Source Vapes Slim 4 Wax Vaporizer Travel Kit

Source Vapes – Slim 4 Vaporizer

Source Vapes is a vape company that prides them self on innovative designs and constructing vaporizers out of the highest grade, lab-tested materials.

After having positive experiences with the Source Vapes Orb wax pen review, we were curious to see how Source’s Slim 4 vaporizer would hold up.

The Slim 4 vape was designed to vaporize waxes and thick cannabis concentrates.

Its polished, gunmetal gray, stainless steel body make it one sexy, handheld vaporizer… and also a fingerprint magnet!

The Source Vapes Slim 4 does an excellent job of transferring flavor and has the best airflow control on any wax pen we’ve tried so far.

Then screw the attachment into the threaded base of the battery.

Drop in a small dab of your favorite wax onto the coils or into the quartz bucket. Then pop on the cap to create a tight seal.

Use five rapid clicks of the button on the face of the battery to power on/off and three rapid clicks to cycle through each of the three volt settings.

Volt settings are indicated by the button’s color coded light:

  • Low voltage = green
  • Medium voltage = blue
  • Red voltage = high

Press and hold down the power button for the duration of each inhale.

Our Experience

We first tested out the Slim 4 vape using the quartz coil-less atomizer and some tasty Legion of Bloom rosin.

The Slim 4 did an excellent job in transferring the clean crisp taste of that rosin.

While the quartz coil-less atomizer doesn’t deliver the largest rips, it does produce a consistently clean taste. To get the best vapor draws, hold down the power button for a few seconds to pre-heat the quartz cup, then take several 3-5 second draws instead of one huge, long rip.

When using the dual titanium coil, we were able to get fatter rips. The issue we had with this pen is that it takes a while to pre-heat the coils. If you take too many rips in a row, you’ll get large amounts of vapor but the wax concentrate can begin to lose its flavor and become somewhat harsh.

You will immediately notice that the Slim 4 has some of the most incredible airflow of any wax vape pen.

The only draw back is that the airflow control dial can be difficult to adjust. Because of its polished steel finish, the dial can be hard to grip, especially if you have moisturized or greasy hands. Fortunately, once you find the airflow you’re happy with, you can set it and forget it.

Final Thoughts

At under $90, the Source Vapes Slim 4 Travel kit is good deal.

The Slim 4 for vaporizer offers two great atomizer options to suit your taste, one slick looking battery, and a handy hidden stash compartment built right into the vape, to hold your cannabis extracts.

The included hard case is also a nice touch. With a vape made of quality materials like the Slim 4 and backed by a life-time warranty, you can’t go wrong.
