    This is a nice little step down power module with a housing case. It works fine. At the beginning the voltage in the display was not very accurate. But this can be fixed very easy by connecting a multimeter (DC voltage)to the output and doing the following procedure: 1) Remove the input power 2) Press and hold the left button and apply the input power again 3) When the display flashes release the left button again 4) The module has set the output voltage to 5.00 Volt 5) Now you can decrease (left button) and increase (right button) the voltage in 40 mV steps displayed on the multimeter until you get the best value near by 5,00 V 6) At last remove the input power again and the module stores the corrected value.

    Als u handig shopt op Chinese sites kunt u voor vijftien euro alle onderdelen verzamelen voor het samenstellen van een regelbare gestabiliseerde voeding met een uitgangsspanning van 0 V tot 16,5 V en een uitgangsstroom van 2 A, met bovendien digitale metertjes voor spanning en stroom. Is dit een bruikbaar alternatief voor de dure laboratorium voedingen?

    5 minutes to assemble it. Very easy, just plug a Laptop power supply to the source and you will not have any problem to select the desired output voltage. Good feature the amp meter on the display

    This allowed me to use a throwaway power transformer as a controllable universal power source for projects and low power devices. Well made device and plexiglass case protects it and makes nicely mountable.

    This does what it says. I wasn't expecting a puzzle putting the case together, but it was almost fun :o) Be sure to make sure you do a dry run with the case and even then, ensure all the pieces are around the right way before you screw it together.

    Удобный блок питания, особенно в комплекте с корпусом, за такую стоимость. Даже с + доставкой. Думал что не положили две гайки для крепления корпуса винтами, но оказалось что отверстия в нижней части уже являются гайками. Всё работает и мне всё понравилось.

    ★ its a DIY kit, u need to fit all the things in casing. it took less than 5 minute... ★ Since 20volts is mentioned as Best input voltage range i used my old laptop Adapter 20v, 4.5A. Wow the setup is now complete. Calibrate it if needed ★ This tiny device Works perfectly, we can get desired output colt as per our need. i main use 2.8 v, 3.3v, 4.5v, 6v, 9v, 12v, 14.5v ★ i set 14.5v as output and charged my 12v 5Ah battery ★ its peak current is 3A. but using devices upto 2 to 2.5 Amps is a good choice

    The output voltage range 0-16.5V is perfect, measures the voltage (can be calibrated fine) and current, what else do you want for $5? The acrylic case is very creative puzzle like solution :) Mine is a bit different than on previous buyer and BG pictures, additional slot are cut for the display's connector soldering and for two jumper like pads. I think it is for the less tension inside the case. Although I received the item in an uninjured condition, I would highly recommend the seller to put additional foam INSIDE the package close to the display, because other parts can easily damage it during transportation.
