Anker Nano Portable Charger10,000 and it will fast charge your iPhone and it’s small

No special cable. Your 100W Anker cables should be fine. If that bank lacks 15V or 20V USB C PD, the Anker Nano Power Bank A1638 is a good handheld option at $59.99.

I have this one by Anker and it works great with my S2 since it has a retractable cable

HK Army sells both a barrel and mask mount (which can actually be bought as a combo). I’ve toyed around with both and each has their pro’s and con’s. Currently, I have a piece of athletic tape wrapped on my barrel to protect it from scratches where the mount is. Using an HK Army barrel mount. The camera is housed in this off-brand action mount. I was using Insta360’s action mount, but that mount was thinner and broke within a couple days of play. This off-brand has held up much better. What’s nice about this mount is that I can use a small 10,000mah portable charger (this one) and run an insta360 GoUltra charge base cable, this. So I can charge the camera in between points if I want to. That all fits in a small case (this one) that I toss in my gearbag before and after play. I keep a couple allen keys for the mounts in that lil case as well
