Frequently Asked Questions

Q: Will these metal sticker plates work with my magnetic car phone holder?

A: Yes! These 30mm metal disc plates are designed to be universally compatible with all standard magnetic car phone holders and magnetic dashboard or vent mounts. As long as your mount uses a magnet to grip the device, these plates will work perfectly.

Q: Will the metal plate interfere with wireless charging?

A: Placing the metal disc between your phone and a wireless charging pad may reduce or block wireless charging. For best results, apply the disc to the outside back of your phone case rather than directly on the phone, or use it only in cases where wireless charging is not needed.

Q: How do I apply the metal sticker plate?

A: Simply peel off the protective backing on the adhesive side and press the metal disc firmly onto the back of your phone, the inside of your phone case, or any flat surface you'd like to make compatible with a magnetic mount. Hold in place for a few seconds for a strong bond.

Q: How many plates do I need?

A: One plate per device is typically sufficient. If you have multiple phones, tablets, or vehicles, consider the 15-pack or 30-pack for great value and to always have spares handy.
