A professional job typically signifies that someone is in the highest-level position in his profession, or has the potential for upward mobility with experience. A non-professional job usually means that you perform front-line or lowest-level duties in an industry or company. Laborer jobs and front-line sales and service jobs in retail are listed as examples of non-professional jobs on the University of Illinois website.
The J1772 plug was specifically designed for electric car charging. Problem is, given a typical electric car like the Nissan Leaf, it can take 15 hours to charge the battery from empty to its EPA-rated 75-mile range from that standard household source. Most plug-in cars have a J1772 port, letting them plug into public charging stations.
Mostly, @Anonymous got it right, but a few details. Idling a car for 5-10 minutes will not recharge a battery. It MIGHT replace a bit of the charge lost to starting it in the first place, but even that is iffy. The alternator in your car will need to hit, roughly, 2000 engine rpm to push a charge back to the battery.Keep the top of the battery clean, not just the posts.dling a car for 5-10 minutes will not recharge a battery.
