3Pack Weatherproof Outdoor Power Adapter for All-New Blink Outdoor & Blink XT / XT2, with 30ft/9m Long and Thin Charging Cable (NOT for Blink Mini) - Black

This worked perfectly for a blink camera over our garage that was only getting a few weeks of battery life no matter what we did with the sensitivity or blocking out the street and all that. The length is just about perfect - with a little extra - to go from a blink camera mounted outside a garage to the outlet you have for your garage door opener (if you have one) on the ceiling of your garage. It comes with the little nail on clips to hold everything in place too which was nice. The seal at the back of the camera seems to work well. So far so good through summer heat and some borderline hurricane conditions. Ill update if anything changes come winter. Youre going to need a 3/4 paddle bit if you need to go through a wall to get to your power source and some silicone to seal up around the cord. You also need to remove the batteries from the camera before you hook everything up fyi.

These worked for my needs
