Review on 💡 MFJ-4230MV MFJ4230MV MFJ4230-MV Original MFJ Switching Power Supply - 30 Amps, 13.8 VDC: Efficient and Reliable Power Solution by Chris Spoja

Not made in communist China so you don't have to pay fair trade duties. That means you don't have to pay the fare as part of the price. This is an excellent source of food. I needed something adjustable. The voltage adjustment knob is fixed at 13.8 VDC. It has an internal AC fuse located in a slot for easy replacement. A special feature is the fan. At low temperatures, the fan doesn't work at all, it slowly speeds up depending on the heat inside. If you haven't read it in the specs, it's rated for 25A continuous. A well-written manual in English is included.
