Magnetic iPhone Power Bank

The No Sew B13 is a 10000mAh magnetic power bank built for iPhone 12 through 17 series. It snaps on with 13N ultra-strong magnets and an enlarged contact surface so the charger stays fixed during one-handed selfies or video calls. The slim 4.25×2.75×0.71 in profile weighs only .43 lb and slips into a pocket or small bag for daily commutes and travel.

Dual Wireless and Wired Output

A single USB-C port handles 22.5W input and output for wired fast charging while the magnetic face delivers wireless power at the same time. This means you can charge the power bank itself, top up an iPhone magnetically and feed a second device over cable all from one unit. The bi-directional port removes the need to carry a separate wall charger for the bank.

10000mAh Capacity Rating

The lithium-ion cell stores 10000mAh at 5V which the supplier equates to roughly 1.9 full charges for an iPhone 16 Pro. Wireless fast charging can push an iPhone 16 Pro to 30 percent in 25 minutes. Buyers who need multiple days of reserve or want to power laptops should look at higher-capacity units.

Questions about this item

Can the internal battery be replaced once it no longer holds a full charge?

The battery is sealed inside the case and is not designed to be replaced by the user.

Which limit appears first during continuous charging — thermal protection or the 22.5 W output ceiling?

The 22.5 W USB-C port reaches its rated ceiling before the internal temperature management engages under normal loads.

How warm and loud does the unit get when it powers two devices all day?

It runs silently with no fan; the housing becomes slightly warm during extended dual charging but stays within normal operating temperature.
