Depending on the wattage of the charger you are using, your computer might charge a little slower than usual, but most USB-C chargers should be able to keep up with your computer’s power demands.
USB-A ports are rectangular and often have a three-pronged symbol next to them. USB-C ports are small and ovular. AC ports look the same as the outlets you find in the walls of buildings. DC ports are small and circular with a single prong in the middle.
Generally, universal power adapters tend to work with Windows computers that have circular charging ports.
While it is generally safe to use a high quality third party power adapter for your laptop, it is always safest to use a charger from the manufacturer, so consider using the included charger if possible.
You could also use a power inverter, but they are much clunkier and can be significantly more expensive than an adapter.
