A built-in warm-coloured night light, automatic waterless shutoff and preset timer functions support safe and convenient daily use.

Key Features

1500 mL Water Tank and Fine Mist Output

The KC-H121 is equipped with a 1500 mL transparent water tank featuring a wide opening for easy filling and cleaning. It produces a fine mist at a rate of 35–50 mL/h, helping maintain comfortable humidity levels in bedrooms, offices and other indoor spaces. The open-top design simplifies regular maintenance and reduces the frequency of refilling during daily use.

Actual mist output may vary depending on the selected mode, water level, battery condition, ambient temperature, humidity and operating environment.

Dual Mist Modes with Timer Settings

Two mist modes give users flexible control over humidity output. In continuous mode, the unit runs for 8 hours before automatically shutting off. In intermittent mode, the mist alternates between 3 seconds on and 3 seconds off, extending the total run time to 12 hours. These preset timer settings provide consistent operation without manual monitoring.

Battery-Powered Cordless Design

The built-in 2000 mAh rechargeable battery supports cordless operation, allowing the humidifier to be placed on desks, bedside tables or shelves without being tethered to a power outlet. The battery is certified to KC and PSE standards, providing safety assurance for international markets. This design makes it more versatile for home, office and travel use.

Warm-Coloured Night Light and Indicator System

A warm-coloured night light can be turned on or off independently by long-pressing the power button, adding a soft ambient glow suitable for low-light environments. The indicator system provides clear operational feedback: blue for normal operation, flashing red for low battery, red for charging and green for fully charged. This intuitive system helps users monitor the status at a glance.

Waterless Shutoff and Safety Protection

The KC-H121 automatically shuts off the mist output when the water tank is empty, helping to prevent dry operation and protect the unit from potential damage. This feature supports unattended use and adds an extra layer of safety for daily operation, particularly during overnight use.
