Um... The incredible has a micro-usb port. You can't shove a mini in there.

And the answer is yes and NO. The charge voltage is always the same but different phones use different methods to get signaled for charging. For instance the iphone uses 2.7V across pins 2,3 to signal and 5V across 1,4 as I recall.
You won't do damage using the wrong one though. It just won't work and you'll scratch your head.

His question still asked if he could use a mini usb charger for this phone, and no, he cant. The incred uses a micro-usb port, where a mini will just not fit.

Umm, no he asked "Does anyone know if all mini usb car chargers are the same voltage? Can i use any mini usb cig charger i have?" and larsdennert's answer was a direct answer to that exact question.

so this thing is a micro usb like the blackberry? gonna buy a big pack of usb cables for it and I don't wanna buy the wrong ones.

the cable you should buy would then be USB A to micro B. Monoprice is sold out- I ended up buying from Amazon, but the shipping was a bit ridiculous

I just ended up getting a charger from wal-mart that was labeled for a Motorola, but it works fine since it is a micro USB

I have alot of motorola mini usb chargers... I bought a micro usb adapter for 6 bucks from radio shack... it charges and works as far as I can tell... only thing I notice is that the motorola is 5v-550mA not 5v-1A ... I dontk know if this will have any long term effect on the batteries... I think it just makes it charge slower

I don't know the difference between micro and mini, but I hope I can use the car charger I recently purchased for my Touch Pro for my new D.I.

I tried using the BB brand car charger and I got a message on my Dinc that I this manufacture was not compatible with the Dinc. WTF?

I've had no problems using any car charger that allows either changing tips (igo) or has a USB port so you plug the correct cable in. I even have an Apple car charger that works as long as I use the correct USB cable.
But now a slightly different question....
I notice the Incredible WALL charger says 5v at 1A, and my WALL chargers for Apple are 5v .5 A, so I assume the Apple charger works for Incredible, only slower charge, but is it same to use the Incredible Charger for the Incredible? I hate traveling with a zillion chargers.

Technical hdmi dock question

Ok lets try and see if I can explain what I mean... im interested in the new smartdock (it has hdmi 3 full size usb ports and charging jack) looks great but its not released here in the uk and its gonna be expensive.
Now I have a generic ebay dock on its way with charge and sync capabilities it has 2 micro usb ports i was wondering if it would be possible to plug a mhl hdmi adapter into one of the micro usb ports of the dock and use the dock for my tv out needs sounds simple enough but...
This is where I get a bit confused I hear the galaxy note 2 supports a new 11pin micro usb mhl hdmi adapter and the old 5 pin hdmi adapter used on the note 1 and s2 wont work. So I suppose the note 2 micro usb socket is 11pin the new mhl hdmi adapter required is 11pin... does anyone know if standard usb architecture on generic docks would support 11pin or 5 pin mhl hdmi as if the docks architecture is only 5 pin it obviously wont work as it would be going from 11pin (phone) through 5pin (the dock) to 11pin (the mhl hdmi). I hope someone understands what I mean.
Or maybe someone could explain to me the differences between 5pin and 11pin and maybe I can work it out myself.
Im totally confused as I thought all usbs were the same apart from speed and that was the beauty of usb its universal serial bus.

The s3 and note 2 can ouput multi-chanell audio through hdmi. I guess that's why . So far as I know none of the docks supports that configuration....dock...usb...mhl. The smartdock is the only one . I'll go that way...

The SGN2 micro USB port has may features:
Charging (up to 2A)
OTG Host mode
MHL video/audio
USB Audio stereo output
Docking Profile
If you dig deep into the USB spec. you will find how these seperate features all come together by use of the micro USB - ID Sense pin 5.
My guess is if you attach a SGN2 > generic dock > w/ USB (x2) > HDMI cable > HDMI display <<<< this cannot work as the USB ports have no way to convey the ID Sense pin to the micro USB port of the SGN2.
I'm waiting on stock for the smart dock. I wish it had a method to pivot landscape though.

App - Ultimate Rotation Control can sort that (using it with the Smart Dock I have presently). Tasker should also be up to the task of sorting rotation issues with the Smart Dock.

Ah so you think it wont work through the generic dock this is shame as it would be a money saver and I have one on the way. I hoped the dock port might just work as an extension of the micro usb port on the phone meaning the mhl hdmi would work as usual but I had my doubts.
I have got an app called orientation control from the play store it was 96p and is very handy and easy to force landscape it even forces lanscape on the stock homescreen great for docking.

NEXUS 7 Car install Diagram

Hi All,
If this has been done before please ignore.
I have been doing a fair bit of research on the NEXUS 7 as a car head deck but no diagram to go off.
Can you please advise if the Diagram below is accurate or if i need to amend certain areas to make it work. The NEXUS 7 will be slide in slide out.

Subscribed to see what others have to say. I am hoping to skip the head unit and sub and go right from the N7 to the amp. My worry is getting clean audio out of the N7 while it gets power.
I have a ground issue somewhere currently where if I am charging a device and have it plugged into the aux port of my head unit, I get tons of static and noise.

Only comment I'd make is that if you're going to use the POGO pins to power it why not grab the audio from there also? Seems safer to use a non intrusive (without a plug going into the Nexus) method over sticking in the headphone jack.

He probably didn't know he can do that. You can also use a USB dac and get audio that way. Probably much cleaner and it will also fix his ground loop issues.
I owned a Galaxy Tab before the N7 and it was MUCH WORSE at adding noise to the headphone output. The N7 is much much better at isolating that ground.

Correct i didn't even know what those 2 pins were for Audio or if they were for D+ & D- so thanks I have adjusted the picture accordingly. If you could check that out that would be great. After i get everything from Evil Bay this week i will do lots of pictures and full write up.
Thanks So excited to get started.

so are you saying that the POGO pins are THAT simple? and here i was building a dock for my N7!
if this is true, you rock man!

Unless your drawing is just an example, your speaker wiring needs to be changed so you're not daisy chaining the signal. Run 'home runs' to each driver.

Also there's no need as in actually you can't do that have a DAC on the audio lines. They are analog L+ and R+ with the ground being common between power-, L- and R-. Look for the POGO thread over in the accessories subforum along with one on a homemade dock for more info. There is no USB on the POGO pins.

Close, but not there yet. The 2 middle POGO pins are Audio +/-, and won't connect to a DAC as it's already an analog output. You can connect the DAC via USB though, and get the highest quality audio possible out of the N7.
HOWEVER: if you want to charge AND use OTG (DAC and external storage will connect via OTG), then you'll need a kernel which will support that. Running power through the POGO pins also requires a special kernel. This is the only one I know of:
http://rootzwiki.com/topic/37755-timurs-kernel-usb-host-power-management-usb-audio/
The fixed installation is the best choice for car applications.
Alternatively you can use audio out and charge through the POGO, and use a kernel like faux123's kernel to charge and have USB OTG (but won't work with a USB DAC), though there are limitations to this setup.
EDIT: I've attached a diagram of my current car setup.

Thank you for your diagram you've definately got alot going on in your car Looks good.
This is what i have bought.
Nexus 7
FiiO E10 USB DAC
Clarion EQ746
3ft male to female USB connection
3.1A Dual USB Charger
Micro USB female
AUX to RCA ( Not sure what ill be using this for now )
Pogo Pins
Magnets ( Not sure if I'll use these yet )
Will the above work? I've read way to many forums on this subject and no one is actually clear.
If i cut up and strip back the rubber around a Male USB can i use this as my POGO pins connector to the USB DAC + Kernel suggested?
*phillip1953* It is just a quick drawing and i can assure you this won't happen when installing.
Everyones input is greatly appreciated Thank you.

I think I have a working diagram to go off. On a positive note my NEXUS 7 arrived today Wohoo.
Also when i get free time i will also create a Nexus 7 dock with built in speakers using the OEM POGO pins?

You really need to read the whole thread that MetalMan posted above. It will show you what you're doing wrong, and give you more to think about.
EDIT:
I really wouldn't charge off the pogo pins if I were you. Get a USB OTG + Charging Y Cable and just plug/unplug that as needed.

Wireless Charging plus USB OTG?

Can't find much information for the Xperia Z for what I am looking for, so might as well ask.
USB OTG, from what I can gather, will only allow us to play media on a USB stick, but not charge at the same time.
What about using a QI Wireless charging kit which connects via the two exposed metal plates on the side by the USB port? If we use this method, can we still use USB OTG functionality at the same time as charging?
If so, brilliant, I can then figure out a method of integrating a QI charging kit into my current phone case for this phone

I had to try to connect the charger to my phone using a standard female USB-A to USB-C adapter and it worked perfectly.
So to answer your question, "There is, sort of, just buy the adapter you need and use that [emoji846]"

Looking for something I can use with longer existing cable. Don't understand why they supplied charger with attached cable. My S3 Frontier charger has socket.

I think that I read somewhere that the reason there is no plug supplied with the charger is that "most people have lots of chargers already". But also I guess it is a way for us to hand over even more money.
I have not tested this fully but I bought a new, third party, charging cradle for my Gear S2 watch and I would guess that stand should be able to charge the watch 3 also as it is a bit bigger than the original Gear S2 cradle.
Tho I have not really looked into the specs either the S2 cradle or the Watch 3 charge pad.
