Hey so I bought a nitecore charger today the new i2 and I think it might be fake. I bought it from a local vape shop and I've used it once tonight and worked ok but I checked the validation code and it said it had already been validated. Could this have been done by the vape shop or is it a fake?. If unfortunately it is a fake does that mean it is unsafe to use. My biggest worry is my vape (smok alien) blowing up and if i use the fake will it cause this.
