[Easy Application | 1 to 2 min Installation | No Hassle] Review: Great Magnet for holding phone in place while filming - I bought this for my phone which has a leather case so I can film myself while standing in front of a mirror. I paired it with a suction plate that also has magnets. This is a total game changer. Strong magnet, easy to apply and the adhesive so far stays in place. The quality is great and the magnet is very thin which is great so it does not weigh down my phone. Holds the phone very well in place and works well. Review: Works like a charm!!! - Man, listen... I ripped this thing out of the package so fast it was like Ralphie getting his Red Ryder BB gun on Christmas!! Got my self a new phone and I needed a magnetic tab to stick it up on my holder. So I ordered it, it shows up and this thing is Sleek!! Held it in my fingers and I played the baddest Air Guitar solo in my living room that my neighbors were banging on the wall from how loud the silence was. So, I walk out to take the garbage and decide let's get it going! While sitting there, the hottest chicken in my apartment complex came out and you could just imagine what happened next. She saw me sitting in my car and decided to come walk her Palmerainien near me... it was my chance!!! The magnet gods attracted her to me... she pretended not to see me but I know she did. So she comes over and stands in front my car acting like she's just there to walk her dog and says Heyyyy!! So .. you know, I had to act all Nonchalant and be like Hey. She's like.. what are you doing? I'm like... sticking around.. (Ha!...dad joke). She's like, what'cha got... I'm like... a magnet thing.. She's like.. cool... I'm like yeah.. I know... she steps closer and looks inside. And says oh wow.. that's cool..... (like who could resist a magnet, right?) So she's like wow I need one of those.. I said yeah, well I got it on desertcart.. she says I love desertcart! So I'm like... yeah... (Nonchalant again) So I'm like I got an extra one.. because it came with like 4 in the pack... so she's like oh wow.. (so... now I got the upper hand.. )I say nonchalantly.. you want 1.. she's like yup... so I'm like here ya go.. she takes it and smiles and says.... now you're stuck with me... we both laugh. And then there was this awkward silence.. so I'm like, would you like me to help you with it... she says sure... so I get up and walk to her car... and we peel and stick it. It's perfect for her too... and now, I got her number too!! This became a perfect story of attraction... so I go back inside, my wife saw the whole thing. She's pissed!!! Now, I have to change my phone number, but... the magnetic strip will still stick. So I highly recommend getting it! Just remember, don't let your wife see you talking to the hottest chick in the development. ## Features - [Strong Adhesion] GradCap Magnetic Phone Sticker is using 3M double-sided grade quality sticker and that is why it provides strong adhesive on its back - Keeping your device secure and stable while driving on any road conditions.

Hard plastic with no anti slip or straight to the back of the phone. **Q: Will I still be able to wireless charge with this on the back?** A: That's really depend on where is the spot of your phone provides the wireless feature vs where you are going to put the Metal Plate. It will work as long as the Metal Plate don't block that spot directly. **Q: How do I get a magnet for cell to stay on existing mount?** A: Glad that you ask. These are just Metal Plates. These are not Magnet. You need both to make the mechanism works. Most Phone Car Holder / Phone Cases already come with the built-in Magnet which will automatically work with these Metal plates. If you have any other questions, please let us know again. **Q: Does this work well with outter box** A: Sorry, we can't be 100% sure as the thickness of the phone case can be vary from one to the other. Please be reminded that what we are selling here is just the Metal Plate FOR Magnetic Phone Holder. Therefore, the item we are selling is not a magnet. The strength of the magnet is all depending on its quality. It's nothing much we can control. To cut it short, our metal plates work for nearly all type of magnets.

I actually used these underneath the cabinets above the bed in our RV. I stick small 3 speed fans with magnetic mounts to the metal plates. Works great to hold the small fans in place all night. Just remember, the plates themselves are not magnetic. They are only metal that magnets will stick to. ## Frequently Bought Together - GradCap Metal Plate for Magnetic Phone Car Mount, 4 Packs Universal Ultra Thin Black Metal Disc w/Strong 3M Adhesive Sticker, Replacement Accessory Kit, 2 Rectangle (45x65mm) and 2 Round (40x40mm) - YOSH Car Phone Holder, Magnetic Phone Car Mount Air Vent, Upgraded Strongest Magnets & Super Stable Cradle for Vent, Compatible with iPhone, Samsung, Comes with Metal Plates --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/95322041-gradcap-metal-plate-for-magnetic-phone-mount-4-packs-universal](https://www.desertcart.us/products/95322041-gradcap-metal-plate-for-magnetic-phone-mount-4-packs-universal) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
