Amazing transformer for automotive needs

This transformer is a game-changer in my garage. Thanks to my knowledge gained in practice, I was able to find this product that has changed the way I work on automotive projects. The stabilizer keeps the voltage steady and the step-down function is fantastic for working with sensitive electronics. The build quality is solid and it is user-friendly. However, it would be great to have more detailed instructions included.

Pros
  • Perfect for automotive work with sensitive electronics
Cons
  • Lack of detailed instructions included

Terrible RFI - power converter

The device also works as a 12/24V to USB adapter, but the RFI it generates knocks out FM broadcasts and several broadcast TV channels. Do not buy if you want to receive radio signals.

Pros
  • Delivery was very fast
Cons
  • There are some nuances

Works well and is quite efficient.

Bought a few of these to add USB power ports to my pedal. It was bench tested with 9V to 24V before installation and worked very well over the entire input voltage range. The power transfer efficiency is around 85%, which is very reasonable for such a cheap device. I feed mine from a 9V 1A source. The output is about 4.7V and 1.5A at a full 1A from a 9V power supply. About 1.4W is dissipated as heat, which is normal for outdoor cooling. But it feels hot. Any additional draw and fan may be…

Pros
  • Easy to read control panel
Cons
  • Protection
