20 000 mAh 45 W power bank

The WOOJONG J2621 is a 20 000 mAh portable charger that delivers up to 45 W through two USB-C ports and 30 W through two USB-A ports. An LED digital display shows the remaining capacity so you can plan recharges. It is built for users who need to keep a laptop, phone and accessories powered during a day away from mains power.

Replaces bulky single-port chargers

If you currently carry separate bricks for a MacBook and a phone, this unit consolidates them into one pack that can charge four devices simultaneously. The jump is worth it when you regularly drain a phone and a laptop on the same trip and want to cut the number of cables and adapters in your bag.

Suits multi-device commuters and travellers

It fits professionals who move between meetings, students with a laptop and tablet, or anyone running a Steam Deck alongside a phone. Buyers who only ever charge one low-power handset at a time will find the extra ports and 45 W output unnecessary for their needs.
