We've had some recent innovations regarding VVPS, and will be updating this page soon!
There are a few different ways to adjust the temperature of your vape. The easiest and cheapest solution is to use a dimmer. A dimmer can only turn down the heat, but not raise it. You can compensate for this by starting with a higher voltage power supply, and using a dimmer to go down from there. 15 volts is well above the maximum voltage you would ever need.
If you use a 15v power supply with your UD, you must NEVER run it without the dimmer (turned down appropriately). Please see the Voltage Guide at the bottom of this page. Using a dimmer is by far the most inexpensive and most reliable solution for adjustable temperature, and now that we've added an LED voltage readout screen, they're super easy to use.
Another option for adjustable temperature is a VVPS, which stands for Variable Voltage Power Supply. This type of power supply allows you to control the output voltage to your vape, and thus, the temperature. The higher the voltage, the higher the temperature, and vice versa. Most Underdog users find that the stock wall wart power supply provides the perfect temperature, but for those users who would like to have variable control, a VVPS is a nice addition.
There are three main types of VVPS units that customers typically use with their UDs: Buck/Boost, Tattoo Style, and Lab Style
This type of unit has seemed to be the most reliable out of all the VVPS options we've researched, and requires just a little bit of DIY. To start, you can buy the buck/boost board here on Ebay (Link). Then you'll need a 12 volt power supply and an extension cord. Basically, you need a power supply to feed power to the board, and then you need to insert the board like a dimmer switch in the middle of your extension cord. You'll cut the extension cord in half, strip the wire ends and insert the proper ends into the appropriately labeled In and Out terminals in the board. Then just tighten the screws on the terminals to secure the wires in place. Alternatively, you could just buy a cheap 12 volt power supply and cut its cord in half and do the same thing, but we find that using an extension cord is a more elegant solution. Just plug the power supply into the correct side of the modified extension cord with buck/boost board, and your vape into the other.
Contact us if you run into any problems or need help making one of these.
Tattoo Style VVPS
This type of unit is usually the cheapest option (though the least reliable), and you will need a Tattoo VVPS Cable to plug it into your vape. Here is a popular Tattoo Style VVPS on Ebay. Please note that you do not need the optional bypass plug for this particular VVPS, though some other types of tattoo style VVPS units do. If the VVPS unit has a second port for a pedal plug, you will need to get a bypass plug to stick in the port to make it work. All Hildbrandt VVPS units need a bypass plug. If you're feeling handy and want to build your own cable, we also sell the 1/4" mono plugs and 2.1mm power cord with pigtail ends separately on our Electrical Accessories page.
Lab Style VVPS
This type of unit is typically a little more expensive than the tattoo kind, and you will need a Lab Style VVPS Cable to plug it into your vape. Here is a popular Lab Style VVPS on Amazon. For those of you who think the flames are a bit much, we have had some customers report that they received an all black unit, but no guarantees. :) If you're feeling handy and want to build your own cable, we also sell the banana plugs and 2.1mm power cord with pigtail ends separately on our Electrical Accessories page.
To get the most out of your Underdog experience, we strongly suggest you read and follow these simple instructions.
- Start at 11-12v and let your vape fully warm up. Most UDs reach full temperature by 20 minutes.
- Adjust your voltage up or down (guide below) as needed. Allow 1-2 minutes for your UD to stabilize at the new temp before making further adjustments.
Please note that large or very dense wood pieces may need more time to stabilize.

New Generation Stainless Heater Cartridge Vapes
Old Generation Resistor Vapes Only! 5 min max!
|3v - 4.5v||10v||11v-12.5v||13v-13.5v||14v|
Voltages above 13 volts will accelerate wear and tear on your vaporizer (and use up its lifespan faster), so use accordingly. Voltage of 14 volts or higher will rapidly damage a resistor vape if used for more than a few minutes, and will damage a stainless heater cartridge vape if used at all. Running your vape too hot can damage your vape, will void your warranty and could possibly cause a fire. Please boost your vape temp responsibly.
- Do not run at greater than 13v for prolonged periods of time.
- Do not run at 14v for more than 5 minutes at a time (resistor vapes), and only if absolutely needed. Do not run stainless heater cartridge vapes at 14v ever.
