The charging port is the part most shoppers ignore until it fails. But it's the first thing I check when a device comes back for warranty issues. Here's why it matters:

• Micro-USB is older, fragile, and only inserts one way. The little tab inside breaks easily, and the port loosens over time.
• USB-C is reversible, sturdier, and rated for more insertions. It's what your phone probably uses, so you likely already have a good cable.

If you're buying a device to use for months, USB-C is worth the extra few dollars. It's also easier to find replacement cables that actually work well.
