Learn what the Quad Lock MAG Universal Adaptor is, which devices it works with, and how to install it for a secure magnetic mount.
Quick answer
The MAG Universal Adaptor lets you add Quad Lock MAG compatibility to almost any phone or case using a strong 3M adhesive backing.
When to choose the universal adaptor over a dedicated case
If you already have a favorite case or a phone model without a dedicated Quad Lock case, the universal adaptor is the most flexible option. It bonds directly to the back of your device or existing case, so you don't have to switch cases just to use Quad Lock mounts.
The trade-off is that the adhesive bond is permanent once fully cured. You can remove it with heat and patience, but it is not designed for frequent swapping between devices. If you switch phones often, a dedicated case might be more convenient.
Compatibility notes for wireless charging and MagSafe
The MAG Universal Adaptor works with the Quad Lock MAG system, which uses magnets to align your phone on the mount. If your phone or case already has built-in magnets (like Apple MagSafe), the adaptor can still be used, but it may add thickness and affect magnetic alignment slightly.
Wireless charging through the adaptor is possible on most Qi chargers, but the extra layer may reduce charging speed or require precise positioning. Test your setup before relying on it daily.
Frequently asked questions
- What devices work with the MAG Universal Adaptor?
- It works with most flat-backed smartphones and cases. The 3M adhesive needs a clean, smooth, non-textured surface for a strong bond. Avoid applying it to silicone, rubber, or heavily curved backs.
- How do I install the adaptor correctly?
- Clean the surface with the included alcohol wipe, peel the adhesive liner, and press the adaptor firmly onto the center of the device or case. Apply steady pressure for 30 seconds, then let it cure for 24 hours before mounting your phone. Do not use the mount during the cure period. Wait 24 hours after installation for the adhesive to reach full strength.
- Can I remove the adaptor after installation?
- Yes, but it requires careful heating with a hair dryer or heat gun to soften the adhesive, then gently prying it off. Residue can be cleaned with isopropyl alcohol. The adaptor itself may not be reusable after removal.
- Will the adaptor interfere with NFC or credit cards?
- The magnets inside the adaptor can affect NFC signals and demagnetize credit cards or hotel key cards. Keep cards away from the back of the phone when the adaptor is attached. NFC payments may require you to remove the phone from the mount.
