The device I showed is wired to 12v and it converts it internally to 5v you just drill a 1 1/8 inch hole

Should probably watch how much the usb plug pushes out. I had a dash cam that had a plug at 1a. It broke so I plugged it into a 2.1a and fried the battery in the dash cam. It was a few years old so it could’ve been a coincidence. But there is also such a thing as overcharging too, assuming if the usb plug doesn’t have any circuitry protection or whatever.

The problem was almost certainly in the charging circuit of your camera, not in the USB adapter. Batteries, power supplies, and transformers cannot "push" current. Rather, they can only provide the current drawn by connected devices based two values: their operating voltage, and the resistance present in the circuit. Ohm's law describes this as I = V / R.
