I mostly use external power banks on my cameras so that I don’t have to concern myself too much with battery life while recording. With that said my issue was with the gopro hero 5 that I recently purchased. I had to come up with a way to make the charge port area somewhat dust and splash proof especially since I mostly record while out on the water. Removing or leaving the charge port door open (or removed) just exposes too much to the outside elements so I set out to try and design something that would accomplish my goal and came up with what I think is a winning solution for me…
NOTE: This charge cord opening dimension was derived using the gopro charge cord for fitment.
The outer version of the cover mounts onto the existing opening of the cameras protective shell frame and snaps in place. The extra top portion of the cover itself is there just in case double sided tape was required to keep it mounted. The dust cover does not interfere with the mounting or removal of the camera from the protective shell regardless if the cameras charge port door is installed (closed and locked) or completely removed from the camera. The dust cover also adds a lot of additional support to the charge cable end itself when in use.
The inner version of the cover mounts on to the camera itself in place of the charge port door of the gopro prior to inserting the camera into its skeleton case.
You can use either the inner cover or the outer cover or both together.
