Works fine but gets hot.

I've always liked DROK products and this is no exception. It's well built and just works. The 8-50V input range is AMAZING, I can use it with any power supply I have. The only thing that worries me is the heat. There's a 3A max limit, and I've used it so far with some USB string lights that draw 0.05A (according to my test meter), and in a room that's about 68 degrees Fahrenheit it starts to get hot. I wonder how much it heats up at a higher load?

Pros
