Available for immediate purchase. This is a power switch for dashcams that supports parking mode recording. You can set the cut-off voltage and cut-off timer. It is compatible with various brands of dashcams (power connector: miniUSB). The compatibility chart in the photos is outdated and is only a guideline. It worked with a Kenwood DRV-MR450. Brand-name option cables cost around 5,000-6,000 yen, so this is a great deal.
