Xbox Wireless Controller - Aux Voltage Output

The dock takes the input current and passes it on to the controller, put simply, it just adds an extra step into the charging process, saving you from plugging in/unplugging a cable to your controller. Electrically the same principles apply, you'll
need to match the voltages!

If you don't mind me asking, how do you know that the dock simply passes the current and voltage as is to the controller without? I would think that it brings down the voltage and current to the output voltage and current printed on the back of the dock
which is 5V and 0.55A.

Why would they print out said voltage and current on the back if all it does it pass the voltage/current through?

Also if you notice, the current printed on the dock is 0.55A compared to the current printed on the controller which is 0.48A. I think that confirms that the amperage on the back of the dock is not a reference to the controller's amperage but it really does
specify the amperage that the dock outputs.

Where are you ordering yours? And does anyone know the exact input and output voltage for a US xbox?

Thanks Sn1p3r, that makes sense. I bring it up because of the recommendation by support not to use regular rechargeable aa batteries but regular alkaline aa batteries are ok. One of the differences I noticed was the voltage as you mentioned (1.2v for rechargeable
and 1.5v for alkaline). I'm curious if the lower voltage from the rechargeable aa's is contributing to many peoples controllers disconnecting, including my own.

I also wanted to compare the voltage of the play and charge kit to regular aa's and rechargeable aa's. Energizer also has a licsensed charging stand/kit with a battery pack to compare.

Why are regular rechargeable aa's not recommended but these other rechargeable options are? Of course for the play and charge kit it's just so Microsoft can make their money instead of a third party - or is there a technical aspect to it?

Hi buddy,

As with most things like this nowadays, I'm pretty sure the controller will have it's own converter inside that'll convert whatever input voltage it gets it will optimise itself. I remember building such a thing when I was studying electronics that no matter
what voltage you put in it would give a constant voltage out. So long as you stick within a certain range. I remember having to maintain a perfect 5V in order for the particular oscillator I was using oscillated at exactly 1 Hz. The problem was, the 5V DC
transformer I was using gave anywhere between 4.5 and 5.5V So I built this little thing out of capacitors and diodes that would give a steady 5V all the time. Can't precisely remember what they called that particular little circuit though or precisely how
it worked. I just remember that there is such a thing, it's cheap as chips, and not that difficult to manufacture. So I'd be very surprised if the Xbox Controller doesn't have something similar in it.

I use rechargeable AA's which are 1.2V each and the standard disposable 1.5V AA's work equally as well. I'm pretty sure the controller will have it's own regulator that will probably step the voltage to various amounts for all the different components within
the controller so as long as you're between those two (2.4-3V) I'm sure you'll be ok.

I am curious though as to why you are asking...

Hi,

as far as I know this is possible.

The output voltage from the PSU to the xbox is the same.

Only the input voltage is different.

Just make sure you don't simply connect you're own psu to an travel adapter !
