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

I rarely leave reviews, but this Donner power supply is very impressive, especially in terms of noise reduction. As a guitar player of 25+ years, I never really took to guitar pedals and preferred simply the plug and play method. Recently, however, I have felt the need for a looper pedal, as I have seen the amazing results that can be achieved with them, and indeed Donner's own Circle looper pedal is a wonderful piece of kit. I decided to keep adding to my rig, until I was satisfied that I had all of the tones I could ever wish for, and the results at first were........ Disappointing. Very disappointing in fact! I got nothing but noise and feedback, especially using distortion or fuzz (I was using a daisy chain power adaptor direct from the plug, which is what I thought was the done thing). Then I discovered these stand alone power units and purchased one, in the hope that it would solve my noise problem. It did! And it did it superbly well! Plug it in, plug in your pedals and off you go. I now have a pedal board with 8 pedals, limitless tonal possibilities and find myself playing a LOT more than I was. Most of my pedals are so called 'budget' pedals, but to me, there's nothing budget about the way they sound, which is ultimately what I consider the most important thing. Sits right underneath my Donner pedal board too and the cool blue LED is a very nice touch. Highly recommended! 😊

As a beginner in the world of pedals, I've always found having to have an extension lead for several pedals incredibly inconvenient. I've tried a multitude of different electric plugs with different ends and they've all been very unreliable and thus unsuitable for a live scenario. So after much frustration I went to search for a power supply. In my mind, they'd always been prohibitly expensive putting it out of the price range of an amateur musician. When I found this for such a low price, I was initially quite hesitant but after playing with it for the past few weeks, its played perfectly with no issues whatsoever. There's nearly no unwanted noise coming from the power supply, even when running through some pedals running on battery power and some plugged in, all of different makes. With ten outputs, I can put all of my pedals on at once with no issue. It's small size let's it fit into any pedal board with ease. You can even charge your phone from it (perfect if you use an app on your phone for tuning)! Overall, I cannot recommend this power supply enough, don't let the low price put you off getting it, it's well worth every penny!

Excellent power unit for the guitar effects pedals that I have ! Good quality and excellent value !! Thumbs up from me 👍👍🎸🎶thanks

Light as a feather, although it does a decent job of powering my pedals with minimal noise which is perfect for when I record my guitar into my DAW. The lights are a bit too bright for me, so maybe blue wasn't the best LED choice - thank goodness you can turn them off. All in all, it's decent for the money. HOWEVER, there is one HUGE caveat, which Donner needs to change ASAP, is the false advertising. The packaging as well as the listing state that the supply is isolated which is not true, and has been debunked many times (a simple continuity test shows that each supply has a shared ground), so that's one thing that should be taken into account when purchasing. If Donner could be truthful and admit the supply is not isolated, but filtered (which for me is ok for now), and can come up with a revised one which is actually fully isolated, then I'd buy and keep it. This one on the other hand is a good starting point, but I'd recommend shopping around (you can get an actually isolated supply for £60 here on Amazon). I will be returning this product.

Functionality is great. Immediately stopped the unwanted noise on my buzzier, cheaper, pedals. My only negative is the the length of leads provided. Everything has to be cramped together, so you either need longer leads, or another power supply for any stand alone pedals you want sat away from the main board for any reason. In fairness, I intend to purchase some longer leads AND another power supply...
