[Q] Galaxy nexus MHL/HDMI

Hello guys,
Lately I have been using the MHL/HDMI cable for gaming on my Galaxy nexus to play Modern combat 3. Since i'v tethered my dual shock controller through bluetooth, Wifi is on for online playing, and the screen is on while playing, always run out of juice!! Even though my phone is plugged to the charger.
so i have been wondering if any of you guys could help me put my screen off while plugged into MHL/HDMI. Or help me under volt. thank you

Are you sure your using the correct charger?
Try a 10watt USB iPad charger.

am using the apple 10W USB Power adapter. input: 100-240v ~0.45A.... 50-60Hz Output: 5.1V 2.1A
the white block one

I think the nexus is limited to 1A. Not sure if the limit is changed when using mhl. Also, heat is a factor. It might be possible to get longer play times if you have air flow all around your nexus to keep it cooler. Meaning elevate it without a cover on. And maybe a fan blowing on it.

When you charge go to phone status in the settings does it say charging Ac or charging usb ? if it says charging usb there's your problem.

MHL is limited to 500ma per spec.

Q. 4
Pogo pin charging seems like our only hope.

Came here to ask the same question as no matter what adapter I used it showed charging USB which for gaming isn't enough by a long shot. Good to know i'm not the only one.
Is there a way to get the kernel to ignore the type of connection and draw as much power as is possible? Similar to how many of the tablet kernels were modded to allow charging over USB and not just the adapter that was packaged with the device.

Has anyone tried a charge only cable? These are the cables which have a short across the data pins. I know it's a long shot since the AC charger should cross the same data pair.
I hope there is some XDA magic that can be applied to draw more current. I have a feeling it will require a hardware tweak of the MHL adapter and driver level hacking of the silicon image chip.

I have tried a few different AC adapters including the blackberry, HTC, and a random LG charger and they all showed as charging as USB and not AC. I would imagine it is in all MHL adapters and/or the phone.

Need a USB car charger for various uses

I'm looking for something like http://www.amazon.com/Monster-129907-iCar-iPod-iPhone/dp/B005ES8SRU/ref=sr_1_10?s=electronics&ie=UTF8&qid=1366079625&sr=1-10&keywords=monster+icar
I have a 2012 Mazda 3i Touring and the center console has a 12v port and 3.5mm audio port. I use bluetooth and the motorola rapid rate charger for my Galaxy Nexus and it's fine, but as a courtesy I want to just have something like that and various USB cables in my center console. Is there something like that that will charge the newer android devices at the full, non USB speed, and also charge iphones and ipads at a good rate? I also want to be able to plug in my bluetooth headphones to keep at a full charge, so general compatibility as well.
Any ideas? I've been reading around and it seems like people get the griffin one and solder two parts to get one port the full 2.1a for high powered android devices/ipads and the other port at 1.0 for iphones ipods and other devices, dunno how ok that is to do though. I've also read about some of these blowing fuses in the cars, and I'd like to avoid that.

Will a Nexus 7 (2012) charger work with the Kindle Fire?

Hey, I have a kindle fire (1st gen) and would like to know if the Nexus 7(2012) charger would work. Thanks

Yeah, that will work fine.

Sure. I use a blackberry USB connected to an apple iphone power brick when my kindle charger is not available.
You just need to check whether the output is 5 volts.
Good Luck

Yeah it would, why would not?

Oh, I just thought that it would blow up the device or something, this is the first time I had usb chargers

What about just the kindle? would it work for it too ?

If it has the standard micro-usb then yes. It'll work for anything with the standard micro-usb port.

As said above, it should work fine. I use an HTC cable and charger and they work fine.

Easy, yes it will work.
If the Kindle Fire has a MicroUSB-charging-input, then yes, it will work with all newer than 2009~2010 Samsung Omnia, Galaxy, Wave and Star* chargers and Sony and the last newest Sony Ericssons and HTC etc. ALL HAVE MicroUsb! [The Nokia E71 (2008) has got MicroUSB but not for charging but for Data Transfer, for full file system access and many other advantages choose Mass Storage if available, not MTP!].
ALL Nexus devices even have a MicroUSB!
*Samsung Star is for Loosers, Sttar 2 > Star 3 becausee of CamFlash, CamBTN, ScrRes, WideScr, and 27 other reasons.

MicroUSB is universal now, MiniUSB and the Circle Nokia and the old Sony Ericsson Inputs are too old now, to charge an old Nokia in order you need an adapter, that goes from the MicroUSB to the Nokia. But all new Android and Windows Phone Phones+Tablets use MicroUSB.
But i recommend a real charger for using to charge a MicroUSB-device.
A Real charger is one, that directly goes from the socket to the Device(ending=MicroUSB).
The Nexus charger is a USB-Charger (there is the lettering „ASUS" engraved into it.
You Connect a Cable (USB to MicroUSB) to the USB-Charger and
And such a charger is much weaker than the direct charger.
Best Charger: Hama MO·38E with Trickle Charging

That's not correct. I actually recommend the chargers with a detachable USB cable so you can replace the cable by itself if needed. What is correct, however, is that many USB chargers are designed around the Apple standard and may not work properly with devices that expect the DCP standard.

Advantages of both týpes of chargers:

Well... yes, that could be. This is the big advantage of such a charger. It's good to have both týpes at home but the direct charger is much stronger (faster charge, more power) and this „Hama MO·38E" has even an Optimized Trickle Charging but however...
Both types have theyr adv/disadvantages. For example: such a USB-detachable charger is more practic and flexible but it's much weaker and it's lifetime is lower, if you misuse it. (Bad usage that can cause physical damage to it)
If you use it responsibly, then there will not be any lifetime problems!
That what you say is about flexibility. I wish that there would be one charger with all advantages: Power and Trickle charging of the Mo-38e and detachable cable.
The detachable feature is a big advantages but such a charger is weaker.
Even charging on the PC/Smart-TV is not as fast as the real charger. But somewhere in XDA (adding link later, if/whenever i'm able to find it) i saw something that could measure the charging power and there was an adapter that could bring full charger power from the PC (prooven with this PowerMeasure-Device.) which means that you can almost get the charging power of the Mo-38e off the PC to a device!

Hi, mine says that the charger is too weak, and it can charge slowly

Two port wall charger?

I'm basically looking for something like this:
http://www.amazon.com/Anker®-Dual-P...0&sr=1-1&keywords=anker+two+port+wall+charger
but where both ports will charge Android devices properly. Everything I have found is either a) 1 Android 1 iPhone, like this, b) two iPhone or c) more of a desktop charger and too bulky to fit in a single outlet.
Does anyone have a recommendation for a two-port charger that fits in a single outlet that would charge two Nexus 5s or a Nexus 5 and a Nexus 7 at full speed?

When I search for dual port usb charger on Amazon, there are a lot of results that match your criterias.
Besides this specialized for iPhone or Android is marketing bullcrap.

It's not, at all. iPhones expect there to be a voltage across the data pins to determine the maximum power provided by the charger while Android phones expect the data pins to be shorted. If you use an Android phone on an iPhone charger you end up only charging at USB charging speed (500mA) rather than AC speed (up to 1500mA).

I bought one on Motorolas website, its like $30, comes with a USB Cable, all OEM made for android devices. I know what you mean about it saying one iphone and one android. This one is OEM so you will be OK.

Hm, that looks nice but I'm concerned about the power output. It lists it as a 6W/1.2A charger which would not even be able to charge the Nexus 5 alone at full speed (1.5A) let alone the two together. I would assume that if you have two devices connected you would get 0.6A each?

I just got this one because (finally) it is a charger that doesn't use up multiple sockets in a power strip. The whole charger is the size of the plug:

If you think the apple port won't work well with android devices, you could get one of these gadgets:

sick of chargers all over house?

i have 4 devices so this unit was perfect for my needs or anybody sick of having usb cables all over the house. shipping was on time and unit was secure and safe and inside the box is a INATECK 4 Port Wall Charger and user manual and the manual was simple to read and unit easy to use regardless but nice to have incase its needed. the unit is sturdy, with a good weight to it which i liked as i just plugged unit in wall and now im ready to charge all my devices at once. unit also has a blue LED thats bright but i like that fact because i charge mostly at night and its easy to see without turning on the light. i tested the unit with a Iphone 5/GS4/GS5 and a ipad and no issues there using your devices usb. 2x 5V/2.4A (Super Charger) Interfaces: Supports 5V USB charged devices on sale (Most types of mobile phones,tablet PCs or digital devices);2x 5V/1A (Universal) Interfaces: Supports smart phones from iPhone, Samsung & other 1A USB devices are the spcs for the unit and those pretty much cover anybody looking to make charging your devices easy.
and for under $15 its a must for families or person with multiple devices. i have used other usb wall chargers but a key selling point to this unit is the built in surge protector which is also CE&FCC certified and in my opinion with the costs of our devices that is a great feature and also unit is premium high power enabled to allow full speed charging. really liked the product overall and the price is lowest i have seen plus all its features make it a must.
