CupFone Extension

The CupFone Extension is the perfect accessory for anyone looking for a better position for their mobile phone. The CupFone extension allows you to position your phone in a more comfortable location, and adds greater flexibility to all vehicles. If your cup-holders are too close to your side, then the CupFone Extension better positions your mobile phone up to 4" farther away from you. If your cup-holders too far away and hard to reach, then easily position your mobile phone up to 4" closer. If your cup-holders sit too low, then easily raises the position from an adjustable 1" to 4" higher.

Made from the same heavy-duty USA made ABS plastic as the rest of the CupFone. Offset design allow use of charging cord at all times, and will not interfere with the range of motion. Designed, engineered and manufactured right here in America!
