Early iPad User Complaints: Weak Wi-Fi, Charging Issues

PinkyMacGodess said:
The one thing that I'm still not sure of is when I synced my iPad tonight, under the STORE section I have the generic 'Purchased' and another one that is 'Purchased on Dookie'... Why should it be separate?

Usually "Purchased" are things bought via your computer and "purchased on <device>" are items you bought on <device>'s store apps.

Certainly this is the case with my computer and our 2 iphones. My itues has 4 areas
purchased
purchased on iphone_1
purchased on iphone_2
purchased on AppleTV
 
Anyone tested if the iPad will charge with the new Macbook Pros (specifically the 17")?
 
Still Having Problems?

I notice that the last posting here was last week; are you folks with iPads still seeing these issues of poor/spotty wi-fi performance?

I have an iPad 3G on order, and am hoping that any hardware issues (if there were any) have been recified. If the issue is in software, I have no doubt that the fix will appear in short order.

Well, the port can't be 9v, for sure. But assuming it's set to the right voltage, I don't think there would be an issue sourcing 6A if that was the current drawn by the device plugged into the port. I should think current requirements in the spec. are minimum requirements. (Of course, inrush current must be limited, but as long as the port sources the minimum specified in the spec. [so the device can operate], I can't see a reason not to supply more if the device actually demands it because its input impedence is high).

All standardized electrical power delivery methods are current limited BY DESIGN. Just like 15A circuits in your home, your USB connection is current limited because they had to draw the line somewhere so folks could reasonably design and build USB devices. Current heats up conductors. If you don't limit the potential delivery, you could heat conductors of improper size to the point that they start a fire.

Once a standard is set, anyone who makes a USB device knows just how big the cable (and internal connections) has to be. If the device shorts out they can be sure that the current limiting will keep the whole mess from catching on fire.

In your world where current isn't limited we'd see USB devices burning down homes and killing people.

Having a USB port that delivers 4x the standardized, specified maximum current to any device that requests it is asking for trouble.

Except for the pathetically short cable. And don't even think about using a USB extension cable - if you do... it won't charge. :)

Well gee, let's see, here's Apple's dilemma:

-They knew that the iPad would need more power to charge it

-They knew most people would want to hook the ipad into their computer via USB to sync

-They knew people would bitch and moan if they changed the "dock connector" standard currently in use with the iPod Touch, iPod, and iPhone

-They had to stick to the Apple "minimalist" design

So, they had to stick with USB, but unfortunately USB doesn't give off enough power, so they had to use a more powerful wall charger. The trade off is that using a standard dock/usb cable, it can only be a certain length before they have issues.

So... That is why we have a short cable... And why you can't charge efficiently using the USB on your computer.. Loose Loose, but also win/win given we get to keep the "Standards" of the dock connector and continue using all our USB cables that came with our other Apple products. ;)

However, I do have a solution for you. The power cable that comes with the Macbook/pro computers also works with the charging adapter for iPad. I have two of them, one behind my couch and one behind my pillow in bed, so that I can easily pop either my Macbook Pro charger into it, or the iPad charger. :) That gives you much more length! Unfortunately if you don't buy a Macbook product, you'll need to buy the ipad power adapter with the longer cord here:

Sweet! Thanks! Too bad I can't just buy that fancy power cable minus the brick.

I'm orderin' one right now...
