amperage

  1. Amperage question for chargers

    Electric Vehicle Batteries & Plug-In Charging
    I'm looking at the different chargers available. Some of them (such as the GM VOLTEC) are listed as 15 amperage units. Others (like the GE WATTSTATION) are listed as a 30 amperage unit. What's the different? Pardon my noob question, but what does having double the amperage get me?
