Vaping typically uses "18650" batteries, which consist of two parts: 18 and 65. Here, 18 indicates the diameter in millimeters, while 65 refers to its length. Thus, an 18650 battery measures 18 mm in diameter and 65 mm in length. The "510" designation refers to the female screw thread design on one end, featuring 10 x 5mm threads, known for being the most compatible connection type for vape pens worldwide, ensuring a secure connection. Batteries referred to as 21700 are larger, higher-capacity versions of 18650 batteries, maintaining the same nominal voltage of 3.6/3.7V, and are meant to replace 18650 in EV battery packs. They have a capacity of about 4,000 to 5,000 mAh. Choosing the correct charger for the specific vaporizer or box mod is crucial to ensure compatibility between the vape pen and charger. While not overly complicated, buying a replacement charger separately can complicate the process.
