【Dedicated to Mr. Hikaru!】 Thank you for viewing. I purchased and used this around 2015, but I'm selling it because the cigarette lighter socket was taken by another product. I was using it until recently, so there are no problems with the product. Thank you very much. -------------------------------------------------- 【Product Description】 ■ You can measure the battery voltage and room temperature just by plugging it into the cigarette lighter socket. ■ The color of the characters on the LED display is different for each, making it easy to see. ■ Compatible with 12-24V batteries such as ordinary cars and trucks. ・Measured voltage: 0-30V (Digital number color: Blue) ・Measured temperature: -10-60℃ (Digital number color: Red) ・Input voltage: 12-24V ・Color: Black ・Material: ABS ・Weight: Approximately 24g ※ The string (cord) next to the cigarette lighter plug is a temperature sensor. ※ There is no box, instruction manual, or warranty. I will pack it as simply as possible and ship it. Thank you for your understanding. #CigaretteLighterSocket #Voltmeter #Thermometer #2in1 #Digital #Measurement #BatteryChecker #CigaretteLighter #Car #InCar #12V #24V
