Portable power for daily carry

The Ugreen PB536 is a 20000mAh lithium-ion power bank rated at 45W output. It targets commuters and travellers who need to keep a phone, tablet and accessories charged through a full day without hunting for wall sockets.

Sustained output across three ports

With a built-in USB-C cable, a USB-C port and a USB-A port, the unit can power three devices at once. The 45W maximum is shared across active ports, so total throughput holds steady during extended multi-device sessions rather than peaking briefly.

Thermals noise and efficiency

Passive cooling keeps operation silent in normal use. The 7.4V 3A internal configuration supports 45W fast recharge, limiting wall time between trips. At 468 grams the pack stays within typical airline limits for carry-on baggage.

Questions about this item

Does the 45W output generate noticeable heat when charging a phone and tablet together for hours?

The power bank delivers up to 45W across its built-in USB-C cable, USB-C port and USB-A port. Under sustained multi-device loads the aluminium shell disperses heat, so surface temperature stays comfortable during all-day use.

What cables do I need to start using the power bank straight from the box?

A high-strength braided USB-C cable is built in and handles both charging the power bank and powering a device. Only add an extra cable if you want to use the USB-A port or charge a second USB-C device at the same time.

Will the 45W output safely charge an older phone or tablet that only accepts lower power?

Yes. The USB-C ports negotiate the maximum speed each device supports, so legacy gear draws only what it can handle while the power bank caps total output at 45W.
