Charging Microsoft Surface Pro 9 via the USB port
Hello,
One of the biggest advantages of using the Surface Pro 9 was that I didn't have to carry the charger with me. However, recently I have noticed the charge doesn't last as much as I want to. I do have a car charger that I can use in my car. I can also carry a small wall charger. I have this power bank https://www.amazon.com/gp/product/B083SD4DQN but it has the old USB-A ports and this doesn't charge the surface. I tried a wall charger and that also doesn't work. I was wondering do I need a specialized USB cable, or specialized power bank to charge the surface?

Basically, you'll need a USB-C power supply. The wall charger you tried likely isn't powerful enough, or doesn't output the right voltage/current needed by the Surface Pro 9. A power bank with USB-C output will likely work better, but it's always a good idea to check the output specs of the power bank to make sure it's compatible with the Surface Pro 9. The Amazon link you provided doesn't have any information on the output, which is why it's not working. You may want to look for a power bank that specifies its output, or look for one with a dedicated USB-C port.
