    as always arrived on time, the site 2 and a half weeks, is a simple food variable from 3.68v to 12.5v 5A. I am using it to power a dc motor that if put under stress absorbs a run much greater than 5A but as expected the power supply lowers the voltage in order to maintain a max current of 5A. Now I've been using it for more than 3 weeks, and I must say that it's comfortable and does its duty (even if I'm mistreating it a bit having it connected to an engine). I recommend the purchase, if you have to use it on a laptop (as a battery charger) be careful not to move the knob raising the voltage above the threshold indicated by the computer, it could go into protection or even fry the computer. This last comment does not imply that it is a bad product indeed! you just have to be careful how you use it!!

    Adapter works nicely, adjustment is smooth and fairly accurate. Display is very useful. Highly recommended. Cheers!

    ... ήρθε στην ώρα του..και αρκετά γρήγορα, δίχως φθορά!!! ...για τα χρήματα του..καλός μετατροπέας AC/DV από 3,6-12,7V... ...το μόνο μεμπτό σημείο η ακρίβεια ρύθμισης...αν είσαι της λεπτομέρειας..θα απογοητευτεις... ..η ένταση του ρεύματος είναι 5Α ....το χρησιμοποιώ σε έναν μικρό κινητήρα στο αγρόκτημα 12 V.. τα πάει καλά...και σ ένα παλιό ράδιο αυτοκινήτου... ... πόσο θα κρατήσει δεν ξέρω....

    I bought this power supply to power a small submersible pump at 12V DC voltage. Advantageous is the regulation of the voltage and thus the regulation of the speed of the motor. At this power supply it is possible to set voltage 3.7 - 12.5V. It is a pity that only one third of the potentiometer path is used for regulation. I tried to load the power supply with 5A at different voltages up to 12V. Worked well without much heating with a voltage drop of 300 - 400mV. When setting 12.5V, there was no voltage drop, see Figure 3. This product met my expectations and I will use it.

    min is 3.85 V max is 12.5 V accurate But not friendly to use as regulated manually with fluctuating

    not yet tested a full power, but the adjustment of the voltage is quite precise. if you need a basic power supply for basic experiments and you don't need a laboratory unit this power is OK. non ancora provato a piena potenza, ma la regolazione della tensione è abbastanza precisa. se necessita un alimentatore base per semplici esperimenti e non è richiesto un alimentatore da laboratorio questo prodotto è OK

    В целом не плохой адаптер, но 5А - это из области фантастики. При 3А и не продолжительном использовании начинает греться. Так же не удобный регулятор напряжения ( больше подошел бы много оборотный). Начало работы не 3V a 3.6V. Тестирование нагрузкой на фото. Для не требовательных потребителей пойдёт.
