Have you ever wondered if you could combine two outlets to charge your EV even faster? Well you can ... sort of... The Quick 220 by Diamond H allows you to "combine" the voltage of two 120v non-GFI outlets to output up to 240v! This gives a doubling of charging speed for most vehicles without needed to have a dedicated charger or outlet installed. Although this is an older model, the newer ones have similar instructions which you can check out here: https://quick220.com/ Always follow the manufacturer recommendations and guidelines when using this product. Remove all other devices from the circuits being used while using this product or it can trip your breaker. Consult with an electrician to ensure that your wiring is up to the task of this continuous load. There are two different versions of the Quick 220, a 15A and a 20A. The 15A charges your Tesla at the following rates: Model S - 7 miles per hour Model 3 - 11 miles per hour Model X - 5 miles per hour Model Y - 10 miles per hour The 20A charges your Tesla at the following rates: Model S - 11 miles per hour Model 3 - 15 miles per hour Model X - 8 miles per hour Model Y - 14 miles per hour
