The INIU 45W 10,000mAh Portable Charger (Model P55L) establishes a new benchmark for pocket-sized fast-charging performance by packing an immense 45W of USB-C Power Delivery into a chassis roughly the size of a credit card deck. Designed specifically for modern multi-device users who carry power-hungry smartphones, iPads, and even Steam Decks or ultrabooks, this compact powerhouse delivers full-throttle charging speeds that typically require a bulky multi-pound battery block.

Constructed with INIU's high-density TinyCell battery architecture and reinforced by impact-resistant aerospace polycarbonate, the P55L features an integrated, flexible USB-C silicone cable that wraps securely into the frame to act as a convenient finger carry strap. An integrated LED digital battery display gives an instant numerical readout of remaining capacity, while a built-in emergency LED flashlight provides practical utility during power outages, night walks, or outdoor adventures.

With Samsung Super Fast Charging 2.0 (45W PPS) and PD 3.0 protocol support, the INIU P55L refuels a Galaxy S24 Ultra or S25 Ultra at its maximum theoretical wired speed, reaching 70% in just 35 minutes. Its 37Wh rated energy is well beneath the TSA 100Wh carry-on flight restriction, while INIU's proprietary 15-layer SmartProtect thermal chip guards continuously against over-voltage, short-circuits, and excessive operational heat.
