"Built-in battery" and "18650 lithium battery"
According to the different types of batteries used, common electronic cigarette hosts can be divided into "built-in batteries" and "18650" batteries. The built-in battery means that the host has already included a battery when it leaves the factory, and the user does not need to buy another battery and charger, and can charge the host through the USB interface. The most typical electronic cigarette device is the "EGO" category, usually in the form of this "built-in battery".
"18650 battery" means that the host does not contain a battery when it leaves the factory, and the user needs to purchase another battery before it can be used. There are many friends who buy electronic cigarettes for the first time, they ignore this point, and after receiving the product, they cannot use it because there is no battery.
In the introduction of the product, the host with built-in battery will usually be marked with the words "built-in battery" or "xxxxmAh" battery capacity, while the description of the removable battery will be marked with "removable battery", "18650 battery powered" or "no Batteries included". Consumers should pay attention to relevant information and consult the merchant for confirmation before purchasing, so as to avoid purchasing electronic cigarette equipment that is different from what they need.
The advantage of a built-in battery is that it is safe, lightweight and easy to use. Users can use it after purchasing. The disadvantage is that the battery is encapsulated inside the host. After the power is exhausted, it can only be charged, and the backup battery cannot be replaced. If there is no power supply, it cannot be used continuously. Moreover, once the host battery is damaged, the user cannot replace it and can only return it to the factory, which is expensive.
The advantage of "18650" battery is that it is widely used and replaceable. If the battery power is exhausted, the spare battery can be replaced to continue to use, and the user can charge the replaced battery at a convenient time, and the use of the electronic cigarette will not be affected due to the exhaustion of the battery power.
Another advantage of the 18650 battery is that it can be widely used in electronic cigarette devices. Most of the hosts are powered by 18650 batteries. If you buy a new console, the original 18650 battery can continue to be used in the new console.
The disadvantage of 18650 lithium battery is that users need to have certain battery knowledge to buy more ideal and suitable products. Due to the large output current of electronic cigarette equipment, the 18650 battery used usually requires a high discharge current, which is the so-called "power battery". If a battery with a low discharge capacity is used in a device with a high output, it may damage the device and the battery, and also affect the normal use of the host. Therefore, when buying a host powered by 18650, you also need to buy a suitable battery. If you want to prolong the service life of the battery, you also need to buy a suitable charger. Compared with the built-in battery host, it is more troublesome to buy.
