Follow general battery safety: avoid exposure to extreme temperatures and do not disassemble the unit.

What to consider before purchase

• Ensure your device is compatible with standard USB output charging and check required current for optimal charging speed
• Consider physical size and weight relative to your portability needs for travel or daily carry

• Plan for appropriate charging cables or adapters if your device uses a non-standard connector

Usage recommendations

For best performance, charge the power bank fully before travel, use original or high-quality charging cables, and keep the unit in a well-ventilated area while charging. Store the power bank partially charged if not used for extended periods and avoid exposing it to heat or moisture.
