If it has a USB shaped hole it's 5V.
The amperage rating on the charger determines how fast it will charge whatever you're putting on it.
If you take a teeny little 1A or whatever charger and try to charge your iPad it will work, but you're going to be waiting forever.
A bigger, 2.4A or 4A more robust charger will charge your stuff faster, and won't hurt anything. It is just capable of providing more.

Right you are! Al my USB cubes say 5V, except the Apple one, which has a USB-C port and four different voltages printed on it. The inescapable conclusion here is that I am overthinking again.
