A small PD charger seems to be about 6-7cm square. One that charges a notebook at 65w costs abt $65.
Your notebook charger is about the same size, and has a usb port.
What's the advantage of buying a pd charger then? Lots of $$$ to do the same thing. No smaller.
Not with a 60w. Only if I pay 100 for a 90w or more!
In my case, a GaN PD charger is actually smaller than the brick that came with my laptop. Plus the associated cables are much less bulky. In fact, because my PD charger plus straight into a wall, one set of AC cables is completely removed from the equation.
My 65w charger cost $36 shipped. A genuine Lenovo one starts at $58, although of course, deals can be had, as well as generics.
Another thing is, I purchased the charger not to replace the brick that came with my laptop but to augment it. Prior to USB PD, I similarly had multiple bricks for my laptop. The stock brick (which is usually bigger) stays home, while a smaller, slimmer, travel brick goes with me on the road.
And finally, my current GaN PD charger is now the ONLY charger I bring when I travel. On it's own, it's capable of charging every device I bring. Whether or not I bring my laptop. Previously, when I travelled, I had a special multiport USB charger. I still have it and it still works, but the PD charger has enough ports on it and supplies enough energy that I can retire that one.
could you link which 65w charger you're using?
This is the one I purchased a few months back.

Amazon has quite a few very similar ones ranging from $45-55 depending on the number of ports.
I saw a 65w charger cost $36 but with 1 port. So it wouldn't replace my multiport USB charger. Ones I saw that could were about $80+. It seems a lot.
I have this: https://www.amazon.com.au/dp/B07YL3M9BN which I believe I bought for around $40, and this: https://www.ozbargain.com.au/node/617126 which I believe was about $35. Both charge my XPS15 at 65w (though only when it is the only connected device).

There's a 12% off coupon going on the 65w one at the moment you can use to grab it cheaper, comes up on the product page for me using the Amazon app right now. Just click "save 12%" and it will let you apply the coupon. Brings it down to around $50.
dang, the 65w wouldn't improve my built in so I'm not sure.
is it safe to buy the ali weird brands? or shoudl I keep with a few known brands?
I have two USB C chargers with 65w pd charging and neither cost me more than $40. The main reason I have multiple chargers is because i really like to have cables as hidden as possible (wired through conduits etc), which isn't entirely practical for a laptop unless you have multiple chargers or never charge it outside of one location.
My other reason is that my laptop has a 130w brick but charges (albeit slower) over a 65w charger, so I prefer to use that in times when I don't need it charged quickly as it is theoretically better for battery longevity, and it means I have a versatile type c cable always neatly wired into my desk, and another one neatly wired in near my bed. As said by a poster above, I would still have multiple chargers if it wasn't type c, but type c is far more practical as I can also plug my phone, or headphones, or a multitude of other things into it.
I wouldn't buy a PD wall charger for a laptop unless I lost the original charger.
But I would buy a portable PD charger. That's where it's at. Charging laptop from a portable battery hoo yah.
One less charging brick to bring when travelling - a break-or-make difference if all you have on you is a backpack (and/or going on a carry-on luggage only flight).
There's no compelling reason to get a USB-PD charger for your use case.
If you do need a second charger for some reason, I recommend as USB PD charger as it's likely to remain useful for a long time to come, across most notebook brands and many more devices apart from the notebook.
Right now I'm using a monitor with USB PD at work I can leave the charger at home and have the convenience of single cable for video, power and USB hub (the keyboard and mouse are plugged into the monitor).
The next version of USB PD will support up to 240 W so it should even support those high powered gaming notebooks.
I would like a PD so I can leave the original plugged into my bedside. And go outside with the PD. Tho to spend $100 cuz I'm lazy, I duno.
Faster charging?
