Madvapes Variable Voltage Box Mod Kit

[tumbafox]

I just completed building my second Madvapes VV Box mod which I bought for $17.99. The only other thing you need to buy separately are two 14500 batteries which I already have plenty of. And you need a charger of course.

After watching a few hours of soldering instruction on You Tube I got the courage to build my 1st one and then my second one. Both work flawlessly so far. Even though the regulator chip gets hot it does not seem to matter. These things are designed to get hot. I once got a second degree burn by touching an Intel Pentium Processor chip that did not have a heat sink on it. The early Pentiums did not use heat sinks.

The first one mod took about an hour to build because I had to repair a connection mistake. I soldered a wire into the wrong hole on the circuit board. Thank god for desoldering braid.

The second Box Mod took about 30 minutes to build.

I have to say the mod works great.

I get voltages ranging from 1.3 to 7.2 volts using the wheel adjustment using fully charged batteries.

Since there is no LED, you have to adjust the voltage to taste by turning the potentiometer wheel which works smoothly.

The mod works with all resistance attys and cartos and so far no burnouts.

It has an on/off switch so there is no accidental pressing the vape button while its in my pocket.

I have a Provari and I cannot tell any difference in vape quality.

Tools Needed:
Soldering Iron
Glue Gun
Box Cutter for plastic trimming
Wire Stripper

Materials Used:
28 gauge #60 resin core solder.
Glue Stick.

The only wish I have is that they would make a large battery version instead of the two 14500 battery version.

I did also buy the separate regulator kit ($7.99) which includes everything you need to build your own VV mod anyway you want. You just need to buy a separate low amp switch for a buck or two and a project box or some other container to pack it all in to.

I am thinking of buying a 5000 mah Trustfire 26650 battery and going to Home Depot to find some sort of way to build a custom mod using the Madvapes VV regulator kit. Possibly using some Plastic or Copper Plumbing supplies I think I can get it done. Once wired, the circuit board would easily fit into a tube the width of a 26650 battery which would be 26mm. All I need to do is drill an 11/32" hole for the battery connector, make a small round cut out for the voltage wheel and drill a tiny hole for the switch. A couple of battery contacts, a spring, maybe a foot of 26-28 gauge wire and that should be all I need.

I will post again if I get it done.

But the review is that so far after two weeks is that Madvapes delivers.

Excellent Product. Amazingly cheap. I would highly recommend this product to anyone with basic soldering skills. Online instructions are adequate.

Nice review thanks ive been up in the air about getting it but I think ur review has convinced me

Thank you. I built two so far and I bought 1 separate regulator kit because I'm thinking of making a custom mod using a 26650 or even bigger battery. The two I built are still working great. They work as well as my provari. But you need good soldering skills. I'll probably buy some more kits myself to build for friends. A great feature is the on off button so the unit never accidentally fires in my pocket.

1 Tip. I fill the bottom of the battery connector with hot glue so juice can never leak into the guts.

I don't mind the absence of an LED since the POT wheel allows you to easily adjust to taste and throat hit.

If you can't build it yourself I think they sell them pre assembled for around $35.00

And they never roll off the table like my Provari has a habit of doing.

Also, since the batteries are in series only use PCB batteries or you may risk explosion.

Madvapes Rocks.

these mods are awesome for what they are...inexpensive, no frills, entry level variable voltage

I've had 2 of them and they lasted me roughly 6 months each (the second ones hanging on by a thread)...now some people would be all bummed out about that...I'm not in the least

I used the hell out of them...dropped them all the time, rolled over on them in bed, used them in the rain, cracked off parts of the compartment cover on accident, you name it...so for being about the least expensive variable voltage device imaginable, I'd say an average of 6 months each is pretty good

plus they convinced me that variable voltage is the way to go and now I have a higher end device on the way

anyone thinking about making/just buying one of these: go for it...they're very sturdy and if you aren't as clumsy as me, I'm sure they'll last you a good while

I have been using one for 3 months now as my exclusive PV. I just set it aside yesterday because I bought a Gripper. I assembled it. It didn't look pretty, but it worked. People were impressed at the clouds of vapor it put out. For the price, it cannot be beat. It looks a little worse for wear these days, but I know I can pick it up and fog up a room. The only suggestion I have is to apply a generous amount of epoxy around the base of the atty connector inside the mod. That is the only place where mine cracked. It has character now. That is how I see it. It will always be around me (at least as a backup).
