Review on SHNITPWR Universal Adjustable Switching 100V 240V by Davey Kamau

I have used this power supply for a variety of purposes including: starting an aquarium pump, charging 12v lead acid batteries, starting some small circuits and quite a bit more. The dial is fairly accurate, only 0.2 volts from the display at worst (under some types of loads), but it's usually accurate. I've only used it for a total of 100 hours so I can't guarantee how long it will last, but it's worked really well so far. As for all the extra ports, I honestly never needed them and don't need them. I use a lot of them. The only one I used regularly was one that had positive and negative wire leads instead of round terminals. This connector developed internal conduction problems after mishandling, resulting in one of the electrodes not working. The power supply works, but this additional connector no longer works. Considering they look like cheap bait for more, that's not too surprising. Overall I can recommend the adapter given the price. Unlike more expensive lab power supplies, it has very low power consumption, which means it can be used for long periods without worrying about overheating or other issues.
