DC to DC Voltage Regulator Step Up Converter Power Unit Module 3-35V to 5V-45V 5A

Item was as described. Worked fine. Good value for money.

Wanted to have a 21v dc supply from a 12v dc car. Unit worked straight out of the box, liked the ability to see the input voltage and toggle to the output voltage. Tested with a meter and bench psu and it came out fine. Delivered in an electrostatic bag but no other packaging or protective box. Had it been packed a little more securely and had some instructions / QR code I would have given it 5*

Got this little chap connected up and tried him out - worked perfectly. Easy to adjust and the digital display is a help too, saves connecting up a voltmeter. Very happy, recommend.

The cable grips were faulty and the heat sink fell off. I had to glue the cables in place and refix the heat sink to make it work.

I have used/purchased these before, 5A each I have two in parallel 10A output, very low voltage input 4v5 recommend them

Well, the unit does work as advertised, but the quality is so-so. In my case the radiator was detached in the posting, and the thermal glue was so dry - no way to attach it again if you don't have an appropriate glue.

Excellent product

Wired it up with power cable leads which did not take long, connected it to a 12V battery then adjusted the output to 36V. Yes it did produced 36V when connected to a volt metre. I do like the switch so can check the input and output voltages. I would have liked it to be in some kind of box, or at least cover the top over the heat sink. Would I buy again, yes I would.

fonctionne

Parfait

Fa quello per cui è stato ideato nn sono ancora riuscito a provarlo con assorbimenti elevati comunque quello dipende dalle correnti disponibili alla sorgente

Works great, the only function I would like it to have is to display current.

Ich benutze den Stup Up um meinen Fahrrad Akku mit der Insel Solaranlage zu laden.Das funktioniert tadellos. Die externe Spannung lies sich leicht einstellen und passt mit Voltmeter nach gemessen. Achten muss man nur das der Input nur 5 Amper zulässt.Durch den Step Up wird mein Akku dadurch langsamer geladen, als durch das Netztteil vom Fahhrad. Aber ich habe Zeit. Ich benutze es jetzt eine Woche und bis jetzt bin ich positiv überrascht.
