Meet the Swigzy Car Cup Holder Expander

The Swigzy Car Cup Holder Expander is designed to broaden your beverage options on the go. Available as a standard-length version and a long-base variant, this accessory emphasizes versatility and stability so you can reach for a larger bottle without a spill or a wobble.

Two versions, one goal: a secure, flexible fit

The long-base model adds height and support, helping to keep tall bottles steady even on bumpy roads. The expanding base adjusts from 2.6 to 3.8 inches in diameter, while bottles or flasks with 2.8 to 3.85 inches diameter can sit snugly inside. The result is a universal fit that also accommodates golf carts, UTVs, ATVs, vans, boats, trucks, and RVs.

• Adjustable diameter from 2.6 to 3.8 inches for broad compatibility

Designed for ease and practical use

Patented integration keeps bottles from pulling out, with proprietary retaining tabs that simplify insertion and removal. The offset base minimizes obstruction, so you can use two adapters side by side without blocking adjacent cup holders. Built to withstand rough driving conditions, the expander is crafted from premium materials for lasting performance.
