20000mAh 45W power bank with four ports

The NOBIS ZWPBWWA-202C2A45W is a 20000mAh lithium polymer power bank that delivers up to 45W output. It features two USB-C ports and two USB-A ports for charging four devices at once. A built-in digital display shows remaining capacity from 0 to 100 percent. The unit comes in green and includes a USB-C to USB-C cable.

Suited for multi-device users needing laptop power

This bank suits travellers and commuters who must charge a laptop, phone, tablet and wearables together. It supports PD 3.0 and QC 4.0 protocols for fast charging compatible devices. Buyers who only need occasional phone top-ups may find the capacity and weight excessive. Those requiring more than four simultaneous ports should look elsewhere.

Check your device charging requirements first

Verify that your laptop or other high-draw device accepts 45W or less via USB-C PD. Confirm your cables support the required current for fast charging. The bank recharges at up to 45W input, so a compatible charger is needed for the claimed two-hour refill. Ensure the 13.7 by 7.0 by 2.63 inch dimensions fit your bag.

Questions about this item

What cables do I need to use the USB-C ports on this power bank?

The unit includes a USB-C to USB-C cable. For USB-A devices you must supply your own USB-A cable.

Will the 45W output charge a laptop that only accepts 30W over USB-C?

Yes. The power bank negotiates PD 3.0 and QC 4.0 so it will deliver only the 30W your laptop requests.

How do I confirm the power bank is delivering fast charge to my phone?

The built-in LED digital display shows the remaining capacity from 0 to 100% and updates in real time while charging.
