This article is about creating a 12V car-adapter for the Fujifilm X-T1 camera for longtime-exposures and time-lapses. – Recently I started to record a time-lapse with my Fujifilm X-T1. Everything was prepared. Then, after quite some time I went back to the camera to check the result. Bad news, the battery died in the meantime and the time-lapse was not completed. In order to address this problem I thought about having a different power supply for my X-T1. More precisely I thought about hooking the camera up to the 12V vehicle power or directly to a 12V car battery.

The solution turned out to be quite simple and inexpensive. All you need is:

1.) A variable DC-DC Buck Converter (this one) for about 13€. The camera needs 7.2V and about 300mA. So this converter is probably oversized but I wanted to make sure that the converter is not a limiting factor. At a current of only about 300mA at an input voltage of 12V and and output voltage of 7.2V heat development is not a problem. Continue reading →
