DIY Tutorial Pass-through Cable for Electronic Cigarettes

I created my own pass through cable for my Electronic Cigarettes as I was unable to find a pass through cable that worked for my m401. If you don’t know what a pass through cable is, it is a cable that allows you to use your Electronic Cigarette while directly connected to a power source without using a battery.

What will I need?

Soldering Iron with a fine tip

About a foot of thin solder

An old USB mouse you no longer need

A momentary switch (This switch engages while depressed.)

About 6-12 inches of 12 gauge electrical wire

An Electronic Cigarette Atomizer

Some electrical tape

Instructions:

Cut the USB cable of the mouse, very close to the mouse itself.

Strip the outer plastic coating off of the USB cable, about 4 inches will do.

Inside you will find several wires, cut all the wires except the red and black wires. When you are done, only the red and black wires will be showing.

Strip about ¼ inch off of the red wire and about ½ inch off of the black wire.

Solder the red wire from the USB cable to the inner connection on the Atomizer. The red highlighted area in Figure 2. Be sure not to cover the center hole of the Atomizer, if you do it will not work. This is where a fine soldering tip will come in handy. If you only use a small bit of solder, you should be ok.

Solder the black wire from the USB cable to one side of your momentary switch.

Solder a new wire from the momentary switch to the threading of the Atomizer, the green area in Figure 2.

Then tape it all up with electrical tape so none of the wires touch and so it provides support for the switch.

Disclaimer: It is possible you could damage your atomizer or the device supplying the USB power when building or using this device. I do not in any way endorse Electronic Cigarettes and at this time I do not know of any FDA approved Electronic Cigarettes. Also note, I have only tested this one the M401 Electronic Cigarette Atomizer, however, I think it will work with just about any Atomizer.

Tips:

When removing the filter, there isn’t a whole of material to grab onto. Your best bet is a twist and pull. If you’re only dripping, you can always attach the filter loosely.

Pressing the button a second before dragging on the filter will give you a more powerful hit. I find this device to give me a stronger hit to begin with, when compared to battery style.

There is no automatic shut off like the battery style, so be careful when taking a drag.
