WOOJONG 20000mAh power bank with wall plug

The WOOJONG power bank packs a 20000mAh lithium-ion cell into a 5.90 x 2.67 x 1.02 inch frame weighing 12.8 oz. It integrates a fold-out AC plug, a built-in USB-C cable and a built-in phone cable so no extra cords are required. Two input methods and five simultaneous outputs cover phones, tablets and other USB devices.

Travellers who want one device to recharge itself

Users who prefer a single unit that plugs directly into a wall outlet and carries its own cables will find this convenient. Buyers who need wireless charging, a higher total output wattage than the stated 22.5W maximum, or a slimmer profile for a minimalist pocket carry should look at something else.

20000mAh capacity with real-world device estimates

The bank delivers roughly 3.2 full charges for a Phone 15 Pro Max, 2.8 for a Galaxy S22 Ultra, 3.2 for a P50 Pro and 2.6 for a Pad mini 6. Recharging the bank itself takes 10 hours via the AC plug or 6 hours through the USB-C port, while the digital display shows remaining power at a glance.

Questions about this item

Does this power bank include its own AC plug so I don't need a separate wall adapter to recharge it?

Yes, the unit has a built-in AC wall plug that lets you recharge the 20000mAh battery directly from a mains outlet without carrying an extra adapter or cord.

Can I still use the built-in USB-C cable to charge an older phone that only supports standard 5V charging?

The integrated USB-C cable supports 18W Power Delivery and will negotiate down to 5V for older devices, so it charges legacy phones safely at their maximum supported rate.

How do I confirm the power bank is actually delivering fast charge to my phone after I plug it in?

The smart LED digital screen shows the remaining capacity in real time; when a compatible phone draws 18W or 22.5W you will see the percentage drop noticeably faster than with a standard charger.
