I'm planning to hack in a camera (hopefully hns added the CSI solder pads..), so I could use a second "defective colour" case.
Uh, why would >2A be required? USB spec doesn't even allow >2A... you need USB-C for that, and Pyra doesn't have USB-C. But more importantly, I would hope idle power draw is well under even 500mA so a normal USB port can charge it.I don't have a single USB charger that is not lethal to use... And none at all that can supply the required > 2 A, those aren't even supplied with phones afaik.
