One of our favorite applications for our Quick 220® systems is to make an inexpensive and portable EV charging system. If you’re a renter and can’t make modifications to your residence, or you just don’t want to pay the high prices of having a dedicated high-voltage charger installed, then keep reading. We’ll show you how you can use a Quick 220® system, along with some modifications to your existing charging cable, to make a portable and easy-to-use system to drastically cut down the time it takes to charge your EV.

First, if you have a Nissan Leaf, Kia Soul EV, Toyota Prius, Mitsubishi, Chevy Volt, or Honda EV, you need to have your charging cord modified. The best option for this is through EVSE Upgrade. If you have a Tesla EV, you need to purchase one of their Universal Mobile Connectors for either the Roadster or Model S.

Next, you’ll need to attach your charging connector to the appropriate Quick 220® voltage converter. For an EVSE modified cable, you can connect it directly to a Quick 220® Model A220-20L voltage converter. For a Tesla charging cable, since both versions come standard with a NEMA 14-50 plug, you can use a 14-50 to L6-20 adapter also available from EVSE to connect to the A220-20L. The Roadster charging cable, however, can have its plug end changed to a NEMA 6-20 plug with a NEMA 6-20 plug adapter from Tesla. If you go this route, you will instead use a Quick 220® A220-20D voltage converter.

Once your charging cable is connected to the Quick 220® voltage converter, you’ll need to find two outlets in your home that are out of phase. They’ll usually be pretty far apart so we recommend getting one of our packages that includes extension cords. At this point, the light on the front of the voltage converter unit should light up indicating that it is ready to supply power to your charger and EV.

All that’s left is to flip the breaker on the side of the voltage converter and plug the charging connector into your EV. Now, if the two circuits you’ve picked in your home are not rated to at least 20 amps, there is a chance you could trip the breaker when charging. In this case, select a lower charge rate on the charging cable and continue your charge.

That’s all there is to it! You’re now on your way to faster and more economical charging of your EV!
