Learn how to choose the right adjustable phone holder for your Rivian R1T or R1S. Compare mounting options, ball sizes, and charging setups to find your perfect fit.
Quick answer
For most Rivian R1T and R1S owners, the Adjustable Phone Holder with a 17mm ball and a MagSafe/Qi2 wireless charger is the most versatile choice, but your ideal configuration depends on your phone, case, and charging preferences.
Why the anchor mount matters
The holder uses a patent-pending anchor that expands to lock into place behind the center display, so it doesn't rely on suction cups or vent clips that can fail on bumpy roads. This makes it a secure option for daily driving and off-road adventures.
You can position it on either the driver or passenger side, giving you flexibility based on your reach and visibility preferences. Just note that the anchor version is not available with the rigid arm option.
Ball mount size: what you need to know
The ball mount size affects compatibility with your device mount and how much adjustability you get. The 17mm ball is the most common and works with most phone mounts, while the 20mm and 25mm (1-inch) balls offer a more robust connection for heavier devices or longer arms.
If you're using the rigid arm version, you'll get a 17mm ball on the arm, which is fine for most setups. For maximum stability with a large phone or a wireless charger, consider a larger ball size.
Charging vs. non-charging setups
You can buy the holder with just a ball mount and use your own phone clamp, or bundle it with an active semiconductor cooling MagSafe/Qi2 wireless charger and OBD2 power supply. The cooling charger is great for maintaining charging speed on long trips, but it adds cost and requires OBD2 installation.
If you prefer a wired connection or already have a charging solution, the mount-only version is a budget-friendly choice. Just make sure your phone mount is compatible with the ball size you choose.
Decision rules for choosing your holder
- Choose the anchor mount: If you want a secure, adhesive-free mount that locks behind the center display, go with the non-arm version. It's ideal for both driver and passenger side use. Measure your phone's width to ensure it fits between the display and the dash.
- Pick the right ball size: Use a 17mm ball for most phones and mounts. Choose 20mm or 25mm (1-inch) for heavier devices or if you want a sturdier feel. The rigid arm option comes with a 17mm ball. If you use a large phone or a thick case, a larger ball size provides better stability.
- Decide on charging: If you want wireless charging, choose the bundle with the MagSafe/Qi2 charger and OBD2 power supply. If you already have a charging method, save money with the mount-only option. Check if your phone supports MagSafe or Qi2 before buying the charging bundle.
