Wall Charger For Clip Zip

Thanks, right I understood that part.

My question is around the voltage being put out by my charger:

My charger plug label specs note “Output voltage: 4.5V - 9.5V”.

Which output voltage number (4.5V, 9.5V something in between) is applicable when using this charger in the US (110V outlet)?

If it is 4.5V or 5V I should be okay or does it need to be exactly 5V?

The chargersI found online for the Clip Zip (includng generic) are 5V.

I ordered one charger set (wall plus car plus detachable USB cable) that is 5V  plus a sepaate USB cable for another location.

In the meantime I was hoping to use the charger noted above labeled 4.5V - 9.5V for output, so I need guidance to ensure it is safe (i.e. 5V and not 9.5V e.g.).

Thanks for any help!
