The size and capacity of a portable power bank depend on your usage requirements.

For everyday use, opt for a small and portable power bank.

Devices in Use:

Consider the power requirements of the devices you intend to charge. Different devices have varying power consumption, so choose a power bank with sufficient capacity to meet the needs of all connected devices.
