- Port Types and Quantity: Consider the types of ports (USB-A, USB-C) and the number of ports available to ensure compatibility with your devices and the ability to charge multiple devices simultaneously.
- Size and Portability: Power banks come in various sizes and weights. Smaller, lighter models are more portable, while larger ones often offer higher capacity.
