Functions great. Electronics are submerged in resin to protect from vibration for great durability. After installation voltage is showing correctly. Amperage was not specifically measured, however, no connected devices have experienced slow charging or low power issues. Screw brackets make for easy installation. Large enough to seat under several existing bolts or can fit most screws. Thin body for easy hiding in existing panel spaces. Connections are tinned copper for effective conductivity. Connection lengths are about 10", allowing for plenty of space for ease of installation. Only drawback is the connections being on same side as charging cable, preventing length of unit from being part of overall length. Charging cable stub is about 12" which allows for decent reach when installing. Utilized with dash cam which makes install as clean as factory. Ultimately great value for the cost.

Came back to buy a few more and figured I’d write a review. I’ve been using the USB-C model for around 2 years. My most recent order was in May 2025. Every single one is still working fine. I have used these to replace other voltage converters they failed or were “failing” like suddenly producing RF interference etc. These have been totally reliable and interference free. I just wish I could buy a bulk supply at a discount as I install a lot of dashcams for friends. Everyone needs a dashcam these days. I prefer these over a hardwire kit from a dashcam OEM because often those have low voltage protection which (especially in Honda’s) triggers too easily, cutting power when starting the car (voltage drop) and it doesn’t recover and power the camera when this happens until you power cycle the car. This is especially a problem in the winter with some vehicles that can drop to <12v. These have never produced that sort of problem, and low battery protection is a huge gimmick. Fist off it would take weeks for a dashcam to drain a typical car battery to prevent starting. But equally relevant is if you hardware the converter to accessory power, it isn’t going to pull power anyway unless the vehicle is on.

Nice and small and easy to connect. I linked it to a AC-DC converter to power a camera hub from a doorbell transformer. It works very well for that. I'd love to see one that can take AD directly, but I made it work. It's pretty small and easy to mount onto a piece of wood. Looks pretty solid.

The PlusRoc waterproof 12V/24V to 5V converter works flawlessly. I’m using it to power a solar USB DAC for a sun-powered, low-power boombox that controls an Android Auto interface, and it handles it without any issues. Solid, dependable converter for custom low-voltage projects.

Very nice device. I used it to hookup a security system 14v line at the front door to a tablet running smart home software. works great and is very small so fits nicely for a flush install.
