I used Afton's wonderful instructions to add a second battery to make my sled native 24v, and I've powered several 24v cameras just fine, but I'm a little concerned about the 85w Alexa.
Still, the Master has a 15amp breaker. An Alexa at 24v draws roughly 3.5 amps, add another 4 amps for AKS and I should be well within the limits... I've never had a bad experience with my Master wiring, I just want to be triple sure that I don't blow anything up!
Whenever I've used the Alexa in the past, I just run an onboard battery, but I would like to shave a little weight.
