Two out of two dead after few minutes

xdel 01.04.2019

Tried to feed Volta Beats using these PSUs - one seem to be dead from very beginning, the second one worked exactly once and died just after change of a wall socket. The circuitry itself is a bit questionable as you can get discharge on your fingers from input caps if you touched wall plug pins immediately after removal from the socket. Certainly don't worth $12 because it seems that any overcurrent such as Volca produces upon power-on destroys the PSU. I had a hope that multi-voltage pulsed PSU won't be bad but they are pretty bad most of the times without great dependence on the vendor.

not sufficient for Volca

SoundManJohn 06.10.2019

I bought this to power a Volca Modular but it does not work. It does output 9V (tested with a volt meter) but does not seem sufficient for the Volca. The official Korg KA-350 amperage is rated at 1700mA whereas this is only 1500mA. I wonder if that is the issue. Anyway, it does work with other devices like my Digitech JamMan, so it's not a complete loss.

Good but not sturdy

nurk 04.03.2020

This power supply does what it is intended at a low price.
I didn't find any problems in its functioning, but the build quality is quite cheap, with the knob to switch voltage feeling quite fragile and being difficult to tun. The adapters are ok, although they also feel quite cheap.

Bad pedal connection

The Bambix 28.11.2025

I bought it as part of a pedal bundle, so in hope it would fit my pedal right away.
First, it's a universal power supply with several connectors to choose from. To already find the right one was a hassle.
I forgot to change the voltage on first practice but that's on me.
But compared to other power supplies, it never seems to properly connect to the pedal and always seems loose.
This created sound issue on my latest band rehearsal. It took us a while to figure out: "It's this power supply". So, I don't advise it.

Universally fitting for emergency needs

somebobi 12.03.2026

I've bought this power supply a few years ago, so I can confidently post a review about it right now. It's really a must-have for anyone who's experienced a 'sudden death' of one or more DC power supplies on your precious WiFi routers (or internet modems)! This PSU will save you in such emergencies, where you have to replace a failed power supply on your network router (especially after a power outage that ends up frying the original one). You can set your needed voltage using a flat screwdriver and pick your connector tip size at the end, so you can get back to surfing the net, while waiting on your Internet Provider to come with a replacement PSU for you. In short - buy one, so you can be prepared!

Loud high pitched noise and humming.

Varg Wilson 23.05.2018

Yeah... Stay away from this one, makes a crap ton of noise, and on the second day of use i plugged it in, BAM! A small explosion and lots of smoke, of course it stopped working after that. Long story short i do not recommend this product.

Buy it!

Bavarian Barbarian 02.06.2019

Considering how many effects and other electronics come without AC adapters, it's a good idea to have a few of these on hand. I love the fact that the voltage is adjustable and that it comes with multiple plugs so that it can be used with many different products. Sturdy construction and good quality.

Thomann service and delivery was, of course, flawless.

works well without major flaw

Jean-Claude Van Damme 11.03.2022

I've got several of these, and they're all quiet - which is obviously good in a studio. They've all been working well for a couple of years now, without any issue.

A simple power supply

Anonymous 08.12.2016

It creates a slight buzzing sound when it's plugged in which might be bothering if it's close by. The changable tips are great. I bought two of them for powering Volcas. They work fine.

doc_martins 21.05.2018

sturdy and it appears to be long lasting ..
multi purpose for its tweakability
the different connectors should be better labeled for a more intuitive use
for the price .. i tought it would be an isolated power source
