Capacity and Purpose

The WOOJONG power bank stores 20000mAh of energy and includes built-in cables plus a fold-out wall plug. It targets travellers, field staff and outdoor users who need several days of phone or tablet power without carrying separate chargers or hunting for free sockets.

Charging Interface Limits

The unit delivers up to 20W through USB-C Power Delivery and Quick Charge protocols. It accepts 100-240V AC input directly from the integrated plug so no extra adapter is required worldwide. Output is limited to the single USB-C port and the attached cables; there are no additional ports for simultaneous multi-device charging.

Deciding Specification

The 20000mAh capacity yields roughly 2.56 full charges for an iPhone 16 Pro Max, 2.71 for an iPhone 15 Pro Max, 1.55 for an iPad 10th Gen and 2.4 for a Galaxy S24 Ultra. Buyers who need more stored energy or the ability to charge a laptop will find this capacity insufficient.
