Cool car seat with heater function Purchased at the end of August and used for about a month. It has a heater, so it will be comfortable year-round, including the cold season. It is no longer needed as it is standard equipment in the new car I purchased. Used in a non-smoking car. It's almost new, but it's a used item, so please understand no returns or refunds. - Type: Cool car seat - Color: Black - Accessories: Instruction manual - Power supply: Cigarette lighter power - Function: With heater function Heater function type (MTK-KCSH-S12) Product material: Airflow area fabric: 100% polyester, Fabric other than airflow area: Linen Color: Black Seat weight: 500g Power supply type: Cigarette lighter socket Cigarette lighter USB terminals: Top 5V1A output, Bottom 5V2.4A output Power consumption (fan): 12V1A Approximately 12W Power consumption (heater): 12V2.5A Approximately 30W Air volume: 46.5 cubic meters/h Rotation speed (rpm): High 2600, Medium 2460, Low 2300 Noise: 52.2db Heater surface temperature: High temperature Approximately 48℃, Medium temperature Approximately 42℃, Low temperature Approximately 35℃ Automatic power-off function: Fan function 2 hours, Heater function 1 hour Power cable length: Approximately 1m
