Can I charge a phone with a 9v mains charger?

I've found this 'adaptive'  charger in a drawer which hasn't been used for many years. I was surprised to find that it states 5v - 9v for its only outlet, a 2.0 USB socket. I'm struggling to think of a Samsung tech product I've had that might have needed more than 5 volts. Maybe it's 5vDC on 110vAC and 9v on 230v?

I can't seem to get a close up shot of the barcode thingy as my 3-camera phone appears to have no such setting!

That is a phone charger. Phone chargers vary the current and voltage to deliver maximum power without needing a very thick cable. 

That would be an 18watt  Samsung charger. Most phones will charge at that rate.

Got one very similar, it was the charger supplied with a Galaxy A52s phone about 18 months ago.

This is what your barcode thingy says "GH44-02952A+R37J714LH31SE3"

that;s the Charging brick  that probably came with an S8 or S9 phone   as it;s  black , USB A and  AFC 

 adaptive fast charging   offers 9v @1.67 amps  over USB to  a suitable device to allow for 15 w charging  

if the connect a device  which doesn;t do AFC it will  fall back to the 5volt USB standards and offer upto to 2 amps at 5 volt
