I have no way of knowing. I do know however that they work and are clean.There are some cosmetic scuffs and scratches. They come with a cooler bag and the three cords seen in the pictures. You will get the cord that plugs into a regular 110 outlet. This is the cord I used to test them. This unit was tested using the 110 power cord to heat up a cup of water.
