Ultrasonic Aromatherapy Essential Oil Diffuser 300ml Water Tank with Coloured Night Lights, Two Spraying Modes, 5V 1A Micro USB Power, Auto Power-Off, Small Lightweight for Bedroom Office Car Travel, ABS PP
Ultrasonic Aromatherapy Essential Oil Diffuser 300ml with USB Power and Coloured Night Lights

This ultrasonic aromatherapy essential oil diffuser is a compact misting unit designed for small spaces where you want to add fragrance and moisture without taking up much room. It combines a 300ml water tank with a 25-35ml/h spray volume, two adjustable spraying modes, and a 5V 1A micro USB power supply. The diffuser is compatible with any device that has a USB port, including laptops, desktops, mobile power banks, and sockets. An automatic power-off function stops operation after 4 hours in scheduled spraying mode or 6 hours in interval spraying mode. Coloured night lights are built in, and the unit measures 78 x 119mm. It is made from ABS, PP, and electronic components. Because the size is small and the weight is light, it suits a family bedroom, a 20-30 square foot office, or portable car travel.
Features and Construction

The diffuser uses ultrasonic operation with a 1W rated power and a current range of 250-350mA. It runs from a DC 5.0V / 1.0A input, so it can work with common USB power sources. The two spraying modes are controlled by a single button: press once for constant spraying and twice for intermittent spraying. A scheduled shutdown operates at 4 hours for scheduled spraying and 6 hours for interval spraying, after which the unit powers off automatically.
Material and Build
The outer housing and internal parts are made from ABS, PP, and electronic components. ABS and PP are both plastics used in the body, while the electronic components support the ultrasonic misting, USB power input, button control, and timed shut-off. These stated materials form the physical construction of the diffuser; no additional durability or performance claims are made beyond the source specifications.
Size and Practical Fit
With dimensions of 78 x 119mm (3.07 x 4.68 inches), the diffuser has a small footprint that can sit on a desk, bedside table, or car console. The 300ml water tank provides a defined capacity for misting, and the 25-35ml/h spray volume indicates how much moisture is released per hour. The unit is light in weight, which helps when moving it between rooms or taking it in a car. Its small size is intended for a family bedroom, a 20-30 square foot office, or portable car travel.
Uses and Placement

This diffuser is suited to everyday settings where a compact, USB-powered misting device is useful. It can run from a laptop, desktop, power bank, or socket with a USB port, so placement is not tied to a fixed mains adapter. The coloured night lights add a visual element while the unit is in use. The two spraying modes let you choose between constant and intermittent operation depending on how you want to use it.
Event or Professional Use
In a 20-30 square foot office, the diffuser can sit on a desk or side table and run from a computer or power bank. The scheduled shutdown at 4 hours for scheduled spraying and 6 hours for interval spraying means the unit can be set to stop automatically during a work session or meeting. The small dimensions help it fit into limited desk space, and the 300ml tank provides a set water capacity for the misting period.
Everyday Home Use
For family bedroom use, the diffuser can be placed on a bedside table or dresser and powered through a USB socket or power bank. The coloured night lights make it visible in low light, while the two spray modes allow constant or intermittent misting. The automatic power-off function shuts the unit down after the timed period, and the 78 x 119mm size keeps it unobtrusive in smaller rooms.
Benefits and Buying Value

The main practical benefits come from the source specifications: a 300ml tank, two spraying modes, USB power compatibility, timed automatic power-off, coloured night lights, and compact dimensions. These features support simple, flexible use in a bedroom, small office, or car. The diffuser does not require a dedicated wall socket because it can run from any USB port, which adds convenience for travel and desk setups.
Reuse and Low Maintenance
Because the diffuser uses a refillable 300ml water tank, it can be reused across sessions by refilling the tank and selecting a spraying mode. The materials listed are ABS, PP, and electronic components; cleaning should follow only basic, low-risk care tied to those materials, such as wiping external surfaces and handling the tank with care. No specialist cleaning agents or maintenance schedules are stated in the source text.
Why Choose This Product
Choose this diffuser if you need a small, USB-powered aromatherapy and humidifying unit with a 300ml water tank, two adjustable spray modes, coloured night lights, and automatic power-off at 4 hours or 6 hours. Its 78 x 119mm size and light weight suit family bedrooms, 20-30 square foot offices, and portable car travel. The 5V 1A micro USB input works with laptops, desktops, power banks, and sockets that provide a USB port, making it straightforward to power in different locations.
