Apple's ?MagSafe? Duo is meant to charge an ?iPhone? and an Apple Watch, but it does not work well with the oversized Apple Watch Ultra. In fact, Apple published a support document instructing people on how to best adjust the ?Apple Watch Ultra? to charge with the device. In some cases, the band needs to be removed before the Ultra and the Duo can work together, and the ?Apple Watch Ultra? is not listed as a supported device on the ?MagSafe? Duo page on Apple's website.

There is no clear method for updating the ???MagSafe??? Duo's firmware, but it needs to be plugged in and connected to an Apple device for a firmware update to initiate. You can check your ???MagSafe??? Duo firmware by following the instructions in our MagSafe how to.
