Compact power banks are widely available, but the Iniu P55-E2 portable charger distinguishes itself with its blend of size and power. During Amazon’s recent October Prime Day, the price dropped, but a new discount has reduced it further. Currently, it’s available on Amazon in black for just $13.74, thanks to an automatic 45% off coupon applied at checkout.

Though not as compact or lightweight as the Verge-endorsed Iniu Pocket Rocket P50, the P55-E2 boasts a sleek design and a robust 10,000mAh battery. It supports charging speeds up to 45W through one of its USB-C ports, enabling quick charging for smartphones, tablets, and gaming devices like the Nintendo Switch 2. Equipped with three USB ports (two USB-C and one USB-A), it can charge three devices simultaneously.

Beyond its impressive size and capacity, the P55-E2 includes several features that enhance its value. It has a display that indicates the remaining charge in real time and supports pass-through charging, allowing you to charge both the power bank and a connected device simultaneously. Additionally, its detachable lanyard serves as a USB-C cable, providing everything needed for immediate charging.

Update, October 20th, 2:50PM ET: We have clarified that this discount pertains to the Iniu P55-E2, not the smaller P50, known as the “Pocket Rocket.” Despite both models having a 10,000mAh capacity and 45W top charging speed, the P55 is slightly larger and heavier than the P50, though it remains quite compact.
