Mini USB Cool Mist Aroma Diffuser & Humidifier

Sized for Wherever You Are. Rather than one fixed capacity, this diffuser is available in 300ml and 500ml sizes, so it can be matched to a car cup holder, a desk, or a bedroom nightstand.

USB Power, No Fixed Outlet Needed. USB power means it runs from a laptop, car port, or power bank, which matters for anyone who wants aromatherapy on the move rather than tied to one room.

Built for a Light Oil Mix. Cool mist output is rated around 200ml/h, tuned for a diluted water-and-oil blend, so a few drops from our essential oil collection is generally enough per fill.

A Practical, Low-Cost Pick. At under $15 across every color and size option, it's a low-commitment way to try aromatherapy misting in a car, office, or travel bag before investing in a larger unit.

300ml or 500ml Sizing. Two tank sizes let you match capacity to the space — a smaller 300ml for a desk or car, or 500ml for longer stretches in a bedroom.

200ml/h Mist Output. A mist output of about 200ml/h is rated for personal spaces of roughly 11-20㎡, from a compact bedroom to a home office.

Auto Shut-Off Safety. Auto shut-off is built in to help the unit power down once water runs low, supporting safer everyday use.

Lightweight & Portable. The compact, lightweight housing travels easily between a car, an office desk, and a bedroom without adding bulk.

Fill the Tank. Fill the reservoir with clean water up to the max line.

Add Oil. Add 2-3 drops of your favorite essential oil to the water.

Connect Power. Connect to a USB port and press the power button.

Choose Your Size. Select the 300ml or 500ml version based on where you'll use it — car, desk, or bedroom.

Empty After Use. Empty and clean the reservoir regularly to avoid residue buildup.

What This Is. This is an electric cool-mist diffuser and humidifier, not a consumable, ingestible, or topical product.

Housing. Compact, lightweight plastic housing available in 300ml and 500ml tank sizes.

Mist Mechanism. Ultrasonic-style cool mist mechanism rated at approximately 200ml/h output.

Power. USB powered; check the connected cable or power source's rated voltage before use.

Oil Compatibility. Use only water-soluble, skin-safe essential or fragrance oils, per the oil manufacturer's own guidance.

After Each Use. Empty the reservoir and wipe it dry to prevent mineral buildup or mold.

Storage. Store in a dry place away from direct moisture, particularly if it travels in a car or bag.

Cord Care. Coil the USB cable loosely for storage rather than wrapping it tightly.

Longevity. With regular cleaning, compact diffusers like this typically hold up well over repeated use; we don't publish a fixed warranty length for this listing.

Water & Electricity. Never submerge the base or USB cable in water.

Placement. Use on a flat, stable surface, including in a car cup holder or console.

Fill Line. Do not overfill past the max line.

Around Children & Pets. Keep out of reach of children and pets during use.

Before Cleaning. Unplug the USB cable before refilling or cleaning the reservoir.

Oil Use. Use only water-soluble essential oils; do not apply undiluted oil directly to skin.

Caution. For external use only. Keep out of reach of children and pets. Avoid contact with eyes, broken skin, and sensitive areas. This is an ambient fragrance diffusion device rather than a skincare or massage product, so it is not intended for direct application to skin.
