Best portable dry herb vaporizers under $50

Honest answer first: I couldn't find a single true portable dry-herb vaporizer in this price range — nothing here is a battery-powered herb vape, so I won't dress up a humidifier or a battery as one.

What's actually out there under $50:

• Core [Merlot] — the closest thing to a real vaporizer-style device I found; a compact, pocketable unit, but the listing doesn't state it's for dry herb, so treat it as unconfirmed.
• HIBIBUD "Dry Herb and Wax" unit — despite the name, the specs describe a 500 ml water tank and mist modes: it's a small humidifier, not a vaporizer.
• KETAN portable mist inhaler — a rechargeable fine-mist device for liquids, not loose leaf.

If dry herb is the must-have, the realistic move is a small butane-powered or entry-level battery unit from a specialist vape shop, which generally starts above this budget. Want me to look at what's available just over $50?
