MIMIDI Pedal Board Power Supply - 8 Isolated Guitar Pedal Power Supply DC Output for 9V/12V/15V/18V 100mA 300mA 500mA Effect Pedal (MP-08)

I owned and used this power supply for almost two years and had 0 problems with it. It's been plugged in for nearly the entire time I have owned it. Never caused any electrical problems with my pedals, and I never noticed any additional noise from it. I'm only now changing it out for something with more 9v ports as my pedal board has grown. I will be keeping this as a backup and maybe to use with a smaller board.

Not really isolated outputs in a strict sense. Not to be compared withVoodoo Lab pedal power 2, Fuel Tank or Supa Charger.But this is a step up over your daisy chain power supplies costing $10-$20.For under $30, close to what you will pay for a OneSpot power supply,I think this is a better option. It gives you more power options. It has morepower, about 2A or 2000 milliamps. 9V, 12V & 18V power outputs to choose from.Besides powering all my pedals, I use the 12V for the TC Nova Reverb and the 18V for the OCD.It has two outputs to power up to 500 milliamps for some pedals that need more juice.A little quieter than my onespot and power-all daisy chain power supplies.But basically, I bought this for the power options. I got rid of the 12V and 18V power supply in my board.If I experience less noise, then it's a bonus. If you can't afford a real isolated one, this is the next best thing.

I love this power supply. It powers every pedal on my board. I don't have any hums at all. I saw some higher priced ones on amazon but I can't see why anybody would spend more? This works great and I don't have to keep up with a bag of power supplies! It fits in my pedal case and the wires are more organized.

This power supply is the noisiest I have ever encountered. The notion that it is "isolated" is a blatant lie. I have a guitar amp and a bass amp plugged into the same wall outlet, and used this to power a single distortion pedal for my guitar amp. Turning on the distortion pedal introduced so much ground noise that I could hear it immediately on the BASS amp. (I did not encounter that when using a dedicated 9V adapter on the distortion pedal with the exact same setup.) It's cheap enough so that returning it was not worth it. Well, at least I got an 18V wall wart and a bunch of cables for the power supply I will get to replace this.

Super quiet, reliable, great size. I use it to power my pedal board.

The power supply is OK, and it does have short circuit protection between the outlets. But these are not isolated outputs. I measured continuity between the grounds on the outputs, and it did not read as an open circuit. Compared to my Voodoo Labs ISO 5, the ISO 5 had open circuit readings between the grounds on the outputs, measured at a 200 Ohm scale.If you are not connecting any digital effects, especially anything with MIDI capabilities, you should be OK. The biggest reason for me to use a power supply with true isolated outputs is to prevent leaking any digital noise from one pedal to another over the power supplies on the pedals, especially with particularly noise sensitive pedals, like a wah pedal.This will not supply power to bigger digital effects like Eventide, Strymon, or Line 6.This is the same pedal as several vendors are selling- identical circuit boards. The Neewer is the best price out of all of them. And even the most expensive of the lot still beats the price on the "traditional" pedal board power supplies (like Voodoo Labs).Would I depend on this for active gigging? Too soon to tell. It's inexpensive enough to have a spare.... but that doesn't help in the middle of a song if it fails.The power supply arrived as advertised. It's very light, compared to my ISO 5 and my Dunlop Power Brick. Powered on just fine. I'll update tomorrow after hooking up to my amp.

What a killer deal. I also have the Donner DP-2, which I love, but this appears IDENTICAL, and costs a lot less (fifty vs thirty). This is a steal. If you aren't ready to jump into the deep end with a Voodoo/Yankee/whatever, this is the absolute best solution and the best value!I am leaving off one star only because I don't know how it will perform over time. If it keeps up (or doesn't), I will update my review.

Awesome!

Works well, no issues. I use it with: Yamaha Compressor, Boss Dist, Aria Chorus, EH Trem, Boss Delay (and a EH 360)

This works well and is ok build quality. Each output is just passively isolated (capacitors, inductors and resistors) and the capacitors are just moderate values and quality, so the power filtering is better than nothing, but not super stellar. Depending on the power supply for it and your current draw, it can still be quite noisy & leaves audible noise in your signal chain. If you use a very low noise 18v supply to power it, that would likely help.Definitely not the caliber of a Voodoo Labs or similar, but it's nice and light and works decently especially just as a power hub.If one were inclined to upgrade the electrolytic capacitors in it and give it a nice clean 18v linear supply, that'd help. But at that much effort, better off to just buy something high quality.

Good works great

I am writing this review in October of 2018. I bought this power supply in March of 2017 for use in my "alternate" pedal board. A back-up board if you will. Something light and grab-n-go for taking to small jams and such. As such it did not see much use compared to my main rig. At first it functioned as intended, being used for maybe a couple of hours a month. After about a year or so I began to notice some of my pedals were getting noisy. It wasn't the OD/Dist pedals that were noisy. It was the filters and modulation units that were acting up. They would work fine on a battery or with another power supply but not on the board plugged into this supply unit. I thought maybe I was taxing it too hard because I was using 7 of the outputs and one of them was one of the higher power ones for a Strymon box. I removed some of the pedals from the board including the Strymon and it worked as expected again for a few months and then one day it just quit. I pulled the board apart and tested continuity on all of the supply cables and they were all fine. Then I check the output of the unit and there was nothing. Then I checked the output of the wall wart converter that powers the box. It is supposed to put out 18 volts but my perfectly functioning FLUKE tester measured an average 0.050 volts and it was fluctuating pretty wildly, ranging from 0.090 to 0.001 volts. Naturally I could buy a replacement adapter but that kind of defeats the economy of buying this inexpensive supply. I would recommend spending more and getting something better. I have since replaced this unit with a the 1-Spot I took out of my main board that has been running hard for 3 years. It's 3 times the price but it works. My main board now sports a Zuma.

this power supply works perfectly and the two 300mA output help a lot to power my Trio Band pedal. I recommend.
