The iPhone 17 Pro Max is a powerhouse of innovation, offering advanced features, stunning performance, and all-day usability. Yet, for heavy users who rely on their phones for productivity, entertainment, and photography, the battery can drain quickly under demanding tasks. That’s where battery cases come into play. A high-quality battery case not only extends your phone’s usage but also protects it from everyday drops and scratches. For iPhone 17 Pro Max users, some of the best battery cases include the Panduk battery case, Alpatronix battery case, and Gix Foxi case. Each of these cases is designed to deliver extended battery life while maintaining sleek and functional protection.
1. Panduk Battery Case

The case supports fast charging with up to 20W output for the iPhone and 18W input for recharging the case itself. Pass-through charging lets both your phone and the case charge simultaneously, optimizing efficiency, safety, and reducing downtime. An integrated LED screen displays the remaining battery percentage in real time, while simple controls—press once to start charging or double-press to turn it off—help prevent energy waste and provide full charging flexibility.
