Has anyone found a way to speed up the charging of their iPad via the Apple USB 10W charger.

I had my iPad plugged into the charger for at least 8 hours today and it only charged from 25 to 64%.

MacBook Pro 17' 2.33 Core2Duo, Mac OS X (10.6.3), iPhone 3GS, iPad WiFi+3G

    Maybe the charger is faulty? My iPad charges fully in about 2-4 hours, depending on how low I let it get. What you're seeing sounds like what I get if I use the USB port on my Mac.

    You should take the ipad, charger and cable into your nearest Apple store for testing and, if needed, corrective action. It's under warranty.

    You can make an appointment with the expert in the store at www.apple.com/retail and search for your local store on that web link.

    Mine seems to charge up fastest if I plug it into the wall (10w adapter of course) and then turn it off instead of just standby/sleep.

    If you turn it off first, then plug it in, the act of plugging it in will trigger it to automatically turn on. So watch for that.

    Meantime it sounds like you might not be using the 10w adapter... even though you specifically mention that you are. So barring human error on your part (check your cables, check your cables, check your cables), then there is something wrong with either your adapter, your cable, or your iPad. It should fully charge in 4 hours.

    Your not charging it while leaving it playing video or Internet radio are you?

    I had this problem when I didn't use the original cable but some deal extreme cheapie. Still charged. But just 1amp instead of 2.. So half the speed.

    Try and use the original cable that came with the iPad. I used another cable and got the same problem, but when I used the original it worked as it should.

    I've had great success with the OrionGadgets Sync & Charge USB Cable for Apple iPad. I got mine through Amazon http://www.amazon.com/gp/product/B0036BNRGO/ref=oss_product

    To date Amazon does not sell it directly but indirectly through their Amazon Marketplace program. However even with shipping charges I can buy three of these things for the same cost as the OEM Apple cable.

    I know other third party cables have had problems. But I can say from personal experience that this particular cable from Orion works - both to sync and to charge. I've used it on both my 10W iPad and my 5W iPod touch.

    It just works. And it's just inexpensive.

    Well, I just checked and the Amazon Marketplace vendor has changed a bit, and the price is a bit higher. So now I can't buy 3 for the same price as the OEM Apple cable. I can only buy 2.

    Still a good deal.

    It is the cable. I detailed this a while back. The wires in the iPad sync/charge cable are too small to deliver 2.1 amps ( 10 watts ). Most after market cables are worse. They may work for iPhone, but when I hooked to an ammeter I only saw a 7 watt draw with stock cable. With custom cable, I saw a full 10 watts.

    about cable issues and why it is slow:

    about usb driver for PC that can boost charge on PC USB in many cases from 2.5 watts to 5 watts ( so it will charge with screen on and while syncing ):

    I had this problem too. I had to backup everything, reset the whole iPad, wipe it clean to like new, then restore. That fixed it. The iPad gets confused at to it's actual battery level and ends up in trickle charge all the time.

     

    Its a pain. But it worked. Had to do it a few times now. Maybe it's because I leave mt iPad plugged in most of he time, I don't know.

  • Kevin11721 Level 1 Level 1 (0 points)

    If the wires couldn't handle the current they'd get hot and melt. I don't think the wires are the problem.

  • Kevin11721 Level 1 Level 1 (0 points)

    Let me partially take that last statement back.

     

    There could be a problem with an aftermarket cable's design. The data lines are used to negotiate things between the charger and device. A problem there might make the device default to trickle charge mode.

    This thread has been very helpful. I thought the cable wouldn't matter that much but boy was I wrong. I have several iphone/ipad cables, some are stock cables and some are from meritline and ebay.

     

    I compared the power drawn using one of those killawatt meters. And sure enough, it varies from 2 watt to 10 watt. The original cable shipped with iPad is the best. Now I mark those cables by the actual wattage the cable can deliver  so I don't use the wrong cable anymore.

     

    The iPad cable looks just like iPhone cable but it looks like they are not made of the same material.

    I've Run into,this problem recently, myself.  I got a replacement iPad 2 after I'd shattered the screen on the original iPad 2.  I noticed that it charges at a rate of 10% per hour, using the same charging gear as before (including the 10w adapter the first iPad 2 came with).  I drained the battery, charged it up full to calibrate.  Same charge rate.   Even with aftermarket cables I've seen my previous iPad charge at a far faster rate.  I've even tried a different 10w charger that the previous iPod used.  So I'm not sure what's up.  It is charging and the charge holds very nicely for a long time. 

     

    Sadly, for me, replacing the iPad means either driving 3.5 hours to the nearest Apple Store (which is what I did recently) or sending this one in to Apple and being without it or a replacement for a week or two.

     

    After reading this thread, I decided to take a close look at the cables.  I noticed the iPad and iPhone cables-while they look nearly identical-are, in fact, of different diameters, the iPad's being the larger of the two.

    I'm also having the same problem. My original iPad USB cable got lost so I bought a cheap cable coz there's no "cable only" for sale, you have to buy a charger and it's too expensive. I had to charge my iPad for 8 hours.
