So I want some cheap 3.3v fixed output buck converters and I found this, but I don't understand their description of how the voltage works, do you?
They show on the back 3.3v then 5v under that, then 9v and 12v under that????
The product:

I attached the pertinent image.
Bonus: I also see sometimes buck converters on Amazon give two input voltages??? Like:
5v Regulator, DROK 5pcs Mini Voltage Reducer DC 4.5-24V 12V 24V Step Down to 5V Buck Converter Board 3A Volt Step-Down Transformer Power Supply Module
The output should be 5v, but it gives 3 input voltages? (4.5-24v) (12v) (24v) that makes no sense.
Thanks in advance.
