Crystal Salt Stone USB Humidifier Diffuser with LED Lamp for Home and Bedroom

This crystal salt stone humidifier brings together three practical functions in one compact unit: it humidifies the air, diffuses essential oils, and serves as a gentle crystal lamp. The porous structure of the salt stone absorbs aromatherapy essence and releases it gradually, while the ultrasonic atomiser produces a soft, fine mist that spreads easily through a room. Powered by USB at 5V, 1A, and 2W, it fits neatly on a desk or bedside table. The 260ml water tank provides up to 4 hours of continuous spray or 8 hours of intermittent spray, making it suitable for a work session or a night's sleep. Low-noise operation means it can run quietly in the background. Available in Blue, Pink, and White, it measures 125*77*77mm and weighs 280g net. Whether you want to add moisture to dry air, enjoy a favourite fragrance, or have a soft night light, this unit covers those needs without taking up much space.

Features and Construction

The humidifier is built from ABS, PC, silica gel, and electronic components. These materials form a compact body that houses the water tank, ultrasonic atomiser, USB port, and LED lamp. The crystal salt stone sits within the design and acts as the aroma diffuser element. Each part has a clear role: the casing protects internal parts, the silica gel helps seal and stabilise, and the electronic components drive the mist and lighting. The overall construction is straightforward and designed for desktop use.

Material and Build

The outer shell uses ABS and PC, which are common plastics chosen for their rigidity and light weight. Silica gel is used for seals and non-slip details, helping to keep the unit steady on smooth surfaces. Electronic components include the ultrasonic plate, the USB port, and the LED circuitry. The crystal salt stone is a natural porous material that absorbs essential oils; over time it releases the fragrance gradually. No performance claims beyond those stated in the source are made here. The unit is supplied with a cotton swab for cleaning and a charging line for power.

Size and Practical Fit

With a product size of 125*77*77mm and a net weight of 280g, this humidifier occupies a small footprint. The colour box measures 135*82*80mm, so the packaging is similarly compact for storage or gifting. The 260ml water tank is sized to deliver up to 4 hours of continuous spray or 8 hours of intermittent spray. It runs from a 5V, 1A USB supply with a rated power of 2W. The USB port makes it easy to power from a laptop, power bank, or wall adapter with a suitable USB outlet.

Uses and Placement

This unit is intended for indoor environments such as bedrooms, home offices, and living areas. Its functions suit moments when you want to add moisture to the air, enjoy a subtle fragrance, or have a low-level light. Because it is USB powered, placement is flexible wherever a USB power source is available. The low-noise operation is a practical point for night-time or focused work. Colour choices let you match the unit to a room's existing decor.

Event or Professional Use

In a professional setting such as a desk at home or a small office, the humidifier can help keep the immediate air from feeling overly dry. The aroma diffuser function allows a preferred essential oil to be released gradually through the salt stone. The soft spray is designed to disperse easily, and the low-noise operation means it does not add distracting background sound. The LED lamp can provide a gentle light if needed. The compact size means it does not encroach on workspace.

Everyday Home Use

At home, the unit can be placed on a bedside table, shelf, or sideboard. The 260ml tank supports up to 4 hours of continuous mist or 8 hours of intermittent mist, which can cover a reading session or a night's sleep. The colourful lights act as a gentle night light that is not dazzling. The crystal salt stone releases fragrance gradually, so the scent is present without being overpowering. Available in Blue, Pink, and White, it can blend with different colour schemes.

Benefits and Buying Value

The main value comes from combining humidification, aroma diffusion, and a night light in one USB-powered device. It reduces the need for separate units for each function, which saves space and simplifies use. The 260ml tank provides a defined run time, and the USB power format means it can run from common power sources. The salt stone is reusable in the sense that it can continue to absorb and release essential oils over multiple uses, though the exact lifespan is not stated in the source. Maintenance is limited to rinsing the tank and using the supplied cotton swab for cleaning.

Reuse and Low Maintenance

The crystal salt stone can be reused with essential oils; it absorbs the oil and releases it gradually over time. The water tank can be rinsed between uses, and the included cotton swab helps with cleaning small parts. The unit is powered by a USB charging line, so no specialised batteries are required. Since the source does not specify a replacement schedule for the salt stone or detailed care instructions, only basic rinsing and wiping are recommended. The materials are standard for this type of device.
