About: USB Rechargeable 300ml LED Aroma Humidifier

300ml Water Tank

A 300ml tank holds enough water and oil for extended ultrasonic misting between refills.

≥250ml/h Mist Rate

High-output ultrasonic misting freshens and lightly humidifies small-to-medium rooms faster than low-output units.

Under 36dB Operation

Ultrasonic (not fan-based) misting keeps noise low enough for bedrooms, nurseries, and focused workspaces.

Auto Shut-Off Safety

Built-in auto shut-off helps prevent overuse once the tank runs low, adding peace of mind during unattended sessions.

Product Details

A desk that's been dry and stale since the office AC kicked on, or a bedroom that could use a softer glow before lights-out — this is the kind of space the USB Rechargeable 300ml LED Aroma Humidifier is built for. It's small enough for a nightstand or a monitor shelf, and it runs on USB power, so there's no need to hunt for a free wall outlet.

The tank holds 300ml of water, enough for the ultrasonic disc to hold a mist rate of roughly 250ml an hour without needing constant attention. Seven LED colors cycle through the base, or you can hold on a single shade that matches the room. Everything runs on standard USB power, so it plugs into a laptop, a power bank, or a wall adapter.

A few drops of a light, water-soluble essential or fragrance oil turn the plain mist into a scented one; the ultrasonic mechanism handles diluted oils well but isn't meant for thick, undiluted blends. That makes it a natural fit for anyone who already keeps a rotation of essential oils on hand and wants an easy way to use them beyond a diffuser stick or a warmer plate.

For a single desk or a small bedroom, the 300ml tank is typically enough to run through a work session or a full night without a refill, especially with the auto shut-off feature standing by if the water runs low. If a household is looking to scent a larger open room instead, a higher-capacity or wall-mounted diffuser will generally keep up better than a compact unit like this one.

Its BPA-free housing and light weight also make it easy to carry between rooms, tuck into a travel bag for a weekend trip, or pack up as a gift for someone who likes a calmer, better-scented space without extra clutter on the nightstand.

Pair it with a light-bodied pick from our essential oil collection to get the most out of the ultrasonic mist.

Why Choose USB Rechargeable 300ml LED Aroma Humidifier

Beyond a Plug-In Warmer. A plug-in oil warmer only releases scent from residual heat and offers no humidity, no mist, and no lighting. This ultrasonic humidifier adds moisture and a visible 7-color glow to the same footprint, doing more with one device.

A Useful 300ml Capacity. Many compact USB diffusers hold well under 200ml and need refilling every couple of hours. The 300ml tank here runs longer between fills, which matters for a desk that stays occupied all day or a bedroom used overnight.

Built for Real Essential Oils. Because the ultrasonic disc is designed for a dilute water-and-oil mix, it pairs well with a light-bodied pick from our essential oil collection rather than a thick, undiluted oil that can clog the misting element.

BPA-Free Housing. The BPA-free plastic housing keeps the unit lightweight enough for a nightstand or travel bag, without adding the bulk of a full-size humidifier.

USB Rechargeable 300ml LED Aroma Humidifier Benefits

Whisper-Quiet Misting. Ultrasonic mist technology runs at under 36dB, quiet enough to keep running through sleep, video calls, or focused work without becoming a distraction.

7-Color LED Glow. Cycle through seven LED colors or settle on a single steady tone to match the mood of a bedroom, reading nook, or desk setup.

Auto Shut-Off Safety. The built-in auto shut-off feature helps the unit power down once water runs low, reducing the risk of running the tank dry unattended.

Cord-Free USB Charging. USB rechargeable power means no dedicated wall outlet is required, so the humidifier can be moved between a desk, nightstand, or shelf as needed.

How to Use USB Rechargeable 300ml LED Aroma Humidifier

Fill the Tank. Add clean water up to the 300ml fill line marked inside the tank.

Add Oil. Add 2-3 drops of your chosen essential or fragrance oil directly to the water; adjust up or down to taste.

Choose a Mode. Select your preferred LED color, or leave it cycling, then power on via the USB connection.

Empty After Use. Once finished, power off, empty any remaining water, and wipe the tank dry before storing.

Shelf Life & Storage

After Each Use. Empty any remaining water and wipe the tank dry to prevent mineral buildup or mold growth between sessions.

Storage. Store in a dry place away from direct moisture and out of direct sunlight when not in use.

Cord Care. Coil and store the USB cable loosely rather than tightly wound, to help it last.

Longevity. With regular cleaning and proper storage, ultrasonic diffusers of this kind typically hold up well over repeated use; we don't publish a fixed warranty length for this listing.

Safety Instructions

Water & Electricity. Never submerge the base or the USB cable in water, and keep both away from splashes.

Placement. Run on a stable, flat surface, set back from the tank's edge so it can't easily be knocked over.

Fill Line. Do not fill past the marked maximum line.

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

Before Cleaning. Power off and disconnect the USB cable before refilling or cleaning.

Running Dry. Ultrasonic misting elements can be damaged by running without water, so avoid powering the unit on an empty tank.

Oil Use. Do not apply essential or fragrance oils undiluted directly to skin; this device is for ambient room diffusion only.

Caution & Disclaimer

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.

Disclaimer. Our products are not intended to diagnose, treat, cure, or prevent any disease. Always consult with a healthcare professional before use, especially if pregnant, nursing, or under medical care. Individual results may vary.
