The Chevrolet Bolt EV is one of the most impressive electric cars out, boasting a range of 238 miles. Owners of the car will probably not need every one of those miles to get to their daily destinations, but if they do, they can rely on General Motors’ newest accessory: the AeroVironment 32-amp charger, a portable charger that can provide about 25 miles of range per hour at the plug. The new charger will come to dealerships around the U.S in 2017, and will help to relax drivers who fear long trips in their electric vehicles.
