Power adapter

Hey everyone,

Happy to be asking my second question on this forum. I bought a tplink router adapter on ebay for powering my arduino board. By myself understanding it should be a perfect match given I just have 3 sensors and no heavy motors etc in my project. I am hoping to use this to run my board 24/7 for aquarium stuff.

I will be thankful if someone can confirm me. Image is attached.

Fine, as long at there are NO motors at all.

Thanks for confirming.
