Adjustable Car Cup Holder Expander for Large Bottles

The Seven Sparta car cup holder features an expandable base designed to fit center console cup holders ranging from 2.5 to 3.75 inches in diameter. This universal solution works across various vehicles including motorcycles, boats, trucks, RVs, and golf carts. The holder accommodates most 32 to 40 ounce wide bottles and cups with diameters between 3.4 and 3.8 inches, making it perfect for oversized thermoses and popular beverage containers. Built with durable, solid plastic construction, it includes rubber tabs that grip cups securely to prevent tipping and spilling while driving. The deep base provides excellent stability and balance for water bottles and drinks with handles. The cup holder is easy to remove from its slot for convenient cleaning and refilling. Please note this holder is not recommended for cup holders deeper than 1.8 inches, those with raised edges or square shapes, or vehicles with cover lids. It may also not fit compact cars where the cup holder sits very close to the center console. For vehicles like the RAV4, Forester, Outback, and Prius, consider our Rubber Base Expander for optimal fit.
