wire rig

a low, regulated-voltage DC power supply device whose terminals are bare; the purpose of use is to heat the coils of THC oil cartridges. 500 milliamperes (typical old USB port), 1 ampere (iPhone brick), and 2 amperes (iPad brick) are common current supplies. the higher the maximum current, the lower the time needed for a big hit and the higher the chance of overheat--at 2 amperes and 5 volts, one would be putting 10 watts of energy into the cart.
