Portable Waterproof Car Phone Mounts That Stay Put
For most riders and drivers, the RAM Mounts X-Grip is the top pick. It holds phones securely with its rubber spider grip and is built to handle rough terrain. Its main limitation is that it lacks a built-in charging feature.
When you need your phone for navigation or music on a motorcycle, boat, or ATV, a regular mount can fail. Rain, vibration, and wind can knock it loose or ruin it. A portable waterproof car phone mount solves that by sealing out moisture and gripping your device firmly.
This roundup covers seven top-rated mounts that are truly portable. They attach to handlebars, dashboards, or windshields and come with waterproof cases or bags. We compared features like IPX ratings, locking mechanisms, and compatibility with thick cases.

How to choose
Common questions
Can I use a regular phone case with a waterproof mount?
Most waterproof mounts require you to remove your phone from its case to fit inside the waterproof bag or case. A few mounts like Quad Lock use their own cases. Check the product specifications for internal dimensions.
How do I operate my phone while it is inside a waterproof bag?
The bags are made of clear plastic or TPU that allows touchscreen use. However, response may be less accurate. Some bags have a special membrane that improves sensitivity. For phone calls, you may need to use a Bluetooth headset.
Will these mounts fit on all handlebars?
Most come with adjustable clamps that fit standard handlebar diameters (22mm to 32mm). For larger or oddly shaped bars, you may need additional adapters. Always measure your handlebar before purchasing.
How do I know if the mount is truly waterproof?
Look for an IPX rating on the product. IPX6 or higher is considered waterproof for rain. IPX7 indicates it can survive submersion up to one meter. User reviews can also provide real-world feedback.
Can I use a charging cable while the phone is in the mount?
Some waterproof bags have a small opening for a cable, but this compromises the seal. It is better to charge your phone before you go or use a wireless charger if the mount has a charging feature.
Are these mounts easy to install and remove?
Most are designed for quick installation with hand-tightened knobs or clamps. You can install them in a few minutes without tools. Removing them when you park is also simple, which deters theft.
What is the maximum phone size these mounts can hold?
It varies. Many mounts accommodate phones up to 6.8 inches, but some are smaller. Check the product dimensions. For large phones with thick cases, measure the actual width of your phone.
How do I clean and maintain my waterproof mount?
Rinse with fresh water after exposure to salt or dirt. Dry the mount and case thoroughly. Inspect the rubber seals for cracks. Lubricate moving parts with silicone spray occasionally. Store in a cool, dry place.
The verdict
For the best combination of security, durability, and portability, choose the RAM Mounts X-Grip with Waterproof Bag. It is the most reliable choice for riders who face rough conditions. If you prefer a sleek, integrated system, the Quad Lock is excellent, provided you are okay with buying a dedicated case. For a budget option, the MOKO mount delivers adequate protection at a low cost. Whichever you pick, ensure it matches your vehicle’s mounting points and your phone size.
