SoulBay 12V Power Supply Universal AC DC Adapter Charger with Adjustable Output 5V 9V 3V 6V 4.5V 7.5V 12 Volt 1A 1.5A 2A for LED Strip Light CCTV Camera BT Speaker GPS Webcam Router, 5 FT Cord, 30W

Fantastic Charger! I have used this for numerous things while waiting for an oem replacement to fix things around the house. It has every adapter I could ever need and lets you set voltage for any item you need it for. Just a great design and great product.

Excelente funciona como lo esperaba

I needed to replace the power cord on our portable white-noise device; the one we use for travel. Seemed like this was going to be perfect because you can select the output voltage and I was able to match it to the existing device. The problem was that the shoulder on the cord plug was too fat to allow the pin to insert fully in the recess in the device. I used a Dremel tool to shave the plastic shroud and finally it fit. Works as intended now. I can't necessarily fault the 12V power supply because SoulBay did not make my white-noise device. Just know that it could be an issue with some types of equipment.

Perfect

DON'T USE WITH SENSITIVE ELECTRONICS!3V voltage swings of noise and ripple that seems to scale a little depending on which voltage state you select. On the 9V selection... a 3V ripple noise is 1/3 of the output voltage... like come on, ever heard of filtering??For now i'm back to using my B&K benchtop power supply and 9V batteries which going into the same wiring has no noise passing to my electronics. I designed my board for dealing with about -500mV ripple (-0.7V nominal due to the diode) and much more positive ripple since the positive side goes through a secondary 5V voltage regulator for the controls side... That is considerably much more ripple than you generally see on any even half decent power supply. Filtering calculations are not hard guys.I attached a photo of the output as taken by a nice oscilloscope I own. Note that the voltage per division is 5V. the noise you can see covers across most of a single square. The noise can be estimated as about a 3V ripple and is eliminated when connecting the ground of the soulbay to the ground of my benchtop power supply.I had actually been inspired to buy this because a coworker at my Electrical engineering internship had bought a previous version of the soulbay for our work to use and it seemed to be very economic. I liked the newer design having extra attachments but after finding out there was over 3V of AC noise on this new one, I tested the one that was purchased for work and it also has the same issue.Another poster also mentioned radio interference/EMI issues and as it seems this is simply a huge design flaw for this brand of power supply. This amount of noise is exactly why that poster would have seen the interference.

I wish I’d bought this adapter long ago. Adapters get separated from their devices and disappear. I’ve only used this on a Victure trail camera at 6 volts but it worked as expected. The selector switch is tight and has positive clicks. I think it’s a quality adapter and a very good value. It was delivered very quickly.

The banner may be a bit misleading; The main output is 24W with an additional 6W USB port. This can be handy if you need to power two devices. My unit lasted for almost 3 years under constant use of the main output alone.I appreciate the LED indicator that confirms that the adapter is working. (This simple and useful feature is missing from so many other similar power supplies).A nice array of adapters is included. (None of the barrel adapters include a center pin).The connector plug of the main output is 5.5mm OD x 2.1mm ID barrel connector, which might fit a variety of devices without the need for an adapter. However, this plug is about 2mm shorter than the standard (10mm) length of the adapter plugs. This may present a connection issue, particularly if the OEM power supply includes a locking ring. This appears to be a design flaw. Such shortcomings may be resolved with the use of a short (6") extension cable with 5.5mm x 2.1mm male-to-female connectors. Vendors include Amazon, PCH Cables, Valley Enterprises, Show Me Cables, and Parts Express. Look for part number "VB870-DC-MF-6" or "DC-MF-6".Wall plug does NOT fold for travel.Caution:This power supply is NOT compatible with laptops or other high power equipment that would exceed the rated output.It may not be compatible with guitar pedals or other music equipment that require opposite polarity unless a reverse adapter is used, e.g.: SoulBay 5.5 x 2.1mm Jack Reverse Polarity Converter Cable for Guitar Piano Pedals Keyboard, Model: DC01N.How to determine the polarity of the device:You can easily recognize polarity by looking for a symbol near the DC power input of your device. It should have a "+" and "-" at opposite ends, and a "C" shape in the middle. If the dot in the center of the "C" connects to the -, it's negative polarity! (the + is on the outside and the - is on the inside). If it's the reverse of that, it is positive polarity.

The AC adapter for my cable modem (Arris S33v2) was failing. The modem was producing high-pitched coil whine -- probably the capacitors -- and would go into constant reboot cycles. Bought this unit to replace the adapter. Needed 12v 1.5a and so far the new adapter is working fine. Really appreciate all the included barrel inserts.
