Anyone know where to buy a spare charging cable or 3?

The aftermarket cable I ordered from eBay arrived in 8 days from China. That's the good news. The cable does work, but the watched charged slowly compared to using the OEM cable. Not sure if it was a connection issues as the magnet is not as powerful, or just poor quality materials in the cable. BUT, it does work, so it will be handy as a backup/spare cable. The cable does look like the one in the YouTube video posted by ebpman
 
I wasnt paying attention but mine charged pretty fast. the magnets are almost always weaker in these aftermarket cables and i have no idea why. They are definately not as sturdy as the original but like you said they make a great backup

Finally got my eBay cable, and yes I agree the magnets don't hold it on quite as nicely, but it seems to work just as well as the standard charger.
