UGREEN 10,000mAh 20W Power Bank, Two-Way Fast Charging for Portable Device Power
Product Description
The UGREEN PB311 is a 10000mAh power bank with 20W two-way fast charging. The same USB-C port charges your phone at up to 20W and recharges the power bank itself, so one cable is enough for daily use.
A flat phone halfway through the day, or a power cut at the wrong moment, means missed calls, M-Pesa messages and lost work. The UGREEN PB311 power bank stores 10,000mAh and charges at up to 20W, so you can top up wherever you are. It is made for commuters, students, travellers and remote workers who cannot always reach a socket.
Key Features and Benefits
- Battery capacity: 10,000mAh. Capacity gives you a rough idea of how many times a phone can be recharged; actual results depend on your phone battery.
- Charging power: Up to 20W output. Your device and cable must support the same charging speed.
- Two-way charging: Charges your devices out and can itself be recharged through the same fast-charging port.

- 20W fast charging: a quick top-up for phones that support USB Power Delivery.
- Two-way USB-C: the same port is used for charging out and for recharging the power bank.
- Everyday carry: small enough for a bag or jacket pocket.
Made for Life in Nairobi and Across Kenya
