So you've just picked up your first CBD vaporizer, and you're staring at the charging port. Is it the oval, rounded one? That's USB-C. Or is it the little trapezoid? That's micro-USB. Doesn't sound like a big deal until you're at an airport and realize you forgot the right cable.

Here's the short version: USB-C is the newer standard. It's faster, reversible (no more flipping the plug three times), and it's what your phone and laptop probably use. Micro-USB is older, slower, and the connector is smaller and more fragile.

If you're just starting, you might not care about charging speed. You care about: Will this work when I need it? And for that, USB-C is the safer bet. But don't toss your micro-USB device just yet. It'll still get you through a weekend trip if you pack the right cable.

A quick tip for newbies: before you buy any vaporizer, check what port it uses. Look it up in the specs or ask the shop. It saves you a headache later.
