I didn't want to do any wiring, so i splurged and got the battery pack but i also added 2 sets of the camera magnets because i used 1 set on the camera and the order on the battery pack. it works great and its very easy for me to switch from trailer to trailer. Battery lasted only 5hrs when the specs say 6 but maybe i didn't charge it long enough
I hooped this bateery pack to a small camera i put on the back of my motorcycle and it worked for 7 hours strait even though the sales man said it will work for 6 hours. I am very satisfied with the quality of the item and it is clearly water and weather proof just by looking at the casing. Also i was pleasantly surprised to see the easiness of charging it when i need it.
