The EQUSUPRO is a 150ml ultrasonic diffuser in a black metal shell, priced at the bottom of the category. It mists continuously or on a 30-seconds-on, 30-off cycle, runs whisper quiet, and adds a seven-colour LED nightlight. There is no app, no scheduling and no smart timer; the controls are buttons on the unit. TechGearLab's aromatherapy diffuser roundup ranks it eighth, praising its vivid light patterns but faulting its inconsistent, underwhelming diffusing performance, and the two video reviews in its citation list both land at 4.5.
Full review
A black metal shell instead of the usual plastic dome
Almost everything at this price is moulded plastic, and the EQUSUPRO puts a patterned metal cover over the tank instead, which is the main reason to pick it. The cover lifts off for refilling. It measures about 6.6 inches across and 6.3 inches tall, so it is a tabletop object rather than something that disappears on a shelf. The seven LED colours sit under the cover and read as a soft nightlight rather than a lamp.
A 150ml tank for a room of about 10 square metres
The tank holds 150ml, small next to the 500ml-plus units, so daily use means frequent refills. Coverage is roughly 10 square metres, which is a bedroom, a home office or a bathroom, and the ultrasonic plate throws a fine cool mist rather than a heavy plume. In a genuinely small room the output can be more than you want, and the only way to dial it back is the intermittent mode.
Continuous, or 30 seconds on and 30 seconds off
There are two mist modes and no timer: continuous, or an intermittent cycle alternating 30 seconds of mist with 30 seconds of nothing. If you want a unit that shuts itself down after a couple of hours, this is not it, because the auto shut-off only fires when the water runs out. That suits a diffuser you switch on for an evening and off at bedtime, and frustrates anyone who wanted it scheduled.
Corded, with the adapter routed into the tank housing
There is no battery, so the diffuser lives wherever a socket reaches, and the power adapter runs into the same housing that holds the water, which is worth being careful about at refill time. Dry it before plugging it back in. For a whisper-quiet ultrasonic diffuser with a metal finish at this price those are reasonable terms, but buyers who want scheduling, app control or a tank that survives two nights should spend more.
Strengths

- +Black metal aesthetic with modern appearance
- +Easy to use with simple controls and LED lighting
Watch-outs
- −Limited water capacity at 150ml

How it compares
The EQUSUPRO diffuser's compact design and black metal aesthetic distinguish it from the larger ASAKUKI and LEVOIT models, though its 150ml tank capacity is significantly smaller than ASAKUKI's 500ml. Unlike the Ultimate Aromatherapy Diffuser, it doesn't include essential oils, and compared to the Art Glass Diffuser, it lacks the premium glass construction and more advanced timer options. It's best suited for those who prefer a sleek, basic model without smart features.
