I hope you have at LEAST an 8 hour job and a 220v outlet handy...
what makes you think an employeer will allow them to recharge?
what makes you think any city will not impose a plug inspection tax on all outlets?
How about converters that take two 110 and make them a 220?
Stealing electricity is going to be an interesting crime to punish.
I have an 8 hour job, however, the building that where I work at has a parking garage and I doubt the building management is going to allow car charging outlets for free...
