Don't worry if your iPhone 8 / 7 Plus somehow falls out of your grip. This case is constructed from a resilient and durable material, ensuring all-round protection for your device's back and sides.

Protective IC technology efficiently prevents short-circuiting or overcharging

You'll never need to worry about leaving your phone in this case, or even forgetting to take the case off charge. A built-in protective IC circuit efficiently and effectively defends your device against potential short-circuiting or overcharging, so both your iPhone and the case will never take more power than they absolutely need to.

You don't want to remove your phone every time you need to charge this case. That's why the case features pass-through power delivery, meaning while you charge the case you can leave your phone inside - still enjoying all the protective and battery-prolonging benefits you would normally enjoy. The protective IC technology built in to the case delivers only the power each device needs, too, so there's no fear of overcharging or damage to your device at all.
