All-in-one power bank

The WOOJONG 12000mAh power bank integrates a fold-out AC wall plug, a built-in USB-C cable and a built-in iOS cable so you can charge the unit and two devices without packing extra cords. An LED display shows remaining capacity down to 1% and the slim profile measures 5.91 x 2.93 x .72 inch at 7.7 oz.

What the built-ins replace

The integrated AC prongs let you replenish the bank directly from any wall outlet, removing the need for a separate wall charger and cable. The two attached cables cover USB-C and Lightning devices, while an extra USB-A port adds a third output for legacy gear, all supported by 20W Power Delivery fast charging.

Travellers who want cable-free charging

Ideal for business trips or camping where outlet access is limited and carrying multiple cables is impractical. Not suited for users who need higher capacity for multi-day off-grid use, want wireless charging, or require more than three simultaneous device connections.

Questions about this item

How many full phone charges can I expect from the 12000mAh capacity before I need to recharge the power bank itself?

The 12000mAh capacity provides about 2-3 charges for most phones before the power bank needs recharging via the built-in AC plug or USB-C port.

What is the maximum output I can draw continuously from the USB-C port before the power bank limits power delivery?

The USB-C port supports PD20W fast charging, delivering up to 20W for compatible devices until the internal battery depletes.

Does the LED display stay on constantly and generate noticeable heat when the power bank charges devices all day?

The LED digital screen shows battery percentage to 1% accuracy; the slim 0.72 inch profile and 7.7 oz weight help dissipate heat during extended use.
