Best way to charge laptop on an airplane while using thunderbolt display out? (2023 Zephyrus G14)

[Atheos]

Hello all, so I have a Zephyrus G14 I travel with, I use it in conjunction with my Xreal air 2 pro. Now without them, normally I'll use some sort of combination of battery banks, and or my 100W USB C charger to plug into the airplane seat ( I think it only delivers 80W or so) 

 

The power brick it came with definitely will not work on airplane plugs. The problem now is this laptop only has one thunderbolt port, so how can I charge it and display out at the same time?

 

I ordered a DC:USB C adapter, but it may not work if the DC port doesn't like sub 100W power delivery.

 

Anyone have any suggestions? 

 

Thanks!
