By only 20 minutes the battery can be charged 80%, and 40 minutes to full charging.Two charging ports are available: a micro USB port and a 510 threaded USB port. 510 thread USB charger is compatible with most products.

Yes, our cartridges are refillable. The procedure for refilling the oil is almost the same as the first time.

Is it necessary to preheat my oil before vaping?

This usually depends on the state of your oil. If, for any reason, your oil is thick or appears to be crystalline and solid, then we recommend turning on the preheat mode.  In the opposite case, you can ignore this step. The general vape pen preheating setting is 15s. You can heat it for 15 seconds first, drop the oil and wait for a few seconds because the heat will gradually increase the temperature of the concentrated liquid.
