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.

Review: A great value for a hobbyist supply. - I got this to help me work on some single board computer (SBC) projects at home. At the office I have access to professional bench supplies, which are expensive. For $18 this does what I need it to do. The following points are for information in case you are looking at this - not complaints, but things to be aware of. I have access to an accurate (Fluke $$$) handheld multimeter at home, not all do. On my unit the voltage displayed on the readout is around 0.1V higher than the actual output. It's pretty much constant regardless of the output setting. So without a load I can set the voltage on the unit from 2.91 to 24.4 volts (indicated) which is actually 2.82 to 24.29 volts (measured). For $18 I can live with that. One thing that may trip you up is that it appears that the output cable uses 24 AWG wire, resulting in a resistance of around 0.190Ω. While that might not sound like much, at the rated 3 amps that's a voltage drop of 0.57V. I've got SBCs that need a 5V nominal supply, and that run some USB connected peripherals. The 5V SBC can draw up to 2A if it's also recharging its backup LiPo battery, so if I set the supply to 5.00V I'll actually be getting 4.92V, and after going through the output cable I'll lose another 0.38V and be at 4.54V going in to the SBC. This is getting very close to the USB sec minimum of 4.40V, which is what goes to the USB-A ports on the SBC via current limiters that introduce a small drop themselves. This can all be cured by raising the displayed voltage to 5.5V, but it's something to be aware of for those that don't have the ability to measure the actual voltage under load. I love the huge array of cable ends that come with it, including alligator clips and a screw terminal block. One occasionally encounters a device that's been designed for some reason with the central pin negative, so the polarity inverting cord is a great touch. The adapter itself is equipped with a 5.5x2.1 barrel which is about the most common used in this voltage & current range - so no adapter needed! As another reviewer noted about the only thing I miss is a 5.5x2.1 to USB-A female but those are easy enough to make up with hand soldering. Watch out for the 1 in/4 out 5.5x2.1 fan out adapter - the 4 output leads are TINY and I would not be surprised (based on voltage drop measured) if they are 28 AWG or 30 AWG so you'll get some serious voltage drop through there on any heavy draw. Finally, at low voltages the adjustment is pretty sensitive, so I'll probably replace the knob with a larger diameter unit. It's got a 6mm splined shaft and the knob pulls off, so plenty of those available. Not sure I'd use it as a permanent replacement but for the bench it's great. May buy more.
Review: Adjustable DC Voltage At Your Fingertips - This is a terrific adjustable voltage power supply. I was looking for a simple device to power a very basic LED circuit that I made and came across this item. It has been working brilliantly and offers flexibility to use in a number of applications. I have it mounted to a wall in my workshop. It is compact, adjustable and works!
