ZMax Variable Volt APV Rev. 2, Gun Metal

This special version of the ZMax is exclusive to Madvapes and includes side ventilation slots for additional safety.

This is a variable volt APV made by Smok Tech that takes vaping to the next level.  This is really a variable power mod because you have the option of adjusting either your voltage or your power (watts).  The Zmax adjusts from 3.0 to 6.0 Volts in .1 volt increments or 3.0 to 15 Watts in .5 Watt increments.  The ZMax has a stainless steel finish and a maximum output of 4 Amps. The Rev. 2 the Zmax has one extra menu item (8) which enables you to switch between RMS and mean value voltage monitoring.  The RMS mode is more accurate because it samples the output Voltage repeatedly while it is powering an atomizer or cartomizer.  It is with these measurements that it is able to adjust for heat related Voltage drift.

 The ZMax can read your output voltage, battery voltage and cartomizer / atomizer resistance.  This APV does it all. 

In addition, the ZMax has a native eGo style connector that allows you to use both 510 and eGo style cartomizers, atomizers and tanks without adapters.  The eGo style connector does not have outside threads but typical eGo style parts fit flush down into the recess that is around the ZMax connector. 510 Tanks and other similar 510 items will screw in and be almost flush with the top.

The ZMax will accept Flat Top or Button Top IMR 18650 batteries with the standard end cap. An optional extended cap is available to be able to use 2 18350 IMR Flat Top or 2 18350 IMR Button Top batteries. (2 18350 batteries will not fit with the standard cap)

Never use non-rechargeable batteries in any device. Only use the recommended batteries for this device.

All adjustments and settings are made with the push button switch.  This includes a setting to turn your ZMax off for safe travel in your pocket, bag or purse.

The ZMax includes an instruction manual in English.

There is a 90 Day warranty for device failures under normal use.

  1. Really nice mod, but not Gunmetal Review by zeroarmy27

    I have had this for ~1 week. I am impressed with the LED display functionality, programming, and accuracy. The instructions are terribly written, but the execution on a less expensive display makes me happy.

    I recommend watching the Madvapes YouTube video for the menu system. After a few days, I can navigate the menu without being frustrated.

    The eGo compatibility is *nil* without the 510 to eGo adapter sold here. an ARO Pyrex bottom-coil will not fit without the adapter, but the adapter improves the look by covering the silver bottom cap that holds the coils. My Squid RDA looks really nice on it. Being able to check resistance without breaking out a multimeter is pretty handy. (Posted on 2/11/14)

  2. Great product bad finish Review by Wulf

    I have been using for about 2 months now. The device has worked flawlessly. The only complaint I have at all and the reason for 4 stars, is that the finish fades. Would recommend to any but you might want to buy the stainless version.
    Peace! (Posted on 3/14/13)

  3. Works Well, Looks Awful Review by Sad

    This was a replacement for my stainless Zmax, which I loved but dropped once and broke.
    Gunmetal seemed like a nice change of pace, and it was for about a week until the finish started changing. Everywhere my hands routinely touch the device, the finish is worn off completely, and it's now silver on the lower back an copper under the button. Functionally, it's wonderful, but it looks like hell after maybe a month and a half.
    I'm happy to use it at home because it works very well, but it looks far too raggedy to bring out in public. It was a costly lesson to stick with stainless... (Posted on 1/21/13)

  4. Some information you might need.. Review by Ben

    Got this device and with the lack of information provided I made a couple of mistakes that I figure might save you some time and money since I've already wasted my money.

    1. TrustFire Protected 18650 Battery, 3000mAh will not fit in this device.. well they will, but the cap barely screws in, so I'm trying the IMR unprotected batteries in hopes they will fit better. In the meantime, I wasted money on the Trustfire battery

    2. Watch the Ohms.. I had some 1.25 ohm atomizers and they will not work with this device. It won't even start with ohms that low. From what I've read you have to use cartomizers with at least 1.5 ohms. Anything lower and it doesn't appear to work.

    Hopefully my new order of cartomizers and the new batteries will make this device usable.. so far it's just sitting pretty on my desk.

    The lack of information on this site as far as battery sizes and ohms has cost me a bunch of money, so hopefully this information will help future buyers.

  5. great device besides finish Review by Joshua

    I love the device, only problem is my finish is wearing off like no other but madvapes has told me to send it back and they would make it right. Im waiting for my sszmax to arrive so I dont go without before sending it back though....I dont want to go without my favorite device. (Posted on 12/13/12)

  7. Great PV!! Review by jeff

    been using this for 2 weeks, one great piece of vaping kit, vapes like a champ!!! (Posted on 12/1/12)

  8. Nice Review by Eric

    A little taller than a provari, but lighter and not as big around. Button placement and LED screen are better. The rumors about voltage being off are true, but do NOT let that keep you from getting one. Start low and work your way up till you find your sweet spot. This mod is very nice. I love the way it feels in my hand. (Posted on 11/16/12)

  9. This is an ok device Review by Robert

    as with most mid priced mods this device is ok , Hats off to Mad Vapes for putting this in its proper price range. I would argue that the connection is not ego but rather a 510 with a deep well, as there are no threads on the out side so an adapter will still be needed with some ego accessories.
