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.

Great priced power supply
Great bit of equipment for many uses. I like the idea it has come with many different attachments for different types of power sources and even security cameras. The power dial is a bit sensitive to get a perfect voltage but my aim was to get this for a led light project in a large garden area and it worked better than I expected running over 125 meters of led lights at 5.1 v with no flicker or heat buildup. Well pleased overall but would have preferred a step up voltage instead of the dial but you get what you pay for and as this was for an ongoing project Iâm happy!!

Cheap and effective.
Cheap and effective. This is all you need for a surprisingly large number of repair jobs.

Not suitable
Works well but unfortunately not suitable
Prime member –
Works great and with agreat range of adapters
Works very well, though it is not easy to set to an exact voltage. A great number of adapters and the addition of the connecting cables and the polarity reversal cable are an added extra that makes this system that bit more special and even more useful

Just the Job
Presentation was excellent, needed a variable power supply for a several project, this works well, and the range of connectors make the job easier

Needs a range limiter
This is very versatile with a great range of tips from USB plugs (micro- and -C) through various DC jacks and even screw terminals.BUT, as it is it would be very easy to fry your devices!Selecting the output voltage is by a smooth rotating dial – there is no notching on the dial and no scale, so selecting the voltage is a pretty delicate process. I have still been unable to dial in exactly 5V!With a range of 3-24V, on a pretty much linear scale, you obviously only need to turn the dial a very small amount to get to 5V and this resulted in over and under selecting every time.I’ve been working lately with ESP32 and ESP8266 boards which take 5V or 3.3V inputs and the sensit6of this dial means that it would be very easy to stick too much into these boards and fry them.Similarly with USB connections. A smart charger will negotiate the voltage between the charger and the device so as not to fry the device, but with this adapter it would be very easy to stick too many volts into your phone or tablet or whatever and fry that device too.Even inadvertently knocking the voltage knob could push you over what a device can handle, particularly at the low voltage end.For this reason this kind of adapter, when supplied with tips such as USB tips particularly, should have a voltage range selector so that the output voltage can be limited to 3.3, 5, 6, 9, 12V etc.Other than that, output voltage as measured with a multimeter seems to agree with the adapter’s own display within acceptable margins.

Excellent product
Musicman –
There are several adapters that fit different devices. My issue is the first older laptop I have (HP-windows 8.1) the adapter would not fit.The other laptops Iâm playing with (just a factory reset) is working fine (so far)Itâs easy to use. Pay attention to the polarity (reverse polarity adapter included)

This is an excellent adapter very easy to use. So many options. This is a great value, good versatility.

This power supply has been reliable for many pieces of electronics for me to test with. The Voltage tends to drift up slightly when it’s used for a while, but only on the order of .1 to .2V. My unit does not get very hot, is not noisy (no audible sounds). The size is nice: some may not like that this is of the style with a box in the middle of the cable, but this does mean it doesn’t take up a large space on a power strip or outlet to block other available ports.
