Product Description
Fetures:
-Fully Tested.
-Constructed with precision to meet OE standards.
-High quality components.
Noted:
-The power cord between power brick and DC plug will lead to 0.4V~0.6V voltage drop, so we designed the screen displayed voltage was 3.5V~24.5V. Only in this way can your device really get 3V~24V voltage. This is the reason why we advertise the power supply’s voltage range is 3V~24V, not 3.5V~24.5V.
-The maximum current of this power supply is 5A, no matter what you set the voltage to in the range of 3V-24V.And it can be compatible with devices with current below 5A(Includes 5A) (the required voltage of the device should be in the range of 3V-24V.).
-Be sure to power on the power supply first and set it to the appropriate voltage before connecting it to your device.
Package included:
1 x 120W Universal Power Supply Adapter
14 x DC Tips
1 x Reverse polarity conversion cable
1 x Instruction Manual

**USB-C Tip and Type-C Tip are generally suitable for low-power devices with voltages below 12V.
– The outlet size of the adapter and the reverse polarity cable is: 5.5mm*2.1mm.And the above 14 outlet plugs are included.Check the power input port of your device. Please confirm wether it fits for your device before buy. If you can ‘t confirm, please measure it with a ruler.
– The 17cm short black power cord is a reverse polarity converter, not extension wire. It is used to reverse the original polarity of the power supply output port (the adapter polarity from “+inside,-outside”change to”-inside,+outside” after using the reverse polarity cable). Please confirm the polarity of your devices’ power port before use. If the positive and negative poles are reversed, it may cause short circuit and damage your device.

Usefull and works well
This item works well and seems accurate when tested with multi meter. Great veratility being able to adjust voltage down to the 100th’s. My one complaint is any bumping of the large knob will change voltage and it is easy to bump… not sure what the fix is, but is i could lock the voltage in place or cover the knob this would be a wonderful feature.

Finally, a solution for lost power adapters
All of the replacement power adapters I’ve purchased in the past have not had the ability to see exactly how much current they are putting out. With this one, you have a digital readout and a rheostat that allows you to fine tune the power output.Also comes with a very complete adapter set and a polarity reversal connector for the occasional input that is wired in a reverse configuration.

Good buy
I threw the remote in there for size, it’s nice works great plus all the connectors. It has a smooth turn variable voltage control.
JLawson –
That’s one sensitive control there!
This works actually better than my expectations – but the problem I have with it is that the knob is just too darned sensitive. I got this to use as a 5v power supply, and it does a good job at that.But you even brush against the voltage knob, and it’ll be at 4.5 to 5.6v with almost no movement. This needs to be as close to 5v as possible, so I adjusted it then sealed it with Marine GOOP sealant. That kept the knob from wandering – but I’m thinking I should have had to do that. A bit more resistance in the mechanism would have been nice!Overall, like I said I’m very satisfied with it. The selection of tips fits virtually every electronic device out there (except some of the older USB connectors) so it’ll likely fit your use. And I hated taking a star off for something as minor as the knob, but that’s a significant drawback…Would I buy one again? Yes – if I need a variable power supply again I would. Still have a lot of that GOOP left, after all… 😉

Works great.
Found out by accident that the over temp and overload safeguards word perfectly. It will control my sander down to about 4.5 v. Setting stays where I put it and doesnât wander from it. Well worth with the money and a vast improvement over what it replaced.

Update: Company Replaced Product. Failed with almost no use. Didn’t work well when it did.
Original Review: So I had bought this product hoping to have a quick and easy simple PSU (Power Supply Unit) to do things like testing motors. Charging batteries. Testing LEDs and so forth. And especially using it to check if any of the many old laptops I’ve acquired through the years still funtion. This seemed like a good deal for all of the above. However firstly I was disappointed to find that out of 9 laptops I had to test there was not a single one that this fit right. Some were proprietary ports which I can’t expect it to cover all of those. But 5 of them were basic, run of the mill barrel jacks which it amazes me this wouldn’t cover. 4 out of those 5 laptops had the same dimension jack too across multiple manufacturers and many manufacturer years so it was a common jack size… You definitely shouldn’t get this expecting it to be a ‘Universal Laptop Charger’ as portrayed otherwise you are almost guaranteed to end up with a miss… Now the other problems… Firstly even when this did work the voltage was finicky. Only the first half of the knob on mine actually did anything, when it reached that point and past it was always then locked at 24v. So with half of the knob that’s actually more like a quarter… (Given the knob is only 3/5 turn total and that the click On/Off takes up a good chuck of the half of the usable remaining half of the knob.) You are supposed to adjust accurately between 3v and 24v… It was possible but even a slight bump of the unit could cause the voltage to shoot way up or down. Maybe damaging something in the process that was poor manufacturing from the start. Secondly the voltage during use would wander up or down a half volt to a full volt a lot of times when used. Wouldn’t happen immediately, would happen over a couple hours when I’d have something charging. So say I have a small flashlight set at 5 volts to charge. I could come back in a couple hours and see it at now 4.5v or 5.5v. That wandering shouldn’t happen. Now thirdly and the real meat of it. I wanted to test this across the voltage spectrum and different loads to test thier 5Amp claim but I didn’t even have the chance to do that as even though I used this a couple of times for basically nothing, it is completely broken. The unit now just stays at 24.4/24.5v no matter the knob position. Something has failed spectacularly with the unit for no discernable reason. That is unbelievably dissponting, especially at $30ish dollars that ain’t cheap. Also even when switched off the unit will pulse on and off for several minutes afterwards. Overall the product was a huge disspotment and not even remotely a good value if this is the quality. Hopefully I can save you some trouble with this. Update: The company seen my review and replaced the defective product. And the new one seems to be working fine. The knob for voltage is still quite sensitive. And the voltage does wander a bit and most of my other complaints in the original review are still applicable… But I am glad the company is at least standing behind their product. As such I am increasing the score from 1 star to 3.

Can use my KVM Switch again
Had a KVM switch that is supposed to run on like 5v 2.5 amp and swapped to 3 amp and still having issues at times. It must need somewhere 3-3.5 and 5 ampNow, with extra amp powe, I am able to use memory Card reader in the USB slot of KVM to move files from my gaming PC, to my work PC, or Gameing server and … next test will be seeing it has enough power to use my Corsair k70 LUX RGB keyboard and Scimitar RGB Elite mouse on the KVM.This power supply save and expensive 4 slot KVM switch from going in to the trash
