Bewinner Jellyfish Humidifier 300ml Review: Is This LED Diffuser Worth It in 2026?
A decorative jellyfish night light and aromatherapy diffuser with a very small 300ml tank. It works for fragrance and ambiance but falls short as a real humidifier.

How this humidifier scores for different use cases
The compact size (6.29 x 10.62 x 5.51 inches) and 1.04 lb weight make it a decent desktop unit. Quiet 30dB operation won't disturb coworkers. The 12-hour runtime covers a full workday.
At 1.04 pounds and compact dimensions, it is portable enough for travel. The 300ml tank is typical for travel humidifiers. However, no USB power option is mentioned and no carry case is included.
The 30dB noise level and auto shut-off are good for sleep, but the tiny 300ml tank only lasts 12 hours at best. No timer, no humidistat, and no variable mist control limit overnight customization.
Cool mist and auto shut-off are positive, but there is no BPA-free certification, no humidistat for consistent humidity, and no variable mist control. The small tank requires frequent refilling.
A 300ml tank is far too small for any large room. No coverage area is specified, but at this capacity it can only humidify a very small personal space, not a living room or open floor plan.
No WiFi, no app control, no remote control, and no voice assistant integration. This product has zero smart home capabilities.
Our Verdict
The Bewinner Jellyfish Humidifier is a tiny aromatherapy diffuser with a fun design. Its 300ml tank puts it among the smallest humidifiers you can buy.
At 30dB, it runs very quietly. You can sleep or work without hearing it. The auto shut-off adds basic safety.
The color-changing jellyfish light looks cool on a desk or nightstand. It doubles as an essential oil diffuser for light fragrance.
Here is the problem. A 300ml tank cannot humidify a real bedroom. You get light mist for a small personal area at best.
You also lose features most competitors include. No mist control, no timer, no top-fill, and no humidity sensor. At $34.62, many full-size humidifiers cost less and do far more.
This works as a decorative diffuser and night light. If you need actual humidification for a room, look elsewhere.
What We Like
- Runs at only 30dB, quieter than most humidifiers on the market
- Built-in aromatherapy diffuser lets you add essential oils directly
- Color-changing LED jellyfish night light adds fun ambient lighting
- Auto shut-off turns the unit off when water runs out for safety
- Weighs just 1.04 pounds, light enough to move from room to room
What Could Be Better
- 300ml tank is very small, holding less than most desktop humidifiers
- No variable mist control to adjust output for your comfort
- No top-fill design makes refilling less convenient
- No timer function to schedule on and off times
- No humidity display or humidistat to monitor room moisture levels
