How this humidifier scores for different use cases
At only 0.32 kg and USB-powered, this is highly portable and travel-friendly. The compact size fits easily in luggage, and it works with any USB power source including power banks.
USB-powered, compact at 7.5x7.5x5.8 inches, and lightweight at 0.32 kg make this ideal for desktop use. The 300ml tank can last a partial workday, and quiet 35dB operation won't disturb coworkers.
The 35dB noise level is average, and auto shut-off adds safety for overnight use. However, the 300ml tank provides only a few hours of runtime, requiring frequent refills that disrupt sleep.
Cool mist and auto shut-off are good safety features, but the tiny 300ml tank means very short runtime. No BPA-free certification is mentioned, and no humidistat limits precise humidity control for a baby's room.
The 300ml tank and small ultrasonic diffuser design make this completely unsuitable for large rooms. Coverage area is listed as 196 sq cm, which is negligible for whole-home use.
No WiFi, no app control, no voice assistant compatibility, and no remote control. This product has zero smart home integration features.
Our Verdict
The EVTSCAN 300ml is a tiny aromatherapy diffuser that doubles as a personal humidifier. It works best on a desk or nightstand, not as a room humidifier.
At 300ml, the tank holds about 10 ounces of water. You will refill it multiple times per day. This rules it out for overnight bedroom use.
USB power and 0.32 kg weight make it very portable. You can toss it in a bag and use it in hotel rooms or at your office desk.
The 7-color LED light adds a nice touch for relaxation. The auto shut-off protects against dry running.
This is primarily an essential oil diffuser. If you need real humidification for a room, you need a larger unit with at least a 2-liter tank.
At $19.99, the price matches what you get. It is a small, simple device for aromatherapy and light moisture at your desk.

Frequently Asked Questions
Common questions aboutEssential Oil Diffuser Humidifier 300ml with 7 Color LED Lights, USB-Powered, Auto Shut-Off, 35dB Quiet, for Home Office Aromatherapy Air Moisturizing
How long does the EVTSCAN 300ml humidifier run on a full tank?
With a 300ml tank, expect roughly 4-8 hours depending on mist output level. The manufacturer suggests it covers 20-40 sq meter spaces, but at this tank size, runtime is limited.
Can I use essential oils in this humidifier?
Yes. This unit is designed as a dual-function aromatherapy diffuser and humidifier. You can add essential oils directly to the water tank.
Does it turn off automatically when the water runs out?
Yes. The auto shut-off feature stops the unit when water drops below a safe level. This prevents dry running and overheating.
What power source does this humidifier use?
It runs on USB power. You can plug it into a USB wall adapter, laptop, or portable power bank. No standard wall plug is needed.
Is this humidifier good for a whole bedroom?
The 300ml tank is very small for bedroom use. It works better as a personal desktop diffuser. For full bedroom humidification, look for units with 2-6 liter tanks.
