Hello I hope this post is appropriate. I have a Browning BTC 5HD Game Camera that runs on 8 triple A batteries. It also has a aux power 12V dc. I found a couple class 2 power supply plug ins at home that I have since forgot what they power. I plugged one into the camera and it lit up but then after a few seconds went dark. Then I tried another and it lit up for 2 seconds. I thought I fried it so I put 8 batteries in and it seems to be ok. Now when I plug it back into either of those transformers it won't light up at all. I am trying to figure out how I can make it run off of one of these transformers because it eats my batteries real fast. I have attached the three options I have and was wondering if anyone could please give me some advice. Also, do I have to be careful when plugging the camera into these could I blow out the camera? Thank you very much.
