Compact 20000mAh power bank for daily travel

The WOOJONG 20000mAh power bank delivers 45W output through a built-in USB-C cable plus additional ports. It charges an iPhone 16 to 70 percent in 25 minutes or an S25 Ultra to 80 percent while supporting simultaneous charging for three devices.

Sustained output across multiple devices

High-density TinyCell chemistry maintains the 45W rate during extended sessions rather than throttling after a short burst. The 20000mAh capacity provides roughly four full phone charges so the unit can power a phone, tablet and accessories through a week of travel on a single recharge.

Check your device charging requirements

Verify that your phone or tablet accepts USB-C power delivery at up to 45W to use the full speed. Ensure you have a compatible wall charger to replenish the power bank itself between trips. The built-in cable cannot be replaced if damaged.

Questions about this item

Does the built-in USB-C cable get hot when the power bank runs at 45W all day?

The 45W output is managed by the internal charging circuit; the integrated cable is rated for the full power delivery and stays within normal operating temperature during continuous use.

What does the buyer need to already own to recharge this 20000mAh unit?

A USB-C wall charger or laptop port that supports USB-C input is required to refill the power bank itself.

Will the 45W output charge an older phone that only accepts 15W?

Yes, the power bank negotiates with each device and will deliver up to 15W to a handset limited to that rate.
