If you wonder how to charge your laptop by USB, we must tell you that it is possible. We recommend that you enter to know how not to do it.
About 5 years ago, the possibility of charging the laptop via USB was unfeasible due to voltage issues. Today, we see many Mac and Windows laptops that are charged through the USB-C port, so many are wondering if it is possible. We know that some of you are here because your power port has broken, so you are looking for a solution. Next, we tell you how.
Charge your laptop with HDMI or USB-C
Yes, it is possible to charge the laptop through the USB-C port because it provides the necessary power that our laptop demands to be charged. Before, with USB 2.0, it was not viable, because the PC requires more voltage than this port offers (between 15 and 20 volts). So, if you do not have USB-C in your laptop, you can purchase a DC-DC converter to modify the voltage from 5 volts to 19.
Advantages Of HDMI or USB Type-C port
First of all, it is a universal port, so we can connect a HUB or adapter that allows us to transform that port into 1 x HDMI, 4 x USB, and even 1 x RJ45. So manufacturers save costs and space on the sides of the notebook in exchange for versatility.
Second, we can charge our laptop through a power bank or with another charger that is not the official power adapter. This makes things much easier if the power adapter breaks, which should not be a problem because it is easy to acquire a universal one. But beware, not all power banks allow them.
Third, we can use different USB-C laptop chargers, although it is not recommended, nor is it a categorical rule. There are ports of this type that are not prepared to charge the laptop, so check what the manufacturer indicates on its website to make sure of it.
Finally, a USB-C charger is very cheap, so we rest from the concerns that arose 5 or more years ago with laptop chargers.
In conclusion, you cannot charge the laptop via USB 2.0 or 3.0 due to voltage differences. On the other hand, you can do it through a USB-C port.
