Buying Guide

Match capacity to your needs

Choose higher mAh for multi-day use—cases here range from mid (4500mAh) to high (8500mAh) capacity to suit light to heavy users

Check device compatibility

Confirm the case supports your phone model (iPhone 11, 16 Plus, 17, 17 Pro Max) to ensure proper fit, ports, and button alignment

Prioritize charging features

Compare wired and wireless charging support and output (for example 15W fast-charge on some models) to match your charging speed expectations

Consider protection and design

Look at protective elements such as EVA storage cases or rugged shells versus slim designs, depending on how much bulk and protection you need

Evaluate additional compatibility

Note extras like CarPlay support or dedicated storage cases if you need integration with vehicle systems or organized charger storage
