Car Cup Holder Expander
Tired of your large water bottle or travel mug not fitting in the car's cup holder? This expander securely holds Yeti, Hydro Flask, Stanley (up to 40 oz) and most oversized cups — no more wobbling or spills on bumpy roads.
Three-Sided Spring Grips
Spring-loaded arms expand and lock around any cup or bottle from 65mm to 100mm in diameter. Fits everything from standard cans to large tumblers.
Stable & Rattle-Free
Non-slip silicone pads inside the grips and at the base absorb vibration and eliminate noise. Your drink stays rock-solid even on rough roads.
Universal Fit – Expands to 100mm
The three-sided spring mechanism expands from 65mm to 100mm (2.56" to 3.94"), fitting most standard car cup holders and accommodating Yeti Rambler, Hydro Flask, Stanley, Owala, Nalgene, and most travel mugs.
Easy Installation – No Tools Required
Simply drop it into your existing cup holder and it's ready to use. The weighted base and non-slip ring keep the expander itself firmly in place while you drive.
Durable ABS Construction
Made from high-quality ABS plastic with reinforced springs for long-lasting performance. Built to withstand daily use, heat, and wear — won't crack or lose tension over time.
Easy to Clean & Maintain
The smooth, waterproof surface makes it easy to wipe clean. Spills and dust wipe right off — no sticky residue or hard-to-reach crevices.
