I have Samsung S23 Ultra, and the MagSafe case I use has raised edges to protect the camera lenses. These raised edges interfere slightly with the magnetic connection...but it works great. The battery gets a little warm when in use on the phone, but I love the "kickstand" (just used for watching vids on the plane), and the ability to charge the battery while the battery is charging the phone is a great feature. Highly recommend this for anyone that can use MagSafe charger. The capacity isn't has high as some, but the purpose is to have a nice backup in a small form factor, and this is a great solution (I have 3 other external batteries, and this is now my go-to for portability).

The xCool 5,000mAh Ultra-Slim Magnetic Wireless Power Bank is fantastic. It's sleek, easy to carry, and the magnetic feature is super convenient. I love that it comes with a USB-C cable, making it versatile for different devices. The power bank charges my phone quickly and has been a lifesaver on many occasions. Highly recommend!

Very slim charger hard to tell it is even on your phone

It’s a monster cable very powerful and it’s also the most very fastest charger. Fast go get one.
