6. Voltage measuring range: 5 V - 25 V

7. Current measuring range: 0-3.1 A

8. Temperature measurement range(Fahrenheit): - 4 degrees to + 176 degrees (or Celsius version - 20 degrees to + 80 degrees)

9. Color: White / Black Housing Case; Blue or Red Screen      

Features:

1. FAST DUAL USB CHARGING PORTS - Combined 3.1 amps; uses smart technology to ensure each device pulls the right amperage. Charger is powered by the vehicle's cigarette lighter.

2. OVER-CHARGE PROTECTION - auto power off when input/output is greater than safety current, protects against over-heat, over-current and over-charging

3. LED DISPLAY - LED digital luminescence tubes; Display cycles between internal temperature (Fahrenheit or Celsius version), device's charging current, and the voltage of the vehicle's car battery. The LEDs are bright enough to read the display without being a distraction while driving.
