This 120 Doubler rig solves a problem and I use it every day.
Not everyone can access a 240V circuit no matter how much they desire. "Fast" is a relative term but I assure you, those that are still forced to 120V sites will take notice.
This device is useful for Tesla owners living, (or visiting) apartment buildings and condos. For road trips it can significantly cut wait times at charge stops.
With 120V at 12 amps I get about 3.5 Miles Per Hour Charge (MPHC) (the Tesla charge manual lists that as a from-empty 70 hour charge) Very slow because the temperature control pumps and fans consistently draw power first.
With 120V and the VDS set to 16 amps I get about 4.8 MPHC, (the Tesla charge manual lists that as a from-empty 36 hour charge) a huge difference.
With the 120Doubler rig at 16 amps, charge time is now 11 MPHC (the Tesla charge manual lists that as a from-empty 18 hour charge) Any increase of amperage from this point show much smaller gains in charge time. With this setup, charging is basically overnight!
It consists of:
A MC240 or Roadster Foundry cable
A Quick 220
Various Adapters (user wired)
Long heavy duty extension cord(s) to find an out of phase 120V circuit. Mine is 130 feet
The image shows the setup outdoors but this is an indoor rated device. Also note the coiled cord shown is an unsafe practice and no power is present in the picture.
