Stability We take each in-car phone holder out on a bumpy driving test to see how stable it remains and whether the angle or position of the phone changes significantly. Where you put your car phone holder depends very much on the type you’re using. There are three main car attachment types and two phone attachment types to choose between. Here's a comparison of them, which should help with such questions as: are magnetic car phone holders good? Where is the best place to put the phone holder on a car windscreen?

First, you need to choose between the two basic types of car phone mounts: mounts that attach to your air conditioner vent and mounts that attach to your dashboard or windshield.

Top 5 Car Tablet Holders

If you have a standard air conditioner vent (with horizontal slats), plenty of excellent options exist. Vent mounts are often not compatible with circular or small AC vents. Mounts that fix firmly to the headrest of the seat in front of a rear passenger can cost just a few pounds, and are well worth it to stop the cries of boredom and “are we there yet?”. But if they squeak, rattle or fall off in the middle of a trip, you might wish you’d never bothered. Which of the seven we tested will be best at taking the tablets? How we tested them Points were awarded for the ability to shift between landscape and portrait views, and for ease of installing and removing the tablets, because you won’t want to be leaving them in the car when you reach your destination. Finally, we took into account the prices charged at the time of writing. Verdict

Grip We manually shake all the car phone holders to see how well they grip a mobile and whether it detaches.Dash and windshield mounts are more versatile and are typically a better choice for most people. Some attach via a suction base. Others use an automotive-grade adhesive that shouldn't damage your car. You can't easily move adhesive mounts once you place them, though, and the adhesive does break down over time. If you plan to use your mount in multiple cars, or simply don't want to clean gummy residue when you eventually remove it, choose one with a suction mount. And if your car still has a CD player, you can also choose to mount your phone there. Adjustability We test how easy or fiddly it is to adjust the car phone holders to a comfortable position to view your mobile.
