SHNITPWR AC Adapter 120W Universal Power Adapter 4V 5V 6V 9V 12V 15V 18V 19V 20V 24V Adjustable Switching Power Supply 100V~240V AC to DC 4V ~ 24V 5A Converter with 14 Tips & Polarity Converter

This power supply is great for a test bench, tons of connectors and variable output. However the brand name is the funniest part. There is an extra N there.

I collect and restore lots of old vintage laptops. This thing really is a life saver, for that. It's seemingly inevitable that I will get a machine that does not come with the original power supply, and sometimes they can be hard to come by. Between this supply and an additional set of tips, you should be pretty much set. 5A output should be enough for most applications, and the reverse polarity cable is a handy addition.I've used this to great success across multiple different era's and vendors, everything from Compaq to Gateway to Sony. Even made a little DIN-7 cable to use with my Apple IIc, and it works a treat.Highly recommended, saves lots of hassle, and money!

I love mine. I've had it for well over a year now, and I use it for several things. It has several useful connectors including microUSB and C type, durable so far. Keep in mind that a power supply is not a charger. The adjustment knob allows you to tune the voltage finely to within a tenth of the voltage that you want, hundredth on anything under ten volts. 5Amp max means that it can handle heavier duty jobs. Good price. Good choice.

As a retired Engineer I have countless small electronic devices and gizmo's that most of which have a (sick) custom power brick and plug.Powering and charging them all while finding outlets for the equally countless chargers takes up lots of time and space. If only there was a better way.Enter this device (and ones like it).Supplied with a generous amount of different tips (and a polarity changer, +universal bare wire block!), simply select the correct tip, dial in the needed voltage and PRESTO - you can ether use (for low power devices) and/or charge your device!I keep one at home and one in the RV (it replaces countless "wall warts").While NO it won't power and charge your high power consuming device at the same time (after all it is only "up to 120W") it is decently compact device with variable voltage output in a decent package at a decent price point.Highly Recommended.

Needed a power supply for a new telescope and did not want to risk one of those cheaper ones blowing out the circuit board. I have bought many power supplies over the years and this appears to be the best so far. It has some heft to it and my multimeter showed the output voltage matches the supplies readout. That feature alone, viewing your output, is pretty unique. If I end up selling the scope someday I will be keeping this.

It worked great until it didn't. After a week or so of continuous use at 15v, the plastic on the adapter started melting. We only noticed it after the smell of burning plastic led to some slight smoldering on the carpet.It works as advertised, and the voltage displayed is accurate. Unfortunately, this is not worth your money with the risk of burning your house down. This is not a power supply you can just plug in and forget.

great

I rarely write reviews. I am making an exception for this product. I bought a used Brother QL-820NWB Label printer that I knew ahead of time was missing the power adapter. I went on Amazon and ordered T POWER Ac Dc Adapter Charger for Brother QL-810W QL820 QL820NWB. When the printer and adapter were delivered the barrel connector on the adapter did not fit the printer. I was definitely upset because the Amazon ad specifically stated that the adapter would work. I didn't want to take a chance for another mistake from a vendor and decided to go with this universal adapter that has a variable voltage. The Shnitpwr AC/DC Adapter is a godsend. My printer required 24 volts and 3.6 amps. The rating for this adapter is 3v to 24volts and max amps of 5. I am happy to know that I now own a power adapter that can easily be used for many devices that I own no matter their power requirements.

Really great power supply. Not as stable as a bench power supply, but it's a 1/3rd the cost and stable enough for pretty much all consumer electronics. Just don't try to power sensitive industrial or scientific equipment with it, and you'll be fine.Comes with a wide array of barrel jack tips, plus USB-C and micro USB (nice!). There was even a tip for an old and obscure NEC Handheld PC (NEC Mobile Pro 900) I have from the early 2000s. Best tip is the screw terminal tip: if you need a tip that's not included, you can source your own and can connect it to the screw terminal.Really great product, I was using those cruddy wallwart style ones before, but this is much nicer. There are screw hole mounts to secure it to a test bench or your wall. Dialing in your required voltage is a snap, and the 8 segment display is bright and easy to read. Has three significant digits.One oversight is a voltage lock button, so that you can lock it in in case the PSU gets bumped and the voltage knob moves. That could be disaster! I'll keep an eye out for an updated model, maybe they'll include that feature.

AC Adapter is easy to use, just dial desired voltage, choose appropriate device compatible tip, that's it. Well made, quality workmanship.

This is being used to supply power to electric curtain window DC motors, which have an operating range of 12 to 24 volts (increasing voltage makes the curtains open or close faster, as the motor rpm goes up).Contrary to other reviews, I do not find the voltage adjusting knob to be too easy to turn - it seem to have just the right amount of resistance to stay in the intended position. (Perhaps this was a fault of earlier models?)Also as others have said, the indicated voltage display stays on for a few seconds after power is cut, as capacitors bleed off. This is normal and nothing to be concerned about.Installation was fast, as the directions are easy to follow.I gave this product 4 stars, instead of 5, only because it has been in service a short while. Hopefully, it will perform flawlessly for years to come.Cheers!

lost the cable for my monitor and this works perfectly to replace it.

Tried on a USB-C laptop - it fried two of the USB-C ports on the laptop. Tried on other devices - it only works with low powered devices, such as 5V micro USB power bank. Tried on few different laptops, it did not work on any of them. The voltage dial is very sensitive, difficult to get it exactly at the right voltage. Also, when device is plugged in and drawing power, the voltage on dial changes...it's not fully stable like it should be.
