The battery supplies power to the device. The battery in a disposable vape can usually supply several hundred puffs before it dies. At that point, you’ll need to replace the device unless the battery is rechargeable. If you have a disposable vape with a USB port, you can recharge the battery when it dies and continue using the device until it runs out of vape juice.
The logic board controls the functions of a disposable vape. It interfaces with the battery and the puff sensor to deliver power to the heating coil when you puff on the device. The logic board is also responsible for the device’s safety functions, which may include automatic overheating, short circuits and low voltage protection. In a rechargeable disposable vape, the logic board also handles the charging function and ensures that the battery stops charging when it reaches its target voltage.
The wick holds the disposable vape’s e-liquid and supplies the heating coil with vape juice. In most disposable vapes, the wick is wrapped around the coil. When you vape, the coil vaporizes the vape juice in the inner part of the wick. After you puff on the device, the process of absorption brings more vape juice to the coil from the outer part of the wick. This continues until the wick is dry, and at that point, it’s time to replace the device.
The coil is a heating element made from a metal or alloy with a high electrical resistance. When electricity passes through the coil, the resistance causes the coil to produce heat, which vaporizes the e-liquid.
