Very useful. I haven't much tried testing the range limits yet but but may try to do a Canberra run in coming months.
Incidentally, I have a second wall charger installed in Leura but for a few months after end of Feb it will be unavailable due to construction on the site. However, if someone gets in strife in the Blue Mountains or wants to do a range run to Orange before then let me know.
