Ask HN: It's 1954, how do you charge a cell phone?

Someone walks into your shop with a USB-C Android mobile smart phone. It has 45% battery life, but even offline you can see amazing things in the apps. Not knowing the USB-C pinout, how could you charge it with contemporary equipment, without risking burning it out?

Open the phone. Take the battery out of the phone and test the output. Replace the battery with 1954 tech. Don't bother with the USB-C port.
