INIU has introduced the Pocket Rocket P50, a compact yet powerful 10,000mAh power bank that the company claims is the world’s smallest with 45W Power Delivery (PD) fast-charging capability. Designed for portability without compromising performance, the P50 weighs just 160g and measures 8.3 × 5.2 × 2.6 cm — roughly 45% smaller than most 10,000mAh power banks.
The P50 supports PD, QC, and Samsung Super Fast Charging 2.0 (PPS), allowing it to deliver up to 45W output to charge multiple devices at once. INIU says it can power a smartphone from low battery to around 73% in 25 minutes, and add roughly 42% to a MacBook Air in the same time, making it suitable for both mobile devices and light laptop use. It features both USB-C in/out and USB-A ports, with the ability to charge while recharging.
At its core is INIU’s proprietary TinyCell Pro technology, which uses a multi-tab cell architecture to improve heat control, enhance charging efficiency, and extend battery life. A high-grade inductor — typically found in NVIDIA hardware — enables the power bank’s small size, while an ultra-thin display provides real-time power status. The P50 also includes 18 layers of safety protection against overheating, overcharging, and short circuits.
For added convenience, the device comes with a detachable lanyard-integrated USB-C cable that works for both charging and recharging. The cable, tested for over 11,000 bends, includes an E-Marker chip for stable performance and wide compatibility. With its 10,000mAh capacity, the P50 can deliver up to two full charges for an iPhone 16, 1.5 charges for a Samsung S24, or an iPad mini, and is approved for airline carry-on.
The INIU Pocket Rocket P50 is available now in the US for $32.99.
