The IULONEE Car Cup Holder Adapter is a versatile solution for anyone needing extra space to hold drinks or small items while driving. Made from strong ABS plastic with a newly improved separated base design, it installs more securely and prevents cups from shaking or tipping during the ride.

This cup holder accommodates bottles from 7.5 cm to 14 cm in diameter and can even support oversized containers using the included silicone extension grips. Its adjustable upper arms allow you to expand or retract the opening easily to fit cups, tumblers, cans, and coffee mugs of various sizes.

The expandable base fits a wide range of car cup holders (6.4–10 cm), making it suitable not only for cars but also for motorcycles, trucks, RVs, boats, and more. Thanks to its thickened bottom padding, the holder remains firmly locked in place once installed.

Installation is quick and tool-free: simply insert the adapter into your existing cup holder, twist the top to expand the base, and slide the upper arms to adjust the opening size. Three additional silicone extensions ensure perfect compatibility with large bottles or wide drink containers.

This upgraded cup holder is ideal for long road trips, daily commutes, and family travel—keeping drinks stable and essentials within easy reach.
