## Customer Reviews

### ⭐⭐⭐⭐⭐ excellent medium power boost converter
*by V***1 on July 15, 2025*

I originally bought one of these to keep a supercap box in my vehicle charged up to 14.5v volts, from the 12v supply of the truck, and it's working well. I configured the voltage to 14.5v and current to 5a, and mounted it inside the lid of the lid using stand-offs since it does get warm in use. The back of the board is a thin aluminum plate, which does a good job of heat dissipation, and the large coil does a good job of handling the rated power. I didn't need to add any additional heat dissipation though, the aluminum backing kept temps safe. (though do use standoffs to keep the board away from things like plastics) I ended up buying a second one as a spare since these are reliable and useful to have around when needing to boost voltage. (though you need at least 10 volts at the source) Adjusting the output voltage is easy, just turn the adjustment screw. Current is a little more tricky, you need to apply a load at the current you want, and then adjust the current limit screw to right before it starts cutting back the voltage.I've bought small boost converters and big ones, but this one fits right in the middle, where you have some voltage and need several (but less than 6) amps

### ⭐ Did not function as desired
*by A***H on May 3, 2025*

Did not produce anywhere near the energy output they were advertised for. Though using it would be easy normally, the lack of natural functionality and being limited to 240 milliamperes was a real problem. When adjusted below 17.50 volts dc, the unit would entirely cut off-voltage dropping to the input. I would not buy again, as though it was cheap, it did not work well. It also got quite hot and smoked.

### ⭐⭐⭐⭐ Good boost PS , smaller than previous
*by B***2 on October 4, 2023*

Good unit, all 10 worked. Can easily output 50W, 35v/1.4A with 14v input.Size is smaller from previous units i purchased (30 units). See pic of this smaller unit. I wasnt expecting this and must modify a bracketFuse has been removed, wires are lighter gauge and moved in slightly from board edge.I would like to see wires moved in farther from board edge..make me think they can short to aluminum substrate. Maybe use a connecter with no wires
