The magnet is strong and holds the iphone mini with the magsafe case great. Charges fairly fast. Didn’t work to well with a s24 ultra though, slower charging and got much warmer than with the iphone mini. Worth the money if your charging the iphone in a magsafe case.

I really liked this but it is already bubbling on the face and looks very weird.**UPDATE** ESR contacted me to get me an updated charger! Great customer service!

Absolutely love this device for my car. the clip is super strong and the magnet is the best. Work perfectly, and I bought it for my husband, he absolutely love it.

This is so great. Plug it in and then just set your iPhone on it to charge. Magnet is great. I understand it doesn’t work with all models but if you have one that can accept this type of charge … go for it

This car charger does a solid job of keeping my phone charged while I drive. The magnetic hold is strong, and it stays in place, even on bumpy roads. Plus, the cooling feature is a nice touch for longer trips.

They charge very well, the magnets are extremely strong, the vent mount is solid, and the integrated CryoBoost cooling really does help keep temps down so that your iPhone doesn’t enter the "too hot to charge" zone. That used to frequently happen on summer road trips, where the sun would be beaming in the front windshield, and the combination of that direct sunlight, plus the phone charging, plus the phone being used for battery intensive tasks like GPS navigation meant the phone would get hot VERY easily. This helps avoid that really well, which I’m sure also helps maintain good battery health. I’d like to not have to replace my iPhone so frequently, but replacing the battery is rarely worth it, and my phones routinely end up at 75%-ish life after just a couple years of use. And I’m sure that 75% is optimistic, too- once it gets to those levels, it really feels more like 50% even if the number says 75%.

I would like to know this product doesn’t have USB C to USB A adapter, I have to buy adapter and power charger to use.

I like this charger. I was skeptical about its ability to stay put, but works well. The cooling feature may be beneficial in winter when the heat is on, but it’s not needed during summer or when the AC is on. I would buy this again, and I recommend it. Wish the LED matched my dash (green) but a minor issue.

I have bought cryoboost ESR chargers for all my four cars, my office, my wife’s office, my mother, my mother‘s car, friends, families. This new Qi2 with cryoboost is my favorite, and in my opinion, they should be the only thing they should be selling and marketing for iPhones I don’t know why it’s currently unavailable, but I really wanted to come back in stock

The 15W MagSafe Car Mount Charger with CryoBoost is Qi-2 Certified and provides a secure hold on your phone, preventing any movement. It efficiently charges my Pixel 9 Pro and attaches securely to your car vent, especially with the added brace. The integrated fan helps keep the phone cool during charging. The only improvement I would suggest is the addition of an on/off switch to control the charger.
