I used to have a few USB charging cables, that already had their data lines shorted. These are really useful for charging phones at the full 1A rate rather than 500mA (allowing me to, for example, use Navigation and keep my phone charged).
I lost a couple of those cables, and now I can't find any. I'm looking for a 4-5 ft charge-only USB cable. I know its possible to mod regular cables, but I'd much rather just buy some.
