Can the jump starter start the car in extremely cold weather? – HULKMAN Help Center

Answer:

This depends on the devices you own.

HULKMAN Alpha 85S and Alpha 100 are both equipped with Pre-Heat Technology, which can start your dead car batteries in freezing weather. With these products, you can feel free to hit the road this winter.

We recommend you choose the Alpha 85S or Alpha 100 if you need to start your car in freezing weather.

Pre-Heat Technology:

Your jump starters are made of low-temperature resistant batteries, which can be stored and operated in much lower temperatures than other brands.

With the Alpha 85S or Alpha 100, if the jump starter detects that the temperature is below the lowest operating temperature, it will automatically activate the Pre-Heat Function to warm up and reach the ideal operating temperature.

HULKMAN 's Operating Temperature:

	Alpha 65	Alpha 85	Alpha 85S	Alpha 100
Storage temperature	-40℉~131℉	-40℉~131℉	-40℉~131℉	-40℉~131℉
Operating temperature	-4℉~113℉	-4℉~113℉	-40℉~113℉	-40℉~113℉

If the screen displays the”Error Code 3” message, please follow these 3 steps:

Step 1: Connect the clamps to the car battery properly.

Step 2: The Pre-Heat Function will operate automatically and the “Pre-Heat” icon will appear on the screen when the detected temperature is below the ideal operating temperature.

Step 3: The “READY” icon will be displayed on the screen after preheating, after which you can start your car engine.

Note: Alpha 85 is not equipped with the Pre-Heat Technology.
