2-in-1 Car Cup Holder Expander – Adjustable Base, Dual Holder Design

The Gadviu Car Cup Holder Expander instantly turns a single cup slot into two! Designed with a 360° rotatable upper holder and high-quality ABS material, it securely holds multiple cups or items at once — perfect for busy drivers and long trips. The large adjustable frame fits most popular bottles and mugs, including Yeti, Hydro Flask, Camelbak, Nalgene, and Contigo.

Setup takes seconds — simply insert the base into your car’s existing cup holder, rotate to expand the adapter, and you’re done. The adjustable base locks firmly in place, providing a stable grip that prevents wobbling, tipping, or spilling — even on rough roads. Note: May not be compatible with cup holders that have pointed or unusually shaped openings.

The upper holder expands from 3.9" to 5.9" in diameter — large enough to hold your phone, snacks, food container, or even a small tablet. The lower cup holder is 3.9" wide and fits most travel mugs, large bottles, and thermoses. Perfect for coffee cups, drinks, fast food, and road-trip essentials, this cup holder extender maximizes convenience and space.

The expandable base fits cup slots between 2.6" and 3.35" in diameter, making it compatible with most cars, SUVs, trucks, boats, and golf carts. The reinforced design ensures that your drinks stay upright, even during sharp turns or sudden stops.

Crafted with thickened, reinforced ABS plastic and a smooth matte finish, this car cup holder extender is heat-resistant, scratch-proof, and long-lasting. Backed by Gadviu’s quality assurance — if your dual car cup holder is damaged or defective, we’ll replace or refund it immediately.
