Hello, I will try to assist you here, but you have provided limited information to do so most effectively.
Do you have a bottle of e liquid? If not, you will need to buy some.
Have you tried adding more e liquid into it? If not, try this first providing you have some liquid.
If you have liquid, and adding it in then waiting 1-2 minutes for the coil to wick the liquid resulted in a burnt taste, then you most likely tried to vape on the
device when it was empty, and burned the wicking material around the coil. If this is the case, you will need to first replace the coil inside the base of the top section of the device. Then refill it with liquid and use normally after giving it 1-2 minutes for the new liquid to soak into the new coil.
Some of the units you have came with a spare coil, other may not have. If you do not have any spare
coils, you will need to buy some.
If this does not help, please provide as many details as you can, such as:
If you tried anything above, what was the result?
Where you are, country/state/city etc so we might help point you to a local store if needed.
What you have or do not have such as spare
coils, liquid etc.
