Ultra-Slim 5000mAh Magnetic Power Bank
The Coolezx YS01 is a 5000mAh lithium-polymer power bank measuring 0.29 inches thick and weighing 119 grams. It targets iPhone 12 through 17 users who want MagSafe-compatible wireless charging and anyone with a USB-C device needing up to 22.5W wired power. Android phones require a magnetic case for the wireless function to attach securely.
Installation and Common Issues
The power bank snaps onto a compatible iPhone or magnetic case automatically; alignment is handled by the built-in magnets so no manual positioning is needed. Wireless charging stops if the internal temperature rises too high and resumes once the unit cools. Non-magnetic cases, metal objects such as cards or keys between the surfaces, and running multiple heavy apps at once will prevent attachment or trigger thermal shutdown.
Limits of Wireless and USB-C Charging
Magnetic wireless output peaks at 15W while the USB-C port delivers up to 22.5W in both directions. A full 5000mAh charge typically yields 2750mAh to 3250mAh of usable energy for the connected device. Wireless speed drops when heat builds up, so wired USB-C is the faster, more consistent option when time matters.
