Source Slim 4 Review - The Chill Bud

After the SOURCE Orb 4 “blew the socks off” The Chill Bud, they were excited to receive the SOURCE Slim 4 to review next!

I knew I’d like the Source Slim 4 because I loved the Orb 4 from Source Vapes. What I didn’t know was just how much I’d like the Slim 4!”
-The Chill Bud

The SOURCE Slim 4 is the stocky little brother of the Orb 4. At only 4.7 inches tall and weighing 3.6 ounces, portability is a noteworthy feature of this product. This vape pen features a Stainless Steel 303 build, SOURCE volt mini battery AND a built-in Silicone container. Including 3 temperature settings and a 5-setting variable airflow system, this pen is a winner. Two atomizers are included with purchase, BUT the slim 4 is compatible with all 9 Source 4 series atomizers!

What’s Included?

  • 1x SOURCE slim 4 Attachment
  • 1x SOURCE volt mini battery w/ Built-in Silicone Container
  • 1x Small Dab Tool
  • 1x micro USB Charging Cable
  • 1x SOURCEvapes Large Travel Case
  • 1x Microfiber Cleaning Cloth
  • 1x 4 Series Quartz Double Coil
  • 1x 4 Series SOURCE nail Quartz atomizer (With Removable Bucket)


Concentrate Storage

One feature the Chill Bud noticed right away was the inclusion of a small silicone concentrate compartment. Found at the bottom of the unit, this screw-on container allows you to carry your favorite concentrates without worry.

Screw-on silicone compartment!

“It’s a little quality of life feature that’s easy to overlook, but I feel this attention to detail permeates throughout the entire vaporizer and proves that SV cares about your overall vaporizing experience.”
-The Chill Bud

Variable Airflow System

The Chill Bud was happy to discover that the Slim 4 featured the same variable airflow system (VAS) that they loved so much in the Orb 4! This new and improved VAS can adjust a dab to the exact preference of the user. Preference for strength, length and flavor of a dab may change on a daily basis, and SOURCE Slim 4 (and Orb 4) supports the need for variety!

For a customized airflow experience, expose or conceal the 5 tiny airflow holes on each side with a rotating cover. This means you decide whether more or less fresh air enters the unit as you draw the vapor.

3-temp settings and the variable airflow system allow the customer to modify their vaporizing experience to fit their needs/taste.

“The whole design of the Source Slim 4 is straightforward and easy to use. Right from the get-go I was pulling huge clouds from this pen.”
-The Chill Bud


Strong Stainless Steel

The SOURCE Slim 4 is encased in gorgeous dark stainless steel, which gives both a durable and high-quality feel.

This compact unit is easily stashed away and carried in a bag or pocket, making it a practical and portable choice. The strong materials used in the making of this vape pen mean you don’t have to worry about anything breaking off or causing stress on the go.  

Stainless steel construction and well machined components give the Source Slim 4 a very sturdy feel that gives you the confidence to bring it just about anywhere.”
-The Chill Bud



New SOURCE 4 Series atomizers have been completely redesigned with a full Stainless Steel 303 construction. This is the healthiest option for material ever used on a vaporizer pen.

The Slim 4 comes with 2 x 4 Series atomizers; a Quartz Double atomizer made with Grade 1 Titanium and a coil-less Quartz SOURCE nail atomizer. Nail atomizers feature an easy-to-clean removable bucket (3 types available: Grade 2 Titanium, Ceramic, or Quartz.)

A complete range of flavors and strengths is certain with these revolutionary atomizers. The Chill Bud chose the coil-less quartz bucket atomizer as their hands down favorite.

“SourceVapes prides themselves on their high-quality atomizers, with a stainless steel construction and grade 1 titanium coils it’s no secret why they’re so damn proud!”
-The Chill Bud


For the level of quality and function of this pen, $89.95 is a steal!  All series 4 atomizers from Source Vapes fit both the Orb 4 and the Slim 4.
