"Technically Volt will not accept these Amperage "
the external charger tells the Volt what current in amps to take.
the low is about 6 amps and our supplied 120 volt charger is a low of 8 amps and a high of 12 amps.
The Volt internal charger has a HIGH limit and won't take more even if the charger could deliver the amps.
90% of the charging cord device is safety circuits.
