A rechargeable handheld fan with 1–100 wind control, a semiconductor-cooled contact plate, and a built-in 10,000mAh battery for backup power.
Adjust the Airflow. Touch the Cool. Stay Powered.
ChillVolt combines adjustable fan airflow with a semiconductor-cooled metal contact plate for brief, localized cool-touch comfort. Its built-in 10,000mAh battery can also provide wired backup power for compatible devices when you are away from an outlet.

When a Regular Handheld Fan Is Not Enough.
Hot summer days create more than one inconvenience:
You may need stronger, more adjustable airflow than a basic pocket fan provides.
Direct cold-touch cooling can feel more immediate when airflow alone is not enough.
Long commutes, festivals, trips, and outdoor plans can leave your phone short on power.
Carrying a separate fan, cooling accessory, and power bank adds bulk.
ChillVolt brings adjustable airflow, localized cold-touch cooling, and backup power into one handheld device.
Cool to the Touch — Without the Cold-Air Hype.
The semiconductor-cooled metal plate is designed to provide a localized cooling sensation during brief skin contact. It does not turn ChillVolt into an air conditioner, and the plate temperature should not be presented as the outlet-air temperature.

Dial In the Airflow You Need.
From a gentle desk breeze to stronger targeted airflow, 1–100 stepless wind control lets you fine-tune the fan for the moment.

Backup Power When You Are Away from an Outlet.
Recharge ChillVolt with up to 18W USB-C PD input. Use its built-in 10,000mAh battery to provide up to 20W USB-C PD output for compatible devices, with PPS support. Compatible Huawei and HONOR devices may reach up to 22.5W via SCP.

*Built-in battery: 10,000mAh nominal cell capacity at 3.7V (37Wh). ChillVolt can provide wired backup power for compatible devices. **Usable output capacity is lower because of voltage conversion, operating losses, and power consumed by the fan or cooling mode.
Three Useful Functions in One 260g Prototype.
ChillVolt combines a high-speed handheld fan, an active cooling plate, and backup power in one device. At approximately 260g in the current prototype, it offers more capability than an ultra-light pocket fan, with a corresponding increase in size and weight.
