Good 12V step-down converter.

I used this step down converter with an 18 volt Ridgid battery to get 12 volts. I use it on a camping trip to power a propane heater, small air compressor, and fluorescent lights. I work very well.

Pros
  • electronics
Cons
  • old

36 volt golf cart converts to 12 volts and operates HART

I have a TON of equipment on my cart. Air compressor for air suspension, front and rear lights, driving lights, LED lights, main unit driving 2 4x6 vehicles and a 200w auxiliary amplifier driving a 10" subwoofer. I've never pushed this converter to its limits but I've loaded the amps hard and filled the air tank and it handled it well and didn't heat up during the time I worked on it. I'll update later, but so far so good!

Pros
  • power converter
Cons
  • unreliable

Doesn't work on 15V, needs more than 18V to start.

I bought this because I needed the advertised 15-40V input range. I tested the unit on a lab power supply under both no load and light load conditions. During both tests I couldn't get it down to 18.2V and when I got it down to 16.2V it shut down. It doesn't work at all at 15V and needs more than 18V when first turned on. I also tested at 40V and the output was stable. In all cases where it worked, the output voltage on my device was 12.3V. The product name and description states that the input

Pros
  • Power Supply Accessory
Cons
  • Poorly designed
