It does what it should do! Remember to check the plug socket type and compatibility with your device.
If you are buying a pedal from Thomann like I did, the compatible adapter model is usually mentioned in the page of the pedal. In my case, I was purchasing a Mooer overdrive pedal and the page on Thomann referred me to this adapter, and I chose this one without any worries.
I am usually very careful with adapters and I always use exactly the one that is recommended by the product. But you can be sure you can never go wrong with Thomann. If you are really in doubt, just send an email and ask them whether this adapter would go well together with the product you have in mind.
The adapter easily matched my Mooer overdrive pedal and I have been using it since without any problems.
The input is 100?240V ~ 50/60Hz 0.2A and the output is +9V --- 0.5A and the efficiency level is V. If this matches the specifications mentioned on your pedal/product's box, then you will be safe.
Only have it in mind that the plug socket is Type C, which is commonly used in the EU, and some parts of South America and Asia. The box does not contain any converters, therefore if you are planning to use it somewhere like in the UK, Canada, USA, etc. then you are gonna need a converter.
