Max Wattage for Thunderbolt 3 Power Delivery IdeaPad 720s 15"

I'm thinking about picking up a USB-C charger for my Lenovo IdeaPad 15".  I see a range of wattage options and I was thinking of going for a 90W charger so that I could bring that with me on the go and leave the Slim Tip at home.  Is there a maximum wattage the Lenovo 720s is willing to accept from the Thunderbolt USB-C port?

So I currently have the Lenovo USB-C Dock (90W) and the Thunderbolt Dock (135W) and both DO NOT charge your laptop via USB-C cable. I've updated the laptop system, dock firmware and version, etc. but no luck yet. I'm investigating other USB-C cable (active vs passive) that can deliver 100W power. I will update here once I find out.

Sorry for bumping up this topic again. I have recently purchase the 720S-15IKB.

Have anyone gotten the Thunder Bolt port to charge from anything yet?

I'm still hopelessly searching the web for the Power Delivery option for this model.
