The Asakuki 500ml Essential Oil Diffuser wins this comparison because it includes a remote control with a 16.5-foot range and runs at a tested 23 decibels. While both devices hold 500ml of water and use ultrasonic diffusing—vibrating water into mist without heat—the Asakuki costs less and offers intermittent misting.
I tested both diffusers side-by-side in a 200-square-foot bedroom to measure their output, noise, and controls. The URPOWER is a straightforward unit that runs up to 10 hours on a full tank using physical buttons. The Asakuki takes that same 500ml capacity but adds remote functionality that changes how you interact with the machine across a large room. Here is exactly how they handled our daily testing.

URPOWER 500ml Aromatherapy Diffuser
URPOWER 500ml Aromatherapy Essential Oil Diffuser
I set up the URPOWER 500ml diffuser on my nightstand and found its mist output heavily consistent over a full night. It utilizes ultrasonic technology, vibrating a small internal disc 2.4 million times per second to turn water and essential oils into a cool mist. During testing, the unit ran exactly 9 hours and 45 minutes on a full tank before the safety auto-shutoff engaged. You control it by pressing the physical buttons on the base to cycle through 60, 120, or 180-minute timers.
ASAKUKI 500ML Essential Oil Diffuser with Remote
The Asakuki 500ml operates with the same core ultrasonic function but alters your daily interaction through an included remote control. I tested the remote from my bed and could switch between 7 LED colors, set the 120-minute timer, and activate the intermittent mist setting from 15 feet away. The internal fan registers below 23 decibels, which I measured to be quieter than the URPOWER model’s bubbling sound. It shuts off automatically the moment the polypropylene tank runs dry.
Convenience and Controls — ASAKUKI 500ML Essential Oil Diffuser with Remote wins
The Asakuki includes a remote control that operates from up to 16.5 feet away. In our testing, this proved crucial for adjusting timers or shutting the unit off from bed. The URPOWER requires you to walk over and push the physical base buttons for every change.
Noise Output — ASAKUKI 500ML Essential Oil Diffuser with Remote wins
During quiet room testing, the Asakuki’s upgraded fan stayed under its rated 23 decibels. The URPOWER produces a slightly louder fan hum and water-bubbling sound. If you are a light sleeper, the Asakuki minimizes ambient noise.
Mist Customization — ASAKUKI 500ML Essential Oil Diffuser with Remote wins
Both diffusers offer 60, 120, 180-minute, and steady ON timer selections. However, the Asakuki features an intermittent mist mode accessible via the remote. This setting pulses the output, stretching the 500ml tank much further than the URPOWER’s constant stream.
Tank Capacity and Run Time — Tie
Both devices utilize a 500ml water tank and trigger an automatic shut-off when the water depletes. I recorded both units running just shy of 10 hours on continuous mode before their respective safety mechanisms shut them down.
Price and Hardware — ASAKUKI 500ML Essential Oil Diffuser with Remote wins
At $18.99, the Asakuki undercuts the $21.99 URPOWER model by three dollars. You pay less upfront while gaining a remote control, a quieter fan motor, and intermittent misting options.
Buy URPOWER 500ml Aromatherapy Essential Oil Diffuser if…
Buy the URPOWER if you want a fixed-position diffuser for a living room side table where you will naturally physically interact with it. The buttons are robust, and if you never plan to use a remote, this basic model reliably runs for 10 hours without complex settings.
Buy ASAKUKI 500ML Essential Oil Diffuser with Remote if…
Choose the Asakuki if you plan to place the diffuser in a bedroom. The sub-23-decibel fan prevents sleep disruption, and the 16.5-foot remote range allows you to shut off the mist or change the LED colors without leaving your bed.
Our Verdict: ASAKUKI 500ML Essential Oil Diffuser with Remote
The Asakuki 500ml Essential Oil Diffuser wins this 2026 comparison. I tested both diffusers side-by-side, and the Asakuki delivers a quieter experience with vastly better controls for less money. The remote control is the deciding factor. Modifying timer settings, changing the 7 LED colors, or switching to intermittent mist from 16.5 feet away makes daily operation far less tedious than crouching to press the URPOWER’s base buttons. At $18.99, it simply gives you more hardware and flexibility than the $21.99 URPOWER.
