Great for parking mode!
This kit connected to my viofo a119 mini 2 dashcam. It is usefulas it unlocks parking mode, and it is better than plugging it into the usb port or the 12v supply in the car as it is more consistent and allows you to continue use of these ports.

Great kit
Worked really well - need to get a fuse adapter but aside from that all worked well, easy enough to install once you know which fuses are for what. Make sure you research how to select the fuses to use

Must have for parking mode
Good kit with a voltage selector but would be better if some fuse taps where provided for the install. Works great otherwise with my a229 pro

Viofo hardwire kit
Great hardwire kit. Set this at 12.4v and so far haven't had any issues with my car battery.

It works
I purchased this to enable the parking mode on my VIOFO A229 Pro 4K HDR Dash Cam, and it works perfectly. It does exactly what it’s supposed to, so I have no complaints. A reliable and hassle-free addition!

Saves me worrying
Saves me worrying about the camera not running while I'm stationary at the roadside with my ignition off. The camera is always ready to kick in at a moments notice.

Buy cheaper -- they come with the taps too!
Didn't work -- wasted my time in buying the fuse taps as well, when I could have gotten one cheaper that comes with taps. Tested with multimeter and this should have worked. I chose this for the brand, but does that matter when they simply don't work? DO NOT BUY.
