Predator G5-793 charger voltage differences, which one is better for long-term use?

Hi there, I recently had to replace my Acer Predator G5-793 charger due to cable damage. The output of it was 19.5V 9.23A 180W.

I bought 2 replacement chargers from 2 different companies as I was in a rush to get one. While both look identical and supposedly have the same specs as above, one is outputting 19.05V and the other is outputting 19.83V when tested via multimeter. Would these still be alright to use in the longterm? I used the 19.05V one all day yesterday and it seemed okay but charged a bit slow. I just received the 19.83V one so havent tested yet. I dont want to try it without confirmation from someone who knows about this kind of thing as I am finding conflicting info online regarding overvoltage and undervoltage.

The power cable will always be connected if that matters as I never use battery anyway.

If they are alright to use, which one is likely better to use? The slightly over or under voltage one?

Any info would be amazing.
Thanks in advance!

Yes, either of those chargers will work fine. The input voltage is supposed to be a nominal 19.5V, but it's not critical. Here are the two power supplies Acer used on these:

As you can see, the second one is 19V, not 19.5V. The key is the connector size (7.4mm with a 5.1mm center hole, 11mm in length) and the power at 180W.

Hi, this is a 2016 model laptop, if you never replaced that battery do it now after 9 years it will have died. never mind the 1-volt adapter difference, the main thing is the plug pin size, check if you hear it click when the plug is fully inserted in the DC socket, and a good 100% charged battery for Windows10 Modern Standby to work properly.
