INIU Launches Pocket Rocket P50 – The World’s Smallest 10,000mAh 45W Fast-Charging Power Bank.

Ultra-compact design with 45W PD charging, triple-device support, industry-first TinyCell Pro technology and an integrated detachable lanyard cable deliver powerful portability for travel, study, and work.

INIU, the global portable charging brand trusted by over 38 million users worldwide, has announced the launch of the all-new Pocket Rocket P50, redefining fast-charging portability with its smallest-ever 10,000mAh 45W PD power bank. Measuring just 3.3 × 2.0 × 1.0 inches (8.3 × 5.2 × 2.6 cm) and weighing only 5.6 oz (160 g), the P50 is approximately 45% smaller than a standard 10,000mAh power bank—compact enough to slip into a pocket, handbag, or travel pouch while delivering full-speed charging performance.

The Pocket Rocket P50 offers 45W full-speed output that supports PD, QC and Samsung Super Fast Charging 2.0 (PPS), with the ability to charge multiple devices simultaneously. This power level can take a smartphone from low battery to around 73% in just 25 minutes and deliver roughly 42% charge to a MacBook Air in the same time, making the P50 a practical emergency laptop solution as well as a daily phone charger. Equipped with USB-C in/out plus USB-A connectivity, the unit supports simultaneous input and output for flexible charging scenarios.

At the heart of the P50 is INIU’s industry-first TinyCell Pro battery technology, combined with a multi-tab cell architecture for improved heat control, faster charging efficiency, and extended battery lifespan. A high-performance NVIDIA-grade inductor permits a remarkably small and light form factor without sacrificing capability, while an ultra-thin 0.5mm Genius Display provides real-time power status. The P50 incorporates 18 layers of advanced safety protection to defend against overheating, overcharging, short circuits, and other common risks, delivering SAFE Fast Charge Pro performance backed by INIU’s rigorous quality testing.

Portability and convenience are central to the design: the P50 ships with a detachable lanyard-integrated USB-C cable that serves for both charging and recharging. The cable has passed more than 11,000 bend tests and includes an E-Marker chip to ensure stable performance and broad compatibility. With a 10,000mAh capacity, the Pocket Rocket P50 can deliver roughly two full charges to an iPhone 16, 1.5 charges to a Samsung S24, or 1.5 charges to an iPad mini—ideal for commuters, students, short trips, and business travel. The power bank is airline-approved for carry-on use.

Available now in the USA for $32.99 (RRP $38.99) on Amazon US and in the UK at an RRP of £38.99 (with an additional 20% discount available using code KVUWY7I4 on Amazon UK), the Pocket Rocket P50 continues INIU’s mission to combine cutting-edge technology with practical, portable design. The in-box package includes the INIU Carry P50-E1 Power Bank (with the lanyard-integrated USB-C cable) and a user manual.

Since its founding in 2014, INIU has specialised in high-quality portable power solutions and has garnered international recognition — including the iF Design Award, Red Dot Award and CES Innovation Award. The Pocket Rocket P50 represents a technological step forward in the brand’s ongoing commitment to deliver safe, stylish and performance-driven charging gear for modern mobile lifestyles, backed by INIU’s industry-leading support and warranty provisions.
