We bought a Rog Strix G531GT-AL324T and it came with a charging device with a brick. And I was wondering whether or not this brick acts like an AVR that maintains consistent power input. As well as if it helps when the electricity goes out.

Hi,
What do you mean a charging device with a “brick”?
Is it as per the image below, where the block above A is the “brick”?
(click on image to enlarge for better viewing)
If so it is just a power cable and an AC/DC adapter.
The “brick” is the adapter (or charger if you like) that converts the wall outlet’s AC power supply into a DC power supply which is suitable for the laptop.
I suppose you could say that it acts like an automatic voltage regulator (AVR) in that it maintains a constant and consistent voltage output level to the laptop, whilst varying the current to cope with the demands of the laptop at any point in time.
If the laptop is on and is connected to the adapter then if the power supply to the adapter is cut off then there is no output from the adapter and the laptop will continue to operate on its’ own internal battery until its’ charge runs out. Try not to let it discharge too far before switching off the laptop in the event of a prolonged power outage
There is no battery in the adapter to power the laptop in the event of a power failure.
If you wish to continue to externally power the laptop in the event of a power failure you need to connect the adapter to a UPS power supply - example only
If the adapter is left connected to the wall outlet after the power has been cut off unexpectedly, then when the power is restored the adapter will take the brunt of any possible power surge and may be damaged. It is advisable to disconnect the adapter from the wall outlet (and also the laptop) in the event of a power failure.
Hopefully this is of some help

thanks alot this perfectly answered my question
should I use AVR so that my adapter and laptop will be protected in times of power surge?
Not sure what you mean by AVR but if you mean a surge protector then it is always better to have the adapter connected to it as it will protect the laptop and the adapter from power surges.
A good quality one is one that indicates that it has operated when a power surge occurs usually by a LED light turning off indicating no power or perhaps a circuit breaker in the surge protector operating letting you know that a surge has occurred.
The cheaper ones do not indicate and while they might protect the first time after that they may not so unless they fail completely and there is no longer any power coming through them you think that you are being protected when you aren't if another power surge occurs.
Here is just one to show what I mean. this doesn't mean that you should get this particular one but read the features that it has. These features are what to look for in a surge protector when buying one.

Have you tried connecting a voltage meter to it an see if there is much fluctuation?

Simply put. Essentially the “brick” is an AC to DC Rectifier, which would classify as a regulator. Most AC/DC Transformers utilize a internal fuse where if something were to happen to the power it is going to take the blow verse the computer.
