portable heating pad

It seems like you're describing a beauty tool related to eyelashes that has three-speed settings and is rechargeable with electric heating functionality. While I don't have information on specific products, it sounds like you might be referring to an eyelash curler or a heated eyelash curler. These devices are designed to curl or lift your eyelashes, giving them a more defined and attractive look. Here's a general idea of how such a tool might work:

1. Three-speed settings: The multiple speed settings could allow you to customize the intensity of the heat or the curling action based on your preferences or the type of eyelashes you have.
2. Rechargeable: The rechargeable feature indicates that the device is likely powered by a built-in battery that you can recharge, eliminating the need for disposable batteries.
3. Electric heating: The electric heating feature suggests that the device uses heat to help curl the eyelashes. The heat can make the lashes more pliable and easier to curl, providing a longer-lasting curl.

When using such a tool, it's essential to follow the manufacturer's instructions to ensure safe and effective use. Make sure to clean the device regularly, and be cautious with the heat settings to avoid any discomfort or damage to your eyelashes. If you have a specific product in mind, you might want to check the manufacturer's website or product reviews for more detailed information and instructions on how to use it effectively and safely.
