We are now offering an upgrade for the Tesla MC240 at $700 plus shipping. Expect 1 week turnaround time. http://www.evcomponents.com/ProductDetails.asp?ProductCode=RFMC240 The MC240 from Tesla Motors was the original medium level mobile recharging solution. It came only with a NEMA 14-50 plug. However, it was limited to only 30 amps of recharging ability for a Tesla Roadster. When using that recharging cable, the maximum that a Tesla recharges at would be 240 volts and 30 amps. After our upgrade, your recharging options are much more flexible with many different receptacles (110 to 240) and exactly the same as the Roadster Foundry Mobile Connector that we offer. Comes with adapters for recharging a Roadster using 120 volts or 240 volts at 12 amps, 16 amps, 24 amps, 32 amps or 40 amps. This upgrade for the 240-volt mobile connector (MC240) allows the owner of a Tesla Roadster to achieve maximum flexibility for recharging options while at home or on the road. You ship us your MC240. we will upgrade it and ship it back to you. The Roadster Foundry Mobile Connector allows you to charge a Tesla Roadster at standard electrical outlets. The three adapters that are included in the $700 package are the most common you will find. We also offer two additional optional adapters that may also be useful in some situations.
