ClearMax Acrylic Variable Volt APV

This is a MadVapes exclusive.  Introducing a new variable volt APV manufactured by MadVapes right here in the USA!!!

This is a variable volt APV made by madvapes that uses the same circuit board as the Zmax in a clear acrylic tube.  This is really a variable power mod because you have the option of adjusting either your voltage or your power (watts).  The ClearMax adjusts from 3.0 to 6.0 Volts in .1 volt increments or 3.0 to 15 Watts in .5 Watt increments.  The ClearMax is made of a clear durable acrylic and has a maximum output of 4 Amps

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

With a side mounted button, the 510 connector is free to accept any 510 tank.  And with the power of varaible volt you can use almost any tank or carto you have.  In addition there are ample vent holes in the side of this APV for added safety.

The ClearMax will accept the following batteries: Button Top IMR 18650TrustFire Protected 18650 Battery, 2400mAhTrustFire Protected 18650 Flat Top Battery, 2400mAh,  Ultrafire Protected 18650 Battery, 2400 mAh, or the MarsFire Protected 18650 Battery, 2600mAh.

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 ClearMax off for safe travel in your pocket, bag or purse.

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

  1. Clearly a superior view. Review by Dr. Phil

    I love it. It does it all and has even offered to cook breakfast on occasion. Everywhere I go people see it and ask me what it is and where to get one. I tell them Mad Vapes is where it's at. infinitely adjustable, unquestionably unique and, not that I'm condoning modding a mod but, it literally took 10 seconds to mod this to accept two IMR 18350's for high power vaping, no extra parts required. Clearly a righteous choice for the discerning vaper. (Posted on 1/4/13)

  2. Great for the price but fragile Review by M

    I've had my Clearmax for about a month now. Great performance and I like being able to see the guts. However, the clear acrylic case is a bit fragile. I've already got several cracks 1-2cm long near the bottom screw. i've never been anything but super gentle with the device, but I guess just the slight bumps from setting it on my desk have weakened the bottom. Can't beat the price, esp the special price down to $61! Holy Cow I should have waited! (Posted on 11/23/12)

  3. I really like this device. Review by Ben

    I have owned multiple devices in the several years I have been vaping. This is the first device I have purchased with a booster. All the previous VV devices were stacked batteries. That said, I like this device. The battery life is more than adequate, getting somewhere around 12-16 hours on each battery. I am using the new blue EH batteries.
    It fires constantly. The controls make sense once you use it for a few minutes. The fit and finish is good except the battery screw connector. It needs some improvement on the battery cover.
    Since I have payed far more for other devices, I would recommend this device.
    As a matter of fact, I will probably buy a colored version next. (Posted on 10/23/12)

  4. Good price alternative to the zmax! Review by Michael

    I purchased this clearmax the day they became available. I was impressed with the device. It has the state of the art features at a competitive price. Now that is out of the way. I can tell you my experience. It vaped very well. Like many others I paid little attention to the (voltage) up or down. I mainly used the power or (wattage) up or down feature. I use a 2.0 to 2.4 ohm Ce4. It is one of those devices that you have to wave the cloud away, to see in front of you. Unfortunately that all came to a close 4 days ago. While replacing my 18650 battery. I guess the battery when I reinserted the new one. Grabbed the black ground wire that runs length ways through the battery compartment. It curved in a weird way hence making the battery stuck in the device. Here is the great part. Kudos to madvapes customer service. This happened four days ago. I sent the device back in and Madvapes gave me the choice of giving me a new one or an in-store credit. I elected to buy a zmax only because I can spend a little more right now. My new device will be here tomorrow. I have not read of any body having this problem and I assume it was just a error with this particular unit? I knew when I purchased this unit that after dealing with Madvapes for a while. They stand behind what they sell! I gave four stars only because with this unit, you have to buy an adaptor, if you have an ego skirted atomizer. (Posted on 10/19/12)

  5. Great for the price Review by Scott

    My first try was a bust, as I had a defective unit that wouldn't fire. I returned it at my expense and they said they fixed it rather than shipping a new unit. Now it works great. I prefer the variable wattage option, and for the price it works great. However, the lower wattage setting on the ClearMax and AcryliMax puts out more power than the Kick, Darwin, and Ωpus. So you must downshift the power. For example, on a Darwin I would normally go 6.5 to 7.5 watts and I'm finding on this board that I use 5 to 6 watts. So there's that. Also seems to use up the battery pretty quickly so I'm not sure if it's the most efficient energy setup possible. For the price it's great though. Tough to find a VW unit at this price. One star knocked off for the minor issues as well as the lack of a longer warranty and lack of commitment to fix the units out of warranty. Maybe they will, but as stated in a review of the Zmax, they wouldn't, and this is the same board. But they said they fixed my dud unit and reshipped it to me, so there is hope. Also, for you dual coil users, it goes from 3-15 watts so there's plenty of power for every application I can think of. Takes button or flat top 18650 IMRs. I personally would stick to AW or Panasonic hybrids but I really haven't tried the blue ones MV sells. (Posted on 10/9/12)

  6. Pretty decent for the $ Review by Robert

    This is my first VW device, so I don't have anything to compare it to. It's also my first PWM VV, so I can't fairly compare it to the Provari either. What I can say is that this device provides a quality vape for a reasonable price.

    I have to dock a star for fit-&-finish; mine has a gap on one side of the top cap, and the battery cap threads aren't exactly silky-smooth. However, it does feel fairly solid for an acrylic, and I like the clicky button (which is not uncomfortable to press at all). You might want to find others' reviews of the VMax or ZMax if you're looking for better quality. I'd say this device has a build quality similar to a Lavatube v1 (and its various clones), perhaps slightly better. The internals are the real star here; this is basically a ZMax for about 2/3 the price.

    For anyone else who's looking, I found instructions for the ZMax on another site, which do apply here as the control chip is the same. Click three times to get to the menu, and keep clicking to advance through the options.

    1. Uu - Voltage up
    2. Ud - Voltage down
    3. So - Standby / on/off
    4. Uc - Battery voltage check
    5. Ds - Display change / Resistance Ω/Voltage output/Voltage under load 'live'
    6. Lo - LED on/off
    7. Up - Voltage power (Wattage setting)
    - Po - Constant power operation
    - Uo - Constant voltage operation

    (I presume the capital U is supposed to be a V for Voltage. Keep in mind that P = Power, or wattage.)

    Error codes :
    LOR---Lower resistance indication; If the resistance is below 1.2ohm,the display will show "Low Load".
    LOU---Lower voltage indication. If one 18650 battery voltage is below 3.4V or 2 18350 batteries Superposition voltage is below 6.4v,the display will show "Low Voltage".
    WSC---Short circuit indication. If cartomizer/atomizer output port short-circuit, the display will show "Warning Short Circuit".

    Low Battery Indicator --- When the battery gets low the red lighted pushbutton will slowly flash indicating that your battery is low.

    The menu system is a lot like the Provari's, but without the annoying blank spots between options. It's also more responsive (my Provari seems to "lag" behind my clicks pretty often).

    I'd like for the device on/off option to be a little easier to access (perhaps the first menu option, before voltage/power settings), but I still have to give kudos for the option being there at all. More PVs should have a master on/off switch of some kind.

    I haven't used this enough yet to go into detail regarding the variable wattage capability. So far, I'm enjoying it, and I have a feeling it will be very useful in the future. I don't have a scope to test it with, but it does seem to work well. I noticed very little difference in vape between a 1.5 ohm dual-coil and a 3 ohm single-coil on the same power setting, which I understand is the point of setting a constant wattage.

    Note: Ohm's law says that 4.3V on my Provari should produce
    a little higher than 12W, yet 12W on my ClearMax seems a bit stronger. Not sure what that means, if anything...just an observation. It might have to do with the PWM in the ClearMax, or the accuracy (or lack thereof) of one of the devices.

    I got one of the EH batteries from MadVapes, and it's performing well. AW IMRs are also rocking, as always. My go-to carto is the MadVapes Dual-Coil 1.5 Ohm, and the ClearMax is treating those right, too.

    Neither a plus nor a minus for me, but worth noting: the LED on/off option is for the display, all or nothing. There's no additional LED in the button or anywhere else on the device.

    If you're looking for a high-quality VV, I still think a Provari is the best option out there. However, the ClearMax is a good option for a reasonably priced VV, and an awesome price for a VW. If you're considering something like a ZMax but want to spend a little less, give this one some serious thought. (Posted on 10/3/12)
