Yes. Provided that your laptop supports usb charging.

The USB standard provides a maximum power output of 4.5 watts (5 volts, 900mA) for USB 2.0, and 7.5 watts (5 volts, 1.5A) for USB 3.0, this is not enough power to charge a laptop battery, as most laptops require a minimum of 60 watts to charge.

However, you can use a USB Type-C port with Power delivery feature, that can provide up to 100W, which can charge the laptops or even power some laptops.

Using a USB-C port to charge laptops is becoming more popular. Many newer laptops are now being equipped with USB-C ports which support Power Delivery (PD), allowing for faster charging and improved power management. USB-C is also a more versatile and convenient charging solution, as it can be used to charge not only laptops, but also smartphones, tablets, and other devices that support USB-C charging.

The USB-C standard is also smaller and reversible, so it's easier to plug in, and it allows for other features such as video and data transfer, it has become an attractive choice for laptop manufacturers.

Some new models of laptops, ultralights, or convertibles are shipping only with the USB-C port and no traditional power adapter port. so it's becoming a trend.

It's worth mentioning that some older laptops that were built before USB-C popularity, might not have USB-C ports and therefore have to rely on their original charger to charge.
