Is this more energy efficient while charging compared to my 2011 Nissan leaf OEM charger ?

Yes - I originally wrote no - but the answer is YES. The 240 only takes 2 hours tops to charge.

I bought one and I'm sorry I wasted my $$. Thought it would bring my tired Optimas back to life but it didn't. I personally think you're better off with an automatic charger that includes an engine start mode.

In 6 Months and 6500 miles on my Nissan LEAF my electric bill has gone up $25 a month. So 2.3 cents per mile including the Leviton being on all the time for 6 months. There are people who have installed a disconnect switch with a sub-panel next to the EVSE. But I figure that with the EVB40 being on that it will cost me an extra $10.00 per year at 15 watts. Not really sure if it's worth the extra electrical equipment and your time to turn it off every single day for $10 savings per year.

Yes. The original charger is the best way and may be faster than other chargers.

Yup. But the higher Wattage you get the better, and more powerful devices it'll charge faster. Also, if you get a power bank, and change it with the sun, that works even better, becasue then you don't always need to be in the sun. Hope this helps!

Buy the 32 amp unit. It will not charge your current Leaf faster but you'll be glad you have when you lease your next Leaf.

I'd like to know this also. My understanding is anything induction-charged isn't very energy efficient. Convenient and safe, yes, but not energy efficient.

Higher voltage (220 vs 120) and higher current will charge ayour car faster; however check your owner manual to ensure compatibility;

I believe like one of the other responses here, the larger size (3 amp) will be better for use if you do not want to use it as a maintainer. I too have found the newer smart chargers do a better job charging even though they are not excessively high on amperage rating. I have actually been lucky enough to save older batteries by using these charges and allowing them to charge very slow over several days.

Sure does just slower charging is best. great charger wouldnt buy any other brand. And dont buy smart charger or electronic they dont charge dead batteries

I'm using with a US Leaf at 6.6kw. I think the connectors are the same everywhere.

It doesn't, IMO the cells are bogus I could not find any official data on them and the folks at candle power forums seem to agree. If you were to assume 100% charging efficiency the charger would supply 300mA per cell. If you divided that buy 4000mAh you get ~14h more due to charging losses. If you have these cells & they charge in 3h from an empty state there is something wrong with the cells. Even a 2000mAh cell would take ~7h to charge at 300mA

It works about the same, maybe a little slower. I like it because it gives me a little more from the outlet.

No, it does not. It just has an LED to show that it is charging. My Leaf has a web portal which reports the amount of energy used on each trip the car makes. I make the assumption that the amount consumed equals the amount used to recharge.

You don't use any less KWh but my electric company gives me time of day usage rates which are dirt cheap from midnight to 6 AM. I wouldn't be able to get a complete charge in that window without the 220 charger. I thought I didn't need this charger but it is night and day difference from your 110. The charger plus the time of day billing has reduced my electric bill by 10% even as my usage went up 30%.https://energycenter.org/blog/many-california-ev-owners-missing-sweet-spot

According to the information I read the built in charger is a float charger meaning it will not overcharge if left plugged in. There is something else offered if you keep it in your vehicle, they will send you mail when it will need a recharge based on when it was last charged. I might add I am very pleased with the performance of this unit.

The answer really depends on what you plan for the future. The 16 amp will work with your Leaf. It will charge you at 3.3kw. But if you plan to get another car that has a 6.6kw charging unit in the future, you will be limited with your 16 amp charger. Considering the cost of electrical installation and the charger. The difference in price of the charger isn't a lot. Also if the circuit you put in is rated for 16 amps (20 amp breaker) then you have to upgrade the breaker to 40 amp and possibly the wiring to 8 gauge or thicker. Just things to consider.
