Label your cables!

• While cables do have individual markings, they should be more obvious and they are not.

Power

• If you plan on using an unknown cable for charging be careful, especially to when charging a computer.
• *NEVER USE A 3A USB C CABLE TO POWER A LAPTOP OR MONITOR*
• Always double check a cable’s capabilities before using to power laptops or monitors
• If you are just performing data transfer, you will typically be ok.

Display

• Some cables are meant for display receptacles only. 
• These are generally Thunderbolt 3 cables and are marked with the Thunderbolt logo.

Buying cables

• Try to use the cable that came with the device when you purchased it. When in doubt, buy cables from the device manufacturer. 
• Read reviews wherever you are buying cables from and make sure people are using for what you want to (read their comments)
• Cables from less-than-reputable sources may have cut corners. In doing that, they may have removed features which keep you safe.
