Package included

1x 72W Universal Power Supply Adapter; 14x DC Tips; 1x Reverse Polarity Converter Cable, 1x Alligator Clip Test Lead, 1x Male DC Power Pigtail 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.

-DC Power Pigtail Cable are widely used in various DC connections, low-voltage cables, CCTV systems, DVRs, car rear-view monitoring system video, and are ideal for home life and work.

-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.

Input: AC 100~240V, 50/60Hz; Output: DC 3~24V Adjustable, Max 3A 72W; It can apply to most appliances which the input voltage is between 3V to 24V and the rating power is equal to or less than 72 Watt
14pcs DC Tips: 6.5×4.4mm+Pin, 5.5×2.1mm, 5.5×3.0mm+Pin, 5.0×2.5mm, 6.3×3.0mm, 5.5×1.7mm, 4.8×1.7mm, 4.0×1.7mm, 3.5×1.35mm, 3.0×1.1mm, 2.5×0.7mm, Micro-USB, Type-C and DC terminal connector. Easily meet the power requirement of your different devices
Built-in Multiple Safety Protection Systems: Automatic over voltage cut-off, over current cut-off, over temperature cut-off, short circuit cut-off. No noise, no explosion, no fire hazard, safe to use. 6ft long power cable makes it convenient to use
Wide Range of Applications: The 72W all-in-one multipurpose AC/DC adapter fit for many 3~24V small household electronics such as LED strips, 3D printer, smart speaks, wireless routers, DC motor, DVR NVR surveillance system etc. For indoor use only

    Accurate Display and Versatile
    I purchase this to build a Colloidal silver generator. Using the 2-wire alligator clip adapter included was the perfect solution. My research indicated that a DC voltage of 20.0 would be the optimal setting to produce the particle size desired. I found the output accurate when measured with a multimeter. This is exactly what I was looking for!

    OK, but check all items
    It works ok, but check all the items for hidden defects. I got a broken wire in one of the connectors, had to replace the unit. Replacement went through in less than a week. All is good.

    Broke immediately after return window closed
    Worked great for week, hadn’t used it. Tried using it again and it won’t output any voltage now. Complete waste of money

    Great small power supply for the shop where the need for a large power supply is not deeded.
    Perfect for my needs and use. Love the voltage display and the analog adjustable control knob. Tons of adaptors for all kinds of things including cell phones . ⚠️ do not use this as a replacement charger unless you are trained and know what you are doing.⚠️ Lipo batteries like in your cell phone can ⚠️explode and burn violently ⚠️if charged improperly. ⚠️

    Product Works Well but Polarity Reverser Doesn’t
    I tested the polarity reverser with a multimeter to check if it was functioning correctly as one of the other reviews had an issue with it and it was incorrect on the one I received, it is simply an extension. If someone didn’t check this first and tried to use this for a center negative unit, it would potentially blow the unit. Otherwise the unit works as expected, I am not sure about the longevity of this item but it feels solidly built.I knocked down a few stars as this problem needs to be rectified, this could damage people’s electronics if they don’t check before using it.

    Worked as expected
    Worked great. Easy to change for different purposes. Output voltage setting is sensitive and a little difficult to get exact, but “exact” is not usually required by typical household products. In use, it worked as advertised.

    Works great, I use when I am repairing equipment when no power cord comes with it.

    It has multiple adapter pieces that connect to a number of items, it had voltage controller that enables the changing of power delivered to whichever device is being charged.

    This adjustable power supply has been a game changer for my electronics projects! The Wefomey Universal Power Supply offers a wide range of voltages from 3V to 24V, making it extremely versatile. It’s perfect for powering various devices, and the 3A output ensures enough power even for more demanding gadgets.The build quality feels solid, and the adjustable dial works smoothly, allowing for precise voltage selection. It’s also compact and easy to store. Overall, this is an excellent, reliable power supply for the price, and I highly recommend it for anyone needing a flexible power solution.

    The item works well. Disappointed in two directions. First this is a used product as the cable ties were loose in the box without being wrapped on the cords; and secondly the power cord is specified as being six (6) feet— alas it is 30”. So if that matters to you, as it does to me for this installation, beware. Otherwise a nice solid piece of kit.
