Broke on first use, started smoking. Dangerous and full damage at first use.

I had problems with mine from the start. I just tried turning on the LED as a first test but couldn't get it to light up. I never have electricity. Then, as shown in some tutorial videos on using a lab power supply, I did a 1A short circuit load test and found that there is some current and a voltage of about 0.1V. Good. So, I thought, and now let's try it with a real consumer. I ran an old portable VFD computer game (Entex Pac Man) on 4x 1.5v battery and tried 6v. Smoke from the PSU, LEDs are…

Pros
  • High quality and safety
Cons
  • The cable is shorter than others

Definitely recommend

I have been using this consumable every day since I received it. I charged Sla batteries, used them to test a suspected faulty truck fan motor, charged lithium ion and phosphate batteries and powered some high power LED lights for testing, and anodized some titanium parts (big and small) for fun. I have to say that I am more than satisfied. The voltage reading is sufficient, although the voltage is shown in 0.01 increments (if you are gentle and patient), to overcome the limitations of the…

Pros
  • High accuracy, wide range
Cons
  • Available in white only

EXCELLENT quality (but cheap) power supply!

I really like this PSU. One of the main reasons I bought it was of course its price but the reason I chose it over other cheap ones was that judging by the reviews I saw on youtube others often had problems with the volts/ amp potentiometers (control knobs). They always seemed like cheap single turns that failed fairly quickly. That's why I liked this one, knowing that the potentiometer for voltage control is multi-turn and therefore definitely better quality. I'm just a true electronics…

Pros
  • Excellent heat dissipation
Cons
  • Can't remember
