Designed for outdoor use, the powerbank can be hung from a backpack or placed in a sunny spot to harvest solar energy and provide portable power when mains charging is unavailable. The housing uses water- and shock-resistant materials to withstand typical outdoor conditions.

Advantages

The integrated five-panel solar array offers convenient on-the-go recharging when access to mains power is limited. A 27,000 mAh capacity stores significant energy for multiple charges of smartphones, tablets, and other USB-powered devices. The foldable design and attachment points make it easy to carry on a rucksack. Water- and shock-resistant construction increases reliability during outdoor activities.

Key specifications

• Battery capacity: 27,000 mAh
• Solar panels: 5-panel foldable array
• Material properties: water-resistant, shock-resistant housing

How to use

Unfold the solar panels and position them in direct sunlight for best charging performance; angle and orientation toward the sun will affect charging speed. Use the powerbank's USB output ports to charge phones, tablets, or other devices; recharge the internal battery from mains when available for faster replenishment. Secure the unit to a rucksack or place it on a stable surface while charging to prevent movement and ensure exposure to sunlight.

Recommendations

For optimal results, keep solar panels clean and unobstructed. When not in use or during heavy rain, store the powerbank in a dry place. Recharge from mains power before long trips to ensure the internal battery starts fully charged, and avoid prolonged exposure to extreme temperatures.
