iOttie Basix Adjustable Dual Cup Holder for Car — Expandable Base, Oversized Main Compartment, Removable Second Holder

The iOttie Basix Adjustable Dual Cup Holder converts a car’s cup holder into a stable, expandable docking station for oversized drinks and a removable second cup or phone holder.

Designed for everyday drivers who need more from their vehicle’s cup holder, the Basix by iOttie delivers a versatile solution that fits most cars, trucks, and SUVs. Its expandable base secures into varying cup-holder sizes while the oversized main compartment accommodates tumblers and travel mugs. A detachable second holder snaps on for a passenger’s drink or can act as a phone stand using the built-in slot, giving you a compact, multitasking organizer without permanent installation.

How does the expandable base adapt to different vehicles?

The Basix features a flexible, expandable base engineered to compress or expand to match the diameter of most standard and oversized circular cup holders. This design reduces wobble and keeps tall or heavy cups steadier through turns and road bumps.

• Twist-and-expand mechanism for tailored fit
• Soft-grip contact points to prevent scratching
• Works in deep and shallow cup holders found in cars, trucks, and SUVs

Can it hold oversized tumblers and travel mugs securely?

Yes— the oversized main compartment is shaped for larger drinkware, allowing many wide-based bottles and insulated tumblers to sit reliably without sliding. The depth and diameter combination provides a low center of gravity for bulky containers.

• Wider opening fits larger bottles and thermal tumblers
• Deep cup well increases stability for tall containers
• Durable construction resists deformation under weight

What is the removable second holder used for?

The snap-on secondary piece doubles as either an extra cup holder for a passenger or a phone holder using its integrated slot. It detaches easily when not needed and secures firmly when snapped into place, adding flexible carrying options without occupying extra space.

• Hooks on and off quickly for two-cup configurations
• Built-in phone slot holds devices upright for hands-free viewing
• Compact storage when removed to save space

How stable is the Basix while driving?

The Basix prioritizes stability with a tight-grip expandable base and rigid upper housing to minimize tipping, rattling, and spills. Its materials and geometry are chosen to resist movement from typical driving forces without adhesive or permanent fixtures.

• Anti-rattle design reduces noise on rough roads
• Firm grip prevents twisting under lateral forces
• Robust plastic body withstands repeated use and loads

Who is this for: The Basix by iOttie is ideal for commuters, rideshare drivers, road-trippers, and anyone who uses larger drinkware or needs a compact phone stand in the vehicle. If you want a non-permanent, adaptable solution to keep beverages and a phone accessible and stable, this dual cup holder upgrades cup-holder functionality without complicated installation.
