Question 110v charger with higher amps

Would a different 110V charger using more amps work with our vans?

The included charger is 110V and 12 Amps.

This one on Amazon says it will charge up to 16 Amps. Zencar-Portable-Electric-Charging (110V, 15/16A, 25ft), Portable EVSE Home Electric Vehicle Charging Station

I have a 20 Amp circuit so I'm wondering if the van will see the 4 extra amps or not.

It looks fishy. It comes with the 5-15 (15A) plug, to be code complaint it has to limit the current to 80% of the peak capacity, which will be 12A.
The description states:
Quote:
just plug in to your existing NEMA5-15 or 5-20 receptacle or install a 5-15R or 5-20 socket, plug in and start charging. Plug into the NEMA5-20R, the working current will be 16A and plug into the NEMA 5-15R, it will be 15A due to outlet current limited.
This is bull. Outlet can't limit anything, it will supply even 50A- until the breaker will trip or wiring burn. EVSE programming is what limiting the current.
If this EVSE is indeed programmed to pull 16A from a 5-15 plug, it makes it illegal and dangerous. If you plug it in the 5-20 (20A) outlet, it will work (assuming that the EVSE is well built) Your charging time will shorten by a couple of hours.

And actually just so everyone understands, the EVSE programming tells the vehicle what its maximum current is and then the vehicle itself is what actually limits the current. The EVSE itself has no ability to limit current. It can only tell the vehicle what to do and let the vehicle limit how much current it pulls. So stop-eject is correct. If the EVSE has a 15-amp plug then it should tell the vehicle to limit the current to 12 amps.

However, if the EVSE is hardwired or has a plug that is rated at higher than 15A and has an internal contactor rated at > 15 amps then it could conceivably tell the vehicle to pull up to 16 amps which is the highest recommended current level for a Level 1 EVSE. This could shorten the charging time by, at the most, 3.5 hours (assuming a 14-hour charging time at 12 amps).

PacDave, you're correct, my explanation was poorly worded. I think the actual charging time will be even shorter because some power is used to run the car's systems while charging.

I understood what you said perfectly. Just clarifying a bit in case someone gets the wrong notion.
