MFJ 45 Amp MightyLite™ power supplies weigh just 5.5 lbs., that's 8 times lighter than an equivalent conventional power supply.

These 45 amp switching power supplies feature a front panel voltage control that lets you vary the output voltage from 9 to 15 V DC and gives you a highly regulated voltage output. Five-way binding posts are provided for heavy duty use and a cigarette lighter socket for mobile accessories.

Large 3 in. dual meters are brightly illuminated to make it easy to monitor load voltage and current. An internal fan cools these power supplies for long life!

Compact and powerful!

MFJ-4245MV
The power supply is much more compact than a traditionally designed power supply would be for this amperage and much lighter, making it a great power supply for taking to remote locations. The fan noise is noticeable but not overly so. Meters are large and easily visible. Recommend it highly

I like having outputs on the back of the power supply (12v, 5amp) for things like watt meters, etc so you do not have a lot of wire attached to only one power distribution point on the front of the supply. The fan is not too noisy, though you can hear it running. The large, well lit meters really set this power supply off from all the others, as does the 45 amp peak wattage with variable voltage.

I would give this supply a five star rating except for the on/off toggle switch. It was loose. Other than that I works like it should. I still like the needle meters over digital. Nice bright LED's light the meters too.
