20000 mAh portable charger

The WOOJONG power bank stores 20000 mAh of energy and delivers up to 15 W through its USB-C port. Two additional USB-A ports provide up to 12 W each for simultaneous charging. A short USB-C to USB-A cable is included so the unit works straight from the box.

15 W USB-C output

The single USB-C port shares a maximum of 15 W across connected devices, which decides whether the bank can fast-charge a particular phone or tablet. Two USB-A ports add 12 W each for older cables. Total output is split when three devices draw power at once.

Thermal and power behaviour

The pack uses overcharge protection to stop charging when full, limiting heat build-up during normal use. No fan is present, so operation stays silent. LED indicator lights show remaining capacity without adding measurable power draw.
