7. Technical parameters:
1) GPS positioning time: 1 to 5 minutes in the open air (The bad weather will affect the positioning time).
There is no GPS signals indoors.
2) Speed deviation: Since the speed data comes from the GPS satellite, slight deviation is unavoidable.
3) Input voltage: DC 5V Input current: DC 50-120mA Power bank for power supply is supported.
4) Working temperature: -30 to 70 degree
5) Driving data deviation is around 2%
6) All driving data will be cleared when power off except the total mileage.
