I bought a bunch of Micro USB cables for the same reason. Most of the ones I had on hand didn't have data lines as they were only for charging, which can be fun to troubleshoot as devices connected to the cables just don't show up.

Those are a special kind of evil. I always made sure to properly mark them to not spend time debugging non-working USB connections.

Some of them will let you trick the phone into charging with a full 2/3 amps, even though you've plugged it into a laptop or something that would normally show "charging slowly".

Obviously you're relying on the laptop circuitry to not burn out, but laptops are typically designed with very robust USB circuitry because people often short them out by putting in broken cables.

You might want to keep them around, because sometimes you want to ONLY charge a device, without allowing the possibility of a data connection.
