How this humidifier scores for different use cases
USB-powered and compact at 8.66 x 5.51 x 5.11 inches, this fits well on a desk. The 1-liter tank may last a partial workday, and touch controls are convenient for office use.
USB-powered and weighing 14.6 ounces, it is portable enough for travel. The 1-liter tank provides adequate capacity for a hotel room, but the dimensions may be slightly large for packing.
The 1000ml tank is too small for overnight use, lasting only a few hours. It has a night light but lacks auto shut-off, quiet operation claims, and a humidistat for bedroom comfort.
No auto shut-off makes this unsafe for unsupervised nursery use. No BPA-free certification, no quiet operation rating, and no humidistat to maintain safe humidity levels for infants.
A 1-liter USB-powered portable humidifier cannot meaningfully humidify a large room. It lacks the tank capacity, mist output, and coverage area needed for spaces over 100 sq ft.
No WiFi, no app control, no voice assistant support, and no remote control. This is a fully manual device with zero smart home capabilities.
Our Verdict
The BusoTh portable humidifier is a basic USB device for small personal spaces. At $11.11, you get a 1-liter cool mist unit with a night light. That is about it.
This humidifier works best on your desk at work or in a hotel room. USB power means you can run it from a laptop or portable battery. The touch control makes operation simple.
The 1-liter tank will need refilling every few hours. You cannot adjust the mist level or set a timer. There is no auto shut-off when the water runs out.
Safety features are missing across the board. No humidistat monitors your room's moisture. No auto shut-off protects the motor from running dry.
For bedroom or nursery use, look elsewhere. You need longer runtime, quieter operation, and auto shut-off for overnight use. This unit lacks all three.
If you need a cheap, small humidifier for your desk, this does the job. Do not expect it to handle anything beyond personal space humidification.

Frequently Asked Questions
Common questions aboutPortable Humidifier, Night Light 1000ml USB (Green), BusoThkvzyge8b1t-12
How long does the BusoTh humidifier run on a full tank?
With a 1-liter (1000ml) tank and USB power, expect roughly 4-8 hours depending on mist output. You will likely need to refill it at least once during an overnight session.
Can I use this humidifier in a bedroom overnight?
The small 1-liter tank and lack of auto shut-off make it a poor choice for overnight bedroom use. It may run dry before morning and has no safety feature to stop the motor.
Does this humidifier work with essential oils?
No. The BusoTh humidifier does not have an aromatherapy tray or essential oil compartment. Adding oils directly to the tank could damage the unit.
How big of a room can this humidifier cover?
This USB-powered unit is designed for personal space use. It can add moisture within a few feet of the device, suitable for a desk area or small nightstand zone.
What power source does this humidifier need?
It runs on USB power. You can plug it into a laptop, USB wall adapter, power bank, or car USB port. No wall outlet is required.
