Thanks to a powerful USB-C output of up to 100W, the UGREEN PB551 can easily handle demanding devices such as laptops. It can charge a MacBook Pro 16" from 0% to 43% in just 30 minutes, making it a great companion when every minute counts. There is also a low-current mode, so it works just as well with smaller gadgets like TWS earbuds, smartwatches, and other low-power accessories.

One Power Source for Multiple Devices

The UGREEN PB551 is designed to fit the way you actually use your tech. It supports 1-port, 2-port, and 3-port charging setups, so you can power several devices at the same time with smart power distribution. Charge your laptop and smartphone together or top up a few smaller devices without having to choose what matters most right now.

Built-In USB-C Cable for Everyday Convenience

The integrated 18cm USB-C cable also works as a handy carrying strap. It is a small detail that makes a big difference in everyday use. No need to remember an extra cable, no extra clutter in your bag, and your power bank is always ready when you need it. That means more convenience at home, at work, and especially while traveling.

Durable Automotive-Grade Battery Cells

This model uses automotive-grade 21700 lithium-ion cells designed for long-term reliability. After 5 years of use, they can retain up to 80% of their capacity, while standard cells may drop to around 50%. The power bank also supports up to 80W fast input, allowing you to recharge it fully in about 1.5 hours with a compatible 80W charger. Less waiting, more time using the devices you care about.

Safe, Stable Charging Every Day

A full range of safety protections helps protect both the power bank and your connected devices. Protection against overvoltage, overcurrent, overcharging, over-discharging, short circuits, and overheating gives you extra peace of mind, even during long and intensive charging sessions.

Travel-Ready for Work and Everyday Adventures

Compact dimensions of 139 × 80 × 26.7 mm, a weight of 450g, and pass-through charging support make the UGREEN PB551 a smart choice for trains, hotels, airports, and everyday commuting. Its 72Wh energy rating meets common carry-on air travel requirements for batteries under 100Wh, so you can bring it on board and keep your essential devices powered during the trip.
