Gathering Materials: iPhone charging cable, wax coil, battery, button, and a casing for assembly
The iPhone charging cable is the backbone of this project, but not just any cable will do. Opt for a damaged or non-functional cable, as you’ll need to strip and repurpose its wires. The Lightning connector end is irrelevant here; focus on the USB end, which contains the power and ground wires essential for connecting the battery and coil. Ensure the cable is long enough to reach from the battery to the coil without strain, typically 4–6 inches of usable wire after stripping.
Next, the wax coil is the heart of the device, responsible for heating the wax. Choose a coil with a resistance between 1.5–2.5 ohms for optimal performance. Lower resistance coils heat faster but drain the battery quicker, while higher resistance coils are more energy-efficient but slower to heat. If you’re unsure, a 2.0-ohm coil strikes a balance, suitable for most users. Always inspect the coil for defects like loose wraps or exposed wires, as these can cause shorts or uneven heating.
The battery is the power source, and selecting the right one is critical. A single 18650 battery (3.7V, 2000–3000mAh) is ideal for this project, offering a balance of power and portability. Avoid overloading the circuit by using higher-voltage batteries or multiple cells in series. Ensure the battery has a protection circuit to prevent over-discharge or short circuits. Always handle batteries with care, avoiding punctures or exposure to extreme temperatures, which can cause leaks or fires.
The button serves as the activation switch, and its placement is key. Choose a small, tactile button with a low profile to fit within the casing. Solder the button in series with the battery and coil, ensuring it breaks the circuit when inactive. Test the button’s responsiveness before final assembly, as a faulty switch can render the device unusable. Position it ergonomically, allowing for easy access during use without accidental activation.
Finally, the casing ties everything together, providing structure and safety. A cylindrical metal or plastic tube with a diameter of 1–1.5 inches works well, offering enough space for components while maintaining portability. Ensure the casing has ventilation holes near the coil to dissipate heat and prevent overheating. Secure all components with electrical tape or heat-shrink tubing to avoid short circuits. A well-designed casing not only protects the internals but also enhances the device’s aesthetic appeal, making it functional and discreet.

Disassembling Cable: Carefully strip and separate iPhone wire components for repurposing
The iPhone charging cable, a ubiquitous accessory, holds hidden potential beyond its intended use. Disassembling it reveals a treasure trove of components ripe for repurposing, particularly in crafting a wax pen. The key lies in carefully stripping and separating the wire's intricate layers, a process demanding precision and patience.
Before wielding your tools, understand the cable's anatomy. Beneath the protective outer sheath lies a braided shield, followed by four colored wires: red, green, white, and blue. Each wire serves a specific purpose in data and power transmission, but for our wax pen, we're interested in their conductive properties and structural integrity.
Disassembly: A Delicate Dance
Begin by gently scoring the outer sheath with a hobby knife, taking care not to cut into the braided shield beneath. Peel away the sheath, revealing the shield's metallic weave. Carefully unwind the shield, exposing the four colored wires. Using wire strippers, remove approximately 1/4 inch of insulation from the end of each wire, exposing the copper strands within. Be meticulous; nicking the delicate strands can compromise their conductivity.
Separation and Preparation:
Now, separate the wires based on their intended use in your wax pen. The red and green wires, typically carrying power, are ideal for the heating element. Twist their exposed strands together, creating a single, sturdy conductor. The white and blue wires, often used for data, can be utilized for structural support or decorative elements. Consider stripping additional insulation from these wires to expose more length for creative manipulation.
Caution and Creativity:
Remember, safety is paramount. Always disconnect the cable from any power source before disassembly. The exposed wires can carry residual charge, so handle them with care. Once disassembled, let your creativity flow. Experiment with different wire configurations for the heating element, explore decorative weaving techniques with the braided shield, and consider incorporating other materials like wood or metal for a unique wax pen design.

Building Coil: Wrap wire around a mandrel to create a functional wax coil
The heart of any wax pen is its coil, and crafting one from iPhone wires requires precision and patience. Begin by selecting a suitable mandrel—a cylindrical object around which you’ll wrap the wire. Common choices include screws, drill bits, or even pens, with diameters ranging from 1.5mm to 3mm depending on your desired coil size. The wire itself, salvaged from iPhone charging cables, should be stripped of its insulation to expose the conductive core. Typically, these wires are made of copper, ensuring good conductivity for efficient heating.
Wrapping the wire is both an art and a science. Hold the mandrel firmly and start winding the wire tightly, ensuring each loop sits flush against the last. Aim for 5 to 7 wraps for a standard coil, but adjust based on your wax pen’s specifications. Consistency is key—irregular spacing can lead to hot spots or uneven heating. Once wrapped, carefully slide the coil off the mandrel, maintaining its shape. Trim any excess wire, leaving just enough length to connect it to your pen’s power source.
While the process seems straightforward, pitfalls abound. Over-tightening the wire can cause it to break, while loose wraps reduce surface area and efficiency. Test your coil’s resistance using a multimeter; aim for a range of 0.8 to 1.5 ohms for optimal performance. If resistance is too high, gently adjust the wraps to increase contact points. Conversely, if it’s too low, remove a wrap or two to reduce conductivity.
The final step is integration. Attach the coil’s leads to your wax pen’s battery terminals, ensuring a secure connection. Insulate any exposed wire with heat-shrink tubing to prevent short circuits. When activated, the coil should heat evenly, vaporizing wax without burning it. This DIY approach not only saves money but also offers a deeper understanding of your device’s mechanics, empowering you to troubleshoot or customize as needed.
In essence, building a wax coil from iPhone wires is a blend of craftsmanship and technical know-how. With the right tools, attention to detail, and a bit of experimentation, you can create a functional, efficient coil tailored to your vaping needs. It’s a rewarding project that bridges the gap between technology and creativity, turning discarded materials into something both practical and personal.
