Dual External Battery Mods are the base part of traditional vaping kits which has space inside to insert two external batteries used to power your device. Regardless of whether the vape is rechargeable or designed for singular-use, all vaping kits require a battery to supply electricity to the heating component within the E-Liquid Chamber, otherwise the coil would not be able to heat up and create vapour from your E-Liquid. These types of Vape Mods require two separate external battery cells, as they are not manufactured with an internally built-in battery. One of the many benefits to External Battery Mods is the ability to swap out the batteries from within the machine, making it more cost-effective for long-term vapers that have noticed their original external battery no longer holds as much charge as when it was first purchased. For vapers that do not wish to replace the batteries within their mods, we recommend taking a look at our selection of Internally Built-In Battery Mods, as these mods will not require a separate battery. Please note that External Battery Vape Mods do not come with the batteries required, and can be purchased in combination with your new mod or kit at a discounted price with the drop-down menu on each external battery mod page.
