It's a detail you'll quickly appreciate in everyday use - you don't have to remember about the extra cord, and the powerbank is always ready to go. In addition, fewer accessories in your bag means more convenience - especially when traveling.
Durable automotive-grade cells
The device uses lithium-jonew 21700 automotive-grade cells, which retain up to 80% of capacity after 5 years of use, while standard solutions can drop to about 50%. In addition, Ugreen PB551 supports fast input charging of up to 80 watts. It is possible to fully charge the powerbank's battery in about 1.5 hours using chargers 80 W. That means fewer interruptions and more time to use the devices that are important to you.
Peace of mind and security every day
A comprehensive set of safety features takes care of both the powerbank and connected devices. Protection against over-voltage, over-current, over-charging, over-discharge, zwaRCiem and over-temperature means you can charge your equipment without worry - even during intense, multi-hour use.
