A long-lasting, easy-to-use 1000mAh Battery.
With a 1000mAh capacity, the Innokin T18 battery will last many people for a full day's use, but bear in mind that this can vary greatly depending on your vaping habits and preferences.
If the button doesn't light up when pressed, then it's either locked or completely drained of charge. Press the button 3 times quickly to unlock it, and if there's still nothing happening then give it a good charge and try again.
The Innokin T18 battery has a capacity of 1000mAh, so with a 1000mA (1A) charger it will take about an hour. With a 500mA charger it will take about 2 hours.
It's specifically designed to work with the Innokin T18E Tank, however it can be used to power any tank/clearomizer with a 510 fitting, so long as the resistance of the coil is at least 1.2ohm.
