I have a ROG Ally X, and I play with it plugged in to the wall 90% of the time. The rest of the time, unless I'm just away from the wall for 90 seconds while I'm letting my dogs out or something, I play with it plugged in to a battery pack, because I don't want to be using the device at less than the full power it's capable of (I use these battery packs, which don't require an extra cable; I keep three of them in my laptop bag): https://www.amazon.com/Anker-Portable-Multi-Device-Charging-Retractable/dp/B0DCBB2YTR/ref=sr_1_3?th=1

Also, I never travel with this to charge it up again. https://a.co/d/0acGujwr

It's pricy, but something like this or this would be your best bet.

I have used my air sense 11 cpap on an airplane with the following hardware. Works great. FLGAN 20V PD USB-C Power Supply https://www.amazon.com/dp/B0BV1J88GV?ref=ppx_pop_mob_ap_share Anker Laptop Power Bank https://www.amazon.com/dp/B0DCBB2YTR?ref=ppx_pop_mob_ap_share

Id stick with Anker here. The Anker Laptop Power Bank 25K 165W fits your 20K to 50K range and has enough USB C output for camping electronics. If you need AC outlets, jump to a small power station instead.
