Is the output voltage, the volts seen by the end product, really 42 volts? Are there any poe injectors that provided 5v poe?

It will deliver up to 48 volts - if you need 5 volts - please see item B019BLMWY0 here on Amazon

does power supply come with the injector?

You just need a power cord - C13 type - $1 at a goodwill store or $3 on Amazon B003MGB0IK

What is the difference of this item from Phihong model 722442?

Not absolute sure but may first thought would be wattage!
