Running out of battery on your cell phone has become one of the main annoyances in modern users’ daily lives, whether during work hours, on an extended trip or in the middle of an event. To end this dependence on sockets, the power bank is no longer an optional item and has a permanent place in the backpack or purse of those who need constant autonomy. With the variety of options available, however, defining the appropriate model requires attention to factors such as capacity, recharge speed, compatibility, size and weight.
Therefore, TechTudo has put together, in the list below, seven portable chargers that stand out at the moment, each with specific characteristics. The selection ranges from affordable alternatives, such as the Basike B-078E (from R$75), which meets basic needs, to more advanced alternatives, such as the Anker A1664 (from R$422), praised for its durable construction and premium features.
Portable chargers represent a practical solution for those who spend a lot of time outside the home with their cell phone in heavy use. Several criteria influence the choice, and the list considers real user reviews from large retailers.
