Android Phone/Tablet charging from same adapter?

I have Samsung S23 ( 25W ) and Xiaomi Pad 6 ( 33W). It is a hassle to use two separate chargers.
Can I just go ahead and charge my phone with the same charger of 33W? Would it damage my phone?
 
No it wouldn't damage the phone, the device and the charger always does a handshake before upgrading to a higher voltage.

The supported voltage outputs seem slightly different for Samsung 25w vs Xiaomi 33w, so would need to check whether the fast charging works as expected. If the device and charge cannot come to a supported fast charging protocol, it will default to the regular 5V.

In short, it wouldn't cause any damage, but it may not always charge at the max possible rate.

this is valid for new gen devices but incase any standardized fast charger is used with old gen devices they apparanty start giving issue with battery backup or device overheating while charging or worst is damaging battery or damage charge circuit. learned it the hard way when i used a fast charger with ps4 controller

This is what worries me. But as you said, new gen devices don't have much to worry.

That is reassuring. Thanks for being so elaborate. I suppose this is going to be fine.
 
@dktechsavvy That’s interesting, which power adapter was it? Over the years, I’ve not seen any such issues.
 
i was using samsung fast charger, will post the image later in the evening so we can see multiple voltage values supported by the adaptor.
 
I have a Samsung phone/tablet, an iPhone 15 and iPad. Since they all have a USB C port, I just use any charger that's available.
I've been monitoring the iPhone battery health all year, and it does not seem to have been impacted due to this.
 
Have used Thinkpad T580's usb-c charger on low end standby Samsung A03 phone, working fine for years.
 
You can do that, and it will be fine as long as your charges are reasonable. One downside is that the speed might be slightly slower than usual.
