Our take on the NOW Ultrasonic USB Oil Diffuser

The NOW Ultrasonic USB Oil Diffuser is a small plastic aromatherapy unit with a 2.37 fl oz (70 ml) tank, USB power, a timer and automatic shut-off. It also has a heating function, which is unusual for an ultrasonic diffuser and lets it warm the oil as well as mist it. It suits desks, nightstands and small rooms where a compact, corded diffuser is enough. Against larger rivals it trades run time and room coverage for size, and its plastic body and single small tank put it below ceramic or wood units on build and capacity.

Questions and answers

How long does the tank last on one fill?
The tank holds 2.37 fl oz, so expect a few hours of mist per fill depending on setting. The timer and automatic shut-off cap a session at 6 hours.
Does the heating function matter?
It warms the oil, which can push scent out faster than cool mist alone. Most ultrasonic diffusers skip heating, so this is a feature rivals do not offer.
Can I run it from a power bank?
Yes. It is USB powered, so a power bank, laptop or standard USB wall adapter will run it. That makes it easy to move between desk and nightstand.
How does it compare with a larger ceramic diffuser?
It is smaller and cheaper-feeling, with a much smaller tank and less room coverage. A larger unit runs longer and looks better on a shelf, but takes more space.
Does it shut off on its own?
Yes. It has automatic shut-off, rated up to 6 hours, so it stops when the timer ends or the water runs low.
What comes in the box?
The diffuser itself. Check the listing for whether a USB cable or adapter is included, since USB power supplies are often sold separately.
