Yeah, thats prolly why, they were just trying to sell me more crap. But, the upside is I bought the Umba and now I can simultaneously charge the ipad and iphone on one device insted of charging them one after another or using two chargers. So, no worries....

I bought the UMBA... it works great.

UMBACHR0102USWG00 - UMBA Charger for iPad & USB Devices 10 Watt (US Version) @ Power Center

BTW, if you order the US Version, they send the global version (with all the world attachments) . BONUS!!!!

I am having the same problems with the charger getting warm. I know the bigger charger is for my iPad but does the cable wire the same?

Just A quick addition:

The charger will get warm, in fact quite hot. Don't use a dock extender when charging, I tried this to lengthen the cable seeing as Apple are less than generous with the supplied ite.

It took nearly 9 hours to charge, without the dock extender, 3.5 hours

Unless they can specifically cite what kind of "long term problems", I wouldn't be too bothered. I've used both iPod and iPad chargers interchangeably with both kinds of devices, and no issues that I've ever encountered (in the "short term", anyway.)

I use my ipad charger for everything that can plug into usb, I have never had any problems with it, also I use a 6 foot usb extension cable while iphone is charging with it and works just fine, been 8 months now and still working.
