The advertised video shows the person using a portable power bank, the ones you can charge your phones and laptops with, etc.

Works like a charm. Very pleased with the purchase. This might be the best thing I've bought all year. It's just what I needed for a desk while sitting on the bed.

It has little nooks for things so pens and such don't go wandering around and fall off.

Perfect for standing up while working at my desk, especially since I don't have a dedicated workspace.

Excelente. Item is just as advertised. Great quality and easy storage. The fan is just for decor because it doesn't blow a CM of airflow at all. I bought this for my teen who does homework and plays computer games on her bed.
