2-in-1 Cup Holder Expander with Phone Holder

This two-piece two-in-one car cup holder expander adapter with phone holder is designed to adapt a vehicle’s cup holder for larger bottles while adding a side phone organizer. The base can be expanded between approximately 2.6 and 3.8 inches by twisting the top of the cup holder, allowing it to fit many cylindrical car cup holders. The rubber tabs are intended to hold 3.2–3.8 inch bottles securely while still allowing them to be inserted and removed with reasonable ease. The detachable phone organizer is added on the side so a phone can be stored within reach, helping avoid searching for it or dropping it into the seat gap. The U-shaped slot is designed to accommodate cups or mugs with handles without requiring tilting, and the deep base is intended to provide balance for water bottles. The product is suitable for large 32/40 oz bottles and compatible phones, but it works best in cylindrical cup holders and may not fit well in most square, oval, or recessed cup holders. Users should compare the vehicle cup holder dimensions with the product before purchase. It is a practical accessory for drivers who want extra bottle capacity and a simple phone storage point without permanent installation.
