Dying to know the capacity of the Apple Vision Pro battery. In MKBHD's video he lists 3166 mAh on the back. I'm really curious what the Volts are, because if it's ~4V like the iPad that would be very small (12 Wh) so I doubt it
For reference the 12.9” iPad has a ~ 10000 mAh battery at 4V for a total of 40 Wh, so if the Vision Pro battery is around that, that would put it at 12V or so. That would be awesome because you could then triple your battery life with a normal 100 Wh external battery
@christianselig thinking of using an anker high capacity battery with it on the go.
@christianselig I was surprised that MKBHD as a tech reviewer doesn't seem to know how battery capacity works.
@christianselig lithium polymer cells are all 3.7v and the Vision Pro shouldn't really draw that much more than an iPhone at load, so a battery capacity in that range seems not unreasonable.
@fencepost Individual packs, sure, but they’re often wired in series. The MacBook's lithium pack is around 12V, for instance
@christianselig @Migueldeicaza I just need UPS to show up and then all the magic is revealed…
@djb_rh I’ll be right over
@siracusa Ah that’s pretty good! Will be easy to add a bunch of extra hours by daisy chaining the same kinda external battery you’d use for a MacBook
@christianselig @siracusa OR you could find an adapter for the "fat" plug->USB-C that goes into the battery. Did you see that article yesterday about the wire going into the battery pack being removable with a SIM tool? Someone is gonna reverse-engineer THAT sucker!
@christianselig @siracusa yeah you only need to hot swap your extra battery if you’re on a long flight. The main battery is the backup.
@siracusa @christianselig Smells like 12 V to me.
@andy @siracusa @christianselig weirdly… 13v.
PD allows 12v or 15v as standard but they went with 13.
@SamTheGeek @andy @siracusa @christianselig PD chargers can output variable voltage for devices that support it. It's called PPS (Programmable Power Supply)
This charger of mine, has a few fixed voltages, but also supports variable voltages, between 3.3 and 21 V at 3.09 A
@iboalali @andy @siracusa @christianselig yeah but when you build something that *requires* PPS, you end up with a bunch of PD chargers not working with your hardware.
@SamTheGeek @andy @siracusa @christianselig why does it need to be required? My phone supports PPS chargers and normal PD chargers without an issue
@iboalali @andy @siracusa @christianselig the headset takes an input of 13v! It’s just weird to me that they’d have designed it for 13v when all the hardware you can easily buy is designed for 12v or 15v. (The battery will of course negotiate a variety of PD speeds)
Not sure if people have mentioned AVP 2 hr battery life as an intention to get people from wearing it too long, forcing a break, but I’m certain some have thought it.
@siracusa @christianselig 13V. Weird.
@snazzyq @siracusa @christianselig might just be four cells in series.
@snazzyq @siracusa @christianselig 35.9Wh / 3.166Ah = 11.34V
@christianselig Thinking logically - Vision Pro probably consumes more power than MacBook Air. That seems logical: "bigger" screen, an R1 coprocessor with unknown TDP, full M2 and entirety of a computer.
So I would guess that battery would have more or less parameters of a laptop battery at 11-12V
