Russel S. Verified Buyer

Had this supply for a few weeks now. It does a great job. Quiet fan as long as it has a load on it. Running 2 different ham radios on it. Performs great. Only complaint is that I wish the indent notch for the voltage setting was at 13.8 or 14, rather than being at 13.5. Not a major issue, but a simple one. Knowing that a lot of these supplies would likely be used to power radios, I'm not sure why it wasn't. Either way it still performs well.
