Great

Ease of use and compatibility is good. Quality product. Nice adjustment of voltage.

The product is very useful and handy the only thing wrong with it is that if you accidentally set the voltage to high the item you are charging or using will not work anymore

Voltage adjustment was the exact thing needed to replace the power supply for a 19.5v POE switch for my cameras. It was much cheaper and easier than getting a new POE switch as they are not being made anymore by the manufacturer. Just be mindful for you applications the polarity of the tip!

I bought this as a universal charger for a variety of older devices for which the OEM power cubes have died. A couple of cordless drills that use 4V, charged well at 4.2V. Note that the output voltage displayed varies in steps, not continuously. That might be a problem with a voltage sensitive device, so be warned. Also tried it on a LED floor lamp that had a 19V DC cube. I found that I liked a slightly lower light output at 15.6V, works fine at lower than specified voltage, nice! Overall, I'm happy with it. Buying another so that I have one for the floor lamp and another for my original purpose!

This is the second unit that I received with (what I’m assuming is) a defective voltage potentiometer. The voltage adjuster (potentiometer) drifts (literally moves on its own) after the supply is turned on and adjusted back to its lowest setting which causes the output voltage to not remain constant between 3.68 and 8 volts. A related issue is that you can no longer adjust voltage below 8.62 after unit is turned on and set to a voltage higher than 8.0. Yet another problem is that the measured output voltage drops to 0 when setting the control to any voltage higher than 20 even though the display indicates otherwise. The cutoff range is actually 20 - 24 volts. The end result is that this power supply will not reliably deliver voltages lower than 8 and nothing at all between 20 - 24V. This product has potential but I would not recommend it unless the manufacturer improves their quality control.

Great unit. Working well Why did you pick this product vs others?: love

I had no idea it was low power, but still profoundly useful. Easy adapter swap, but very touchy dial! With the digital display it is still very easy to use. Glad I ordered it, even if it didn’t quite fit my need I had in mind.

works well

1- Arrived on time 2- Comes with many different tips to fit many devices 3- Provide Min 3.5 V up to 24.5 V. 4- It gives + voltage rating by 0.5 V than what is on Voltameter and this is common with all other adaptors that I had. 5- Comes with reverse polarity cable.

boa qualidade, porém atendeu parcialmente minhas necessidades.

Great unit Works well Use it daily

Took me a bit to find the right connector plug, but it works. One thing to note is to not be on your laptop while it charges. The volts fluctuate and then doesn't charge properly. It's also very finicky, like breathe on the nob it and the volts fluctuate, it also gets hella hot. So fire warning in advance.
