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. Review: Dependable - 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. ## Features - 10 ISOLATED OUTPUTS:Donner DP-1 9V Guitar Pedal Power Supply has 10 outputs ,which includes 7 ways 9V 100mA, 1 way 9V 500mA, 1 way 12V 100mA, 1 way 18V 100mA - NOISE REDUCTION CIRCUIT DESIGN：Donner Guitar Pedal Power Supply Quality is made of aluminum alloy material, which makes it light, and portable.

However, it does not mean absolute isolation in the circuit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WHLLDWO | | Amperage | 500 Milliamps | | Best Sellers Rank | #503 in Musical Instruments ( See Top 100 in Musical Instruments ) #127 in Guitar & Bass Accessories | | Brand | Donner | | Color | Black | | Connector Type | Barrel Connector | | Connector Type Used on Cable | Barrel Connector | | Customer Reviews | 4.5 out of 5 stars 7,859 Reviews | | Enclosure Material | Aluminum | | Form Factor | Compact rectangular box | | Input Voltage | 240 Volts | | Item Dimensions | 6 x 2 x 72 inches | | Item Weight | 6.9 Ounces | | Manufacturer | Donner | | Material | Aluminum | | Maximum Power | 9 Watts | | Mfr Part Number | DP-1 | | Model Number | AS2401A | | Output Current | 5 Amps | | Output Wattage | 9 Watts | | UPC | 708302975773 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Donner - **Color:** Black - **Connector Type:** Barrel Connector - **Item Weight:** 6.9 Ounces - **Material:** Aluminum ## Images ![Donner DP-1 Guitar Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 1](https://m.media-amazon.com/images/I/71zv85gC7JL.jpg) ## Questions & Answers **Q: Is this actually isolated? Ive seen others in this price range that appear to be isolated but the reviews have said they arent.** A: The outputs are isolated. Looking at the photos posted by one reviewer, there is a separate voltage regulator for each output. While all the regulators get their power from the same 18 volt power pack, there is no way noise (or a short circuit) from one stomp box can feed backwards through its regulator and cause problems with the 18 volt supply or any of the other outputs. OK, maybe a lightning strike or some other catastrophic power surge in a stomp box might do it, but something that powerful could also travel through the signal cables. In other words, even though there is only one 18 volt power source, all the outputs are isolated from each other by their voltage regulator circuits. Even if they all had their own 18 volt power sources, those would all be plugged into the same 115 volt outlet, so still not 100% isolated. **Q: Before I purchase,...some of my pedals are reverse polarity. "center pin negative" and others are "center pin positive" Will this power supply work?** A: Mine came with two short (about three inch) cables for this purpose. They have female connections on one end and male connections on the other end, so you would simply plug the cable coming from the power supply (the one that you want to reverse polarity on) into the female end of this cable, then plug the male end into your effects pedal. If you have a meter handy, I would check the output of this cable before I plugged it into the pedal, just to be sure the polarity has been reversed properly. (better safe than sorry) **Q: Can someone enlighten me what is the 9v 500ma is for? can i use it on regular 9v boss pedal like boss cs-3?** A: Just bought this and it looks like it won’t turn on with my RC-500 off of the 500 port. You can plug it in once the other pedals are powered up, but it won’t power them all up together which is hella annoying. **Q: I lost the power adapter for mine (I think someone took it) how do I replace without buying an entirely new rig?** A: Just buy new power adapter home skillet .Just make sure the output is 18 V ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great power supply *by J***C on February 26, 2026* Works great so far.
