Question: Does the nook hd 7'' use the same charger that almost all smartphones use? thanks
Document: I have been using this device for almost a year, and I have decided to give up on it. I mainly wanted it for reading books and magazines because I travel, and I chose the nook because it is compatible with my library system in Philadelphia, it can read books from B&N;, plus if you download an app it can read Kindle books. It does do all of these things, but here is why I have grown to hate it:1. Proprietary charger cable. Really?
Almost impossible to put anything on Nook devices UNLESS it is purchased from Barns & Nobles. Using Adobe Digital editions is not supported. If you use the Nook HD tablet, it will be VERY DIFFICULT, if not impossible to load books purchased somewhere else. Also, Android no longer supports Adobe Flash player, but archived versions can be downloaded and installed on Android devices - HOWEVER, you can't install it on the Nook.
The Nook hd is by far one of the best e-reader/tablet on the market. I purchased one as a gift and after seeing theres,I had to get one for myself. great product!
We have become a nook family. My son had been playing on mine, but is absolutely stoked to have his own. Thanks so much!
This does not happen with my iPhone.I am going back to using the nook and kindle apps on my iPhone, in spite of the small screen. It does mean more page turns, but at least I don't have to manage and pack yet another device and charger when I travel, or be frustrated by an unresponsive interface and buggy Android apps. Plus, the iPhone fits in my pocket.
I have had my original nook since the week it was released. I wanted to upgrade and was considering finally buying an ipad. I just couldn't decide. I loved my nook and had developed a bit of brand loyalty after carrying it with me every day for a few years. my friend took the decision out of my hands when he bought me the nook hd for my birthday. from the minute I turned it on, I was in love.
The Nook HD isn't a staggering value for it's price tag. No, that honor belongs to its bigger brother the Nook HD+ which gives you a device that's just as capable as the Kindle HD 8.9" tablet with an almost $80 price difference, however, that doesn't mean the Nook HD is without value at it's current price sticker of $129.The Kindle HD sits at a similar pricing and sports a processor that's slightly more powerful but the display on the Nook device cannot be beat.
In addition, it will not fit just any usb plug (something to do with wattage, I think). So if you plug the usb end into a travel charger or car charger it may not work. Same thing with using a usb port on a computer. IMO this is a major limitation for an otherwise great device, especially for someone that travels frequently.
I got this for my Daughters Birthday and she loves it.She said it does every thing that the kindle fire hd does and more and that's a good thing to a kid ! So yes that means everything to me when my kids are happy I'm very Happy . :)
Great e reader and tablet. Easy set up and fun to use. Many websites with free nook book s, too.
Answer: The Nook HD uses a proprietary cable.  It comes with a cable and a USB charger but you can plug it into any USB charger.  You don't have to use the one that comes with it.  You do have to use the cable that comes with it.Barry
