Designed for people who value mobility, safety, and convenience, this model combines dual-wire input/output functionality, high solar efficiency, and a massive 20000mAh capacity — ensuring your devices stay powered when you need them most.

Dual-Wire Input and Output Technology

Unlike standard chargers, this model comes with built-in dual cables that handle both input and output. That means you can charge multiple devices simultaneously — no need to carry extra cords.

Whether you’re powering a phone, tablet, camera, or flashlight, this power bank delivers steady and efficient charging.

High-Capacity Battery for Extended Use

Inside the sleek and compact body lies a Grade A polymer battery with a total capacity of 20000mAh (74Wh). That’s enough to recharge an average smartphone up to five times on a single charge. Perfect for travel, outdoor adventures, or emergency backup, this capacity ensures you never run out of power when it matters most. The internal battery is built with 9960115/37Wh x2 cells, offering reliable performance and long-term durability.

Efficient Solar Power Charging

The integrated solar panel measures 148 × 60.5 × 1.6mm and provides 1.0W output (5V/200mA), allowing you to recharge the device using sunlight. While solar charging is best used as a secondary source, it’s invaluable for outdoor use or power outages. Whether you’re hiking, camping, or working remotely, you’ll always have access to renewable power.

Smart IC Chip: IP5306

At the heart of this solar power bank is the IP5306 intelligent chip, which ensures safe and stable energy management. It automatically detects connected devices and adjusts the power output for maximum efficiency. Built-in protections prevent overcharging, short circuits, and overheating, safeguarding both the power bank and your electronics.

Durable Fireproof Build

Constructed from ABS+PC (VO fireproof) materials, this solar power bank is designed to withstand daily use and harsh environments. The fire-retardant casing not only provides durability but also adds an extra layer of safety — a critical factor for travelers, outdoor enthusiasts, and emergency kits. Its compact size (155 × 75 × 23mm) makes it easy to carry in your bag or pocket, while the 175 × 100 × 32mm package ensures safe shipping and storage.

Lightweight Yet Powerful

Despite its large capacity, the product remains impressively portable. Weighing only 392g (+55g), it’s ideal for both everyday carry and long trips. You can easily store it in your backpack, car, or emergency kit without adding extra bulk.

Fast Charging Performance

The dual-wire configuration supports 5V/2A (Type-C) and 5V/2.1A (USB-A) output, offering faster charging for most modern devices. Thanks to the intelligent IC, your phone or gadget will receive optimized power delivery without overheating. Both wired inputs can recharge the unit efficiently, giving you flexibility based on your available power source — wall charger, laptop, or solar energy.
