How to Ensure Your Setup Works Perfectly
Follow this simple checklist to enjoy endless mobile heat:
- Check Your Power Bank: This is the most important step. Your power bank MUST have a labeled Quick Charge (QC) 3.0 or Power Delivery (PD) output port. Check the manufacturer's specifications if you're unsure.
- Get the Right Adapter: Purchase the genuine Smarkey Heated Jacket Voltage Step-Up Cable.
- Connect and Enjoy: Plug the USB-C end into your QC/PD power bank and the DC connector into your jacket. Turn on your power bank, and your jacket should start heating immediately!
Important Compatibility Notes
- ✅ WORKS WITH: Most 7.4V and 8.4V heated jackets, hoodies, and vests.
- ❌ DOES NOT WORK WITH: 12V heated work gear from brands like Milwaukee M12, Makita, Snap-on, Metabo, Craftsman, or AEG. Their connector size and voltage requirements are different.
Why Choose This Solution?
- Longer Runtime: Use a high-capacity power bank to get significantly more heat time than your original, often smaller, proprietary battery.
- Cost-Effective: Save money by using a power bank you may already own instead of buying expensive replacement batteries.
- Convenience: One powerful power bank can charge your phone and heat your jacket, reducing the number of devices you need to carry.
Conclusion
Don't let a simple compatibility issue leave you out in the cold. The reason your heated jacket won't work with a power bank is a lack of the correct voltage and communication protocol. The Smarkey 5V to 9V Step-Up Adapter Cable is the dedicated, reliable, and affordable fix you need.
Invest in this simple cable, pair it with a compatible QC/PD power bank, and never worry about being without warmth again.
