    handy little boards for when you need a higher voltage than the supply, just wish they had current regulation too, fitted with a current limiting resistor after the board is necessary otherwise they get very hot (170'c+) on the IC and Diode or use with banggood step down board with current regulation in this case making a 26V 1A charger from a 12V supply

    Good converters. Work as expected.

    Nice little step up module. 2-24v boost with a max output current of 2A. Always start with low voltage 2-5v and increase the pot. output voltage to +3-5v from where you want to have your steady input voltage at or it will burn up. Other than this little cork this is a great step up module for the price! Good for low current projects.

    Leider sind 5 Schaltungen von 10 Stck. nicht in Ordnung gewesen. Das Poti vor Beginn 20 Drehungen nach rechts drehen, dann zurück bis die gewählte Spannung am Ausgang anliegt, dann ggf. belasten. Messdaten bei Ue=10V, Ie<1,9A (Schaltfrequenz ca. 3MHz bei Ua=16V) RL=24 Ohm 1.) Ua= 16V --- Ia=674mA --- Pa=10,7W ----> i.O. 2.) Ua= 18V --- Ia=752mA --- Pa=13,5W ----> Zerstörung ohne zusätzlichen Mini-Kühlkörper Meine Empfehlung: Ausgangsleistung max. 10Watt

    The output voltage adjustment pot doesn't use the full range of the multi turn trimmer pot. Only a small area of the trimmer changes the voltage and it's rather difficult to set the voltage accurately. Shorting the two pins of the trimmer closest to the output (shown in the picture of the back of the module) allows the voltage adjustment to use the full range of the trimmer.

    I have ordered step down modules form banggood, and never had a problem frankly they worked better than other online retailers actually, alot mroe accurate. Decided to get Step Ups now....Unlike some of the other reviews here, I actually got all mine to work correctly, and none were dead, the POT on all of them were set really low, like to 0 low or below(if thats possible)...figured they would have left it after testing to like 1-3v something low and not circuit damaging. All of mine were about
