I bought this to power on the small old keyboard of my 3-year-old son. It was surprising that this thing works. Even if you're a newbie, you won't get wrong with this. There's an option to choose the desired voltage and use the different plugs for specific instrument or setup. You just need to be careful when you're using it as some connected parts might get broken. I wish the cable was a little bit longer. Anyways, for the price, this is a good deal.
Thanks, Thomann! I would highly recommend this.
Pros
Easy to setup, cheap, and multi purpose charger and plugs.
Cons
Just be careful with the plugs.
