Brand new EV owner. I just bought a 2015 B250. All I have is the slow charger that came with it. I may not need more than that, given it will be a true commuter car. I have a 15 amp 110 charger plug very close to my car there's another 110 outlet that's 20 amp, it's not as convenient. Would the 20 amp charge the car substantially faster? I also noticed on eBay for about $200 I can buy a cord that fits my clothes dryer its 220 and not far from where I park. How much faster will that 220 charge than the 15 amps or 20 amps 110? Thanks for your help for the Newbie.

Vic,

Welcome. In general, as my last physics course was back in the day, a 220v charges up to 5x faster. If you are saying you will be charging overnight, you are right that a solid 10 hour charge will restore around 40% of the battery. If you are in warm climate area, 40% will get you over 40 mile roundtrip. So you can top up every night with your existing convenient outlet. I can't comment on 15 v 20 amp but you can search this forum for topics on charging.

It is generally not advised to use a long cord to charge using 220v given a concern about overheating the cord or outlet. I figure one hour gets me 25% of my charge back, so only four hours to get 100% back.

Hope this helps directionally if not specifically.

Enjoy the ride Vic.

At work I charged for free. In my case a 208VAC EVSE worked for me. Now as a retired person I charge at 240VAC at 40A. As much as I drive I could get away with 120VAC trickle charging, I charge at 75% of the 80% default. The EVSE was upgraded to 40A but just because,my 30A EVSE was fine. The Quick Charge Power cable replaced the cable on a EVSE I sold so the charge was minimal. I really have the time to trickle charge

I really like the size of the Quick Charge cable. I purchased a 40A cable from TucsonEV and the cable was huge. Both worked for a fixed installation.
