Long Description

Stay powered wherever you go with the J103 Discovery Edition 10000mAh Power Bank. Built for everyday use, it delivers up to 22.5W fast charging and supports many popular fast-charge standards, including PD3.0/PD20W, QC3.0/QC2.0, FCP, SCP, AFC, VOOC, DASH, and more. This makes it a great match for a wide range of phones, tablets, and other USB devices.

The power bank includes a practical port setup for charging multiple devices: two USB-A outputs (up to 22.5W max each) and one USB-C output (up to 20W max). It also recharges through USB-C input up to 18W, helping reduce downtime between uses. A clear LED digital display shows remaining battery level, and a green indicator confirms when PD/QC fast charging is active.

Made with an ABS + PC flame-retardant shell and a lithium polymer battery, it’s designed for durability and safe daily carry. Compact but powerful, the J103 is ideal for commuting, school, travel, and backup charging when you need it most.
