Car Cup Holder Expander for Large Water Bottles

Swigzy invented the expanding base cup holder adapter, which is unrivaled in quality and performance. We encourage you to compare our adapter in person with any other, and we're confident you'll be satisfied with your decision to purchase the original, patented (US 11772539) product.

Thank you for supporting an American small business! Our cup holder expanders are available in multiple sizes and colors to suit your needs.

The car cup holder expander adjusts from 2.8"-3.6" in diameter, with expanding legs that securely hold the adapter in place while driving. Thick rubber pads keep the expander in position, preventing damage to existing cup holders when removing bottles.

The offsetting base of our adapter eliminates 90% of fitment issues. You don't have to worry about blocking the adjacent cup holder or fitting two expanders side by side, as the offset design also helps with cup holders near a center console lid or dash.

To determine the appropriate size, measure the depth of your car's cup holder. The standard length version is suitable for cup holders 3.4" deep or less, while the long base version is recommended for cup holders deeper than 3.4", but less than 4.75" deep. A simple credit card test can help you identify the right length.

The Swigzy Cup Holder Adapter Lineup includes the standard length (black or gray) and the long base version. These adapters are designed to hold 18-40oz bottles, with the long base version specifically accommodating Yeti 14/46oz Ramblers and Stanley 40oz Tumblers.

What sets the Swigzy cup holder expander apart is the use of premium materials engineered to withstand everyday use and temperature changes. Comparing it to any other expander, you'll agree that the quality and performance are unmatched.

The offsetting base of our adapter offers several benefits. It helps in situations where the adapter would not normally fit, such as when the car's cup holders are near the dash, close to the center console, or have a lid. Additionally, it keeps the adjacent cup holder usable.

The Swigzy cup holder adapter works with most cup holders, although odd-shaped or non-circular ones may prevent the adapter from securing tightly in some cases. To ensure the best fit, use the measurement guide to determine the appropriate length for your car's cup holders.

In terms of bottle size, the adapter is designed to accommodate bottles between 2.8" and 3.85" in diameter, which includes most 18-40oz water bottles. For other bottle sizes, check our other product versions.

Swigzy's patented car cup holder expander is built to last, with premium materials and a design that can handle even the most demanding driving conditions. We stand behind our product 100% and are confident you'll be satisfied with your purchase.
