Donner DP-1 Guitar Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal

It was easy to set up, came with all the power cables and patch cables, solidly built and works great. A well built, inexpensive power source for your pedal board! Oh and no buzzing!

I have used this for quite a while, and I am fully satisfied with this device. Powers all my pedals without issues.

It can power your guitar pedals like any power supply can. If you are a cheapskate, then buy this product.

Update: As others have pointed out, this is clearly NOT a truly isolated power supply. As Mark says below, maybe "Individual outputs" would be better. That being said, I've been using it for about 11 months now and I've got to say, I like it a lot! It's never failed on my, is producing noise-free power, and has enough ports to handle pretty much everything on my board that doesn't have some special power need. Plus, the LED lights are so bright that I mounted it on my board so that they basically illuminate most of my pedals. So, your results might differ, but I've been very pleased. I'm keeping it at 4/5 stars because it is not truly isolated, as the company clearly implies, but I still think it is a good deal and well made.Original Post:I thought I'd try this out before dropping $$$ on a nicer power supply. At this price I figured it was cheap enough to risk it. I doubted that it could really have isolated plugs for this price, but I think it actually might! I'm no electronics wiz, but from the insides it does indeed look like the different plugs are separate from one another. I've not tried to test it out by purposely shorting anything, but so far it sounds good. I was previously powering a lot of my board with a Boss tuner with the daisy-chain power. That worked OK, but I did get some interference at times. I haven't been able to test my board out many places yet, but I do think it is quieter than it was. Directions have a load of stupid spelling and grammar errors (typical for cheap import), but I was actually impressed with the build quality. Honestly, when I opened it up I expected a daisy-chain of spliced wires inside. Looks a heck of a lot better than I expected! Overall, I think it is worth a try for folks who may not need a pro-level power supply but want something small and slick.

I just received my unit. It does not work. After some troubleshooting, determined that it is the power cord/adapter. The unit itself does work with a different power supply. However, the flow of current or electricity is not proper for some of the units because some are "ON" but don't work at all and one goes off after a few seconds. There's something very specific about the power distribution and this specific cord. I shouldn't have to research this and spend time/effort finding one when I've already purchased something for that purpose.I've contacted the company for a cord solution. Now we wait...10/15/2024 UPDATEDonner Music (the company), ended up reaching out to me after I had sent them a note and followed the proper channels for product support. I had unfortunately already returned the item as it had been several days with no response. Long story short, they apologized for the delayed response, offered to help (if I still had it) and offered to send me a new unit to try out.The new one showed up a couple of days later. It worked just as expected. I've been able to plug in all the pedals I'm currently using for my rig, making the entire thing more efficient and "clean" which is what I wanted. Thank you DONNER MUSIC for stepping up and making things right.It is a "no brainer" type of product and so far, it works for me as intended. If you have multiple stomp-boxes, pedals, etc., to your instrument rig, I seriously recommend taking a look at one of these units and giving it a try. The LED lights give it a nice touch not just cosmetically (as it does look nice), but it gives some much-needed light when you're in a dark stage, studio room or other situation like that.I hope this helps those of you who are researching it or on the fence about getting one.

Daisy chains suck. I’ve used multiple expensive isolated supplies and this works just as well. If you play less than 1 gig a week just buy it. If you gig more buy it as a back up. Zero noise and does what it’s supposed to. I use it with a power conditioner and never have issues.

Works perfectly.
