A traditional desktop computer can work with AC power that we use in our home. But after the invention of laptop computers, DC power usage increased particularly in computers.
First, let’s find the basic information on AC and DC currents.
AC means Alternating Current that we get power from the nearby transformer. It is the power for instant supply and usage for household appliances like fridges, fans, ACs, Washing machines, etc.
DC means Direct Current which is a stored form of alternating current. The power we get from batteries to cars, laptops, mobiles, torch lights, etc.
Unlike most electronic devices, laptops can work with both AC and DC power. The manufacturers make this possible for uninterruptible product usage. The laptop power adapters work with AC because it is the current one we use in our household.
Now, You don’t have a laptop charger with you? Is your laptop charger not working or you just lost it? Whatever the reason might be, you just need to know how to charge your laptop without a charger.
This page exactly tells you all the possible ways we have.
I suggest you use a quality charger for your laptop for a healthy battery life and to avoid hardware problems. You can use another charger of the same type or buy a new one.
If the situation demands and you particularly want to charge your laptop without a charger, then the following list will help you.
Use Power Bank to Charge Your Laptop
In general, power banks are used to charge mobile phones. But when you want to charge your laptop using a power bank make sure it has a high DC power capacity.
The battery power is measured in watts or mAh. In a typical mobile phone, we have a 4000 mAh powered battery. And its backup charger (power bank) capacity is 10 to 15 000 mAh.
The laptop battery capacity is high when compared to the mobile. So we need more power from the source like power banks. That’s why I recommend at least 25000 mAh is good for power banks to charge laptops.
You can Charge through the Type-C Port
To use the type-C port on your laptop for charging, your laptop must have the one itself.
We need a device almost like a power bank called a power delivery charger. It stores current just like power banks do and we can carry them anywhere. That’s why they are suggestible to use to charge your laptop if necessary.
However, it is not advisable to connect type-C from any other electronic device to your laptop just for the sake of power because if there is no adapter to control power, then there might be a power surge between the devices.
In that case, your laptop might be damaged. That’s a risk I want you to avoid.
Charge Your Laptop With HDMI
In general, the HDMI port is for data or signal transferring. But in some worst cases, an HDMI port is useful for charging a laptop.
Compared to other methods, charging via HDMI port is not effective and means very slow charging. This is just because the HDMI port is not designed for power transmission like power adapters.
If you want to charge your laptop using the HDMI port just follow the steps listed below.
- Take the HDMI cable that is new and working
- Connect one end to the laptop and the other end to the TV or monitor
- Just give some time to charge along with processing data through HDMI cable
- Remember the charging speed is much lower than you expected. So you need to wait for a long time to find out whether your laptop is getting charged or not.
Also, make sure your laptop is compatible with this process to charge. Because not all laptops can take charge through HDMI cables.
Reverse Charge From Mobile to Laptop
These days mobile phones have high battery life like 4000, 5000, 6000 and even more mAhs too. But not all mobiles support the reverse charging feature. Make sure of it.
Just visit the company’s official website to find out whether your mobile has a reverse charging feature or not.
If the feature exists, then take a common port cable (type-C in most cases) and charge to your laptop from your phone.

Use a Car Charger to Charge
Do you have a car charger like your laptop charger? Yes, you can charge your laptop too with it because both the car battery and laptop battery are working with DC currents.
Just plug in the car charger to charge your car and while the car is charging take the USB type-C cable and put it in your laptop. If everything goes well, then the laptop will get charged.
Universal Adapter Helps to Charge Laptop
A universal power adapter undoubtedly helps to charge your laptop. But most of us don’t carry universal power adapters because of price and less accessibility.
If you have a universal power adapter, then good, use it to charge your laptop.

Use Solar Charger to Charge Laptop
Solar power is charged in DC mode. If you have a portable solar charger, use it to charge your laptop if you don’t have your laptop’s charger.
Making sure how much current is passing to your laptop is important because of any prevention from power surge damages.
Conclusion
These are the list of possible ways to charge a laptop without a charger. However, I want you to use your laptop’s company power adapter instead of all these temporary tricks.
All the above methods are less effective when compared to charging your laptop with its own power adapter. Just in case your power is damaged or not working, then buy a new one instead of applying all these methods. It helps to keep your laptop’s battery healthy.
