The Griffin Ultra Slim Magnetic Power Bank is a slim battery pack that snaps onto a MagSafe-style phone and charges wirelessly, with a 20W USB-C PD port for wired charging of phones, earbuds or other USB-C devices. Its magnetic alignment keeps the pack centered on the back of the phone, and the thin body is meant for a pocket or small bag. At $25.49 at CVS Pharmacy as of November 7, 2026, it is the lowest of the three store prices and a low entry point for a magnetic wireless pack.
