EV charging stations are not on every corner, like all electric car drivers would wish. Being able to plug in anywhere is not an option for most. New York based Leviton has just announced a portable charger that can be used anywhere a common 15A plug is available. The "Evr-GreenTM 120 Level 1 Portable Charger" is small enough to be stored in the EV, light enough to be carried. The business end of this charge is compliant with all major plug in vehicles, aka SAE J1772TM compliant.
Like all level 1 charging devices, there is only so much that can be drawn from a single phase, 15-20A, 110-125V AC plug. With level 1, full charging can take up to 20 hours. However, even if only 1 - 8 hours can be drawn, it would aid in extending the range to the next location. I am officially much less reluctant to purchase an EV.
