It's definitely not where you'd expect to charge a Porsche, but Electrify America has announced a partnership with Walmart to install charging stations across the country.
Perhaps the most important info from the article:
The partnership with Walmart makes sense because of the locations of the stores off major highways.
Some routes that will have plentiful chargers are Houston to Chicago via I-45, I-35 and I-44, San Antonio to St Louis via I-35 and I-44 and Washington DC to Savannah, GA via I-95.
Another piece of trivia, Electrify America has installed a new charger every 3 days for the past 11 months.
