Mophie's new Juice Pack case works around the lack of wireless charging on the Google Pixel XL. The new case adds an extra 2950mAh battery to your smartphone on top of the Qi wireless charging capability. Mophie says this protective case adds up to 50 additional talk time for the Pixel XL. And if you charge wirelessly, it can charge both the phone and the battery pack. And if you don't have a Qi wireless charging pad, Mophie claims it works with "other wireless systems."  

If you want faster charging times, you can still plug in the USB Type-C cable and it'll charge the Pixel XL first before the Juice Pack. Perhaps the biggest disadvantage of the Juice Pack is that it adds on 3.8 ounces to an already gigantic device. But if you've been looking for a wireless charging option, the Mophie Juice Pack goes for around US$100.
