"...These are rock-solid, they provide a stable voltage source for my VHF station, where I run an 80 watt rig...." Read more

"...n't easily find one to add in a 3 wire supply cord. Well, it was inexpensive. I'll find someplace else to use it." Read more

63 customers mention54 positive9 negative

Customers like the power supply. For example, they say it's a good power supply for lights, has excellent power, and plenty of power available. That said, some say the higher power output eliminates problems with the bed and extruder maintaining consistent power. That being said, the power supplies performs well and goes well under 12 volts.

"Outstanding power supply. For HF or CB, I would suggest a true Mega Watt brand power supply for its advanced filtering capability...." Read more

"...Other than that, it's an excellent little power supply with plenty of power avaiable...." Read more

"...It also goes well under 12 volts, I didn't check how far below 11 it would go...." Read more

"So far a very good power supply at a reasonable cost. I am using them to power RGB smart pixel LED string lights...." Read more

27 customers mention24 positive3 negative

Customers find the installation of the transformer to be easy. They mention that the adjustment works well, provides easy, smooth adjustment, and the terminals are easy to attach wires to. They also say the setup is not difficult and that it handles all with ease.

"...V-out adjustment works well, and provides easy, smooth adjustment...." Read more

65 customers mention26 positive39 negative

Customers are mixed about the noise of the transformer. Some mention that it's surprisingly quiet, while others say that it makes a weird noise.

"...Original Review: The fan makes a loud rattling noise after only 4 months of light use. Very disappointing." Read more

"...It was very quiet but cooled the power supply down quickly...." Read more

"...Even at idle, with minimal power. Noisy fan...." Read more

"...… but the one main thing that I love about this one is “IT IS SUPER QUIET!!!!!”..." Read more

40 customers mention26 positive14 negative

Customers are mixed about the fan. Some mention that it works great and runs cool, while others say that it heats up and causes fluctuating voltage. The fan kicks on even with low load.

"...The power supply never gets hot, only slightly warm under high load then the fan cools it right off. It is definitely a good supply...." Read more

"...The bridge rectifier is a GBU808, it isn't heatsinked which could be a problem for 120V operation...." Read more

"...Not a single problem. It has run cool when powering my 100w Kenwood radio and other devices, and the fan has only come on once or twice..." Read more

"Use it for a lot of stuff together. Output is constant and not overheating a tall." Read more

19 customers mention13 positive6 negative

Customers are mixed about the output of the transformer. Some mention that it's stable and handles the loads well, while others say that the power fluctuations were too much, the voltage was bad, and the radio resets.

"...For anything 2m and up, these power supplies work fine. Voltage has been rock solid. The fan only comes on when necessary...." Read more

"...These are rock-solid, they provide a stable voltage source for my VHF station, where I run an 80 watt rig...." Read more

"...but for powering stereo and individual USB ports, the power fluctuations were too much...." Read more

"Use it for a lot of stuff together. Output is constant and not overheating a tall." Read more

17 customers mention6 positive11 negative

Customers are mixed about the dimensions of the power supply. Some mention it's compact and quiet, with a smaller footprint than most power supplies sold for amateur radio use. However, others say the dimensions are wrong, it doesn't fit in their enclosure, and the capacitor is small.

"...The unit is pretty small. I just hope it lasts. Regardless, it saved me from having to buy yet another charger." Read more

"...They have a smaller footprint than most power supplies sold for amateur radio use...." Read more

"...I bought this because it stated 5 inch in length and now it won't fit in my encloser!" Read more

"...I like to add the capacitor are small and there only one temperature control point. It will not be as stable or last as long as the better one...." Read more

Good, build quality could be better
Good, build quality could be better.I decided to open one up and take pics of its insides.This power supply uses the good old Half Bridge topology with voltage doubler and passive secondary rectification, there isn't even passive PFC in this unit, so be aware those living in the EU in case some day the police burst into your home. xdLine filtering consist of 2 Y caps and one X cap, there's not input varistor..The bridge rectifier is a GBU808, it isn't heatsinked which could be a problem for 120V operation.The primary transistors are a pair of D13009K, the manufacturer is unknown to me.The secondary diodes are a pair of 30100 (That should mean 30A 100V), again the same unknown manufacturer. Hopefully someone knows that.The primary caps are two 250V 680 uF caps.Secondary has three 25V 3300 uF caps.The controller chip is a UTC494.Solder quality decent, there are some cold solder points.The transistors and the diodes are mounted to a metal bar that acts as heatsink, there's an isolation layer between the package and the metal bar, there's thermal compound between the transistor/diodes and the isolation layer, and there's no thermal compound between the isolation layer and the metal bar.The fan is a 14V rated fan, is in series with a KSD9700 (A thermal switch) that's normally open, when the temperature reaches 45°C the switch closes and turnsthe fan on. The fan is powered by an auxiliary winding in the transformer.Now, with the switch closed and no load to the PSU, the fan opearates at 7V, when you load the power supply the duty cycle in the primary increases, which in turn alsoincreases the auxiliary winding voltage, to 13V with 150W load.I would personally short the wires of the thermal switch so that the fan is always running, since when running at low loads is pretty quiet anyway.The efficiency of the PSU is about 60% (Terrible even for a half bridge psu).Edit: Efficiency is actually 79.6% (and just hits 80% a 240V) while the power factor is 0.63 at 120V and 0.54 at 240V.

Reviewed in the United States on September 8, 2023
My RV's 12v system worked fine for lights and keeping my battery charged, but for powering stereo and individual USB ports, the power fluctuations were too much. I could have spent hundreds to replace the current built in 110v to 12v converter, but instead I installed this compact unit inside my cabinet and use it to power those specific 12v electronics and it works great!

I decided to open one up and take pics of its insides.

This power supply uses the good old Half Bridge topology with voltage doubler and passive secondary rectification, there isn't even passive PFC in this unit, so be aware those living in the EU in case some day the police burst into your home. xd

Line filtering consist of 2 Y caps and one X cap, there's not input varistor..

The bridge rectifier is a GBU808, it isn't heatsinked which could be a problem for 120V operation.

The primary transistors are a pair of D13009K, the manufacturer is unknown to me.

The secondary diodes are a pair of 30100 (That should mean 30A 100V), again the same unknown manufacturer. Hopefully someone knows that.

The primary caps are two 250V 680 uF caps.

Secondary has three 25V 3300 uF caps.

The controller chip is a UTC494.

Solder quality decent, there are some cold solder points.

The transistors and the diodes are mounted to a metal bar that acts as heatsink, there's an isolation layer between the package and the metal bar, there's thermal compound between the transistor/diodes and the isolation layer, and there's no thermal compound between the isolation layer and the metal bar.

The fan is a 14V rated fan, is in series with a KSD9700 (A thermal switch) that's normally open, when the temperature reaches 45°C the switch closes and turns
the fan on. The fan is powered by an auxiliary winding in the transformer.

Now, with the switch closed and no load to the PSU, the fan opearates at 7V, when you load the power supply the duty cycle in the primary increases, which in turn also
increases the auxiliary winding voltage, to 13V with 150W load.

I would personally short the wires of the thermal switch so that the fan is always running, since when running at low loads is pretty quiet anyway.

The efficiency of the PSU is about 60% (Terrible even for a half bridge psu).

Edit: Efficiency is actually 79.6% (and just hits 80% a 240V) while the power factor is 0.63 at 120V and 0.54 at 240V.
