The recent release of Qi-compatible iPhones means that wireless charging pads will be popular stocking stuffers this holiday season, and you can get Anker’s 5W model for $19 right now, down from its usual $24. That’s only half as fast as their 10W model (currently $26), but it’s worth noting that iPhones max out at 7.5W wirelessly, and it’ll still be plenty fast for overnight device charging.
