USB adapter
Since it’s not a cube, it blocks the space in tight power strips. The fold-out prongs are contained in a rectangular container. A smaller box is capable and recommended.

Great Air Monitor
I love the accuracy and sensitivity of the Zen Monitor. The light itself becomes our night light. I just wish the Real-Time Map would show on the pop-up marker the PM2.5, Humidity and Temperature all at the same time.
