Engineered for iPhone 11 Pro Max, the Smart Battery Case gives you even longer battery life while offering great protection. Inside, a soft microfibre lining helps protect your iPhone. And on the outside, the silky, soft-touch finish of the silicone exterior feels great in your hand. A soft elastomer hinge design makes it easy to put the case on and take it off. The case features a dedicated camera button that launches the Camera app whether the iPhone is locked or unlocked. A quick press of the button takes a photo and a longer press captures QuickTake video. It works for selfies too. The Smart Battery Case is also compatible with Qi-certified chargers. You can charge your iPhone and battery case simultaneously. The case can be charged even faster with USB-PD–compatible chargers. Case material silicone. Compatible with Apple iPhone 11 Pro Max. Manufacturer’s 1 year guarantee.
