PowerWave 7.5 Stand An expanded charging surface, adaptive technology, and advanced safety systems combine to create PowerWave, the premiere wireless charger from Anker. Advanced technology detects your wireless charge-compatible devices, delivering up to 7.5W for Apple devices, and 10W for Samsung. A state-of-the-art internal cooling fan prevents overheating and slowdown, maintaining high-speed charging from 0% to full. Ride the Wave The wireless evolution of Anker's world-famous technology uses a high-efficiency chipset and an internal cooling fan (the first of its kind) to provide the fastest possible wireless charge in its class. One Charger to Power Them All Power any wirelessly-charged device in your arsenal at an uninterrupted 5W. Charging power is boosted to 7.5W for iPhone (as fast as Apple's proprietary wall charger), while flagship Samsung phones get a 10W extra-fast charge. Versatile Viewing Twin charging coils let you watch videos in landscape orientation, or stand in portrait mode for web browsing and Face ID—all while keeping the power flowing. Just in Case Don't worry about taking your case off whenever you have to charge. PowerWave delivers charging power directly through cases up to 5 mm thick—including Otterboxes.
