one of the simplest ways to power up your laptop battery without a charger and is why most people choose this option. Having a portable power bank for your computer system is essential, especially when there is no option available for power. At this point, all you can do is connect your laptop to the power bank using a USB-C cable.

These power banks come in various shapes, colours, and charging capacities. With such capabilities, you can revive your laptop battery once or twice. This does vary, given that some laptops are high-powered.

As you already know, your power banks can run out of power, leaving you with no choice if there are no other available power sources. Therefore, keeping your power bank charged is crucial to prevent being stranded.

Although using a power bank proves to be quite simple, you must make sure to use a power bank that offers a voltage that meets the requirements of your computer. For example, most smartphone power banks provide a voltage of about 5V USB output but are not ideal for a laptop system. If you want to purchase a power bank for your laptop, ensure it is between 16 to 20 volts. For better precision of choice, check the specifications of your computer system.

4. Charging a Laptop with a Car Battery

First things first, do not connect your laptop directly to your car’s battery. Connecting your laptop directly to your car’s battery is one of the most dangerous actions anyone can do. This is because, during the charging process, there is a likelihood of an explosion, which is something you do not want to experience.

However, you can use the power from your car to charge your computer safely. The most common method is using a power inverter. It is relatively cheap and works with different types of laptops.

Here is a virtual demonstration of using a power inverter to charge a laptop battery and any other electronic device.

These power inverters come in different types and capacities as well. Some of these inverters, like the Betek 300-Watt Power, come with two added three-prong plugs to connect to the car’s outlet. Also, they are designed to have a couple of USB ports that allow you to connect your computer’s adapter right into the inverter. There are additional USB ports provided for other necessary gear.

How to Charge a Laptop with USB-C

There are three main types of USB cables: Type A, Type B, and Type C cables. However, the most suitable USB Type cable for powering a laptop battery is the USB Type C cable. This USB cable type supports high-wattage connectivity, making it preferable to Type A and B.

How to Charge a Laptop with USB-C

While the Type A (3.1) cable will provide a speed of 10 GB/s, the USB Type-C (3.2) cable offers up to 20 GB/s.

It is possible to power a computer system with a built-in Type-C port with a Type-C cable. So, if your system has such a port, that will make things relatively more straightforward. But for this to be successful, the cable must have a plug adapter. This is the part of the cable that goes into any possible outlet. Interestingly, you can find specific laptop systems with this USB type as their main charger.

To begin the charging process using the USB Type-C cable, fix the end of the Type-C cable into an outlet. Finally, connect the other end of the Type-C cable to the computer system. With these few steps, you can power up the dead battery of your computer system using a USB-C cable.

New Laptop Battery Charging Tips

When people talk about new battery charging tips, they refer to mobile phones’ batteries. But this applies to laptop batteries as well. The following tips will help you understand the right process to charge a new laptop battery if you want to sustain its durability.

  • Don’t Overcharge Laptop Batteries

It is possible to damage a laptop battery from excessive charging. Some models of laptops do not have the feature of cutting off the supply of power to their batteries. Therefore, leaving your laptop in charge after attaining full charge, for some laptops, can result in overheating. As such, always unplug your computer once fully charged.

  • Avoid the “0%” Mark

It is advisable to keep your laptop battery between 40% and 80% before connecting it to power again. Sometimes, this can be impossible in an area without a power supply. However, you must always keep this in mind. Leaving your laptop’s battery to discharge completely will reduce its underlying lifespan.

  • Keep the Laptop in a Cool State

Whether or not the laptop is on a charge, this is an important aspect of sustaining the laptop battery’s lifespan. Be sure to keep the laptop on a hard surface, like a desk, when it is on charge. Also, ensure the cooling fan is properly working, as overheating can negatively affect the battery’s durability.
