What to Compare Before Buying
- Cup holder size: The base is stated as adjustable up to 4″ in diameter after the rubber extender is attached. Check that your cup holder is a suitable match.
- Phone width: This mount is stated for devices 2.2″ to 4″ wide. Compare that with the width of your phone, including any case if relevant.
- Phone thickness: The stated maximum support is 0.8″ thick. If your phone has a thick case or attachment, measure it first.
- Viewing position: The 8″ gooseneck and 360-degree rotation affect where the phone sits and how the screen can be angled.
Compatibility, Size and Fit
This mount is intended for cup holder use in a vehicle and is described as suitable for a range of cup holders in cars, trucks, RVs, SUVs, Tesla, boats and golf carts. The main fit checks are still the cup holder diameter, the phone width and the phone thickness.
Because the holder is adjusted by a knob and uses a rubber extender, it is worth checking the exact dimensions of both your cup holder and your phone before choosing an offer.
Before You Decide
Confirm the cup holder diameter, the phone width and the phone thickness before choosing an offer. Check whether the 8″ gooseneck and 360-degree rotation suit the position you want in the vehicle. If your phone has a bulky case or attachment, compare that against the stated 0.8″ thickness support.
