New VariCool stock has been added, and new models of VariCool, 5V and 3.7 in white are being built! These will be sharp looking, I can't wait 
smokBox has gone white! New white 5v and 3.7v models are available now.
New white VariCool models are coming soon!
Starting at $22.95
Get More Vapor!

just purchased my varicool today.
excited!!
Oh BTW, love the 1.5 ego mega DCC's. Nothing compares!!!
Thanks smoktek!

Awesome! I'll get it out tomorrow for you. Thanks for your order.
SmokBox VariCool! The efficient variable voltage mod.
New White Model available! This is a great summertime device, it stays cool in the sun.
Read the Vaping Guides Review ! (of black model)
Hand-built and tested to perfection! Run any atomizer/cartomizer with the perfect voltage to drive them! A 3a switching regulator provides true 3.3-6.5 volt output with no heat build up. Up to 95% efficient use of battery energy means longer life!
White Varicool SmokBox
3xAA sized box uses two Li-Ion 14500 batteries which will supply 900mah of battery life for all day use for moderate vapers. Small compact size is easy to carry and use. Don't let the size fool you it packs a big punch at 4-6 volts!
Each box is handcrafted and fully tested.
Features:
What's the difference between a switching and linear voltage regulator?
Technical answer:
Switching regulator - In a switching regulator transistors are turned completely ON or OFF like a switch. When they are on lots of current can flow but there is almost no voltage across the transistor therefore the transistor dissipates very little power. When the transistor is off there is usually a voltage across the transistor but there is no current so again there is very little power. Energy is usually stored and filtered through inductors and capacitors and regulation is controlled by varying the percentage of time on vs. off (duty cycle). The advantage to this is that there is very little heat or wasted power making this design capable of being very efficient.
Linear regulator - In a linear regulator the transistor is turned partly on so as to provide the proper resistance to the load so that the load always sees the same voltage. Since it is partly on there is a definite voltage drop across the regulating transistor and there is as much current simultaneously as the load is demanding. Therefore power is being dissipated across the transistor which turns into heat. This heat is wasted power and the reason that switching supplies are so much more efficient.
Simple answer:
Switching regulator:
Linear regulator: Less efficient (20-60% efficiency)
Less time between recharges
Runs much hotter
Less expensive

Mine should be here today! If you made a transparent orange one I'd buy a dozen : ) I have to say that I'm very impressed with the customer service. I called the other day with a question because I'm too impatient to wait for email replies and Rob actually answered the phone, answered all my annoying questions, and was really polite and courteous. That in itself convinced me to put in an order for a mod, charger, batteries, and a pile of cartos. Thanks again : )
I'm afraid not. I'm still looking for a smaller display w/controller that fit's the bill. I hope to find one someday soon.
i got my SmokBox since 2 weeks. the stealth varicool in black.
first of all it's really an amazing fistfull of power, actually it's the most powerfull mod i have. vaping at 4.2v, it lasts for 2 days easyly. the main body is tightly packed and nicely crafted. the handling of the power regulation is reliable. you can even drop the mod. only the cover (door) is a bit cheesy. you can't see the Led through it, and it does not fit properly, does not close tightly (there is a hole for a screw, but it's not included in the delivery).
anyway, because i really like the inside of the SmokBox (the part with the batteries, the Led and the power regulation), i am in search of a clear door...
any suggestions?

I'm glad you mostly like it
, please get in touch with me via our Contact Us page and I'll help you out with a clear door.
Do AW IMR batteries fit in the Varicool or do I need a magnet?
Thanks!
Thanks!

It seems the pin in my vari cool has been pushed down.. is there anyway to pull it back up?
Button top IMR's will work if they're under 51mm in length, flat top IMR's under 51mm will also work with a small magnet.
Like any 510 connector, the center pin floats in an insulator. It can be lifted a bit with a small paperclip, dental pick, or jewelers screwdriver. Turn the unit off to prevent accidental firing while you're doing this. Just pry up on the edge a little on one side, then the other to lift it only .5mm or so, it doesn't take much.
