Works great, no issues I hoped it has display off feature. Little bit too bright in the evening but works without issues. Will update if something goes wrong & stops working in the future.

Works well and has all the tips, so far that I may need. Very versatile and the voltage display matches my meter, so close enough for most things

I purchased one of these and then bought a second. I didn’t have to use it until I was past the return date, so when it turned out to be DOA I was out the $$.
Not a reliable brand from my experience.

It does what you want and does it very well, but also gives you so much more for the money you pay. There are plenty of advantages over your standard Wall Wort type Power adapter, among which are: You get a digital display that shows the DC voltage output value, which is also what you use to set the desired output voltage level. The potentiometer is very smooth and not too tight, such that it’s easy to achieve the actual voltage value you need. The output voltage is accurate to what is displayed on the display of the power adapter, and also it’s easier to use than many of the standard AC/DC power adapters in that you have a long cord that gives you a nice tight plug to use to plug into the outlet verses several other Power Adapters on the market what contain the transformer within the plug that you plug into the outlet source.
The vast and large selection of adapters that are included with the power adapter also mean that this is a multipurpose Power Adapter that you can use with several different devices requiring many different plugs. This means you only need one adapter rather than one for each device, or you have one adapter that works across several other devices. As long as you specify the correct amperage sufficient to operate all your different DC devices, you only have to make one purchase rather than many different ones.

I recently acquired the ‘SHNITPWR 3V ~ 24V 3A 72W Adjustable Power Supply’, and itโs been an absolute lifesaver. The range of voltages it covers and its adaptability is what really sets it apart. With an adjustable output of 3V to 24V and a 3A current, it caters to a wide array of my electronics, from routers and LED strips to small household appliances.
What impressed me the most is the inclusion of 14 different tips, ensuring compatibility with most of my devices. The versatility is unmatched โ itโs like having a universal charging solution at my fingertips. The 5.5×2.5mm, 4.0×1.7mm, and 3.5×1.35mm tips are particularly useful for a range of gadgets I own.
The build quality is solid, and the adapter feels robust yet compact. I appreciate the safety features built into it, like over-voltage protection and short-circuit prevention, which give me peace of mind when using it with my more sensitive electronics.
Another highlight is its efficiency. Iโve noticed a stable power supply without any fluctuations, regardless of the voltage setting. This reliability is crucial for me, especially when working with delicate electronic projects.
In summary, the SHNITPWR Adjustable Power Supply is a top-notch choice for anyone looking for a versatile, reliable, and efficient power adapter. Its wide range of voltage adjustments and plethora of tips make it a universal solution for almost all your electronic needs.

This is a really nice power supply, and does the trick. It seems like it’s pretty good quality. My only caution is, make sure you don’t accidentally bump it and change the voltage while it’s plugged into some kind of electronics. Other than that, I really like it. Highly recommend it.

Good for the price, control is a little flimsy, touchy to get exact voltage

Works well – I have used it to replace a failed power supply for my TiVo. This will give you any power desired between 3 and 24 volts in .1 volt increments. You change the voltage by adjusting/twisting the knob on the top of the power supply. Note that it is very difficult to dial exactly the voltage you want since there are no steps to the adjustment. Sometimes a very little twist on the knob will give .4 volts or so difference.
Pros: Completely adjustable Great variety of tips Polarity changes by additional cord, not just swapping a tip around!
Cons: A little hard to adjust precise voltage, but for most things (especially at higher voltages), a half a volt (.5) or so won’t make a difference If you are light sensitive, the light that indicates the voltage is bright red LED, and remains on all the time

When I plugged in this adapter, I was surprised to see that it had a digital display with the output voltage.
The voltage adjustment knob is continuous (like a volume control) and moves very easily. This could be a problem if a specific voltage is needed for long term use, as it can easily be bumped by accident.
This device is perfect for a home electronics experimenter for use as a Variable Voltage Power Supply. It even has one tip with clip leads to attach to a home project.

I am posting this review primarily to say that this power supply has a tip that fits the cheap Otvoc Vocbook 16 laptops that a lot of people buy on Amazon. Google searches for the proper connector size are oddly frustrating, and the first “universal” adapter I purchased did not have a connector that fit.
The one search result everyone sees will cost a lot more money and take a lot more time to receive. In the Phoenix area, I was able to order this one at night and get delivery by 8am the next day.
Matched up the tip based on a visual size comparison, set the voltage to 13, and plugged it in. My laptop started charging immediately.

I purchased this power supply for the sole purpose of powering a large tabletop radio and it works just fine as I imagine it would for any other application. The included tips are numerous and great to have around. I can’t get over how sensitive the voltage adjustment knob is though. I’ve never in all my years of knob twisting ever experienced a more sensitive knob of any kind, anywhere. I can literally blow on it and send it up or down .01 volts. Additionally, when left alone for a long period of time, the voltage gradually creeps up or down without anyone touching it at all. As others have said, it can be incredibly difficult to actually tune to your desired voltage because there are no steps in the mechanism.
