WOOJONG

WOOJONG 20000mAh power bank Black

SKU CH-EGBY-B3NXY

A 20000mAh power bank with built-in wall plug, cables and 22.5W fast charging

  • TypePower Bank
  • High 20000mAh capacity powers devices for days
  • 5W fast charging refills phones quickly
  • Built-in folding wall plug and cables eliminate extra gear
  • LED display shows exact remaining charge level
  • Two recharge options: wall plug in 11 hours or cable in 6 hours

What this power bank does

This WOOJONG unit stores 20000mAh of capacity and includes a folding 90-degree AC wall plug, built-in cables and four output ports. It can charge up to three devices at once while an LED display shows the remaining charge level. The 22.5W USB output provides fast charging for compatible phones and tablets.

Charging limits and inputs

Recharging the power bank itself takes 11 hours via the integrated wall plug or 6 hours using a 9V/2A cable connected to the USB-C input. The folding plug design reduces bulk but still requires access to a mains socket. Total output is shared across the active ports so simultaneous charging will split the available current.

What it replaces and when to upgrade

It replaces a separate wall charger, loose cables and a lower-capacity power bank for travellers who want an all-in-one solution. The jump is worth it if you regularly charge multiple devices overnight and prefer not to carry extra accessories. Buyers who need more than 20000mAh or higher single-port wattage should look elsewhere.

Questions about this item

Should I pick the 20000mAh version or a smaller capacity?

The 20000mAh model delivers several full phone charges and measures 5.91 x 2.83 x 1.09 in at 0.81 lb, so choose it when you need multi-day power without carrying extra cables.

What does the 22.5W fast-charging rating mean when I plug in my phone?

The USB port can push up to 22.5W, letting compatible phones charge noticeably faster than standard 5W adapters and cutting the time you wait at the outlet.

How does the built-in wall plug recharge the bank and what speed does it cap at?

Fold out the 90-degree AC plug to recharge the unit directly from mains power; a full refill takes about 11 hours this way, while the 9V/2A cable input does it in roughly 6 hours.
