How may I find a charging port outdoors for my laptop?

There are many ways to find a charging port outdoors for your laptop. For example, one may find charging ports in cafes, although usually those are reserved for paying customers. It's not uncommon to pay for a cup of latte and charge your laptop at the same time. Charging ports are also commonly seen in public places, such as public libraries, city hall, and parks. Public transportation is another way to get your laptop charged, as many trains have charging ports near the seats.
