tento menič napätia a prúdu je Ok. funguje správne. nemám s ním žiadne problémy. len je potrebné vymeniť regulátory za otočné a väčšie. som spokojný this voltage and current converter is Ok. works properly. I have no problems with it. it is only necessary to replace the regulators with rotary and larger ones. I am satisfied

Arrived with a heatsink's bent corner, and a trimmer awry soldered. Tightening the clamps, I have fear of breaking them or to strip the screws because are not so robust. So the clamping of the cable is uncertain and, checking as usual, sometimes you can remove it from the clamp with only a modest force. Thre's no indication of which is voltage regulation trimmer (right one, looking from trimmers' side) and current trimmer (left one). Tested at 3,7 Amp it heats up enought to be not possible to touch

The product is of good quality, it is exactly that in the description I hope to last as long as possible. Transportation could be a little faster. I recommend this product!
