Charging multiple devices at once while on the go just got easier. The Chi-Charge Stack is our brand-new compact device that can wirelessly charge a compatible phone, watch, and earbud case all at the same time. It is a powerful device that makes a powerful statement. Please note: comes with a Type-C to Type-C charging cable, though users will need to plug into a Type-C wall plug adapter with at least 20W output to operate the device. The wall plug adapter is not included. NYSE logo.
