Buying Guide

Match capacity to your usage

Choose a case capacity (mAh) that fits your charging needs—higher capacities like 8500mAh offer multiple full charges, while smaller packs prioritize slimness

Check compatibility with your model

Confirm the case is designed for your phone generation (e.g., iPhone 16, 17, or Pro Max) to ensure proper fit, port alignment, and charging performance

Look for protective construction

Consider cases with reinforced or EVA-style protection if you want storage and impact resistance in addition to battery backup

Evaluate charging features

Compare wired vs wireless support, pass-through charging, and output power (e.g., 15W) to match your charging habits and accessories

Balance size, weight, and design

Slim designs sacrifice battery capacity for wearability, while bulkier cases accept higher mAh and added protection—choose based on daily carry preferences
