Mini humidificateur USB JH-512 – 280 ml, diffuseur d'arôme LED coloré

Many mini humidifiers on the market skimp on tank size to stay compact, which means frequent refills; the JH-512's 280ml tank strikes a middle ground, holding enough water for six to eight hours of run time while staying small enough for a desk or nightstand.

Its cool ultrasonic mist also keeps essential oil compounds intact compared with heat-based burners, since nothing gets scorched in the process. Browse water-soluble options in our Essential Oil collection to pair with it.

Two mist modes and a rotating 7-color LED give it more flexibility than single-setting mini humidifiers, so the same unit can serve a bright desk setup during the day and a dim night-light glow after dark.

For anyone who wants a clean, portable cup design rather than a bulky room humidifier, the JH-512 is built specifically for smaller personal spaces — desks, nightstands, and study corners — rather than trying to double as a whole-room appliance.

280ml Tank Capacity. The 280ml reservoir holds enough water for extended personal-space use without needing frequent refills.

6–8 Hour Run Time. On the low mist setting, a single fill can run for up to six to eight hours, covering most of a work day or a night's sleep.

7-Color Rotating LED. The rotating LED base cycles through seven colors, creating a calming night-light effect without harsh brightness.

Two Mist Modes. Two selectable mist levels let you choose a lighter output for a small desk or a fuller one for a bedroom.

1. Fill Fill the tank to the max line with clean, cool water.

2. Add Oil Add 3–5 drops of a water-soluble essential oil if desired.

3. Connect Connect the USB cable to a power source and press the power button.

4. Cycle Settings Use the control button to cycle through mist levels and LED color modes.

5. Clean Empty and rinse after each use; clean weekly with diluted white vinegar.

Housing. A clean, cup-shaped plastic body forms the 280ml tank and outer shell.

Mist Mechanism. An ultrasonic plate converts water into fine, cool mist across two selectable mist modes; no heat is involved.

Power Source. Runs on USB power (5V/1A), compatible with laptops, power banks, and USB wall adapters.

Not For Ingestion. This is an electric humidifier and diffuser, not a food, supplement, or topical product — the tank is for water and diffused oil only.

After Each Use. Empty and rinse the tank to prevent residue buildup on the mist plate.

Storage. Store in a dry location; coil the USB cable loosely rather than wrapping it tightly.

Longevity. Weekly cleaning with diluted white vinegar helps keep mist output consistent over repeated, regular use.

Don't Run Dry. Avoid operating without water — rely on auto shut-off as protection, not a routine.

Oil Type. Use only compatible, water-soluble essential oils.

Keep Away From Children & Pets. Keep away from children and pets during operation.

Before Cleaning. Unplug before cleaning or refilling.

Fill Level. Do not overfill the tank past the marked max line.

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.
