Another great choice in a portable cup holder, this unit works in a similar way to our top pick with a few minor adjustments and a slightly higher price. With a simple twist of the top half, you can expand the base of your new cup holder to securely fit into any standard car cup holder.
Ranging from 2.5 to 3.75 inches in diameter, check the size of your current option before purchasing this product. The central unit can handle bottles, cups, and mugs up to 3.4 inches in diameter but double check that your travel mug will fit. Anything smaller than this will be securely held in by the addition of the rubber tabs around the head of the cup holder.
