I got 4 Mason jar units I built myself for less than $40 total. I haven't gotten around to putting it on the truck yet, still waiting on TW to send my chip back from the 3rd reburn and then I gotta get a good baseline mpg with the new chip before installing the HHO unit.
I didn’t buy no plans, just looked at pictures on the net and made mine, pretty cheap and easy to do. Each of my jars pull about 8 amps and the amps can be varied depending on the amount of baking soda or lye I put in the water. The gas produced is very flammable, don’t ask how I know.
