Planning on juicing up your Chevy Volt, Mitsubishi i-MiEV or Nissan Leaf with Tesla's Supercharger? Hold your horses, vaquero. The nighttime unveiling stressed that the quick-charge solution was Model S-friendly, but we should also note that it's only compatible with the firm's automobile. Vehicles from other automakers won't be able to jack into the station thanks to a 20-kilowatt hour converter, which would zap other batteries with too much electricity, and a proprietary plug. Unless something changes, those planning cross-country trips using EVs from other manufacturers will just have to find an alternative to Musk and Co.'s white obelisk.
