21700 BATTERIES

21700 batteries are a popular choice for high-performance e-cigarettes and vaping devices due to their larger size compared to the more common 18650 batteries, offering increased capacity and higher discharge rates. Typically, they provide anywhere from 3000 to 5000 mAh, allowing for longer usage times between charges, which is especially valuable for users who prefer extended vaping sessions. However, it’s essential to use high-quality, reputable brands to ensure safety and performance, as well as to follow proper charging practices to avoid risks such as overheating or battery failure.
