    Along the lines of the charging cable. One time I was trying to charge my iPad with a white charging cable that came with my iPhone 4. The charging rate was very slow. Then I switched to a 3rd party cable that was marked "2 amp". That one worked really well.

    To this point I haven't figured out if it's the quality of the cable or some sort of pin configuration in the connector that tells the charging device to charge at the higher rate.

    Good point, even if those features cost an hour or more per day, for normal use and charging, the majority of folks aren't even going to notice it.

    I just placed an order for the cable from Monoprice.

    I was going out of town on the 16th so didn't want to preorder for delivery that day. Instead, I placed an order with AT&T for a 16GB Black that Friday morning, knowing it would ship out very quickly. Saturday, when I realized that the iPads were plentiful, I decided that I wanted a 32GB. I verified that AT&T's return policy would give me a full refund if I returned it unopened so I went to a Best Buy on the way back into town & got the 32GB AT&T. When I brought the 16GB to the AT&T store for a refund, the manager was grumbling how they were going to have to open it & do a restore & that they would then have to sell it for $100 less.

    If it was never opened they wouldn't have to open it or do a restore. He was grumpy because he just took a hit to his p&l by a customer who changed their mind and decided to hit his store with the return on an item he never sold.

    I said the same thing -- it's never been opened. He said they would still have to open it because that's the only way they can verify that someone didn't just re-shrinkwrap it.

    Well did he open it in front of you? And he still wouldn't need to restore it' even if he turned it on to make sure it worked.

    I returned a sealed one Best Buy because I wanted to order it from B&H photo in NY to save the $50 sales tax and they actually did open the package (in front of me). Couldn't believe it.

    I don't think it's the configuration because charging rate is controlled by the controller chip in the device. What it probably is is the voltage drop across (either or both) the longer cable or the "gauge" of the pins on the cheaper cables are too thin to handle the higher current and just heat up. I did notice the connector was slightly warmer than I would expect. 2+ amps, which is the charging rate, is high so poor connectors will generate a lot of heat. Think of it as using a too thin & too long AC extension cord on an electric space heater. It can get so hot it could melt and burn. Too much current draw across too thin a cable.

    That's how I picked-up a 32GB iPad2 wifi for $449 from Best Buy last week. They told me it was opened in the store. I checked the serial # and it shows a January 2012 manufacture date, so I have no reason to doubt them.

    After that the next best test is to put the serial number here and check the warranty: https://selfsolve.apple.com/agreementWarrantyDynamic.do

    The warranty begins the first time a new device is activated in iTunes. If it shows as the date you first registered it in iTunes you know it's never been used if it shows before that it usually proves someone else has already used it and returned it.

    When mainstream media latches onto a tech story, it's usually done badly, and almost always missing a few caveats, context or blown out of proportion.

    Same as non-mainstream!

    At least so far no one has claimed that you can fry an egg on the back....

    Just got one yesterday so that son can early-inherit the 2. What a guy!! :nono2:

    Just as a comparison data point, I ran a new iPad2 down to 4% today and started charging its 25 watt-hour battery. After 2 hours, it's at 55%. This is the first charge for that device since I started using it last Thursday.

    So at 10 watts for 2 hours - 20 watt hours, the 10 watt charger isn't cutting it.

    We've kept both iPad / iPad2 and now iPad (3) by the couch with the charger nearby. Never timed either, just plugged them in when they were ~40 - 60% and not going to use it for a while.

    If the charge rate is too high, it can actually shorten the life of the battery.

    Faster rate = fewer charge cycles before significant battery degradation

    So while the 10 watt cube can possibly provide 10 watts, the charging circuitry controls the show -- probably if you've been using the pad and it's slightly warm, it will charge slower because the batteries are warmer.

    Might explain why my (Android) phone's battery life is so sucky... :rolleyes:
