If 110 volts is available even with a long extension cord the VM SERIES (110 volt, 500 watts) is the way to go. Nothing beats the 500 watts of power that it offers with the exception of the 4.0 Peak HP VAC N BLO. The 12 volt AM SERIES (12 volt, DC) comes in handy when 110 volt AC outlets are just not available (apartment/condo owners). As 12 volt cigarette lighter adaptor models go, this is the best The vacs look identical (and cost the same at retail) with the exception of the motor and cord. VM is 110 volt and AM series is 12 volt.
