Xiaomi Launches 10000mAh 55W Power Bank with 70cm Retractable USB-C Cable, Smart Color Display, and 45W Rapid Recharging

Eliminating the daily hassle of carrying tangled cables and hunting for wall adapters, Xiaomi has officially introduced an all-in-one charging accessory on its Youpin platform in China: the Xiaomi 10000mAh 55W Power Bank (model number NPB1055R).

Priced at 299 yuan (approximately $45 / ~₹3,550), the compact charging hub is built around a versatile 70cm built-in retractable USB-C cable, high-speed 55W Power Delivery and PPS/AVS output, and a hidden color smart display that tracks real-time operating parameters. The accessory combines high-capacity lithium-ion cells with 45W rapid two-way recharging, positioning itself as an essential pocket companion for smartphone, tablet, and ultrabook users on the move.

70cm Retractable USB-C Cable: No More Tangled Wires

The primary engineering breakthrough of the NPB1055R is its integrated cable management system:

• Integrated 70cm Retractable Mechanism: Mounted neatly into the top curved rim of the power bank is a 70cm flat USB-C cable. Users can pull the connector out to their preferred working length (with multiple ratcheting locking positions) and retract it back into the unibody housing with a gentle tug.
• Streamlined Portability: By embedding the cable directly into the body, users no longer need to carry loose charging cords in their backpacks or pockets, preventing connector bending and cable fraying.
• Ergonomic Rounded Footprint: Despite incorporating the spring-loaded recoil spool and 10,000mAh battery cells, the power bank measures just 90 × 50 × 41 mm and weighs 260 grams, sporting smooth, rounded contours designed for single-handed comfort.

Multi-Port Matrix: 55W Dual USB-C & Universal Protocol Support

Beyond the integrated retractable cable, the power bank is equipped with two additional physical ports at the bottom, allowing flexible multi-device powering:

• 55W High-Speed Output: Both the integrated retractable USB-C cable and the standalone bottom USB-C port deliver up to 55W max output, supporting universal USB-PD (Power Delivery), PPS (Programmable Power Supply), and AVS (Adjustable Voltage Supply) protocols.
• 22.5W USB-A Port: A standard USB-A port supports up to 22.5W output for legacy smartphones, smart fitness bands, and low-power IoT accessories.
• Simultaneous 3-Device Charging: Users can charge up to three devices concurrently (via the retractable cable, secondary USB-C port, and USB-A port). When multiple outputs are engaged simultaneously, the device automatically engages dynamic power sharing capped at a stable 15W total output.
• 45W Rapid Two-Way Recharging: Recharging the power bank itself is equally rapid; either USB-C connection accepts up to 45W fast input, fully replenishing the 10,000mAh cell in under 1.5 hours with a compatible wall charger.

Charging Benchmarks: Real-World Device Performance

According to official laboratory testing published by Xiaomi, the 55W power output delivers rapid battery top-ups across mainstream consumer hardware:

• Xiaomi 17 Pro: Reaches 67% charge in just 30 minutes (delivering approximately one full recharge cycle).
• Apple iPhone 17 Pro: Reaches 64% charge in 30 minutes (providing roughly 1.3 full charges from empty).
• Apple iPad Air 11-inch (M3): Tops up to 33% battery capacity in 30 minutes.
• Ultrabook Support: Capable of trickle-charging lightweight USB-C laptops, Nintendo Switch consoles, and wireless headphones supporting USB Power Delivery standards.

Smart Hidden Color Screen & Advanced Safety Engineering

Setting it apart from standard power banks that rely on four blinking LED dots, the NPB1055R features an integrated color digital display seamlessly embedded beneath the front matte translucent shell:

• Real-Time Wattage & Metrics: The display illuminates to provide exact remaining battery percentage, real-time output/input charging wattage, and current operating temperature.
• Health & Cycle Telemetry: Advanced diagnostic screens display cumulative battery cycle counts and overall cell health status, giving tech enthusiasts transparent insight into long-term battery degradation.
• Rigorous Safety Certifications: The internal lithium-ion battery cells have undergone stringent durability certifications-successfully completing nail penetration tests, enduring 14kN of mechanical compression pressure, and surviving 135°C high-temperature thermal chamber exposure for one hour.
• Nine-Layer Circuit Safeguards: Comprehensive protection hardware defends connected devices against overvoltage, overcurrent, overcharging, over-discharging, short circuits, and electrostatic discharge.

Colorways, Pricing, and Global Availability

The Xiaomi 10000mAh 55W Power Bank is currently available on Xiaomi Youpin and authorized Chinese e-commerce retailers in three metallic-inspired colorways:

• Deep Titanium
• Titanium Gold
• Iris Purple

Priced at 299 yuan (~$45 / ~₹3,550), the power bank carries a modest premium over standard wired bricks, justified by its mechanical retractable 70cm cable, 55W multi-protocol output, and comprehensive smart diagnostic display. While Xiaomi has not officially announced an international launch schedule, the brand’s popular charging peripherals frequently transition to global markets-including India, Southeast Asia, and Europe-under Xiaomi’s global ecosystem banner within three to six months.
