There are typically 3 things when connecting a device to power:
1. wall outlet
2. extension cord/phone charger
3. device being charged or powered
Each has watts/volts/amps labeled. With W/V/A, how do I determine if a system is safe or unsafe?

Engineer checking in… If the device, cord, and outlet are all in good working condition and there is no exposed wiring then you should be fine. However, if you’re unsure then get someone trained, like a licenced electrician, to inspect it for you.
If you’re trying to design your own circuit for some DIY project then I’m going to suggest that you dont unless you get some real training somewhere. There is no one number for what a “safe” voltage or current is.
