The battery is the part off the electronic cigarette that provides the power to the atomiser so it can heat up the e-liquid to produce the vapour. We have a wide range of batteries available with different power and colour options plus advanced versions offering greater functionality. Our eGo range includes various safety features such a 5 click on/off child lock and 10 second automatic cut off to prevent over heating. The standard range is available in 3 powers and in various colours. The higher powers are physically longer, just choose your favourite based on size preference versus how long it lasts between charges. More advanced vapers might prefer our LCD models or variable vape versions. Please check out our product descriptions for detailed information on each type.
