Anyone know how much the Voltec unit puts out? If you think you may upgrade to a different EV in the future, it may be a better value to spend a little more on an EVSE that can handle faster charging. It won't make a difference on a Gen1 Volt, but other/newer cars could benefit. At the very least, you may want to go with a beefier circuit for your EVSE, so you can easily upgrade to a more powerful unit in the future without having to rewire the outlet.
