To charge your Flow, connect the USB-C cable provided to the port on the back of your charging dock. Then you can plug the other end into an available USB charger or USB port on your computer.
Finally, place the Flow on its charging dock as in the image below. In most cases, you'll see the charging light on the base of the device light up. However, if Flow is already at 100% battery, this light won't illuminate.
Note: You can also charge your Flow directly using the USB-C cable via the port underneath the device.
