I'm wanting to buy a Xiamoi Pocophone but they don't make australian phone chargers so is it safe to just use the Samsung type-c charger? I read so many articles online that to always use genuine chargers cause it'll make the battery have a longer life span cause non-genuine chargers will just make phone battery decrease life quicker. I don't really know if that's true…
Safe to use non-genuine phone chargers?

I think it is only the cable that matters the plug makes no difference and if the cable is by a trusted manufacturer you should be fine.
I can't imagine a Samsung charger would be worse than a Xiaomi one.
Also - it's all standardized - USB-PD is USB-PD. Interoperability is one of the main points of having a standard (USB Type-C).
lol, tell that to Apple. haha…..
Or Nintendo, or Google when it comes to audio, or… yeah. USB-C is a wreck of a standard. But Xiaomi and Samsung (so far as I know) haven't pulled any shenanigans with respect to wired charging.
Samsung has pulled a few shenanigans. With their USB-C which uses Qualcomm QuickCharge instead of PD. Nothing major though.
No, not true. It's fine.
Sigh the blanket statement here.
Yes using a none genuine charger can ruin your battery a none genuine charger can input to much current or voltage and degrade the battery. What if the none genuine charger used output 240v by way of a fault? Yes this can happen with a genuine charger also but it is more unlikely. Do some research and find a charger that is safe.
A none genuine charger can also use the wrong algorithm to charge the battery causing issues. Even ending a charge cycle with to high a current can shorten a lithium life span.To much current from USB 3 was killing the LG motherboards and causing boot loops.
Ok but what about a non-genuine charger?
My spell check bad probably should have joined the words.
I accept your apology

What?!
The phone does this, not the charger.
Nope the phone activates the QC/fast charge sequence that is all. The charger outputs the correct charge current and voltage. A charger can force power into a phone no problem.
I don't think you read his question, he's asking if it's safe for him to use his Samsung charger on his Xiamoi phone, which will be perfectly fine as Samsung make decent chargers.
He's not asking if his $2 no name charger from eBay will be safe, which we all know is a risk.
Read the first replies i am answering them. Also heaps of Samsung charger are fakes.
You're completely wrong.
Yes using a none genuine charger can ruin your battery a none genuine charger can input to much current or voltage and degrade the battery.
This shows you have no understanding of basic high school electronics.
Let's discuss the (electrical) current situation first. How does a charger "input" too much current to a phone? This statement makes zero sense. The phone will simply draw the amount of current it needs. The USB standard is generally 5V. Once upon a time, devices would draw 500mA, but today, it's common for devices to draw up to 2A. They will only do this if the charger signals that it supports it. This is to protect the charger, since if the phone draws too much current, it could potentially overheat (and burn) the charger.
Now, the voltage situation. The USB standard is 5V. This is what all USB chargers will use unless the handshake with the device indicates that they both support a higher voltage (e.g. USB PD 2.0 will also support 12V or 20V). Using a higher voltage is a more efficient way of getting electricity to the device as you can supply the same amount of power with a lower current. No charger will force 12V or 20V unless the devices has requested it.
If it really is the case that chargers will always force higher voltages, then plugging in an old phone which will only take 5V will make it explode. There are chargers that will charge too slow, but none that will charge too fast.
Not all devices are current limiting? Some devices draw more current than they need? Why where the LG mother boards frying from bad chargers? The battery may be able to handle 4amps fast charge but the socket or motherboards can not or any other component? Traces are only built to handle so much current. If the charger is not regulated properly it will input to much current into the phone. You can also force current and voltage into a device. To high a voltage can cause an excess of current.
You should hook a LED up to a circuit and tell me it will limit current it will burn up when it can longer dissipate the heat.
So much ignorance, you don't even know what you're saying.
Not all devices are current limiting?
What is current limiting?
Some devices draw more current than they need?
Then it will draw more current than it needs from any charger that is able to supply it.
Why where the LG mother boards frying from bad chargers?
Evidence? Looks like a pretty isolated case.
The battery may be able to handle 4amps fast charge but the socket or motherboards can not or any other component?
Then the phone should not request quick charge. Again, this has nothing to do with the charger.
If the charger is not regulated properly it will input to much current into the phone.
This statement makes zero sense. Current is not "supplied" or "input", current is drawn. If a phone tries to draw too much current from a charger, the charger will either 1) shut off due to overheat protection, or 2) go up in flames.
Also, there is no such thing as "inputting" current, current is a rate, not a measure of quantity. To say that too much current is input is akin to saying your car inputs too much speed. It doesn't make sense with respect to what current is (a measure of charge passing through a point per second).
To high a voltage can cause an excess of current.
Find me a USB charger that will output something other than 5V without handshake.
You should hook a LED up to a circuit and tell me it will limit current it will burn up when it can longer dissipate the heat.
Please, save me from your uneducated rant. I teach these things for a living, I've also contributed to a high school level physics textbook. I know what I'm talking about. If I plug my phone into a 100V DC power source, it might damage something (phones generally have very good overvoltage protections, but ignoring that), it has nothing to do with what USB chargers supply.
Again, find me a USB charger that supplies more than 5V without a handshake from the phone to use a different specification.
Xiamoi ???
I know a genuine Magnetbox, Panaphonic, & Sorny when I see one …
USB chargers is actually just a power supply unit. It is your phone's internal circuitry board that handles the charging of the battery. Any voltage surge from a cheap charger can damage your phone. More importantly using cheap chargers also has its risks like this
Would anyone happen to know if the Samsung Fast Charging Travel Adapter can fast charge a non-samsung phone?
Genuine vs non-genuine is more around the safety features. Often non-genuine ones are very cheap chinese made devices which in order to make it as cheap (and nasty) as possible they would remove components such as the ones for regulating voltage or any smart chips which tell it to switch off charging.
If you want to go non-genuine then you should get one which is made by a reputable company, like Blitzwolf, Tronsmart, Aukey etc.
don't just go to eBay and search "USB-PD Charger" then sort by price and get the cheapest one. One day it may just cost you your life or your phone's life.Last time I used a cheap non genuine cable from ebay, it turned by phone into a paper weight.
I have never read that using a non original charger shortens the battery life of a phone
