- 7.4V or 8.4V system
- Compatible with Ororo, Venustas, or similar low-voltage gear
Step 3: Connect and Enjoy
- Plug in the cable to both devices
- Wait for the connection to establish
- Select your desired heat setting

Compatibility Made Crystal Clear
Perfect Plug & Play Partners:
- ✅ QC 3.0 Power Banks with USB-C output
- ✅ PD Power Banks of any capacity
- ✅ Ororo 7.4V/8.4V heated apparel
