Nice good converters
Have done a quick test, it certainly appears to work as it should, had one running at 12v 0.74A input & 16.2v 0.5A output for a while and it only got a little warm. Turn pot CCW to increase voltage, CW to decrease.
Okay. Okay.
Not yet tested
module boost de tension
Still have to use them but packaging was done very good
they do their job and can't argue with the price
the product is in accordance with site specifications
Handy when you need one.
Arrived exceptionally well packed. It's like on the product photo. For riple sensitive circuits as ripple increases with the load it's better to set higher voltage and use stabilizer. To avoid the risk accidentally using high voltage I may consider replacing the potentiometer with resistor divider later.
