Power bank capacity and purpose

The WOOJONG 20000mAh power bank delivers 35W super fast charging for phones and other USB devices. It supports PD 3.0 and QC 4.0 protocols to charge a Phone 16 from 0 to 61% or an S22 Ultra from 0 to 40.9% in 30 minutes. The integrated digital display shows remaining capacity at a glance.

Connectors and daily use

Two USB-A outputs and two Type-C ports provide four simultaneous outputs with bi-directional charging on the Type-C ports. The included C-to-C cable lets the bank recharge itself in 3 hours while also powering a Phone 16 in 2 hours. Double-tap the button to enable trickle charging mode for small gadgets such as headphones and smartwatches.

Upgrade context and limits

This unit replaces lower-capacity packs that cannot sustain multiple devices or higher-wattage fast charging. It is not suited for users who need laptop-level power delivery beyond 35W or who require wireless charging capability. Airline-safe certification makes it viable for carry-on travel without restrictions.
