The AutoCozie Car Heated Blanket reaches comfortable warmth within 5-10 minutes of activation. Rapid heating technology ensures you feel relief from cold quickly, with full temperature stabilization achieved within 15 minutes of operation.

Yes, but monitor battery levels carefully. The AutoCozie draws 50-100W continuously, which can drain batteries over several hours. Use the automatic timer function to prevent complete discharge, especially with smaller vehicle batteries.

Single control (70×150cm) offers 9 temperature settings for individual use. Dual control (120×150cm) provides 4 settings per side, allowing two people to customize their preferred warmth independently on the larger AutoCozie blanket.

Absolutely. The AutoCozie features automatic timing options and built-in safety fuses. Set the timer for 8 or 12 hours, and the blanket will shut off automatically, preventing overheating while you sleep securely.

Disconnect the power unit before washing. Machine wash the plush fabric on gentle cycle with mild detergent, then air dry completely. Never submerge electrical components, and ensure the AutoCozie is fully dry before reconnecting.

With intelligent timing, battery drain is minimal. The AutoCozie's energy-efficient design uses less power than many devices. For extended use, run your engine periodically or use with vehicles that have auxiliary power systems.

The AutoCozie is designed specifically for 12V DC vehicle systems. Using it with home AC power requires a proper DC converter rated for 100W+. We recommend using it as intended in vehicles for optimal safety.

The built-in replaceable fuse immediately cuts power if current exceeds safe levels. The AutoCozie's thermal protection prevents overheating, while high-temperature resistant materials ensure the blanket shuts down safely before any damage occurs.
