back to 10-40 to 10-50v 250w 6a HiLetgo boost

boost converter review:


excellent medium-power boost converter


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
