The UGREEN 20000mAh 145W Power Bank with Built-in Cable brings laptop-grade fast charging to a compact, travel-ready body. Its tethered USB-C cable means you never have to dig for a spare cord, while up to 145W of total output lets it top up phones, tablets and even power-hungry laptops in a fraction of the usual time.

Key features & benefits

145W Max Output with 100W USB-C Fast Charging
Charges compatible laptops from empty to a significant charge in about 30 minutes, so you spend less time waiting and more time working.

Built-in USB-C Cable
An always-attached cable means one less cable to pack, find, or lose when you're on the move.

20000mAh / 72Wh High Capacity
Enough energy to recharge a smartphone multiple times or give a laptop a meaningful top-up before the power bank itself needs a recharge.

Multi-Port Output
Built-in USB-C cable plus additional USB-C and USB-A ports let you charge up to three devices at the same time with smart power sharing.

Broad Protocol Support
Compatible with PD, QC and other major fast-charging standards, so it works across iPhone, Samsung, MacBook and more.

Multi-Layer Safety Protection
Built-in safeguards against over-current, over-voltage, overheating and short-circuits protect both your devices and the battery.

Compact, Travel-Friendly Build
Sized to slide into a bag or laptop sleeve without adding bulk, making it easy to carry every day.

LED Battery Indicator
Check remaining capacity at a glance before you head out the door.

How to set up & use

Fully charge the power bank via its USB-C input port before first use. Press the power button to wake it, then connect your device using the built-in USB-C cable or plug into one of the additional ports. The power bank automatically detects each connected device and delivers the optimal charging speed, and the LED indicator shows remaining battery at any time.

Connectivity & compatibility

Works with USB-C and USB-A devices, including iPhone, Samsung Galaxy, MacBook Pro/Air, iPad, Android phones, Steam Deck, Nintendo Switch, wireless earbuds and smartwatches (with a compatible cable).
