Understanding Power Banks

Before diving into my recommendations, it’s essential to understand what a power bank is and how it functions. A power bank is a portable battery that allows me to charge my devices on the go. The 4000mAh capacity strikes a balance for me, providing enough power to recharge my smartphone without being overly bulky.
