CupFone Cup Holder Phone Mount - Stable Hands-Free Car Mount

In this review we look at the WeatherTech CupFone, a cup holder phone mount built for drivers who need a stable, hands-free solution for large smartphones. The bottom line: the CupFone is best for owners of cars, trucks, boats or RVs with standard 3 to 4 in cup holders who want a robust, American-made mount that keeps devices accessible and chargeable while driving. Its strongest selling point is the interchangeable base and firm construction that aims to stop phones from shifting on bumpy roads.

Key Features

• Wide compatibility: Holds many large phones including recent iPhone and Android flagships and accommodates widths from 2.37 in to 3.37 in for a secure fit.
• Interchangeable base cup: The separable base cups let you match the mount to most cup holders that range from 3 to 4 in in diameter for a snug installation.
• Easy installation: Comes with a simple tool to separate and tune the base cups, then rotate the unit to the perfect viewing angle without special skills.
• Charge while mounted: Open-access design allows a charging cable to be plugged in while the phone remains in the holder for navigation and hands-free use.
• Stability features: Rugged construction plus a rubber StickySleeve on the base help reduce movement on rough roads for steadier phone placement.
• Made in the USA: Designed and manufactured domestically and backed by a Lifetime Limited Warranty for long-term ownership confidence.

Who It's For

The WeatherTech CupFone suits drivers who regularly use large smartphones for navigation or calls and need a dependable mount that fits into existing cup holders. It is particularly good for owners of cars, trucks, SUVs, boats and RVs with standard cup holder sizes who prefer an American-made accessory and the option of upgrading subcomponents for style.

Those with unusually small or oversized cup holders, or people seeking a dash-clip or suction solution, should look elsewhere since the CupFone requires a 3 to 4 in cup holder fit and is specifically designed for in-cup mounting rather than dash or glass attachment.
