Does what it says and pretty well!

An excellent product but had to return it as the fan was too noisy for the target location. Changed down to 20A version, no fan, fine.

I bought this to power a diesel heater which it does without any fuss or bother even during the heavy load periods when the heater is starting up. There is a slight fan noise but nothing intrusive. The only disadvantage would be that it would need to have some sort of protective cover if used in an exposed position outside. Apart from that, it is easy to wire up and there is a small trimmer which can be turned with an electrical screwdriver to adjust the exact voltage that the heater needs - you can see the voltage levels change on the heater display panel as you twiddle the screw and adjust accordingly.

Bought over two years ago to power my workshop diesel heater. It's probably been on for five months of each year for around six hours each day. It's still working well so no complaints.

I finally set this PSU up to run a mobile radio transceiver (Retevis RT95 and others). The initial output voltage was 12V DC as stated. I was able to adjust the output to the required 13.8 volts for the radio equipment using the small trimming pot at the terminals of the PSU. This was very handy. The voltage is quite stable even when I power up other radio units connected to it or draw extra current. The only quibble I have is that the fan runs all the time and does not operate based on the temperature of the unit so even when the PSU is not under significant load the fan runs. It's not particularly noisy but the previous PSU had no fan. The unit is compact and light and seems to be well put together and for the price is an excellent choice for running mobile radio equipment from the mains supply. For safety reasons I would suggest putting this PSU inside a ventilated case or box to prevent accidental contact with the terminals as the mains supply is fed in on one side with the DC output on the other. It could be used as the main unit in a power supply project for a radio shack. EI7CTB

Bought this to power a diesel heater. Has been working a couple of months now with no drama. Seems to deliver a fairly clean DC supply. Seems great at this point.

I bought a diesel heater to heat up my workshop. One of the videos from YouTube showed this 12 V transformer and it really is the perfect solution to use rather than buying a 12 V battery. I would definitely recommend it for any mains to 12v ideas you may have!

not bad had it for 2months 2 connecters broke tho its ok for price
