I failed at Volta with 161-1. But yes when you get a chance please try the Providence Place Mall charger (as it looks to be the same kind I have in my area), so we can have more data points. Thanks.
1.61 is working in most cases. However, it does not work on the new free Volta mall chargers (there was an experimental firmware a few weeks ago that made it work, but it seems that fix was not implemented into 1.61).
