If you read my post, I said I have that one, that I am looking for a longer cable or C extension that will work with it, since to get the 135W I need to use the usb c to square cable.

As that may not be viable, I may just get this instead, with a 10' cable that supports 140W+. https://www.amazon.com/gp/product/B0B79JGV2F/ref=ox_sc_act_title_1?smid=A11WFHPT0BDBVK&th=1

I have a gen 8 legion, which claims to support USB PD3.1 140W. So I imagine that would work. The official Legion 140W charger only does 140W if on 220V, where as I will be on 110V. So thinking that Amazon one may fit the bill.

I've got one of these right now and it works well. It's currently $53, but the price changes constantly. https://www.amazon.com/dp/B0B79JGV2F Soon all the EPR stuff will be a lot cheaper, so you might want to hold off unless 10 vs 3 second heat up really matters to you.
