Either one should be safe. Both list 5v3a however neither have 9v2a so it could be just slightly slower than stock but definitely faster than wireless or an old 5v2a charger.

Just make sure you have a USB-C complaint cable and you'll be fine.
As long as the voltage is correct, you can send devices more watts than they require. All electrical devices only draw the watts they need. So if your charger supplies 100 watts, but the phone only needs 5 watts, it will only use 5 watts and be perfectly safe.

It seems every cable I buy from Amazon is one of those
Any wall charger support PD. I have wall charger 27W but not work good with the Pixel not charge fast

The last 3 pixel models have all had "USB-C complaint cable" issues with fastboot...
Sorry I couldn't help myself. Lol

Was there another issue besides fastboot not being reconogized when using certain cables and charging safety etc?
I got an Anker USB-C PD 10k watt charger for Christmas. It seems to charge my phone multiple times faster than the wall charger included with the phone. Is this due to the PD protocol? If so, could I expect a PD wall charger to do the same?
Sorry, seems dumb but wasn't sure if something else factored in
Were you using your device while it was charging? As that could have an effect on your device's recharge time.

If you are using the original N9 charger with adaptive fast charging, then the max rate is 15W, the same as via any PD charger.
Observed differences could be because of screen on, battery level, and temperature. Or could also be a worn out cable.

Thx. 15w is max the Note 9 can handle?
Is Realme X2 Pro compatible with qc 2.0/3.0?
I´m using an Aukey charger qc2.0, and when it reaches 75% aprox, it stops charging.
qc 2.0 uses 12V, 9V, 5V
I´ve made some troubleshooting, using a safety usb tester (V, A, W, etc.) and I discovered that when changing from 9V to 5V charging mode, it freezes!! and stops charging. I started at 30% battery level, charging at 9V 1.9A (17W), and reaching 75%... Intensity dropped down to nearly 0A... was no charging... I unplugged it, wait 1 min, plug it again, and it started charging again, but at 5V 1.33A (7W)...
with other mobile phones and same charger (Aukey) it changes from 9V to 5V without stoping, so I am worry if it is a problem of my Realme unit...
Can anyone confirm this?¿?¿?
Thanks in advance,
Qualcomm list doesn't include realme
https://www.qualcomm.com/documents/quick-charge-device-list
But I'm my experience should be, I'm using a zmi car charger and Xiaomi 6 port charger with QC and in both charges rapidly
At work I'm using a leeco charger, and stop charging at +/- 70%
I don't know why

There must be a compatibility problem,
Maybe, if you unpluge and plug it again it will charge up to 100% (it works for me)
Let´s see if it can be solved in next software update, I will try to contact Realme support to let them know.
My charger at work also supports QC 3.0 (not oficially, LeEco Model EQ-248CN).

Bit late to the party...
My phone does work fine with QC. Charges at 9V2.1A until about 60-70%, then drops to 5V2.1A. At about 90% it drops to 5V0.6A until 100%.
My QC3 charger from Aukey also faces this issue. Charging to 80% and then it stops... Still the same after update to c27...
This phone supports 21w charging, but it is only shipped with an 18W charger. (This charger seem to be able to give out 5V, 9 V (2A) and 12V (1.5A).)
Anyone have information on what version of USB-PD the phone supports? And what voltage is used to obtain 21w?
Has anyone got 21W charging working? As not all higher wattage usb-pd charges may support the 21W mode that this phone needs.
Well I can tell you do not use anything above Sony's recommended charging °W because anything above that - even with PD -- the device will intensely heat up.

Sony report 21W charging. So I'm not asking to go above Whats recommended.
I am asking more about the actual charging methodology, as the usb-pd system can be a bit complicated. And even a 45W charger may not correctly 'handshake' at 21w unless it's got the right voltage to offer.
Anyone?
No one has tried using a higher wattage PD charger?

My Xiaomi 30W 1A1C charger (which supports USB PD 2.0 over the C port I believe) negotiates 7V/3A to hit the 21W.

Nice. That is an interesting combination. I thought it might do it at higher voltage.
How are you measuring it? I'm thinking of getting a usb measuring display.

Me too, I thought it'd be doing 12V/1.8A or something but 7V/3A makes sense. Definitely should make sure the cable is quality enough to support 3A. As an aside, the phone charges at 5V/1.5A for all non USB-PD compliant chargers.
I measured with a super cheap USB C meter that I've been sticking into random chargers for curiosity sake. Highly recommended :laugh:
Ok, ordered an Usb pd 3.0 charger today, the Arcanite one. As it also has a PPS option.
Also ordered as usb c power meter.
Let's see if it does the same voltage combination with this charger.
I just looked more into the USB-PD spec and I believe you'd need a PD3.0 compatible charger to hit the 21W since the charger needs to support PPS to hit 7V/3A. Otherwise I'm assuming it would negotiate to 5V/3A or 9V/2A if the charger doesn't have a 7V step.
So got a charger with PPS support (a USB-PD 3.0) an up to 30w charging. An Anker USB c to c cable with 60W support.
And using a satechi voltage / current measuring device.
But something isn't correct. It could be the usb-c voltage measure.
Using the supplied 18W charger, it's displaying 5.27V, 2.78A. that's roughly 15W. ( Picture attached).
Using the new 30W charger, it's displaying 6.44V, 2.77A. that's roughly 18W. ( Picture attached).
Still need to do more testing, not sure why I'm getting these readings. A bit below what I was expecting.

What battery % is your phone at? You also have to remember that the closer the phone is to 100%, the charging speed will slow down.
I have an Anker 30W charger and can charge at speeds of at least 3500 mAh (based on Ampere reading).
The battery was around 35%. Yes you are right once it got over 50% the charging rate does show down a bit.
Also the Ampere app was displaying 3600 or 3500 as the current. But even if we calculate that, that's only about 18W. But that app isn't very good at measuring charging voltage or current.
The charger's specifications are attached below,
Actually, did anybody find a 21W charger compliant with our device??? (I mean really delivering 21W...)
Edit:
I've ordered the Samsung Ultra Fast Charge 25W (ref: EP-TA800XBEGWW)
It is PD 3.0 PPS and delivers 3.3-5.9V at 3A or 3.3-11.0V at 2.25A.
I hope that will work...

I have the Samsung EP-TA800 25W charger from a Samsung Galaxy A71 5G. On low battery with my USB tester, I measured 22W (9V/2.5A) when charging my A71 but only 15W (5.5V/2.7A) when charging my Xperia 1 ii. Were you able to do better with this Samsung charger?
In fact, I have been testing all my PD chargers (about a dozen in total -- I might have a problem!), and none has been able to charge my Xperia 1 ii at more than 18W. That's certainly decent, but it would be nice to get the 21W that the hardware is capable of.

I've finished my tests.
Both Sony charger 18W and Samsung EP-TA800 25W charger take 37 mn to charge from 20% to 70%. So, the extra power of the EP-TA800 cannot be used by our device, it does not provide the correct electrical intensity...
Finally, I've ordered the ARCANITE Premium PD 3.0 QC4 PPS 30W charger as mentionned above.
I've received the ARCANITE Premium PD 3.0 QC4 PPS 30W charger and I've done the tests.
To charge from 20% to 70%, the Sony charge takes 37 mn and the ARCANITE charger takes 36 mn (tests done in aiplane mode).
The small difference occurs below 50%.

Thanks for the update. It seems like the ARCANITE might not be delivering the 21W as hoped.
I also ordered yet another charger, the Baseus BS-C915, which allegedly supports PPS. The PPS designation appears in some pictures, but the specifications describe only a range of voltages (3.3-11V @ 3A).
With the Baseus, I get just under 18W (6.6V @ 2.7A) when charging my Xperia 1 ii. It's kind of strange that Sony claims 21W charging but doesn't include a 21W charger and doesn't even provide the specs for one!
Are there any other devices with the same power output? I have various Oneplus chargers, and a couple of Quick charge 3.0, but would like a spare fast charger.

You can buy the xiaomi 27W QC4 charger it does 27-35W
realme x2 pro has 50W, so something there shud fit
I've tried various chargers but the SOC was >85% so it wasn't a proper test. With most charger (QC or PD) I've gotten 15W, including with my 65W PD laptop charger. With the original charger I got 20-22W. If it's important to check the power, I can wait until it's discharged and redo the tests, which I plan to do anyway.
For travelling, I find it a lot more useful to have the 36W (18W QC + 18W PD?) cheap Amazon charger with 2xUSB-A and 1xUSB-C, which has the same size as the original charger: https://smile.amazon.de/gp/product/B07WFDTJFR/
Let us know how you get on. I tried my Samsung 25w charger, Pixel 3 charger and the Motorola 18w charger. All of them charge at 12-18w only. Stock charger goes to around 27w
I've now tried all the chargers and powerbanks that I have, QC3 or PD. All of them cap out at 16W, even though they can deliver more. I got the original one to charge with 30W (at 60% SOC).
The original charger is marked QC3 but they are probably not following the standard.
From my understanding the Snapdragon 732g has Quick Charge 4+ support doesn't it ?

Yes, i've noticed the same. Around 27w max. Today i was charging my phone and observing the batt temperature. Kinda obvious, but the hotter the battery gets, the lower charging power it will deliver. Here in Brazil the temp this week is being around 36-42°C, so i put the phone over a bar of artificial ice. As the batt temp went under 35°C, the resultant "charging current" went to around 5500-6000mA. Doing the math, it was possible to arrive at the 27w result. (~4,5V x 6 = 27w).
When the batt temp was near 38~39°C, charging was down to 2000-2800mA (resulting to around 10-12w).
I also found something strange, it wasn't able to show the charging percentage with 2 decimals, as shown in this video:

For me GAN 65W chargers (Baseus) are good and universal quick chargers.
I have made a quick test in the thread Chargers and Charging speed
