Why do you recommend formatting the 128GB-Card not in the camera?
I use serveral 128GB-Card (Samsung, SanDisk, Toshiba) which work great. They are formattet in the camera without any problems.
So why not use the camera option?
Power Source is a simple 10.000mAh USB power bank. The microphone is a cheap mono version. Git2 does only record mono. I use an extra big windshield, because of windy situations while pedaling.

You have to buy a cheap microphone with 3,5mm connctor.
I did so.

I am using different batterys with 950mAh, 1050mAh or 1100mAh. All of them works good. I´m using my cam not as a dashcam. I think it´s just designed as actioncam.
