Note that in areas of low signal, the 3G power consumption can be higher. Similarly, if GPS is enabled that can have an affect as well. I’ve never seen it go over about 220mA (and even that was just for short bursts).

Wifi off/sleeping: 8mA (USB 5v) and 19mA (ext 12v)
Deep sleep: 8mA (USB 5v) and <1mA (ext 12v)

(The 8mA is mostly from the CP2102 which is powered off when not in use)

I've just measured the power consumption of the OVMS V3 module using a
bench power supply set to exactly 12.0V.

OVMS consumed:

60mA = 0.72W with WiFi on (AP active) and GSM/GPS modem off
100mA = 1.2W with everything switched on.

This is less than I was expecting, I would take weeks for OVMS to
drain a healthy lead acid battery.
