Hi, does anyone have suggestions about external power solutions for the GH4, that can be bought from shops in Singapore (i.e. not online)? I am aware of the DMW-DCC12 decoupler and its accompanying DMW-AC10 AC adapter, but none of these seem to be available from any of the well-known camera shops in Singapore. Does anyone know if any shop sells these 2 items? The closest thing I saw was a 3rd-party DC decoupler for GH4 from Alan photo, but it's almost impossible to find an AC adapter that connects to it, and with the right output voltage.
