I have been asked by quite a few vaporists about power supplies, both AC (home wall plug) and DC (car accessory plug/battery) power options for their 12v log vapes and have come up with the following options that can be used at home or on the go. There will be no soldering or special tools like multimeters, one small flat head screwdriver is all that will be needed for one simple task (a glasses screwdriver will work).
You will need the following for a complete kit that can run 2x logs at once at home (AC)with separate digital control, or one unit while off-grid (DC) after the zombie apocalypse.
1x AC VVPS Variable Voltage Power Supply, goes as low as 3 volts for aromatherapy, (some only go as low as 9.5v);

1x DC VVPS

1x Polarity Sensing LED Power Cable (This is the cable that gets screwed into the DC VVPS)

1x 12v Acessory Power Cable (Plug into DC VVPS and car lighter socket for single DC use)

1x Battery adapter with alligator clips (for clipping directly to any 12v battery)

1x' Splitter Cable (to run 2 logs at once)

Now we need to connect them up,
For Home Use with 1 or 2 logs with different voltages to both with digital readouts for both logs,
1. Plug your AC VVPS into your splitter cable;
2. One male lead off the splitter plug gets plugged to your higher voltage log (with your existing extension cord) and'the other male lead glugs into your DC VVPS;
3. You need to atatch the Polarity Sensing LED Power Cable to the DC VVPS, the red cable gets screw atatched to the + terminal and the black cable gets screw atached to the - terminal (when powered on this LED Cable will glow blue if all is correct and will glow red if you have mixed the + and - terminals, redo if you see red.)
This will atatch to your lower voltage log;
Underside view of DC VVPS where you need to use your screwdriver to tighten the 2 screws;
For DC (car/battery) we just unplug the DC VVPS from the splitter cable and plug the 12v Acessory Power Cable into the DC VVPS, it also gives you a USB 2.1amp outlet for charging other vapes;
And if you want to connect'to a battery, plug your 12v Acessory Power Cable into your Battery adapter with alligator clips to atach directly to a battery (Red clamp on the positive terminal of the battery and the black clamp goes on the negative terminal of battery);
Do not lay your battery on it's side like I have(unless it is special like mine)
The DC VVPS has 2 setting dials on the side to find your preferred voltage, one moves the voltage in large steps and the other is for fine tuning with smaller steps, much rasier to set that than a single large dials on some VVPS units.
So, for about AU$50/US$35 you will be all set for any need power wise for your log, the only other item you could add is a 12v battery and solar panel to be completely off grid.
There are plenty more expensive power/lab supplies available but I believe the above to be the best value for this job, you could save about AU$16/US$12 by not using a polarity sensing power cable but I think it is cheap insurance against stoner wiring jobs, even if you have a multimeter.
