AAfter the coil is burnt, please replace a new pod or a new coil, and it is not recommended to continue to use it.
Usually there are three problems that could cause coil burnt:
1) one is that the coil reaches its maximum lifespan. This is a normal;
2) the other is caused by improper personal use. Such as the new coil is not primed well (usually you needs to wait for 10 minutes after filling when use a new coil for the first time); and if the e-liquid level is below the “MIN” line during use, it will cause coil burnt;
3) in addition, the use of too thick e-liquid can also cause coil burning, and you can replace the e-liquid with a thinner one.
