UGREEN PB551 Power Bank (20,000 mAh, 145W, retractable cable)

The UGREEN PB551 is a power bank designed for people who don't want to choose between mobility and performance. With a capacity of 20,000 mAh, a maximum output power of up to 145 W, fast charging at 100 W, a built-in USB-C cable, a smart digital display, and the ability to charge multiple devices simultaneously, it is a reliable power hub for work, travel, and everyday use. Whether you're working on a train, flying on a plane, or just want to ensure your devices are ready to go – this power bank won't let you down.

Laptop, tablet, and smartphone ready to go.

Thanks to a single USB-C port with a power output of up to 100 W, the power bank easily recharges demanding devices such as laptops. You can charge a MacBook Pro 16″ from 0 to 43% in just 30 minutes. A special low power mode ensures that the power bank works perfectly with low-energy devices, such as TWS headphones or smartwatches. It’s a reliable support when time is of the essence – during business trips, between meetings, or while working outside the office.

One energy source for multiple devices.

The UGREEN PB551 power bank has been designed to flexibly adapt to your electronic usage style. It supports 1-, 2-, and 3-port configurations, allowing simultaneous charging of multiple devices with appropriate power distribution. This means you can recharge your laptop and phone at the same time or top up several smaller devices without having to choose which one is more important at the moment.

Built-in USB-C cable

The integrated 18 cm USB-C cable also serves as a practical lanyard. This is a detail that you will quickly appreciate in everyday use – you don't have to remember to bring an extra cable, and the power bank is always ready to work. Moreover, fewer accessories in your bag means more convenience – especially when traveling.

Durable automotive class batteries

The device uses lithium-ion 21700 automotive-grade cells, which retain up to 80% capacity after 5 years of use, while standard solutions may drop to around 50%. Additionally, the UGREEN PB551 supports fast input charging of up to 80 W. There is the possibility to fully charge the power bank battery in about 1.5 hours using an 80 W charger. This means fewer interruptions and more time to use the devices that are important to you.

Calm and safety every day.

The comprehensive set of protections takes care of both the power bank and the connected devices. Protection against overvoltage, overcurrent, overcharging, excessive discharging, short circuits, and overheating ensures that you can charge your equipment without worries – even during intense, hours-long usage.

Ready for travel – both business and personal.

The compact design (139 × 80 × 26.7 mm), lightweight (450 g), and the ability to use the power bank while it is charging make the UGREEN PB551 ideal for use on trains or in hotels. With an energy capacity of 72 Wh, it meets the aviation standards for carry-on luggage (below 100 Wh), allowing you to easily take it on board and have access to power even during the flight.
