Review: One Adapter, Plenty of Options - I had a Windows-based mini computer sitting around the house that I wanted to use, but I couldn’t find the original power cord. I did some research, figured out the voltage it needed, and ordered a replacement from Walmart. Unfortunately, because the mini PC is a pretty obscure model, that adapter didn’t work. I had recently started seeing these adjustable DC adapters with multiple tips, so when I came across this one, I thought it would be perfect for situations like mine. I had never used anything like it before, and out of the box I was impressed with how versatile it was. With 14 different tips and an adjustable voltage range, there are a lot of possibilities for powering different electronics. I immediately tried it with my mini PC. It powered up at 12V, but once I started actually using the computer, it shut down. After checking what the computer required, I gradually adjusted the adapter and found that 13.2V kept it powered and running properly. The LCD display is especially useful because you can see exactly what voltage you have selected before connecting your device. I also like having the on/off position on the adjustment knob instead of having to unplug the adapter every time. Overall, this is a pretty cool and useful tool to have around, especially if you have older or less common electronics and can’t easily find the original power supply. Just make sure you know the correct voltage, amperage, and polarity requirements of your device before experimenting with the settings.
Review: Lots of extras you get with this power supply but even without them it's a great product - 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.

## Questions & Answers

**Q: It stopped working, when a device is plugged the digits start blinking. What is happening?**
A: Probably a fuse on the load side.

**Q: Do you think I can use it , to charge a motorcycle battery and or “ trickle charge “ ( maintain) a car battery?**
A: You would need some electrical experience and battery charger know how and wire in an amp meter to insure volts times amps does not ever exceed the safe rating of this device.  Also need to insure the voltage does not exceed safe voltage to charge a battery at. If you know how, I think it could work for lead-acid batteries but probably not other rechargeable batteries. I recommend instead to use a dedicated battery charger designed for what you are doing.

**Q: Will this accept the adapters with a 5.5mm x 2.1mm dimensions? I ask because the images show the plug to be 5.5mm x 2.5mm and 2.1 seems to be standard**
A: The product description says,
Output DC connector:5.5mm x 2.5mm (inside"+", outside"-")
Reverse polarity converter: 5.5mm x 2.1mm

**Q: Will this work and is it safe for a device with 120vac 60hz 5w input and 16v 100ma dc output?**
A: Hi,
The 3V~24V 3A power supply just power any device which its input voltage is between 3V and 24V, and input current is equal or less than 3A.Thanks.

### ⭐⭐⭐⭐ Great power supply for any device
*by C***K on December 21, 2025*

Been using this for a little over a month for powering a blu ray drive. Works well. The connectors have a firm fit. The power supply can easily be adjusted from 3.3 to 24 volts, but the knob is a little tricky to get dialed in perfectly. It is very sensitive. The case is metal and the cords are thick making this unit very durable. There are no fans so it makes no noise. The only reason for 4 stars is because of the sensitive knob. Maybe have switches to select a power range? Comes with tons of different barrel plugs and adapters making it useful for any device. Even comes with a sheet to identify the size of every barrel plug. Also comes with a plug for reversing polarity.
