URPOWER 500ml Aromatherapy Diffuser
Best for: First diffuser, second rooms, tight budgets
The value bestseller — 500ml capacity, adjustable mist and the wood-grain look that started the category, at a low price.
URPOWER is the diffuser that put ultrasonic aromatherapy on every nightstand: a 500ml tank, adjustable high/low mist, 4 timers, auto-shutoff and the familiar wood-grain wrap, at a value price. It lacks a remote and the LED is simpler than ASAKUKI's, but for a first diffuser or a second room, it's a proven low-cost pick with hundreds of thousands of happy tanks behind it.

Frequently asked questions
URPOWER vs ASAKUKI?
ASAKUKI runs longer (16 vs 10 hr) and adds a remote; URPOWER is equally reliable. All-night purists: ASAKUKI. Otherwise compare the two prices on the day and buy the cheaper one.
Runtime enough for a night?
10 hours on low covers most nights start to finish — six hours short of ASAKUKI's 16, but fine for typical bedtimes.
Essential oils only?
Yes — pure essential oils, 3-5 drops. Fragrance/carrier oils can gum the ultrasonic disc.
How to clean?
Wipe the disc with a cotton swab and a little vinegar weekly — prevents mineral buildup that weakens mist.
