Fujifilm XT-1 Third Party AC - Adapter

About six months ago In preparation for some Astrophotography I purchased a third party AC adapter.  I was being pre-emptive as my XT-1 was yet to be delivered.
Turns out it wasn’t needed as the exposure times required by this camera allowed the use of the internal battery, and a couple of spares.

With my old Pentax camera the long exposure required, 40 seconds plus, demanded external power as the shutter being held open for such a period would flatten the internal battery in no time.

I have to report though that upon testing it, it didn't work properly. Although the the box that emulates the battery looks to be the perfect size, it's not and as a result doesn’t make proper contact with the camera.
I fixed this simply with two small pieces of electrical tape placed in the corner where the battery door catch contacts the battery. After this it seems to work just fine.

Tapes a bit Crooked

On a tripod in a studio is a situation you may need one of these. If this problem happens to you, it's a simple fix.
Remember any kind of AC Adapter for the XT-1 will require that the battery door is left open so the cable can pass out, just make sure that this will work in your situation.
