I always carry a USB-C Power Delivery charger and a 4-inch USB-C to Micro B adapter (as well as a Type C cable, obviously). That way I can charge basically anything. I like the 30W one from Anker that has both the Type C with PD and a Type A port. I also like having the C to Micro B because I can charge my headset from my phone and that's priceless.
Damn, even I don't carry an iFixit-type kit. You go hard.
