As many have heard, Martin Eberhard designed and built himself a mobile charging kit that is more flexible than what the "factory" currently offers. When others saw what he had created they decided they would like to make something similar. Bill Arnett provided some pictures that Doug posted here: EVcomponents has announced that they plan to sell them, hopefully starting next month. From what I know, the production rate isn't yet known, and parts supplies for the kit still need to get worked out, so there could end up being a wait list or delays depending on what happens. I got a chance to look at the manual for the kit, and thought it might be helpful to pass along some observations of what the kit can and cannot do. The EVcomponents link currently includes this: So, basically you have a choice of stubby adapter cables that go from the socket you have found to the "logic box" which then feeds a 20 foot long cable to the Roadster connector. The "logic box" will "know" what source cable you have inserted, and in turn will tell the Roadster what "default" charge rate to pull. In some cases you may need to adjust the charge rate manually from the VDS if the circuit breaker feeding the circuit is too low for the default charge rate.
