Key Features

• Built-in 28-Inch Retractable USB-C Cable: No more fumbling for cables or dealing with tangles. Simply pull out the built-in cable when needed and retract it neatly after use. This feature keeps your backpack, desk, or travel bag organized, making it ideal for students, professionals, and travelers who value efficiency and cleanliness.
• 35W Fast Charging with PD Protocol Support: Experience rapid charging that delivers up to 65% battery to an iPhone 17 Pro Max in just 30 minutes. This high-speed performance reduces downtime significantly, whether you’re rushing to a meeting, catching up on emails during a flight, or enjoying uninterrupted gaming or streaming. Compatible with all major USB-C devices, including iPhones, Samsung Galaxy phones, Google Pixels, iPads, and more.
• Intelligent Dual-Device Charging System: When plugged into a wall outlet, the power bank automatically manages power distribution between your device and itself. Initially, it supplies peak 34–35W to your phone (ideal for 0–30% battery levels), then uses any excess power to recharge its internal 10000mAh capacity based on usage patterns. This smart system ensures optimal charging efficiency without manual adjustments.
• Integrated Wall Plug for Effortless Charging: Say goodbye to carrying bulky chargers. The built-in plug allows direct connection to any standard wall outlet, enabling simultaneous charging of both your gadget and the power bank. Perfect for hotel rooms, bedside tables, or office desks—just plug it in and let it work while you sleep or relax.
• Dual Safety Certifications & Comprehensive Protection: Backed by FCC (U.S. electromagnetic compatibility) and UL (U.S. safety) certifications, this product undergoes rigorous testing for reliability and safety. Constructed with flame-retardant ABS material and premium battery cells, it includes short circuit, overcharge, and overload protection circuits. These features allow safe overnight charging without supervision, giving you peace of mind.
• 10000mAh Capacity with Real-World Performance: While the nominal capacity is 10000mAh, industry-standard voltage conversion and heat loss mean actual usable energy ranges between 6500–7500mAh. This translates to approximately 1.5 full charges for an iPhone 17 Pro Max or 1.2 charges for a Samsung S24 Ultra. Ideal for daily commutes, travel, or backup power during emergencies.

Important Notes

• Actual usable capacity may vary slightly due to standard industry voltage conversion losses and minor heat dissipation during charging cycles. Expect 6500–7500mAh usable energy from the rated 10000mAh.
• Maximum 35W fast charging applies primarily during initial battery phases (0–30%). Slower rates occur as devices approach full charge, which is normal and safe.
• For best results and safety, always use the included built-in USB-C cable. Third-party cables may not support PD protocols and could reduce charging speed or damage devices.
• Safety protections allow unattended overnight charging, but avoid exposing the unit to extreme temperatures, water, or physical impacts.
• The package contains only one HOU 3 in 1 Portable Power Bank. Accessories like additional cables or wall adapters are not included unless shown in product images (see ).
