The HOCO J121A Fast is a 20000mAh high-capacity power bank built for everyday fast charging. It supports PD 20W via Type-C and 22.5W on both USB-A ports with multi-protocol compatibility (QC3.0/FCP/SCP/AFC)—so your Android or iPhone can top up quickly and safely. A clear LED digital display shows remaining power at a glance, and a green indicator lights up when PD/QC fast charge is active. With dual inputs (Type-C/Micro-USB at 18W), you can recharge the pack conveniently, while the ABS+PC flame-retardant shell and lithium-polymer cells ensure reliable performance for travel, office, or emergency use.
