Thinkgeek recently reviewed a replacement wall plug that can supply up to 2.1 amps over a USB port.
Seems like a perfect fit for where you charge your nook color!

In a similar vein, ThinkGeek also has this, which lets you draw USB power from an outlet that has something else plugged into it. Up to 1 amp.

I'm wary of the 1 amp output, though that looks useful for when you're on the go or travelling.
The 2.1 amp permenant household solution means I can create a charging dock in my office with very little fuss.

I got one of these for my birthday this January. Really works but I still think the NC charges faster directly from their dedicated wall plug.
Yes, I'm not sure why but some people get 2 amp usb chargers that charge their nook at the same time as the stock charger.
However, my experience has been not the case.
The cable itself is known to be important, but the charger also has something about it that's unique or made differently to allow full 2 amp charging.
There are usb inter-connects that people sell that allow charging from lower amp chargers, I'm wondering if this bypasses whatever check that keeps the nook from charging at 2amps on a nonstock charger.

Ok, so hoepfully someone can clear this up as I don't yet have my Kaiser (tilt) and am trying to get some accessories.
I previously had a PPC-6700 which synced and charged via a standard mini-USB jack.
I then upgraded to the PPC-6800 which I only had for about a week (had to give it back to my work). With that device there was a different type of usb jack on it that seems to be what the Kaiser also has. Can someone tell me what this is called?
From my recollection however, this slightly different jack would also accept the typical mini-usb plug as i can remember using my PPC-6700 wall charger on it.
So can you use standard USB to mini-USB plugs to interface the Kaiser with either a PC for sync/charge or to a wall-charger? What is the new interface called and what is the point of it?
thanks much!
I may have actually answerd my own question as I have found (I think) the name for this new interface... EXTUSBTM ? Is this correct. And the point is to interface the charger/sync and audio headset together?
If this is all it does then I should be fine using all my old mini-usb plugs for data interface/charging, right?
thx!
Yes, you can use a standard 5 pin mini USB cable. The port is HTC's 11 pin combination sync/charge/audio port. Both their plug and the standard 5 pin mini USB plugs fit and work.
Wikipedia (for once!) isn't too big on details here: http://en.wikipedia.org/wiki/HTC_ExtUSB
But basically, it's got 11 pins to handle audio, power and syncing.
Have a look here for pinouts etc.

AT$T Cheaped me out again. I only got a standard USB sync cable from them! DoH! lol
Hi,
So I've built myself a solar powered battery pack for my awesome Tab. Running into a problem though:
I'm using a 3.7V 10.000 mAh lipo battery and a switching regulator to boost the voltage to 5.3V through USB. The regulator is rated at 3A and my batterypack can do a sustained 5A discharge.
I've also built into the female USB the little resistors to "let the Tab know" it's connected to something capable of delivering more than 500Ma USB is specced to deliver (this thread). Problem is even with the resistors i'm only getting about 500mA of charge, much lower than when connected to mains... I'm thinking i'm still not convincing the phone it can pull more current, either that or something is wrong with my booster setup.

Hi WarlockM,
It was this one: http://www.lightobject.com/DC-to-DC-power-module-step-up-Input-35V28V-Output-535V-Ideal-for-solar-panel-regulator-P498.aspx
I measured the current coming out of the battery whilst charging: 500-600mA... Figured something wasn't right so replaced the whole setup with an all-in-one solution from ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220712755881&ssPageName=STRK:MEWAX:IT
This one really does a nice job, it charges the phone at 1.5A coming out of the battery so probably a little less going into the phone because of stepup (does require the resistors in USB though). It also smartcharges the lipo batterypack at 800mA straight from USB, or in my case solar panel aswell. What's more it indicates the charge level, so am pretty chuffed.
Will be posting pictures of finished product.
Cheers, Fred
I've been hunting for an extra, high quality, 2A USB charger for my devices - but I didn't want to pay $25-$30 to get a Samsung or Asus 2A USB charger. And then I came across this blog entry by Ken Shirriff where he went and reviewed 12 different USB chargers including genuine and fake apple chargers + other brands.
http://goo.gl/rym3M
Really good and informative post. Definitely recommend a read. For the Cole's notes version, apple makes great USB chargers ... but not the best. The best USB charger in this review actually turned out to be the USB charger that came with the ill-fated HP TouchPad. This charger has very low noise and voltage drop characteristics.
What's more, you can actually get these great HP chargers for $15 on eBay. Or via Kijiji for $15 if you're in the Toronto area.
Mine is off Kijiji and here are logged screenshots of my N7 charging from 12% to 100% with both the Asus charger that came with it and the HP Charger. The HP charger managed to take 20 minutes off my N7's charge time! :good:

I bought the HP touchpad charger for my old Xoom FE. It was a great USB charger, and came with a bunch of heads for global use. Actually seemed to do the 2A charging thing too!

I just ordered my Nexus 7 today and you saved me a bit of searching for a reasonably priced charger. Thanks!
A while back when I got the LG v10, Tronsmart reached out to me and asked if I’d review one of their wall chargers in exchange for an honest amazon review, I agreed, and the charger impressed me so much I bought some others, and now I have the 2 port QC 2.0, the one port QC 2.0, the one port QC 3.0, and the Titan 5 port QC 2.0.
I saw they posted a charging analysis on their site for the s7 and based on my tests, it’s pretty spot on, though I am not going to sit and watch my phone charge for an hour and a half.) One thing I can also say is that they power my aftermarket wireless charges as well, which the factory Samsung one does not.
Just figured I offer op some affordable suggestions for wall chargers even though the hype is on wireless w/ the s7. When I come home from work and need a quick boost before going out for the night, wireless isn’t fast enough.
I have the titan on my night stand and it powers my yootech wireless charger, my tablet, my bluetooth headphones, and my moto 360 sport charger,still leaving me one for toping off the s7 in a hurry. It's a beast.
Here is the Tronsmart analysis, and the pictures below will represent mine.

I'm sure You will find it on Your favorite online shop like e-buy, I have mine from aliexpress
It's best of all I tried, phone reports quick charge, magnets helps to place phone on charger. When phone runs google maps in car and with full brightness it charges very slowly but it's because of intensive usage.
I have about five of them, using not only in car. The only disadvantage is microusb port in charger, usb-c would be perfect.
I tested baseus, ikea and few other qi chargers. Cheap no name gets hot on charge or phone charges very slow on them. On few it's very hard to place phone :/
I'm using the original black xiaomi wireless charger no hiccups or any problems I recommend.
