Usb-c to barrel connector adapter

[devout vessel]

Hey, I wanted to change to a single charger config but I’ve hit a problem.
I have an asus Vivobook with a 4.5x3.0mm barrel and want to go USBC. My laptop peaks at 120W which is supported with the included psu.
For something like this https://www.amazon.com/Cablecc-Female-4-53-0mm-Charge-Laptop/dp/B0832LT6GM/ref=mp_s_a_1_13?crid=EIREUZBUEUC5&keywords=usb+c+to+4.5mm+3.0+barrel&qid=1669559259&sprefix=usb+c+to+4.5mm+3.0+barrel%2Caps%2C144&sr=8-13
Where the tested limit is 100W, would it cause problems when the laptop asks for more power ? I’m not sure if I should buy this adapter, a PD adapter, or use a 100W usbc cable with an e-mark chip to make sure I don’t go over the limit.

I want to use an Anker 120W Brick, which is capped at 110W but should I buy a 140W USBC cable and not worry about it or a 100W in line with the adapter’s limit.

The laptop can't really ask for more power if the cable is managing the power for it. I'm unsure what happens if you plug a 140W cable into a 100W supply, it may depend on how the PD negotiation is programmed, it could just negotiate the minimum (100W), or it may just give up and not supply power. Note that I avoid using amazon grade equipment with anything I value.

Yeah true. I should always be careful but this adapter has 800 reviews. In theory with an anker adapter and cable, I should be pretty safe but anything can happen. There is also the fact that the lower threshold is 65W but my laptop uses only 30-50W when the battery is charged at idle. But it looks like people are still able to use it with lower power devices

A complicating factor is amazon's "equivalent merchandise" policy, which lets them ship an "equivalent" item from a closer warehouse. This can mean you pay for a genuine item from a reputable seller, the seller can ship a genuine item, and you still end up with a counterfeit.

But do you think there is a real risk of the adapter overheating or damaging my laptop ?

That I can't quantify, I'm just saying that I buy things elsewhere.
