Hi folks. Angela and I purchased a Duosida 16 amp 120/240 volt EVSE for use with our 2015 smart ED as well as our 2016 Nissan Leaf SV. We bought it from Brad at BSA electronics in vegas. Great guy to deal with and builds his own line of open EVSE's as well. Highly recommended.

We have a Juicebox 40 WIFI that we are very happy with but it is too big to be used as a portable unit. We wanted something that would charge the smart at 3.3KW and be small and portable enough to throw in the back of the smart. Although primarily for use with our smart it will be good for the leaf as well although it charges Max at 3.8KW and the leaf can take 6.6. We take the smart south with us behind the motorhome in the winter so its home will be primarily the smart.

One thing about the juicebox is that when on 120 volts it only sends a 12 amp pilot to the car so the smart will never draw more than 12 amps on 120. That way it can be used on 15 amp circuits with no worries of popping the breaker. However the Duosida sends a 16 amp pilot to the car so the car will draw a full 16 amps on 120 or 240 volts. That is handy when you frequent RV parks like us. We can use either the TT30 120 volt receptacle or the 50 amp 240 volt receptacle in in an RV spot. Nice. We carry the original EVSE if we need to plug into 15 amp 120 volt spot.

Here are a couple of meter readings from the Juice box first and the Duosida second. All of these readings when connected to 120 volts.






and the Duosida





Hopefully this info will be useful to somebody out there.

I have one of these units also. Here in Florida we don't have basements so many times the washer/dryer are in the garage (like ours). Also, all our appliances are electric. So many homes have electric dryers. Older homes have the 3 prong 30A outlet (no ground). Newer homes have the 4 wire/prong (with ground). I had originally thought I would unplug the 3 prong dryer plug and insert the EVSE plug. So I bought the Duosida 3 prong EVSE. Upon further review I changed my mind. I did not want to unplug and plug the dryer and EVSE every time I needed a charge. I also wanted to upgrade the dryer outlet to a 4 prong. I did that. I also decided to install another 4 prong outlet near the rear of the Smart so I would not have the cord running all over the garage floor as a trip hazard. Finally, I already knew our electrical panel was quite full (with every legal trick in the book to expand it), I decided to install a 30A double pole, double throw (center off) switch that switches power between the dryer outlet and the EVSE outlet. I don't usually need both the dryer and Smart car charging at the same time since I almost always charge at night. The added outlet was also going to be a 4 prong to conform to current code. Since I already ordered and received the 3 prong Duosida, I made an adapter box/plug. So, whenever I go somewhere that may have either dryer outlet I bring the EVSE and the adapter. Yes, I know the 3 prong Duosida is not the safest because it lacks a proper ground. But the entire setup is all plastic and rubber so the danger is mitigated SOMEWHAT. Please, no endless arguments about these old dryer outlets. If you have the choice, buy the Duosida with a grounded plug (the 4 prong one). It appears to work well after one solid year of use. See attached pics.

Opinions Vary,
Mike
