3V~24V-72W

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 it’s 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 – it’s like having a universal charging solution at my fingertips. The 5.5x2.5mm, 4.0x1.7mm, and 3.5x1.35mm 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. I’ve 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.

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.

Exactly what I needed to lower the voltage on a Vevor record cleaner so the motor spins slower. Includes several adapters making this thing pretty much universal. Plug and play.

Amazing so far. Instantly fixed my HDHomeRun Prime issues. I thought my 11 year old Prime was dead, but it was just the power supply. One suggestion for this power supply is to add clicks or some resistance to the voltage adjustment knob when turning it OR maybe add a lock on the knob. Someone (kids?) could easily brush up against the knob and raise the power level accidentally while its connected. That would be bad.

This is a compact variable DC power supply. It has a digital display of the output voltage which is accurate to 2 decimal places. The power supply comes with a variety of adapters to fit many DC input connectors. It also has an adapter for bare wires, which is what I am using. The nob to adjust the voltage is very sensitive, it doesn't take very much movement to change the voltage by a tenth or so, so dialing in the desired voltage requires care. Once set, the power supply seems to be very stable over a 50-degree temperature range. I am using the power supply in an unheated outdoor shed and temperature has gone down to the high teens so far this winter. I am very pleased with the quality of this device considering it's very reasonable price.

This thing CAN be very dangerous. I wouldn't recommend using this as a PERMANENT solution for anything. More like a troubleshooting tool to help you find the proper adapter and voltage needed. Because its got so much power and variation, not to mention an adapter that completely reverses the polarity of the positive and negative ends of the barrel, BE VERY CAREFUL and know what you're doing, using it on, find some guides etc. For that purpose, its a VERY useful tool, but I really wouldn't recommend for just a "laptop/random appliance" replacement like I saw a few people mentioning. It doesn't get hot unless you're cranking a lot through it, BUT if you're pushing the WRONG power to something, that's a recipe for disaster and I feel like that isn't expressed enough in the marketing, hence the 2 star deduction. One because its not mentioned, and the other because of just how serious the situation COULD potentially get because of that.

Me gustó que puede usarse para varias entradas eléctricas. Lo necesitaba por un juguete que llegó sin eliminador de corriente. Gracias

Works great as a replacement for outdoor speakers

منتج ممتاز جدا انصح فيه، تقدر تغير فرق الجهد على احتياجك، انا استخدمه في شحن بطارية ليثيوم و ايضا جهاز قص الفلين، بالنسبة ليا له عدة استخدامات و لا لقيت افضل منه في السوق.

Esta Fuente está funcionando a la perfección. Se las recomiendo mucho.

This is great to precisely dial in whatever voltage you need. For example, some devices want 5.1V, not 5V, but it's rare to see an adapter give 5.1 instead of 5.0. Tested with a multimeter and it's accurate and only 0.2V cable loss (e.g. showing 5.4V on display reads 5.2V with multimeter). Unlike some reviews that complained that the dial is weighted too much on the lower voltages, I found the middle of the dial to be about 14V. I actually would be preferred it to be weighted towards the lower voltages since those are the ones you would use most often and it's tricky to move the sensitive dial to get the exact volts you want. The only issue with this is how easy it would be to rotate the dial, even accidently, and thus fry your devices. I'm only going to use this for bench testing, but if you want to use this to power a specific device, you'll need to tape down the dial very well to keep it from moving. Even with bench testing, it only takes a small nudge to accidently move the dial from, say, 4V to 6V, which might be enough to damage your devices, so I have to be very careful and set the volts first, before attaching my device. But overall, I'm happy with it. Just have to be very careful with it.
