Box mods refer to a power unit you can connect to a tank. Some contain a built-in battery, while others need batteries, which are available separately. The battery delivers the power required to heat the coil inside the tank, which vapourises the e-liquid and creates the puffs or clouds of flavours you inhale. With some of the largest brands available, such as Smok and Aspire, we aim to provide choice and value for money, keeping them as competitive as possible.
Some mods are for smaller tanks requiring low wattage, while others are for larger sub-ohm setups delivering more power. Double battery setups are bulkier, but you will have greater capacity, resulting in more extended periods between charging. The single-battery mods tend to be more compact and use an 18650 battery; we always recommend charging your battery outside your mod, as setting through your device can be slow and potentially dangerous in some cases.
