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

Works great so far. Has 7 100mA outputs and 3 extra outputs for more power hungry pedals. It is compatible with all of my pedals and the voltages are all adequate for the pedals that I have. No power loss, sag, or noise issues with this unit as far as I can tell. Outputs are easy to switch in and out and the unit itself is quite versatile. I appreciate the ability switch the lights on an off as well. I understand that it's not true isolated output power supply but it sounds great and has eliminated a lot of issues I was having with a one spot daisy chain. It's extremely affordable too which is nice since most boutique power supplies are coming in at $150 plus. I am really happy with this unit and am going to buy another one.

I was surprised how good this was. I have felt that Donner was the affordable brand in the guitar world. This is a nice piece and even can flip polarity when necessary. You get plenty of cables with it and they are short enough to work for your pedal board.

Little noise but has help up for years of consistent use and a few shows.

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'm here to buy another of these to use with my home setup. I bought one for my gig pedal board back in 2022 and (knock on wood) never had one single issue with it. Still going strong. Solid, dependable and no noise. Works for me. I love the blue lights.

Good value for good performance. I velcro’d mine to the back edge of the effects pedalboard. Neat and sweet.

good brand and quality

I was looking for a cheaper alternative to the stupidly expensive power supplies on the market. This one is works perfectly fine with my 8 pedals which are mounted on a pedaltrain JR. It's incredibly light and slots nicely either underneath the board or on top next to the other pedals. Great buy!

Très compact et fonctionne très bien

Excelente fonte! Me ajudou muito com os ruídos.

4 stars because the plug is a bit loose when plugged in. Otherwise its a good product. it still misses a three plug system and thats why no earthing available.
