The CupFone Duo XL has all the same features as CupFone Duo, but it’s large enough to hold extra-large mobile phones with thick cases. With two phone holders, both the driver and passenger can navigate, make phone calls and deliver hands-free voice commands while easily charging their phones. CupFone Duo XL was designed using the same interchangeable base cups as CupFone, allowing you to custom fit it into your cup holder. CupFone Duo XL features a storage console between the two CupFone heads, a convenient spot for storing pens, pencils, change and more. Fits mobile devices that measure between 2-7/8" wide to 4-1/8" wide and 5/8" deep. 100% designed, engineered and manufactured right here in America!
