1. Product Overview

This product is a portable car heater and defroster, featuring an anti-oxidation alloy heating wire for both heating and cooling functions. It can defog/defrost windshields, provide localized heating, and offer natural wind for cooling. It is a localized emergency heating device and is not a replacement for a vehicle's built-in air conditioning system. It is primarily used as a backup for old vehicles with damaged heating systems, emergency defogging/defrosting, and localized heating for the driver or front passenger.

2. Important Safety Warnings

1. Vehicle Compatibility Restrictions:

1. All pure electric vehicles (EVs) are NOT compatible with this product.

2. This product is only intended for use in fuel-powered or hybrid vehicles.

2. Functional Limitations:

1. The primary function of this product is defogging/defrosting. Do not use the heating function for extended periods, as this may cause vehicle circuit overload or equipment damage.

2. This product cannot warm the entire vehicle cabin. Its performance should not be compared to that of a car's air conditioning system. Please do not have unrealistic expectations of heating the entire cabin.

3. Power and Current Limitation Notice:

Some vehicle models have a current-limiting device in the cigarette lighter port, which cannot support high-power electrical devices. This is indicated by the power light turning off a few seconds after the device is plugged in, preventing it from powering on. This is a vehicle limitation, not a product quality issue.

Warm Reminder: This list is for reference only. As automotive electronic systems evolve, more new models may also incorporate current-limiting protection. The most reliable method is to check the label on your vehicle's cigarette lighter port:

·For trucks, check the label; if the power rating is greater than 120W, the product can be used.

·If it is labeled "12V?A", multiply the two values. If the result is greater than 120, the product can be used.

·If there is no label, the vehicle is considered current-limited.

4. Solutions for Current-Limited Vehicles

If your vehicle is current-limited and you cannot use this product directly via the cigarette lighter, you can resolve this in one of two ways:

1. Modify the Cigarette Lighter Wiring: Visit a 4S dealership or an electrician to modify the cigarette lighter wiring, bypassing the current-limiting device and connecting directly to the cigarette lighter.

2. Use a Direct Connection Cable: Run wires directly from the vehicle's battery and connect using a two-wire setup for normal operation.

5.1 Installation

1. Choose a flat surface inside the vehicle (e.g., center console). Peel off the protective film from the strong double-sided tape on the bottom of the device and secure it in place.

2. The base of the device supports 360° rotation, allowing you to adjust the air outlet direction to target the windshield for defogging or the driver/passenger for heating.

5.2 Operation

1. Insert the product's power plug directly into the vehicle's cigarette lighter port to connect to power.

2. The device is equipped with two independent switches:

oMode 1: Natural wind (cooling/ventilation)

oMode 2: Warm air (defogging/heating)The device heats up instantly when turned on.

3. For defogging, direct the air outlet at the windshield. For heating, adjust the outlet towards the driver or front passenger. The 360° omnidirectional heat dissipation ensures high thermal conversion efficiency.

6. Application Scenarios & Tips

1. Winter Defogging/Defrosting: Turn on the warm air mode and direct the airflow at the foggy or frosted windshield. The hot air will dry the moisture and eliminate fog from the source. If the fog temporarily thickens at first, this is normal as the glass temperature rises; continue blowing for 3-5 minutes until the fog completely clears.

2. Summer Ventilation & Cooling: Use the natural wind mode for localized ventilation to relieve stuffiness inside the vehicle.

3. Daily Heating: When the vehicle's built-in heating system is ineffective, use the warm air mode to provide localized, constant-temperature heating for the hands and face of the driver or front passenger.

7. FAQ

1. Q: Can this product warm my entire vehicle?

oA: No. This product is a localized emergency heating device for small areas and cannot warm the entire vehicle. Its performance should not be compared to that of a car's air conditioning system. Please do not have unrealistic expectations of heating the entire cabin.

2. Q: What is its primary use?

oA: It is mainly used as a replacement solution for old vehicles with damaged or ineffective heating systems; for emergency defogging/defrosting; and to provide targeted warm air for the hands and face of the driver or front passenger.

3. Q: Does it have 2 fan speeds as advertised?

oA: Yes. There are two independent modes: one for normal fan-only operation, and one for warm air. It is not a single function with two different fan speeds.

8. Safety & Maintenance

1. Safety Precautions: Do not block the air outlet for extended periods to avoid overheating. Always turn off the device and unplug it before leaving the vehicle; do not leave it running unattended. Install the device away from the vehicle's central screen and flammable plastic components to prevent damage from direct hot air.

2. Maintenance Instructions: Regularly wipe the device's casing and air outlet to keep it clean and free of debris, which can block airflow and reduce efficiency. Do not rinse the device directly with water.

3. Troubleshooting: The product uses an anti-oxidation alloy heating wire, which is durable and has a long lifespan under normal use. If a malfunction occurs, do not attempt to disassemble the device yourself; contact customer service for assistance.

9. Final Summary & Purchase Recommendation

·If you have high expectations for this product, hoping it will match the heating performance of a car's air conditioner, please purchase with caution.

·If you understand that this is a low-power emergency heating/defogging device and can accept its limitations, you are welcome to place an order.

Before purchasing, please make a decision based on your vehicle model and needs. If you have any questions, please feel free to contact customer service
