Frequently Asked Questions

Q: How do I know if my heated jacket is compatible?
A: Check your jacket's voltage rating (must be 7.4V or 8.4V) and power consumption (must be under 12W). Most Kobalt and Smarkey jackets are compatible.

Q: Can I use this cable with 15W heated jackets?
A: No, the cable is specifically designed for jackets under 12W power consumption. Using it with higher-power jackets may not work and could potentially damage the cable.

Q: What capacity power bank should I use?
A: For all-day use, 20,000mAh is recommended. For shorter periods, 10,000mAh may suffice. Choose based on your typical runtime needs.

Q: Is this cable safe to use in rain or snow?
A: While the cable is durable, we recommend keeping electrical connections protected during precipitation. Avoid exposing connections to direct moisture.
