Package included
1x 72W Universal Power Supply Adapter; 14x DC Tips; 1x Reverse Polarity Converter Cable, 1x Alligator Clip Test Lead, 1x 4-way Power Splitter Cable
-Alligator clip test lead is perfect for electrical testing such as electronic experiments, bread boarding, circuit testing, battery test, electric appliance test, digital product power connection test, prototyping, and troubleshooting.
-Female to 4 Male Power Splitter Cable enables you to easily Power up to 4 devices with 1 power adapter. There's no need to use more adapters for your multiple devices. Eliminates the Bulky Wall Mounted Power Supplies. Simplifying the Installation Process.
-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 ( reverse the internal positive pole to negative , and the external negative pole to positive). Please confirm the polarity of your devices’ power port before use. If the positive and negative poles are reversed, it will cause short circuit and damage your device.
Instructions on how to choose a suitable adapter:
1. Check Voltage Please find the spec label of your device and check the working voltage. It should be among 3V~24V DC, not lower than 3V or higher than 24V DC. Otherwise, your device will not work or be damaged.
2. Check Current Check the max current your device will draw. It should be equal to or less than 3A, such as 1A, 1.5A, 2A, 2.5A, 3A. Otherwise, your device won’t work well and the PS will be damaged very soon.
3. Check Plugs Check the power input port of your device. The PS is equipped with 14 pcs frequently-used DC tips. Please confirm wether it fits for your device before buy. If you can 't confirm, please measure it with a ruler.
4. Check Original PS If you have a original power supply for reference, their output voltage, plug size, polarity should be the same . If our PS’s current is equal to or higher than original one’s, then our PS will work with your device.

I was at the end of my rope and stuck because I was missing the power adapter to an older camcorder. This did the trick cause I could just dial it in! Worked perfectly!

I’ve returned mine. It may be okay for your needs but it wasn’t for me; too big for what I needed it for and particularly the connector tips were super wobbly and wouldn’t stay attached to the device it was supposed to power. Went for a brand name product with less wattage and accessories. From the look and feel alone you can already tell the difference.

Got a 12 inch car sub and amp hooked to it in my house!

Maybe my expectations were too high for this supply. I expected a fairly accurate bench type power supply. If you are not concerned with accuracy, I guess this supply is OK. However, if accuracy is important, the actual voltage to the plug is 6-8% lower than what is displayed on the unit at the full 3 amp limit. At 24 volts, the output is over 1 volt low.It is possible the inaccuracy is due to loss in the wire lead, but if so, the wire should be heavier!The main power leads seem heavy enough - there is no noticeable warming. This comes with some useful accessory leads - a splitter, a clip lead adapter, a large variety of alternate sized plugs. Some of the accessory leads are quite thin though, and get noticeably warm when attempting to test at 3 amps.In summary, The supply seems solidly built. The voltage control knob and meter accuracy are pretty good. I didn't feel any measurable warming on the supply unit itself of the main power lead out. This supply is OK if you are not real concerned with accuracy. Up to 2 amps load, the output is only down 3-5% which is not too bad. Since accuracy is important to me, I will only use this supply up to about 2 amps due to the larger voltage dropoff at 3 amps..

I tested 1 and 2 amps at both 5 and 20v with good results. The ripple often is above 100mV, which is not great for a power supply, in general. If it were fifty bucks, I'd ding it a star. At this price, it's reasonable. I did not attempt to stress test 24V 3A, and would recommend, with these budget items, to not run them past half their wattage rating for extended periods.The cord set is an impressive assortment, and could be worth it, alone, if it has a piece that you need. A 5.5x2.1 to USB-A female is the only piece I would add. There are USB-C and micro males, and C-female to A-female adapters are easy to get (and surprisingly useful).

I ordered this Universal Power Supply 3V~24V 3A 72W Adjustable Variable 3V 5V 9V 12V 18V 20V 24V to use specifically for an old shortwave radio that has rotted out battery terminals.I have an old radio that uses a 9v power supply with a negative center terminal. Like most folks, I have tons of power adapters laying around from long lost items, but none had the right combination of voltage and tip size. This adapter comes with a giant assortment of tips as well as a polarity reverser that can be used if you need a center negative connector or left off if you need a positive center connector.The output voltage is controlled by a dial. The dial also as a switch (much like an old fashioned volume control). Once switched on, the output voltage is set a 3 volts. Turning the knob causes the voltage to increase to the maximum 24 volts. I did notice that the control is very touchy, requiring very little movement to cause a significant change in voltage. The radio that I purchased this for works perfectly well with this power supply.I will probably use this power supply for other devices. One nice feature is that in addition to all of the different tips provided, there is also a connection consisting of alligator clips. That makes this a good candidate for powering DIY electronics during the testing phase. Keep in mind that the maximum current rating for this device is 3A.

Works great, tested it against my multimeter before use, the display is .05 off…otherwise works as intended

I am impressed with the versatility of this power supply. You can dial in any voltage from 3 to 24 VDC, and you get a large number of tips plus extras. I haven’t seen those extras included with many power supplies. They consist of a 4-way splitter cable, a polarity converter and a breakout cable with alligator clips. I checked the output voltage at several voltages with a cheap voltmeter, and it matched the readout on the display within 0.1 Volts.This universal power supply is going to be a great addition to my electrical tool kit. The only small negative I can identify with this is that it’s difficult to dial in an exact voltage down to the last one hundredth volt. If you want exactly 12.00 Volts, you might have to be happy with 11.98 or 12.01 because the little knob just isn’t precise enough to dial it in more exactly. But realistically, other power supplies where you click in specific voltages (3, 4.5, 6, 9, etc.) probably aren’t any more precise at their preset voltage settings. And also, realistically, if you’re doing precision work you will probably be using a professional bench power supply rather than one like this.Based on the super-versatility of this, I think it deserves a five-star rating.
