    Factors to Consider Before Buying

    1. Capacity: Evaluate your power requirements to determine the capacity you need. Consider the number and type of devices you want to charge, and their battery capacities.
    2. Size and Weight: If portability is a priority, choose a battery bank that is compact and lightweight, making it easier to carry in your bag or pocket.
    3. Input and Output Ports: Check the number and type of ports available on the battery bank. Ensure they are compatible with your devices.
    4. Charging Speed: Look for a battery bank that offers fast charging capabilities to minimize downtime.
