Ultra-Slim Magnetic Power Bank

The WOOJONG M3 is a 12800mAh portable charger built for travellers who need cable-free charging. Its 0.4 profile slips into a pocket while the integrated lanyard cable handles both input and output. MagSafe alignment keeps iPhone 12 through 17 models locked in place during wireless charging.

22.5 W Wired and 15 W Wireless Output

The single figure that decides fit is the combined 22.5 W wired and 15 W wireless delivery. If your phone accepts that rate you gain rapid top-ups; devices limited to slower protocols will not draw more power. No other charging standard or wattage is provided by this unit.

Built-In Cable and Strap Replace Loose Leads

The USB-C tether doubles as a carry strap so there is no separate cable to lose or forget. It recharges the bank and powers connected gear without extra accessories. Android users without magnetic backs lose the snap-on convenience but still use the wired port.

Questions about this item

The integrated USB-C cable delivers up to 22.5W wired fast charging, while the magnetic surface provides up to 15W wireless fast charging for MagSafe-compatible iPhones and other Qi-enabled devices.

How does the 0.4 ultra-slim profile affect pocket or bag fit?

At 0.4 ultra-slim thickness the unit slips easily into a shirt pocket or slim bag compartment, and the built-in USB-C cable doubles as a lanyard so it can also be worn around the neck or clipped to a strap.
