Reliable and Works Exactly as Described
Longhorns709—November 9, 2025✓ Verified purchase
This voltage converter works perfectly in my truck setup. It provides a stable 5V output and handles my devices without any overheating or noise. The waterproof design gives extra peace of mind for outdoor or vehicle use. Installation was simple and the wiring felt solid and secure. It has been running consistently with no issues at all.

Good for some dash cams
K.M. Kunz—September 25, 2022✓ Verified purchase
I have installed several dash cameras in vehicles and wanted to keep the wiring hidden. Main problem is that some cameras use 5v and you cannot just tap into a hot power wire. This thing is nice and compact and easy to hide inside the dash. As another has pointed out, there is no instruction sheet, only the wiring sticker on it. For this type of item, I feel this is sufficient. Read more
