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

This power source works great. It is so much less expensive than power sources at any major music equipment distributor. Donner makes great pedals I've never had an issue.

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.

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!

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.

Works as expected, no noise , good amount of cables, compact, fast shipping, good communication

Great power supply. No extra noise.

The product arrived on time, and works just as advertised. I have no problems or issues (noise, etc.) with the 2 of these units in my large pedal board I built, and it's powering a variety of pedals. I can't really complain about anything, given the price, but having an additional 9V 500mA (or maybe even a 250mA) outlet would be nice for some bigger pedals or FX processors. I've used the 500 mA outlet to power my DigiTech Trio or the JamMan Express, but I have several others that pull more than 100mA. But again, I really can't complain given what I paid for it. I just planned ahead and put AC outlets for some "wall warts" inside my board (very cheap to do).As for design/build quality, I like how compact it is, and the the super-bright blue LED's kind of give my board a slight ambient blue glow from inside that I personally like. They might be a bit bright for some, however, if you have to mount this on top instead underneath or inside an enclosed board. As far as I can tell without taking it apart, it seems solid enough and I have been using it at nearly the maximum rated output with no issues. Concerning longevity, I will have to update this review further down the road, but so far so good!I have already purchased an additional unit for another smaller custom board I'm making for an essentials/bare-bones setup when trying to travel light. I'd buy it again for sure!

A terrificly simple solution for using multiple pedals. Now, set up is a breeze. Everything is connected in seconds and I can leave the wires plugged into the unit until next time.
