The last time I travelled overnight, I carried my SC62 (not the sc62w because I might cry if I lost it) and my DQG Slim AA Ti, plus a small USB single-cell Li-Ion charger. The Slim AA looks better if I have to appear more formal, and it can also use AA in a pinch (though I carry it with 14500). Empty spare cell holder is packed somewhere - they’re basically disposable to me at this point, I have so many, and I can safely store cells there if needed.
Depending where and how I’m traveling I generally have something simple like a convoy S2+ as its cost effective and does the job and not a total loss if it goes missing and as of recently a nitecore Tiki thats been attached to my keys.
I air travel with a SK68 and a pocket edc (DQG tiny aa) typically, camping is a different story, thrower (wurkkos ts30s), flooder (sp36), headlamp (sk40 or HD20) and something small for pocket (varies)
