AI Verdict
This is a USA-made cup holder phone mount that secures phones 2.37" to 3.37" wide and up to 0.56" deep, featuring an open charging port and adjustable viewing angles.
The CupFone offers a universal design with interchangeable base cups and a StickySleeve to fit many cup holders, and it accommodates phones 2.37" to 3.37" wide and up to 0.56" deep. However, its effectiveness is highly dependent on the specific vehicle's cup holder design, with some users reporting an insecure fit. The plastic knobs are functional but lack the durability and feel of the optional billet upgrade.
If your phone is at the upper end of the width range or you use a thick case, check for the CupFone XL model, which supports phones up to 4.11 inches wide and 0.67 inches deep.

What Buyers Say
Many users found the CupFone to be a surprisingly effective solution for hands-free phone use, often praising its ability to hold phones securely without wobbling, even on less-than-smooth roads. The adjustable base, with its interchangeable cups and StickySleeve, generally adapts well to various vehicle cup holders, though some specific car models still pose a challenge for a truly snug fit. The open bottom for charging is a frequently mentioned convenience, allowing continuous power during navigation. However, the initial setup can be a bit fiddly, with some people struggling to separate the base cups, and the standard plastic knobs feel less premium than the rest of the unit.
“Honestly, I was skeptical about another cup holder mount, but this thing actually stays put in my F-150, and I can finally see my Waze without my phone sliding all over the place. Took a minute to get the base cups right, but now it's locked in.”
Common Praise
- Holds the phone without wobble, even during driving.
- Easy to use for placing and removing the phone with one hand.
- Fits securely in a variety of cup holder sizes due to interchangeable base cups and StickySleeve.
- Allows full access to the charging port while the phone is mounted.
- Adjustable tilt and rotation provide a clear view for navigation.
Common Complaints
- Separating the adjustable base cups can be challenging and requires the included tool.
- Does not achieve a secure, stable fit in all vehicle cup holders, leading to some movement.
- The plastic adjustment knobs feel less durable compared to the overall construction.
- The mount's height can sometimes interfere with gear shifts or other console controls in smaller vehicles.
Ownership Tips
- After a few weeks, the plastic knobs might show minor wear if adjusted frequently.
- The StickySleeve can collect dust over time, requiring occasional cleaning to maintain its grip.
- In some vehicles, the phone's position might block a nearby air vent, affecting climate control.
- The mount's height can be a bit much for shorter drivers in certain car models, placing the phone higher than preferred.

Buying Guide
When looking for a cup holder phone mount, you need to consider two main things: how well it fits your car's cup holder and how well it holds your phone. Your car's cup holders aren't all the same size, so a mount with adjustable bases is key. Also, phones come in different widths and thicknesses, especially with cases, so check the mount's phone compatibility specs carefully.
Phone Width & Depth Compatibility
This tells you if your specific phone, especially with its case on, will actually fit into the mount's grip. Think of it like buying shoes – you need the right size for your foot, and your phone needs the right size holder.
Base Cup Adjustability
This determines how snugly the mount will sit in your car's cup holder. If it's too loose, your phone will wobble and potentially fall. If it's too tight, it won't fit at all. Multiple interchangeable cups or an expandable base are like having different sized inserts for a perfect fit.
Open Access for Charging
This means the bottom of the mount is open, so you can plug in your charging cable while your phone is mounted. Without it, your phone might die mid-navigation, which is as frustrating as running out of gas on a long trip.
Alternatives
If this mount doesn't fit your needs, look for models with a wider phone grip range for larger devices or those with a more robust, non-plastic adjustment mechanism for increased durability.
