Pulsar DL Tandem Dual 510 Vape Cart Battery

The Pulsar DL Tandem Dual 510 Vape Cart Battery is a feature-packed dual-cartridge vaporizer that lets you load two 510-thread oil carts at once and fire them independently or simultaneously. With a 650mAh battery, five voltage settings, an LCD display, and a built-in preheat function, the DL Tandem gives you full control over every session — whether you’re switching between strains, mixing flavors, or doubling up for heavier clouds. It even ships with a 14mm male water pipe adapter for filtered rips through your favorite glass. If you’ve been looking for a dual cartridge vape battery that doesn’t cut corners, this is it.

Dual Cartridge Vaping — Independent or Simultaneous

The DL Tandem houses two separate 510-threaded cartridge ports in a single compact body. A dedicated selector button on the front lets you toggle between the left cart, the right cart, or both at once. Fire each cart independently to switch between different strains or flavor profiles throughout your session, or engage both simultaneously for massive clouds and amplified potency. Each cartridge port accepts carts up to 14mm x 59mm in size (up to 2g capacity), and the magnetic cartridge magazine snaps securely into the housing for a rattle-free connection. Just screw your carts into the threaded adapters, attach the magazine magnetically, and you’re set.

Five Independent Voltage Settings with LCD Display

Dial in your vapor with five preset voltage levels — 1.8V, 2.4V, 2.8V, 3.4V, and 3.8V — and adjust each cart’s voltage independently for fully custom combinations. Low voltages preserve terpene-rich flavor, while higher settings produce thicker, denser vapor. The front-facing LCD screen displays the active voltage for each cart as well as real-time battery life, so you always know exactly where your session stands. No guessing, no wasted hits — just precision control at a glance.

Button-Fire + Auto-Draw Operation

The DL Tandem gives you two ways to hit. Use the main button to manually fire your carts with full timing control, or switch to optional auto-draw mode for hands-free, inhale-activated puffing once the device is powered on. Whether you prefer the tactile feedback of button-firing or the convenience of draw-activation, the Tandem adapts to your style. Power on/off with five rapid clicks of the main button.

15-Second Preheat Function

Thick oils and cold-weather sessions can cause clogs and weak draws. The DL Tandem’s built-in preheat function gently warms your cartridges for up to 15 seconds, loosening concentrates and priming wicks before you inhale. This prevents dry hits, clears minor clogs, and ensures smooth, consistent vapor from the very first pull — especially useful for high-viscosity distillates and live resin carts.

14mm Male Water Pipe Adapter Included

Take your dual-cart sessions to the next level. The DL Tandem includes a 14mm male water pipe adapter that lets you connect the vaporizer directly to any bong or dab rig with a 14mm female slide joint. Water filtration cools the vapor and smooths out each hit, combining the convenience of cartridge vaping with the refinement of glass. It’s a game-changer for home sessions when you want maximum flavor and comfort.

650mAh Battery with USB-C Charging

Powering two cartridges demands serious battery life, and the DL Tandem delivers with a 650mAh internal cell. That’s enough capacity for all-day use even when firing both carts simultaneously. When it’s time to recharge, the USB-C port provides fast, modern charging — no flipping the cable, no long waits. The LCD screen tracks battery percentage in real time so you’re never caught off guard.

Compact, Durable & Discreet Design

Despite packing dual carts and a full feature set, the DL Tandem measures just 96mm x 51.7mm x 24mm — compact enough to palm or pocket without bulk. The durable plastic housing fully conceals both cartridges when the magazine is attached, and the magnetic silicone mouthpiece provides a comfortable, tooth-friendly draw that won’t clack against your teeth. The mouthpiece pops off easily for cleaning and maintenance. Available in multiple colorways including the Thermochromic Series with heat-reactive, color-changing shells.
