Can I use a converter to make the One Top DC current? Matthew M. March 04, 2018 10:21 Updated Yes. You can use a converter as long as it can support an appliance at 120 volts and 12.5 amps. Note: The One Top is only rated for AC current use, which means plugging it into a wall outlet. Related articles I have my One Top outside the US, can I return it to you?
