Useless Automotive Converter, Waste of Money

This converter failed to regulate the voltage in my car and ended up causing more harm than good. It is definitely not waterproof as advertised, as it was damaged after being exposed to light rain.

Pros
  • None
Cons
  • Failed to regulate voltage, not waterproof

12V solid output is best for power converter

Sometimes also known as a boost/buck converter, the input voltage can be more or less than 12V, the output is stable. Doesn't heat up. I use it for my water pump and solar fridge where the night voltage might be 11.5 and the charge voltage might be 14.5 - so the motors run at the same speed all the time.

Pros
  • electronics
Cons
  • concise manual

Great price, works great

Bought and installed in an RV to limit the voltage on my MaxxAir fan. According to MaxxAir Technical Support, circuit boards in new MaxxAir fans can fail when exposed to actual voltages in excess of 12VDC. Before installation, the voltage in my system was sometimes almost 14V DC. This device has served its purpose and continues to perform excellently. There is also no noticeable increase in the temperature of the radiator.

Pros
  • Current Transformer
Cons
  • So-so
