I've been experimenting a bit with time-lapse photography lately. Still basic stuff. Right now I have to change batteries every so often which is a pain because it's hard not to move the camera when changing the batteries. I've used the ACK-E6 power adapter to run my camera from mains, but this is only possible in some situations.
So I'm looking to somehow attach some higher capacity batteries to my camera. The regular batteries for my camera (LP-E6) deliver 7.2V. The specifications of the ACK-E6 mains adaptor list the output to the camera as 7.6V 3A.
I've read some things about buck/boost regulators (but I'm hardly an electrical engineer) that I can use to regulate the voltage to that desired 7.2V for my camera.
The goal is to attach a 12V car battery, but have other (smaller, lower weight) options if needed.
I was thinking of buying this buck/boost regulator (or one like this): 3A Power Adapter DC 3.8-32V to 1.3-35V Automatic Buck/Boost Voltage Regulator 3A Drive Power Supply #090040 http://www.aliexpress.com/item/5-PCS-LOT-3A-Power-Adapter-DC-3-8-32V-to-1-3-35V-Automatic-Buck/1609180228.html
I guess the numbers add up, and this should work. But I'm not really sure about the possible risks, because I don't want to damage my camera.
I've searched a lot but I can't really seem to find an answer, so that's why I'm asking here.
Is there a possibility that the 12V from the input goes straight to the output? Are there other risks I have to take into account before attempting this?
