Will The Samsung Fast Charge AC Charger 45W Charge a 2020 MacBook Pro at The Full Speed?

Hello OzB community,
I am thinking about getting the Samsung 45W fast charger from here and was wondering if it will charge a 2020 MacBook Pro 13 inch at its full potential? Has anyone had an experience with this charger and charging a MacBook Pro with it?
TIA

    No. You need 61W.

      What wattage will it charge the MacBook at then?
      Will it charge at 45W? Sorry I poorly worded the post, I meant to say if it will charge at the full wattage of the charger not the full potential of the macbook

        If you buy 45w then the PD will request 45w and deliver 45w.

          Thanks, that’s the answer I needed

            @jayboi: Just double check. Because my 96w MacBook charger can't super quick charge my phone. But that might be a charging standard thing. My monitor can charge my MacBook at 60w but I'll double check when I get home on whether it will deliver the full 60w.

              @No Username: I’ve read online that the 13 inch MacBook Pro can only charge at a max of 61W and it supports PD. So I just wanted to check here if people have had experiences with the charger and a MacBook pro, I’ve ordered as its pretty cheap at $34 and it supports PD.

                @jayboi: Just checked my laptop and it does indeed charge at full speed sort of. Charger is rated at 60W.

                    @jayboi: ⌘ + Space

                    Look for System Information

                    Go to Hardware > Power

                    Scroll to AC Charger Information

                      @No Username: The Samsung charger just arrived and I checked and it says charging at 45W thanks so much for your help. Looks like it’s working perfectly

    I have a cheap multi usb charger, with USB-C 18w PD and it charges my Macbook Pro 16" overnight. I was amazed that it worked… The one it came with is about 90w and Ive used a cheaper 60w PD from Amazon but having it work on the 18w was gobbsmacking and it also results in a cooler, slower recharge which makes for a longer battery life overall… Very happy

      Wow that’s an awesome idea, thanks for bringing that to light. I have a 27W PD blitzwolf USB c charger, I will use that for overnight charging now. Thanks so much for the tip!
