Frequently Asked Questions

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

A: Yes! These 30mm iron metal discs are designed to be universally compatible with all magnetic car phone holders and magnetic phone stand mounts. As long as your mount uses a magnet to hold your device, these plates will provide a strong, secure connection.

Q: Will sticking the metal plate to my phone affect wireless charging?

A: If placed on the back of the phone directly over the wireless charging coil, a metal plate may interfere with wireless charging. To avoid this, position the disc slightly off-center, or place it on the inside or outside of your phone case rather than directly on the phone body.

Q: Can I reuse these metal plates or move them between devices?

A: The adhesive is designed for a clean, residue-free application. While they adhere firmly, repeated removal and reattachment may reduce the adhesive strength. We recommend ordering a multi-pack so you always have a fresh disc available for a new device or case.

Q: What's the best pack size to order?

A: If you only need one for a single device, the 1 or 2-pack is ideal. Households with multiple phones, tablets, or GPS units — or anyone who wants spares — will get the best value from the 10, 15, or 20-pack options.
