The Coil King AIO is slim and discreet — barely recognizable as a vaporizer at first glance. Metal or plastic housing protects the electronics. Single-button operation keeps things intuitive. Fits in a shirt pocket and typically weighs under 50 grams.
Heating Element
Concentrate pens typically use quartz, ceramic, or titanium coils that heat wax directly. Quartz delivers the purest flavor, ceramic heats more evenly, titanium is the most durable. Some models offer swappable coils for different material types.
Loading and Vaping
Place a rice-grain sized portion of concentrate directly on the coil. Don't overload — too much material clogs the coil and hurts flavor. Tap the button briefly (preheat) or hold to vape. Draw slowly and steadily. Let the coil run briefly after your draw.
How Do I Charge the Battery Properly?
Most concentrate pens use small batteries (300-900mAh) for 20-50 draws per charge. USB charging in 30-60 minutes. Burn off the coil briefly after each use. Soak the coil in ISO every few weeks. Replace coils when flavor drops — typically every 2-4 weeks.
Frequently Asked Questions
No, pure concentrate devices are designed for waxes and extracts only. Dry herbs would damage the coil.
With daily use, every 2-4 weeks. Signs: burnt taste, less vapor, visible coil discoloration.
With conduction, material is heated through direct contact with a hot surface. With convection, hot air flows through the material. Convection is considered more efficient and flavorful.
For optimal performance, we recommend light cleaning after each session and thorough cleaning with isopropyl alcohol every 1-2 weeks.
170-185C for light vapor, 185-200C for balanced effects, 200-210C for maximum extraction. Start low and work your way up.
