Review on Garmin 010 12530 03 Parking Cable Black by Ryan Person

I think it works as advertised. You can change the voltage cutoff by opening it up and manually adjusting it with a toggle switch. I left 2 cameras (66w and mini) in my pickup in parking mode for 5 days with no noticeable impact on the battery level. As many have said, it's annoying that they don't include one, but the cameras are some of the most compact and premium DVRs on the market. I'm a bit disappointed that they aren't using USB-C in products like the 66W yet. Let's hope the premium they're charging is invested in the next generation of compact and 4K cameras with improved driver assistance features.
