    Easy to use, but requires at least 3.5V input to work. I tried with lower voltage and that didn't light up the red diode on the board at all. When sufficient voltage is added, adjusting is easy and the connectors are very clearly labeled. I could get 12V (and more) easily from a 5V 1A battery For... Read more

    Pro: Dimensioni, facilita di cablaggio. Contro: efficienza, prezzo potrebbe essere migliore (pagato 6 euro). Lo uso con un pannello fotovoltaico (di targa ha 45W a 18,6v) per alimentare un circuito a 20V; funziona bene, iniziando a funzionare a 3,4V dove fornisce solo 100-200 mA per arrivare a in...

    It does a great job of adjusting the input to any desired output voltage. Fine design, so it could be build into any project. Good build quality Not usable on my solar panel (I bought one that you could hook up to your car. But i needed the panel on a not so bright place, and tried this as a Even... Read more

    The selected output voltage (14.4V) is very stable when providing any voltage from 4 to 15V. The pot-meter is easy to adjust. Have not tested it with any loads yet. I could not get it to work on low-current power supply (solar panel). I misread "rated input current" as something I this... Read more

    Step up AND step down. Efficient, no heat loss. Indicator light when working. Screw terminals in and out, good markings +/- Accompanying spacer nuts and bolts makes installing in metal encasement a breeze. Good build quality. None that I have found. I have used this to make an emergency USB With... Read more

    Excuse me, for my english. Good construction. No other parts needed. Fully adjustable output voltage within the specified value. This solar panel can not be used because of low internal resistance to completely overload the solar cell, the solar cell voltage drops to 1-2 volts on which this is no... Read more
