Hello guys its a pleasure to be here with all of you, my quotation is i have the original fiat charger which is 12 Amp (is that correct!!) 8 hours charging time .. i need to know if there any faster charger and is that safe on it !
Fiat 500E Charger type !

2 points that I THINK haven't been said here recently & might help eclwncr & other readers:
Volts times amps = watts.
1kW = 1,000W
You can confirm that from any device which shows specs for all 3. Now you can calculate the 3rd number for any device which only gives 2 of the numbers.
An electical device like a car chargecord, toaster, or cell-charger will only draw its own rated power from the source. For example, you plug your 1A phone charger into any 20 or 30A outlet & its fine. Same goes for your 12A Fiat cord, or 16A aftermarket unit plugged into a 30 or 50A outlet.
Voltage, on the other hand: Check the specs on any chargers you can find around your home, like phones, tablet, laptop, toothbrush, etc. ALL of mine say 120-240. That's because many other countries use 240 as household power so it's much cheaper to manufacture only one 240V model & then put a 120 plug on it for North America, which is exactly what Fiat did. HOWEVER, nearly any other 120V device, like a blender or vacuum can CATCH FIRE if you plug one into 240V, which is why it's not too safe to leave a 120-to-240V adapter laying around beside a 240 outlet & a heater or something.

No problem. The OEM Fiat charger limits itself to drawing a maximum of 3.3kW (at 13.75 amps). You can plug it into a 50 amp circuit and it will still pull the same 3.3kW. Think of how you can run a vacuum cleaner from a 120V receptacle and your phone charger doesn't burn out when you plug it into the same receptacle.
However, the 500e can charge at up to 6.6kW. The OEM Fiat charger will only go up to 3.3kW and can't take full advantage of your 240V circuit.
thanks, so where did you get the 13.75 amps figure from for the OEM charger?
My charger has a digital display, when it is plugged in to the wall, and not to the car, it shows the amps at 16 (the larger number) and the voltage which fluctuates from 112 to 126. I presume that is the imput amps. When you connect it to the car, it shows the smaller number at 11.8A in the picture, I presume that is the output. Multiply the two and you get the 1.4Kw figure on the right.
How accurate is the time to charge figure when you have the charger plugged in? Does it just pick up voltage, or does the amperage make a difference as it should?
Is it another guess-o-meter?
When I plug my charger in and the car tells me the charge time was 2hr 10 min. Then I plug the OEM charger and it gives me the exact same time.
Thanks Michael

Without knowing how the car estimate the charging time I would say that it's accurate to +/- 30 minutes.

1.4 kW is what it's putting out. There is some loss in the AC to DC conversion process so the battery is not actually receiving 1.4 kW but closer to 1.1 kW.
Right, and the standard household outlet will only put out 12 amps, which is why the two chargers would have read the same estimated charging time. Interesting to see when they are both hooked up to the 30amp circuit whether the times will be the same or not.

It was assuming a 240V circuit, and the 3.3kW charging rate someone mentioned earlier. 240V will be twice the charging rate of a 120V circuit. You measured 1.8 kW, and 2x would be 3.6 kW. That is close enough to 3.3 kW and the actual number will vary a bit depending on realtime circumstances.
watts = amp * volts, and 3.3 kW is 3300W. So, simple math 3300W / 240V = 13.75 Amps.
If you can manage to get 3.6 kW from the OEM charger on 240V, it would be 15 Amps.

I'm not Fiat, I've got big bones. (and a nice personality)
I don’t think this is correct. At 120v I’m fairly certain 12a is the limit. At 240v with a modified evse the car charges slightly faster than 2x on 120, so my guess is that it might do 16a at most. If it were capable of 30a no one would be buying any 3rd party evses, and it would have fried my 20a circuit.

What 20a circuit?
More accurately, you can plug it into a 30 amp circuit no problem. It will draw about 14 amps from the circuit. It won't "charge at 30 amps".
thanks, I think I have it! Clearly demonstrating my lack of electrical knowledge. I ordered one of the adapters, interested to see if there is any difference in charging time between the OEM and my charger at 240.
I think the time estimation for charging on the dash is also a guess, as it just has 120 or 240V times, with no accounting for the amps.
Thanks Michael

Your 16A unit will charge in 3/4 the time of the 12A OEM, since 12/16 = 3/4.

Right, but those will affect both of the chargers about equally, as will ambient temp, batt temp, etc, so the stock 12A unit should always be 3/4 as fast as a 16A unit.Also note that I wrote "3/4" (25% error margin?) not "75.000%"

I built my own since I was just testing and it wasn't going to be permanent. I have a 10-30 dryer outlet. I also happened upon some 6-20 appliance extension cords on clearance that I'm using to bring power in from a generator. So I ended up with splicing the female end of the 6-20 to the dryer 10-30 and connecting the male end of the 6-20 to a standard 5-15 socket placed in a big box hardware blue electrical box. Took about a half hour to throw together.
If I were doing it permanently, I'd cut out the 6-20 extension cord and wire the dryer plug directly to a 5-20 socket. See post #21 for details.
