Electronic cigarettes with built-in battery

Built-in

— a battery built into a battery mod that cannot be removed or replaced by the user. Such batteries are usually made using Li-Ion or Li-Pol technology. There are no fundamental differences between these technologies, both varieties are distinguished by good capacity, compact size and ease of use; the main difference is that lithium-ion batteries are slightly cheaper, while lithium-polymer batteries are more resistant to charge-discharge disturbances.

If we compare this option with removable batteries, then the main advantages of built-in batteries are compactness and ease of use: the design of mods with such power supply has a charge-discharge controller by default, so the user does not need to specifically monitor the operating mode (for models for replaceable batteries such a controller is far from mandatory). Also, the advantages include the fact that the power supply is immediately included in the package, you do not need to look for it separately. The main disadvantage of this option is actually the inability to quickly remove the battery. As a result, when the charge is exhausted, you will have to spend time recharging, and when the battery fails, take the mod to the workshop or change it entirely. In addition, the power of models with built-in batteries is relatively low — there are practically no options for more than 200 W among them. However, for most users, these points are not critical.
