20000mAh 45W portable charger

The NOBIS ZWPBWWA-202C2A45W power bank stores 20000 milliamp_hours in a lithium-polymer cell and delivers up to 45 watts through two USB-C ports that support both input and output. Two additional USB-A ports bring the total to four simultaneous outputs. A built-in LED digital display shows remaining capacity from 0 to 100 percent. The green housing weighs 392 grams and measures 13.7 in x 7.0 in x 2.63 in.

Four-device charging with dual-role USB-C

Both USB-C ports accept up to 45W for recharging the power bank itself and can supply up to 45W to connected gear, so a single cable type handles both directions. The two USB-A ports add legacy compatibility for older cables. Together the four ports let a phone, tablet, laptop and accessory charge at once without needing a wall outlet or a second charger.

Sustained 45W output under continuous load

The 45W rating applies to continuous delivery rather than a brief burst, so a MacBook Pro 14 inch can reach 47 percent in 30 minutes and an iPhone 15 Pro can reach 60 percent in the same window while the bank maintains its output. Recharging the bank at 45W completes a full cycle in roughly two hours. The 5 volt 3 amp baseline ensures stable power for lower-draw devices such as earbuds or smartwatches without voltage sag.

Questions about this item

How long can the 45W output run continuously before the 20000mAh capacity is depleted?

At full 45W draw the 20000mAh cell lasts roughly 2 hours, matching the quoted 2-hour recharge time at 45W input

Does the unit get hot or noisy when all four ports are used for a full day?

The power bank has no fan; it relies on passive cooling, so it stays silent and warm but not hot during extended multi-port use

What cable is required to reach the 45W two-way fast charge rate?

A USB-C to USB-C cable rated for 45W Power Delivery is needed; the power bank itself provides both Type-C ports for input and output
