Learn how to charge a laptop without a charger using creative methods such as solar energy, power banks, and universal power adapters. Stay productive on the go
The main advantage of a laptop over a desktop PC is its autonomy. And you can charge the battery not only with a non-complete power supply. Read about the main alternatives in our article.
Alternative ways to charge your laptop;How to Charge a Laptop Without a Charger.
Via power bank
This method is only suitable for those laptops that support USB-C charging. In addition, the portable power bank itself must support Power Delivery, have an output voltage of 18 to 20 volts and a rated current of 2 amperes, and be at least 1.5 times larger in capacity than the discharged battery. Usually, this is enough to fill the battery by 70-80%.
Via USB Type-C adapter
Modern laptops can be charged via a USB Type-C adapter. Earlier versions of ports did not support enough voltage to power the device. But on current models, the USB 3.1 connector provides a current flow of up to 100 watts in both directions. This is enough to power the battery and continue working without any problems.
Via a universal charger
A universal power adapter is one of the best ways to charge a gadget if the original cable is broken or lost. It works like a standard adapter. Therefore, it is recommended to buy one in case of any excesses. The main thing is to make sure that the specific model includes the type of plug you need before buying it.
Through another laptop’s charger
It is quite possible to charge your laptop with a cable from another laptop, especially if you need it urgently. But it is important to consider that such a charger should fit the connector and give out similar power. Otherwise, the dead battery will remain empty, and the gadget will turn into a brick.
Via battery charging station
Mechanically, the method is similar to a power bank, but due to its greater capacity, it surpasses it in efficiency. However, there are several “Buts” here. Firstly, such devices are quite heavy and bulky. Secondly, for greater efficiency, you will need to take a solar panel. And thirdly, all this beauty costs a lot of money. It is up to you to decide whether it is worth it.
Through the auto inverter
The car inverter converts energy by power so that it can be connected to various devices, including a laptop. It is enough to connect the device to the car, and then put your device on charge. This is much more convenient and safer than connecting directly to the battery or through the cigarette lighter.
Through an electric generator
If you have a diesel or gasoline generator in your household, you can take a special adapter and put the laptop on charge. A universal charging adapter is also suitable for this. But it is worth noting that this is a very noisy and heavy option, and also with not the most pleasant exhaust.

Through a wind generator or solar battery
Solar panels and wind generators can help out in case of power outage. The main thing is that the operating voltage is suitable for the laptop battery. You will also need adapters and, possibly, an intermediate converter. There are also solar batteries that work as power banks.
How to properly charge a laptop battery
To ensure that your laptop battery lasts as long as possible and does not require replacement after a short period of time, you need to follow simple charging rules. They are the same for almost all models:
- Use only the original charging adapter;
- The methods described above should be used only as a last resort and not on a permanent basis;
- Never power the laptop directly;
- Make sure the charging cable, plug and connector are intact and in good condition;
- Make sure that the battery charge does not drop below 20% and never allow it to discharge completely;
- If the battery is removable, then when operating from the mains it can be pulled out of the case;
- Do not allow the battery to overheat and use a fan to cool it;
- Also, do not allow the battery to overcool, otherwise it will lose its working properties.
In addition, it is worth remembering that modern laptops do not require “swinging” from the charge-discharge cycle. They also refer to the fact that the laptop will be constantly connected to the network, since a special chip does not allow the battery to be recharged.
