Why is nook's charger so special?
I cannot use a regular micro USB cable or the original nook color cable with a with a 2.0 or 2.1 mA USB charger (e.g. iPad or other OEM high mA chargers). The stock firmware (tried with 1.01, 1.1 and 1.2) says not charging. Even regular usb cable to the computer doesn't charge the device. The only combo is original nook color cable with the original nook color charger (apparently 1.9 mA).
However when I boot into CM7 through my microsd card, I can use any combo of usb cable and charger to charge the device.
Is there a software block that only lets the original cable with the original charger? If so, is there a way to circumvent this without having to boot into CM7? I just hate to carry around another set of usb charger and usb cable in addition to the one that I have.
have you gotten it to boot yet on the stock rom with a non-nook micro-b usb cable? I am wondering if it's possible

Just got my A500. It has a lot of cool ports, including the proprietary charging plug. On other devices it is possible to use the micro USB cable to connect to the PC and to charge the device via a wall charger.
So my question is this. Can I use a micro-usb charger to charge my A500 via the micro-usb slot?
Not on the A500. Takes too much juice to charge the big batteries. You have to charge through the plug .

Has anybody tried this: 1. Setup a powered USB hub plugged into the Micro OTG cable 2. hack the cable from right after the OTG cable to where it plugs into the hub, so that the voltage pins are exposed 3. solder in the voltage pins to a usb connector so you can plug in a normal charger [5V 2A] 4. check to see if you can use the USB hub and charge at the same time
I currently have a Asus transformer TF101 and the primary use is watching clips off a 500GB usb HDD. I really, really want to get a N7 and sell my TF101, but if charging & simultaneous host mode is not possible, I would be slightly hesitant to buy it, because I would be eating up the battery much faster than I would like.
Hi,
I bought PowerGen 3.1A Wall Charger, when I use with original Micro USB cable that come with my Samsung Galaxy S4, the charging current is 1.9A, when I use with a generic USB cable, the charging current is only 700mA. (I have a way to test the charging current)
Does anyone know which Micro USB cable that carry fast current, such as 1.9A like original USB Cable that come with S4, or even better, carry up to 3.1A that this Wall charger provides?
Thanks All.

Faster charging is enabled in the kernel, not by a cable bro.
Hi,
you have to look for custom kernel with fast charging support. I am using faux123 with fauxclock app.

Something bout the stock USB to microusb cable for the g2 is special....I need another cable for car charging purposes. POINT ME IN THE RIGHT DIRECTION PLZ!!
My dual usb car charger discharges 2.4amps. I tried all my usb to microusb and i can only output 900mA and (slow charge mode popsup
I use the stock usb to microusb cable and WAM.....charges at 1850mA
I suspect I know the answer to this, but I just wanted to get confirmation.
I was originally led to believe that the Galaxy S5's included USB 3.0 charging cable allows faster charging than a USB 2.0 cable. Upon thinking it over, the 3.0 cable should really only provide faster charging compared to USB 2.0, and only when plugged into a USB 3.0 computer port.
When using the same USB 3.0 cable via an AC wall adapter, the power output of the wall adapter should be the only thing that really determines the charging speed: Fast charging with a 2-amp wall adapter, slower charging with a 1-amp adapter; whether the cable is USB 2.0 or 3.0 should not matter.
Am I correct here?
The USB 3 cable provides only extra data lanes no extra charging speed. The AC charger will charge at 2amp and on PC you are likely to get not much better than 450mili Amp.
