The adapter lets you power a 3G/4G hotspot with the CANedge2 - with no need for a separate USB power supply.

The CANedge2 can be pre-configured with the name/password of the 3G/4G USB hotspot, enabling the device to push log files to your server via 3G/4G.

Further, the 5V power output from the CANedge2 can be turned on/off in the configuration (incl. via over-the-air updates).

Note: The adapter simply parses power to the hotspot - the CANedge2 connects to the 3G/4G router via WiFi.
