That being said, it appears that Huawei isn't done quite yet. Enter the "ST310-S1" - an interesting external backup hard drive solution, specifically designed to work with the new Mate 20 series. The round (136mm x 29mm, 270 gram), fabric-coated device looks like a wireless charger on the surface, but it actually houses a 1TB hard drive (other tiers might also be available) designed to automatically or manually backup data off your phone. It also doubles as a pass-through charger. You can connect a 5V2A, 9V2A Huawei fast charge or a 5V4.5A Huawei super fast charge adapter to it and have the juice pass to the handset, as well. Unfortunately, the new 40W SuperCharge standard seems to be notably absent from the list.
