A zirconia-ceramic mouthpiece and a 14 mm bong adapter round off the device. In the price comparison it is worth checking the offers from various European shops.
The Coil King AIO is slim and discreet — hardly recognizable as a vaporizer at first glance. The metal or plastic housing protects the electronics. One-button operation makes it intuitive to use. It fits in any shirt pocket and typically weighs under 50 grams.
Heating element
Concentrate pens typically use quartz, ceramic or titanium coils that heat the wax directly. Quartz delivers the purest flavor, ceramic heats more evenly, titanium is the most durable. Some models offer replaceable coils for different material types.
Loading and vaping
Place a rice-grain-sized portion of concentrate directly onto the coil. Don't overload — too much material clogs the coil and worsens the flavor. Tap the button briefly (preheat) or hold it down to vape. Draw slowly and evenly. Let the coil run on briefly after the draw.
How Do I Charge the Battery Properly?
Most concentrate pens use small batteries (300-900 mAh) for 20-50 draws per charge. The available sources do not indicate a duration for a full battery charge. Burn off the coil briefly after each use. Soak the coil in ISO every few weeks. Replace coils when flavor fades — typically every 2-4 weeks.
