Magnetic iPhone power bank

The No Sew HX50H3 is a 5500mAh lithium-polymer power bank built for iPhone 12 through 17 series devices. It snaps magnetically to the back of compatible handsets for cable-free charging. A USB-C port handles both input and output so the same cable recharges the pack or powers other gear. The slim profile makes it a practical daily carry for commuters and travellers.

7.5W magnetic wireless output

The single figure that decides fit is the 7.5W magnetic wireless charging rate. It matches the maximum wireless speed supported by the listed iPhone models. If your workflow demands faster wireless charging or a higher total capacity, this unit will not meet that need.

Snap-on design with USB-C flexibility

At .5in thick the pack adds minimal bulk and stays aligned during use. The integrated USB-C port lets you top up the power bank at 5V while simultaneously charging a second device by cable. No separate wall adapter is included, so you will need an existing USB-C charger to replenish the bank between outings.
