Core Features & Technology

  • High Battery Capacity: The S39 typically comes in a 50,000mAh or 30,000mAh configuration, making it a "heavy-duty" power station capable of charging a standard smartphone 6 to 10 times.

  • 22.5W / 20W PD Fast Charging: Supports Power Delivery (PD) and Quick Charge (QC 3.0) protocols. It can charge compatible iPhones and Android devices up to 50% in roughly 30 minutes.

  • Multi-Device Charging: Equipped with 3 to 4 output ports (usually 2 USB-A and 1 or 2 USB-C), allowing you to charge a phone, tablet, and earbuds simultaneously.

  • Digital Battery Display: Unlike simple LED dots, the S39 features a clear LED numeric display that shows the exact percentage of power remaining.

  • Emergency LED Flashlight: Includes a built-in high-brightness LED light, which is useful for camping or during power outages.

  • Power Outages: A reliable backup for home use to keep multiple family members' phones charged.

  • Outdoor Activities: Great for camping or hiking due to the built-in flashlight and massive capacity.

Note: Because of its large capacity (above 27,000mAh / 100Wh), this power bank is usually not allowed in airplane carry-on luggage without special airline permission. Always check your airline's Wh (Watt-hour) limits before traveling.
