Has anyone tried this?
If you don’t want to install a charging station costing thousands of dollars, you can get a safe, portable 220v converter for a fraction of that cost. With proper extension cords, a plug adapter (if necessary), and a little knowledge, you can charge your EV at home or at a relative’s house using standard household outlets—but charging fast on 220-240 volts.
How does this work? It’s pretty simple, actually. The Quick 220® voltage converter takes 110-120v power from two standard, out-of-phase wall outlets and combines it to produce 220-240v. It allows you to cut your EV charge time down by ½ to 1/3.
That’s a huge savings in time, and it makes the Quick 220® a great charging option for brief stays at someone else’s house. I.e., if you go to a friend’s house for dinner or spend the night at a relative’s house, the Quick 220® can give you a fast, safe 220v charge without any permanent charging equipment installed.
Here’s a video from Internet Guy on how to charge a Tesla with a Quick 220®. While every EV is different, this video serves as a great introduction to this safe, affordable charging method.
