💡 Compact and Efficient: MFJ-4115 Switching Power Supply, 13.8V 15A Review

Small, light weight, outputs 13.7 volts as shown by the radio on the display. Fan noise is noticeable, but not a problem. Half the size and weight of a full wave device.

Great, simple and reliable power supply. I replaced the fan with a quieter one mentioned by another reviewer. A very nice upgrade, but the best way is to cut off the factory fan connector and use the internally greased jack sockets that came with the fan. The small connector included in the pigtail adapter kit does not fit the board properly.

I was skeptical about switching power supplies, I've always used heavy ones. I didn't need big chances. I needed something small and simple but powerful enough for a radio. This small power supply can be used with any 1 25-50W ham radio on SSB or FM, FT-891 HF 50W radio receiver. 40 m clear as a bell on TX. No HF carriers. Blame. Good for all 13.8V radios. Great for boxing or travel. seller well packaged. buy a second one if you need it.

This has been confirmed by others. I have a new ham radio, I have a radio that was specifically in this power supply. This power supply did not perform as advertised. It failed immediately at high power, it only ran at low power when it should have been running at high power. We've been working to see if there are other issues causing this besides the PSU issue and couldn't find any. I didn't like this article, maybe I just got a bad one. What a pity :(
