Capacity and ports
The WOOJONG J2621 power bank delivers 20000mAh capacity with two USB-C and two USB-A ports. It supports 45W PD 3.0 and QC 4.0 fast charging for compatible phones, tablets and laptops. A built-in LED display shows remaining charge from 0 to 100 percent.
Charging limits
Maximum output is 45W so devices needing more power will charge slower or not at all. Recharging the bank itself takes about two hours only when a 45W PD charger or higher is used, and that charger is not included. Four devices can be connected simultaneously but total output is shared across all ports.
Single deciding spec
The 45W PD 3.0 rating determines whether this unit can fast-charge your specific laptop or tablet. If your device requires a higher wattage profile this power bank will fall back to a lower rate. Buyers who need 60W or 100W USB-C charging should look elsewhere.

Questions about this item
Should I pick the 20000mAh version or a smaller capacity?
The 20000mAh J2621 can fully charge a MacBook 14 about 1.05 times, an iPhone 15 Pro from 0 to 60% in 30 minutes, and power four devices simultaneously through two USB-C and two USB-A ports.
What does the 45W PD 3.0 rating deliver in daily use?
It charges an iPhone 15 Pro to 60% in 30 minutes and recharges the power bank itself in two hours when paired with a 45W PD charger.
How do the USB-C PD 3.0 and USB-A QC 4.0 ports limit real-world speed?
Each USB-C port supports up to 45W PD 3.0 output, while the USB-A ports run QC 4.0; total shared output is capped at the bank's 45W maximum, so simultaneous charging splits that budget.
