ThermaCore™ Smart Heating Rod

ThermaCore™ Smart Heating Rod — Warm Up in Minutes

A cold doll tunnel is an uncomfortable one. This USB heating rod warms your doll’s internal cavity to a comfortable 112°F (44°C) in just 5 to 10 minutes, with automatic temperature control that keeps it at the right temperature without any risk of overheating.

• Reaches the Right Temperature, Then Holds It
  The built-in electronic thermostat regulates heat automatically. The indicator light turns off when 112°F is reached and reactivates if the temperature drops below that point — maintaining consistent warmth throughout use without any manual adjustment.
• Aluminum Alloy Tip for Deep Heat Transfer
  The aluminum alloy tip conducts heat efficiently deep into the cavity, ensuring the warmth reaches further rather than staying concentrated near the opening.
• IPX4 Waterproof
  The rod and wire interface are waterproofed to IPX4 standard, allowing the connection area to be rinsed with water during cleaning without risk of moisture damage.
• USB Powered
  Compatible with any 5V/2A USB power source — wall adapters, power banks, or USB ports. The 100 cm cable gives you comfortable reach during use.

How to Use
Connect to a 5V/2A USB adapter. Apply lubricant and gently insert the rod into the doll’s tunnel. Wait 5 to 10 minutes for the cavity to reach optimal temperature. After use, unplug the adapter first, then the USB cable. Allow to cool fully before cleaning or storing. Do not exceed 30 minutes of continuous heating.

Warm up fast. Stay at the right temperature. Every time.
