Has anyone has any experience with Lukas LK-530?
According to its website it alloys passthrough charging, which would allow charging of battery while running power to the dashcam.
I have an LK-530 that will provide power to the dashcam while in parking mode for 5-8 hrs depending on how much activity is in your parking area. For me it is not enough time so I am looking to buy a Cellink B. Another option is the T Power Plus. Both are shown in the link below:
