Tested the unit out. It seems to work ok. Howevery, measuring the current on the permanent 12v feed is round 45mA. That is pretty steep if this thing is mounted in a car. There is a backup battery, which is rated at 150mA. And from what I've seen during the test, there is about 3 hours of standby possible without a power feed. Best option would be to have a larger battery and not connect it to the permanent car bettery to avoid an empty car battery..

  • Treblig On an external 12V supply, mine draws around 20mA while idle and around 45/50mA when sending an SMS (it probably draws a lot more on the internal battery, GSM modules are known to draw up to 2A while SMSing).A larger internal battery would make the tracker bigger but if you really want, you can remove the tracker from its casing and put a larger battery. How you plan to recharge the larger battery is up to you.

  • Professor Fate If the car has a 60Ah battery, at 50mA current , it takes 50 days to empty that.
